Corn earworms – Responsible for your yield loss!

The hybrid of few pests is causing a havoc for the crop cultivators. The corn earworm and bollworms are few of the insects whose hybrids are difficult to manage. We have known about bollworm in one of the previous blogs. Now, it’s time to know about corn earworms.

Let me tell you that the estimated annual cost of the damage caused by corn earworms is more than US$100 million.

Corn earworms are mostly found in the temperate and tropical regions of North America and the eastern United States. They regularly migrate from southern regions to northern regions depending upon the winter conditions. Corn earworms are considered as the second most economic species in North America.

Corn earworms have the ability to lay eggs around 500 to 3000 which are deposited on leaf hairs and corn silks. In the larval stage after hatching from eggs, they feed on reproductive structures of plants. The larval stage of corn earworms is considered as the most destructive stage.

Mature larvae usually have orange heads, black thorax plates, and the body color mostly black. Their body colors can also be brown, pink, green, and yellow with many thorny micro spines. They usually migrate to the soil where they pupate for 12 to 16 days. They pupate 5 to 10 cm below the earth surface.

Adult moths have forewings that are yellowish brown in color and have a dark spot located in the center of their body. The moths have a wingspan ranging from 32 to 45mm and live over thirty days in optimal condition Adult moths collect nectar or other plant exudates from a large number of plants, and live for 12 to 16 days.

Corn earworms have the large host plant range encompassing corn and many other crop plants such as tomato, cabbage, eggplant, cucumber, melon, okra, pea, sweet potato, etc.

The corn earworm feeds on every part of corn, including the kernels. Severe feeding at the tip of kernels allows entry for diseases and mold growth. Larvae penetrate 9 to 15 cm into the ear, with deeper penetration occurring as the kernels harden. Larvae do not eat the hard kernels, but take bites out of many kernels, lowering the quality of the corn for processing.

There are various ways for combating against corn earworms. But those methods are found ineffective as these smart insects have developed resistance against all the methods. They are attacking the crops and the evidence for the same is noted below:

Hybrid swarm of ‘mega-pests’ threatens crops worldwide, warn scientists

New strain could be significant biosecurity risk and has potential to go ‘completely undetected’

Josh Gabbatiss Science Correspondent Saturday 7 April 2018

A pair of major agricultural pests have combined to produce a “mega-pest” that could threaten crops around the world.

Losses from the original pest species, cotton bollworms and corn earworms, already amounts to billions of dollars worth of food.

But a hybrid of the two, shows signs of rapidly developing resistance to pesticides and it scientists fear it could cross international boundaries undetected, wiping out all the crops it comes across.

Insect resistant Bt corn losing effectiveness against earworm, study finds

Graham Binder | January 23, 2017 | Phys.org

A UMD-led study provides new evidence of a decline in the effectiveness of genetically engineered traits widely used to protect corn crops from insects. This loss of effectiveness could damage U.S. corn production and spur increased use of potentially harmful insecticides.

Corn crops engineered with genes from the bacterium Bacillus thuringiensis (Bt) express specific proteins called Cry proteins (endotoxins) that, when ingested, kill crop pests like the earworm. Because the Bt protein is very selective…[and] less harmful than broad-spectrum insecticides.

In 2015, 81 percent of all corn planted was genetically engineered with Bt. Recently however, certain states, most notably North Carolina and Georgia, have experienced increased corn ear damage, setting the stage for risk of damage to corn production across a large portion of the country.

Since from the evidence we came to know that the corn earworms have developed resistance to many pesticides. By manipulation of crops genes we do develop the crop resistance to many insects but at the time the insects also develop resistance.

Hence there is a need of using an external but effective method to save our crops from these pesky corn earworms.

Such a method is to use Termirepel^TM an eco-friendly insect aversive. Termirepel^TM is developed on the basis of green chemistry and technology to protect the crops against a broad spectrum of insects.

Termirepel^TM can be used in the fields by various ways in order to provide the best protection to crops from corn earworms.

Termirepel^TM works on the mechanism of repellency. It temporarily inhibits the mating cycle of the insects. The product impairs the ability of the insects to reproduce, that is the insects will not lay eggs or the laid eggs will be infertile. The product causes feeding disruption in an insect by triggering an unpleasant reaction within the insect which might try to feed on the application. The product temporarily blocks the reproduction system of the insects by hindering the release of the vital hormones for growth.

