Rice is a necessary portion of diet for people all around the world. Also, it is one of the most produced plants in the world. Rice is grown in more than a hundred countries, with a total harvested area of approximately 158 million hectares, producing more than 700 million tons annually (470 million tons of milled rice). But this crop is under threat of a destructive pest called brown plant hopper.

The brown plant hoppers are small insects. The adults measure about 4-6 mm in length and 3-4 mm in width.

BPH are among the most important pests of rice, and rice is the major staple crop for about half the world’s population. They damage rice directly through feeding and by transmitting two viruses, rice ragged stunt virus and rice grassy stunt virus. Up to 60% yield loss is common in susceptible rice cultivars attacked by BPH. BPH prefers to feed on 45-50-day old plants.

The BPH are distributed in: Australia, Bangladesh, Bhutan, Burma (Myanmar), Cambodia, China, Fiji, India, Indonesia, Japan, North and South Korea, Laos, Malaysia, Nepal, Pakistan, Papua New Guinea, Philippines, Sri Lanka, Taiwan, Thailand, and Vietnam. 

Symptoms will not be visible from outside in the early stages, but if we enter the field and tap the plants’ large number of this insect can be seen. They are visible only when the damage has been severe, the plants present a burnt-up appearance.

Both the nymphs and adults remain at the ground level and suck the plant sap. It is a typical vascular feeder primarily sucking phloem sap leading to hopper burn.

At early infestation, circular yellow patches appear which soon turn brownish due to the drying up of the plants. The patches of infestation then may spread out and cover the entire field.

The grain setting is also affected to a great extent. During sustained feeding, it excretes a large amount of honeydew. It also acts as a vector of the virus diseases like a grassy stunt, wilted stunt, and ragged stunt.

News was reported in Odhisha TV that Brown Plant Hopper Attack: Farmers Gherao Agri Official In Sambalpur

By Odishatv Bureau On Oct 24, 2017 – Odhisha TV
Sambalpur: The increased worries of farmers over brown plant hopper (BPH) attack on the paddy and non-paddy crops in Sambalpur district took a different turn today with the farmers’ union today staging a demonstration outside the Deputy Director of Agriculture’s office here. The farmers gheraoed the district deputy director of agriculture by forcing him to sit down in an open space to apprise him of their problems along with measures to mitigate the issue.

Following the gherao, Sambalpur DDA Pradosh Samal shot a letter to the deputy director of agriculture, Bhubaneswar with detailed block-wise information on the BPH destruction in paddy and non-paddy crops. The letter addressed to Deputy Director of Agriculture, Bhubaneswar, stated that of the total 20 blocks in the district, 9 are badly affected by the pest. As many as 534 villages under 137 panchayats are affected due to the pest menace, the letter added.

Single variety paddy seeds reason for pest attacks in Odisha: AIKMS

BERHAMPUR, JANUARY 22, 2018 – The Hindu

According to experts, no seed variety is to be used continuously for more than a decade
Unscientific use of single variety of paddy seeds by farmers for more than a decade is the key reason behind the large-scale destruction of standing crops by pests like brown planthopper in Odisha, the All India Kisan Mazdoor Sabha (AIKMS) has said.

The organization came to the conclusion after conducting its own ground-level study. Through its practical experimentation, it has also proved that organic cultivation of traditional paddy seed breeds makes it immune to such pests in the State.

Brown Plant Hopper: A surgical strike that farmers in India’s granary were least prepared for

Written by Harish Damodaran | The Indian Express | Published: October 27, 2016

Hot and dry weather raises the chances of whitefly attacks, as Punjab’s farmers discovered for cotton last year. This year, it is humid and warm conditions, particularly in September, that has put paid to their hopes of a bumper paddy harvest. The villain: an innocuous-looking insect called the brown plant hopper (BPH).

Unlike most other pests, this one typically strikes very late, when the paddy crop is already 80-90 days old and in the final grain-filling stage. The female moths lay eggs from early-September that hatch within 10 days. The larvae emerging from them are the real baddies. These immature nymphs settle at the lower stem or culm of the paddy plant, from where they start sucking the sap. Since this sap rich in carbohydrates is transported through the phloem tissues to the grains that are still forming, it being sucked also impacts filling.

Traditionally many pesticides have been used to prevent the nuisance caused by these insects but all of them have proved ineffective. Now, we no longer should depend on these conventional, toxic insecticides to deal with these pests!

So, what to use to keep these pests away?

Termirepel^TM a C Tech Corporation product is best to deal with the nuisance caused by these pests.

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, RoHS3, REACH, ISO, APVMA, NEA compliant and FIFRA exempted.

Our Termirepel^TM masterbatch can be incorporated in the agricultural films, polymer mulches, green house 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.

Our lacquer product can be applied on already installed applications. The lacquer is compatible with most of the surfaces like metals, wood, polymers, concrete etc.

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.

Street trees keep the city cooler, reduce the runoff to the winter, and provide aesthetic benefits. We have to have trees in the city to make it a livable place.

The ash tree was thought to have medicinal and mystical properties and the wood was burned to ward off evil spirits. In Norse Viking mythology, ash was referred to as the ‘Tree of Life’. Even today it is sometimes known as the ‘Venus of the woods’. In Britain they regard ash as a healing tree. 

But in the recent times, this tree is under the threat of the emerald ash borer (EAB) beetle attack.

More than 60 million ash trees, ranging from one inch to five feet in diameter, have been killed by EAB in the southeast Michigan area alone and tens of millions throughout other states and Canada.

Once EAB populations begin to build, nearly all ash trees in the forest, swamp or urban area are likely to become infested and die — often within a time span of only a few years.

The EAB larvae bore into the ash tree and feed under the bark, leaving tracks visible underneath. The feeding disrupts the tree’s ability to transport water and nutrients, resulting in dieback and bark splitting.

Ash Borer Threat To Continue In Manitoba Despite The Cold

Written by Connor Gerbrandt │ February 28^th 2019

It looks like emerald ash borers will continue to be