Termirepel^TM is an extremely low concern, low toxic, nonhazardous, non-carcinogenic and non-mutagenic insect aversive.

Termirepel^TM provides you an economically feasible and effective solution against insects.

Termirepel^TM does not kill or cause harm to insects as well as to the environment which indirectly helps to maintain the ecological balance.

Termirepel™ is thermally stable and does not degrade on exposure to heat and sunlight. It does not kill or harm the insect but repels them. It does not volatilize and does not degrade the soil. It is RoHS, RoHS2, ISO, REACH, APVMA, NEA compliant and FIFRA exempted.

Don’t you think you must take the immediate step to protect the crops from these major agriculture pests?

Nuisance caused by mountain pine beetles

The forest cover in North America apparently turns red. But isn’t it supposed to be green?

The trees can’t help themselves at times. These are the times when the mountain pine beetles attack these trees and disturb their appearance.

The mountain beetle menace is not limited to the appearance of the trees. They literally kill the trees once they attack the trees.

Mountain Pine Beetles just don’t attack trees from the mountains. They’ve made their way to cities and towns, sometimes even catching a ride into town on firewood.

The mountain pine beetle has a one-year life cycle in most of its range but may take more or less time to complete its development, depending on local temperatures. Adult beetles usually disperse in July or August, depending on the region, to colonize new host trees.

In western North America, the current outbreak of the mountain pine beetle and its microbial associates has destroyed wide areas of lodgepole pine forest, including more than 16 million of the 55 million hectares of forest in British Columbia.

According to an annual assessment by the United State’s forest service, 264,000 acres of trees in Colorado were infested by the mountain pine beetle at the beginning of 2013. This was much smaller than the 1.15 million acres that were affected in 2008 because the beetle has already killed off most of the vulnerable trees.

Beetle killed trees impede elk and elk hunters

November 25, 2014 By Kelsey Dayton

For 17 years Jeff Corson has owned property on the Medicine Bow National Forest near Baggs and Encampment. Walking through the woods, both hiking in the summer and stalking elk in the fall, he’s noticed more and more deadfall.

“It’s a lot harder for me to get around,” he said. “And there’s still a lot left to fall.”

As of 2013, more than half of Medicine Bow’s 1.3 million acres were impacted by the mountain pine beetle. The epidemic has receded, but in the aftermath, forests are left with thousands of acres of trees that are dead and falling. Those same trees that make it difficult for Corson to get around could also present challenges for elk on the move.

Small pine beetle destroying large Ocean County Park

By Nora Muchanic , Tuesday, June 14, 2016

LAKEWOOD, N.J. (WPVI) – Some of the trees in Lakewood, New Jersey have stood for over 100 years, planted by oil tycoon and conservationist John D. Rockefeller at what was once his country estate.

It’s now Ocean County’s flagship park where over 1,000 trees have recently been cut down due to an infestation of the relentless and aggressive southern pine beetle.

“If we don’t get a handle on it, these little pine beetles will destroy the trees. They go from one to another,” Ocean County Parks Superintendent Mary Jane Bavais said.

Rich Reenstra, the Ocean County forester, says the southern pine beetle is the size of a grain of rice. It bores into a tree’s bark to feed and breed, injecting a fungus that looks like a dark line.

“That fungus actually girdles the tree and kills below the bark the tree’s ability to transport water,” Reenstra said.

The beetles basically starve the tree, killing its leaves and causing bare branches. The trees try to fight back pushing the invaders out in a sticky ball of sap, but it doesn’t always work.

To stop the nuisance caused by these bugs there is a need for an effective solution and C Tech Corporation has one!

The unique product Termirepel^TM manufactured by C Tech Corporation is an anti-insect aversive which repels insects.

Termirepel^TM is available in the form of the masterbatch, which can be incorporated with the polymeric applications like tree guards, pipes, agricultural films, wires, and cables, etc. to keep insects at bay.

The product available in the form of liquid concentrate can be mixed in paints in a predetermined ratio and lacquer which can be applied topically on the applications.

The product available in the form of lacquer can be used as a topical application and can be applied on the tree trunks to keep the pests at a distance from the trees.

To keep the insects at the bay Termirepel^TM lacquer can be sprayed or coated on the tree trunks.

The product is also effective against a multitude of other insects and pests like beetles, mayflies, thrips, aphids, etc. The repelling mechanism of the product would ward off the boxelder bugs and other insects that could cause damage. Thus, by using Termirepel^TM would effectively ensure that the area around us remain safe and protected from the pests for a long period of time.

Why resort to killing when we can just repel them!?

Our product works on the mechanism of repellency. It temporarily inhibits the mating cycle of the insects. The product impairs the ability of the insects to reproduce, that is the insects will not lay eggs or the laid eggs will be infertile. The product causes feeding disruption in an insect by triggering an unpleasant reaction within the insect which might try to feed on the application. The product temporarily blocks the reproduction system of the insects by hindering the release of the vital hormones for growth.

Beware, they are invading- Japanese Beetles

Imagine certain beetles are attacking plants in your garden or fields and all you could do is nothing. An infestation of Japanese beetles can be very disheartening. They are a threat to gardeners and farmers everywhere because of their voracious appetite.

Japanese beetles are most active during warm, sunny days. The adults immediately begin feasting on whatever plants are available once they emerge from the ground in spring (June).

Japanese beetle (Popillia japonica) originates from north-eastern Asia where it is native in northern Japan and in the far east of Russia. In the USA, P. japonica is established in all states boarding, or east of the Mississippi River, with the possible exception of Florida. Several western states have isolated established populations of the beetle. The beetle has also spread in parts of South Africa, southeastern highlands of Australia, Tasmania, New Zealand and also in eastern Canada.

Japanese beetles are a menace insect pest in the home landscape, vegetable garden, and fruit orchard. With the potential to have large population numbers, they can be found eating almost any plant in sight. They have the potential to literally destroy some plants in a manner of hours.

Beetles can feed over an entire soybean field and cause their damage. They also defoliate asparagus, nearly all varieties of grapes, and many fruit-bearing trees, especially apple, cherry, plum, and peach. Beetles can aggregate and feed in large numbers on the fruit of early-ripening varieties of apple, peach, nectarine, plum, raspberries, and quince.

In the USA, adult Japanese beetle has been observed feeding on at least 295 species of plants in 79 plant families (Fleming, 1972a). These include small fruits, tree fruits, vegetable and garden crops, field crops, woody and herbaceous ornamentals, shade trees, various weeds, and many non-economic species. Maize is one field crop seriously damaged in North America. Economic damage has been recorded on a variety of species.

Japanese beetle larvae feed off the roots of grass plants and cover crops, so it’s important for farmers with cover crops to watch for beetle pressure. Once the larvae become a beetle, it only lives for 30 to 40 days. However, during that time it can cause significant crop damage.

Leaves are decimated and can no longer support the plant. When the leaves have many holes and gaps in their tissue, they are no longer able to spread nutrients effectively nor photosynthesize, and the whole plant will eventually die.

Japanese Beetles could wreak havoc on Colorado foliage this summer

Eric Lupher│Apr 14, 2018

DENVER — It’s that time of year when the trees start blooming and we all start planting. The Colorado Department of Agriculture, however, says the Japanese Beetle will once again wreak havoc on some of our landscapes come the summer months. The very invasive species first started showing up in Colorado in 2006 and they haven’t gone away. The adult beetles eat away at fruits and some tree leaves.

Hordes of Japanese beetles are invading Iowa vineyards
Donnelle Eller │July 15, 2017

Julianna and Andy Hrasky got a nasty surprise when they returned home last month: Thousands of Japanese beetles were eating their way through their western Iowa vineyard.
The pests are invading the state in numbers few Iowans have experienced before.

Grapes and other fruit trees and vines are among the pests’ favorite feasts, but they’re also eating foliage from trees, shrubs and flowers and wreaking havoc with home gardens and flower beds.

About 50-60 percent of Iowa vineyards are spraying pesticides for Japanese beetles, White said.
The Hraskys estimate the pests caused their winery about $20,000 in losses from the one variety. The couple must drop the fruit, with three-fourths of the foliage eaten away.

This shows that these small bugs can cause a huge bite. This menace needs to be stopped. Also, the solution to stop the nuisance has to be effective and environment-friendly.

Efforts are being made to control the spread of this pest. Using beetle traps, insecticidal soaps, even the insecticides. But all of these proved to be of no use. Research conducted at the University of Kentucky showed that the traps attract many more beetles than are actually caught.

Insecticidal soaps are not effective at controlling the Japanese beetle. The insecticides have adverse effects on human health. Also, it affects the non-target species.

C Tech Corporation has a solution to these Japanese beetle menace

C Tech Corporation has introduced an insect aversive named Termirepel^TM.

Termirepel^TM is extremely low toxic, thermally stable and does not degrade on exposure to heat and sunlight. It does not kill or harm the insect but repels them. It does not volatilize and does not degrade the soil. It is RoHS, RoHS2, REACH, ISO, APVMA, NEA compliant and FIFRA exempted.

Our Termirepel^TM masterbatch can be incorporated in the agricultural films, polymer materials, greenhouse films, polymer sprinklers, irrigation pipes, plastic parts from pumps and tractors used in the fields.

The product in form of liquid concentrate can be mixed in paints and be painted on the concrete walls around the farms and gardens. It can be applied to the warehouses where the fruits or crops are stored. The liquid concentrate is compatible with all kinds of paints and solvents.

Our lacquer product can be applied to already installed applications. The lacquer is compatible with most of the surfaces like metals, wood, polymers, concrete etc. It can be applied on the wooden fences around the farms and already installed pipes.

Termirepel^TM does not kill the target species but only repels them thus balancing the ecology and thus helping in maintaining the goal of sustainability.

Our products are a blend of green chemistry and smart technology. The product does not have any adverse effect on humans. Therefore significant in today’s time and date as ecology salvation has become the prime focus.

Tick Tick Tick errr Tick

Perhaps no feeling gives humans the creeps like that of finding a tick crawling on them and the same applies when they find a tick on their dog. There is frequently hysteria about the blood-sucking habits of ticks and the diseases they can potentially transmit to us and our pets.

Tick species are widely distributed around the world, but they tend to flourish more in countries with warm, humid climates, because they require a certain amount of moisture in the air to undergo metamorphosis, and because low temperatures inhibit their development from egg to larva. Ticks are also widely distributed among host taxa, which include marsupial and placental mammals, birds, reptiles such as snakes, iguanas, and lizards, and amphibians. Some of the most debilitating species occur in tropical countries. Tropical ticks affect most domestic animals and occur in Africa and the Caribbean.

In general, ticks are to be found wherever their host species occur. Migrating birds carry ticks with them on their journeys; a study of migratory birds passing through Egypt found more than half the bird species examined were carrying ticks. The species of tick often differed between the autumn and spring migrations, probably because of the seasonal periodicities of the different species.

Ticks can detect their hosts via body odor, temperature, moisture, and vibration. The sensory organ which helps in identification of potential hosts is located on the legs. Ticks are not able to fly or jump. When they identify the ideal host, ticks crawl until they find a suitable place to attach themselves. They prefer skin on the area of head, neck, and ears because it is soft and can be penetrated easily.

Did you know that ticks require a blood meal to survive?! That’s right! Ticks require blood for sustenance. If a tick bites you, it’ll probably stick around for a few days. A single adult female can consume 0.6 mL of blood or more. The first thing the tick will likely do is look for a good spot to set up its proverbial picnic basket. Then it starts meal prep, sometimes for as long as two hours. Since some ticks are relatively small, the larva can be smaller than a millimeter, there’s a good chance you won’t notice one’s on you. Next, the tick burrows its creepy little head into your skin, unpacks its feeding tube, and spits out a cocktail of blood-thinning, skin-numbing, human-immune-system-fighting saliva. Then it’ll likely feed for about 2 to 3 days, and, if it’s a female, can swell up to nearly in double its normal size—which is useful for when it needs to lay eggs. They produce around 2000 eggs that are usually laid under the pile of leaves. Ticks can survive from 2 months to 2 years, depending on the species. Also, they can survive without food 200 days.

“It’s not like a mosquito, which stays on you for a few minutes,” says Peter Krause, MD, a senior research scientist in epidemiology and microbial diseases at the Yale School of Public Health.

Unlike many other biting pests, ticks are adapted to feed for long periods of time. They bury their curved teeth deeply into the skin of a host, so they can remain securely attached for days on end to eat. It’s important to note that ticks typically require 24-48 hours of feeding before they can successfully transmit infections. There about 850 tick species, some of which are capable of transmitting diseases such as Lyme disease, Ehrlichia, and Rocky Mountain spotted fever. The spinose ear tick has a worldwide distribution, the young feeding inside the ears of cattle and wild animals. Ticks of domestic animals cause considerable harm to livestock by transmission of many species of pathogen, as well as causing anaemia and damaging wool and hides.

Tick, Tick, Tick: Blood-Sucking Menace May Get Early Start

By RICK FOSTER, The Sun Chronicle

ATTLEBORO, Mass. (AP) — Ticks are normally thought of as a menace mostly in the warmer months when children, pets, and adults spend more time outdoors and bring home the hitchhiking insects.

But thanks to recent rain and snowfall together with a warmer February, they may be getting a head start this year.

“Warm weather tends to bring them out,” said Lauren Gordon, director of the Audubon Society’s Oak Knoll Wildlife Sanctuary, who added that she got a reminder of tick season recently when she had to remove one from her son. “We’re reminding hikers to take precautions and do tick checks to make sure they’re not taking ticks with them.”

While the deer tick is typically smaller than the dog tick, it’s difficult for most people to differentiate between the two. Experts recommend avoiding both types.

Lyme disease is on the rise in Ontario — here’s how to protect yourself
By Trevor Dunn, CBC News Posted: May 19, 2017

Officials are warning about Lyme disease with warmer weather and an increase in blacklegged ticks

Ontario public health officials are asking residents to watch out for ticks, the tiny arachnids that can spread Lyme disease.

Dr. Curtis Russell, a biologist with Public Health Ontario, told CBC Radio’s Metro Morning that the agency is tracking a “steady increase” in the number of cases of Lyme disease.

“We’re also seeing an increase in the number of blacklegged ticks, which is the only tick that can transmit Lyme disease in Ontario,” Russell said on Friday.

This shows that these small creatures can cause a huge nuisance. This menace needs to be stopped. Also, the solution to stop the nuisance caused by the midges has to effective and environment-friendly. You’ll find all sorts of tick removal suggestions on the Internet, according to a review in the British Medical Journal. People recommend rubbing petroleum jelly, gasoline, nail polish, or 70% isopropyl alcohol over the tick’s mouthparts, ostensibly to “suffocate” it. The problem is, say the researchers, none of these methods actually work—ticks can survive long periods without air. So trying these methods is of no use.

C Tech Corporation has a solution to tick menace.

We, at C Tech Corporation, have thought about this problem in detail and have come up with a viable solution. The solution is named as Termirepel™. We are the sole manufacturers of the product Termirepel™.

Our company believes in the principles of sustainability and eco-balance. We do not want to imbalance the cycle of life; therefore Termirepel™ can be easily described as insect aversive, used also against all types of insects.

Our product available in the form of masterbatch can be incorporated into the polymeric applications like the polymeric pet house, food containers used to store pet food, polymeric home appliances etc.

The product available in the form of liquid concentrate can be incorporated in the paints and can be used on the interior and exterior of the pet houses, pet shops, human houses, hospitals, schools etc.

The product available in the form of lacquer can be applied as a topical application and can be used on the already installed applications like furniture, fences, wires and cables, pipes etc. The lacquer is compatible with most of the surfaces like wood, polymer, metal, concrete, ceramic etc.

Pest with horns: Rhinoceros beetle

The name for these creatures come from the horns they possess.

But these horns are used for destroying the trees and to feed on their sap!

The rhinoceros beetle is a pest species occurring throughout many tropical regions of the world. Adults can cause extensive damage to economically important wild and plantation palms.

Although it is found in several regions of the world, its shape, size, and color are generally consistent. Adult beetles range from 1.2 to 2.5 inches in length and are dark brown or black. The ventral surface (underside) of males and females has reddish-brown hairs, but the female has a fuzzy grouping of these hairs at the tip of the abdomen. Both males and females possess a similarly sized horn used for leverage when moving within tightly-packed leaves or within the cavities, they create in the crown of palms, the horn length is longer on average for males.

Rhinoceros Beetles have two sets of wings and can fly. The outer set of wings protects the real working wings underneath. Because of the horns lightweight and hollow characteristics, it does not interfere with the beetle’s ability to fly.

The rhinoceros beetle’s diet consists mainly of rotting fruits, tree sap, and wood from decaying trees.

Locating them can be difficult due to the beetle’s nocturnal activity and residence within trees. Visual signs such as holes bored at the base of leaves and V-shaped feeding damage help locate this beetle.

Rhinoceros beetles are the strongest animals on the planet, proportionally. They can lift up to 850 times their own weight. To put this into perspective, if a human of average height and weight had the strength of the rhinoceros beetle, it would be able to lift a 65-ton object.

Rhinoceros Beetles can fly strongly and are attracted to lights at night. They are generally noticed when they come to house lights or when they are seen lying beneath street lights and on the concrete tarmacs of petrol stations.

The horns of the males are used for fighting—both over females and for feeding sites on trees, logs, and even crops. The horns are used not to inflict injury but rather to force rivals from the disputed area.

Rhinoceros beetle is mainly a pest of coconut and oil palms.

The beetles’ damage palms by boring into the centre of the crown, injuring the young growing tissues and feed on the exuded sap.

As they bore into the crown, they cut through the developing leaves. When the leaves grow out and unfold, the damage appears as V-shaped cuts in the fronds or holes through the midrib.

The nuisance caused by these pests is documented in the below news articles which informs that the commonly used pesticide does not work against them!

Navy battling rhino beetles infestation at Hawaii base

By WYATT OLSON | STARS AND STRIPES Published: October 9, 2014

FORT SHAFTER, Hawaii — There’s a war raging at Joint Base Pearl Harbor-Hickam, and the Navy is bringing in real firepower.

The enemy is an invasive insect from Southeast Asia called the coconut rhinoceros beetle, whose destructive munching on palm trees has the potential to disrupt coconut and date farming in Hawaii — and in California if the exotic pest is inadvertently carried to the mainland.

State agencies and the military have spent about $5 million this year to detect and eradicate the beetle, which can grow to 3 inches long and about half that width. The first beetle was discovered in December in a green space on the base that borders Honolulu International Airport.

The Navy’s share of the eradication expenses is about $2 million, according to Tom Clements, a Navy Region Hawaii spokesman.

Meet the beetles: Hawaii mobilizes to fight bug invasion

By Matt Smith, CNN

Updated 1614 GMT (0014 HKT) February 9, 2014

What’s Hawaii without palm trees?

That’s a question the island state hopes it won’t have to answer as it attempts to stave off an invasion by the coconut rhinoceros beetle, an unwanted visitor that’s already done extensive damage on the U.S. Pacific territory of Guam.

Big, hungry and hard to kill, the coconut rhino beetle bores into the tops of coconut palms, eating growing tissues, drinking the sap, ripping into the bases of fronds and exposing the plant to disease. Then it crawls off to breed, preferably in piles of mulch or trash. Adults can grow up to two inches long and live to the ripe old age of three months.

“This beetle is really tough, and most of the pesticides that are legal for use in Hawaii do not work on it,” said Darcy Oishi, the state Agriculture Department official in charge of containing the beetle.

In such a situation an effective method is needed which provides protection from the menace caused by the rhino beetle and hence C Tech Corporation has introduced an insect aversive named Termirepel^TM.
Termirepel^TM is an extremely low toxic, non-hazardous, non-mutagenic and non-carcinogenic anti-insect aversive.

Termirepel^TM is developed on green technology and chemistry. It is effective against a broad spectrum of insects such as rhino beetle, kudzu bugs, wasps, whiteflies, termites, beetles etc.

Our masterbatch is to be incorporated with polymers while processing them and can be used for producing tree guards, agricultural films, irrigation pipes, polymeric parts for agricultural utilities, etc.

Our liquid concentrate is to be mixed with paints in a proper ratio and can be applied on interior and exterior of houses, offices, schools, areas of mass transits etc. to prevent these pests from residing in these places.

The product available in the form of lacquer can be directly applied to the tree trunks. This will prevent these pests from attacking the trees. The lacquer is compatible with a variety of surfaces like wood, metal, polymer, ceramics, concrete etc.

Use our safe and eco-friendly products to keep the pests at a bay!

Armyworms – The crop destroyers!

The African crops are known to be damaged by these pesky pests known as armyworm.

Why do they attack the crops? How do they invade the farms?

These voracious armyworms are known to ravaging the crop fields.

Let’s have a look at how these pests can cause a nuisance.

Armyworms are nocturnal.

Armyworms feed on leaf tips and along leaf margins. When they eat whole leaves, they can remove them completely or leave only the midribs.

These pests give eggs which are creamy white and dome-shaped, with a flat base. The nuisance caused is by the caterpillar, the larval stage. When newly hatched, the larva is light green with a dark head capsule and measures approximately 1/16 inch long. As the larva feeds, it becomes darker and longer with light colored lines down the sides of its body. The head is unique in that it has a light yellow inverted “Y” on the top. As it matures, it also contains 4 black dots on the end of its abdomen. The fully grown larva is about 1½ inches long. This larva is an extreme nuisance that eats everything it possibly can.

The common armyworm is the more usual pest in spring and early summer. Adult armyworms survive better and produce more eggs when the temperature is at 15°C maximum, and when plants are naturally fertilized. Periods of drought followed by heavy rains and the presence of alternate hosts also sustain the development of armyworms.

The larvae usually feed in the upper portion of the rice canopy on cloudy days or at night; while the adult feeds, mates, and migrates at night and rest in the daytime at the base of the plant.

In dryland fields, armyworm pupa can be found in the soil or at the base of the rice plants. In wetlands, they pupate on the plants or on grassy areas along the field borders.

Since the fall armyworm moth is active very early in the morning and very late in the evening, it can be difficult to identify them. Fall armyworms develop shortly after an adult moth lays her eggs on or near a lawn, which also makes it difficult to prevent them. The moth will often choose areas near healthy, well-irrigated lawns on which to lay her eggs, making your grass the most desirable spot.

When the army worn attack, the pasture patches typically appear browned or burned out resembling drought damage. The damaged patch will increase in size over time, as fall armyworms chew more tender growth. Fall armyworms typically target newly established stands of bermudagrass, winter annuals, fescue, or orchardgrass.

Paddy across 4,000 hectares infested with armyworm

By Veerendra P.M. NOVEMBER 25, 2017 – The Hindu
77,000 hectares were used to grow the crop in Shivamogga

Mythimna Separata, popularly known as armyworm, has begun devouring the paddy crop in the district.

According to a preliminary estimate, paddy crop on more than 4,000 hectares in the district has been infested with armyworm. The worms hide under soil clods and in cracks along the bunds of paddy fields during the day. They are nocturnal and migrate from one field to another at night.

Shivamurthy, a farmer from Veerapura village in Bhadravathi taluk, told The Hindu that the pests were consuming the leaves and grains of the plant and leaving the stem behind. The intensity of the infestation in paddy fields in the command area of Bhadra reservoir is high. In many villages, the crop in the infected field was destroyed in one night.

Fall Armyworms Are Ravaging Crops in Many African Countries

Posted 29 June 2017 – Global Voices

As African economies begin to emerge from the global financial crisis of the last decade, a new threat to the agricultural sector in many countries may slow recovery: the invasion of the fall armyworm (Spodoptera frugiperda).

Originally from the Americas, the fall armyworm was first detected in west and central Africa at the beginning of 2016 (Sao Tome and Principe, Nigeria, Benin, and Togo). About a year later, it was found in Angola, Botswana, Kenya, Malawi, Mozambique, Namibia, Niger, Rwanda, Sierra Leone, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe. And the invasion isn’t showing signs of stopping anytime soon.

The caterpillar invasion has caused terrible damage in the affected countries. As a result, the Food and Agriculture Organization (FAO) convened an emergency meeting in Zimbabwe during which experts from 13 countries gathered to adopt a strategy for fighting this disaster.
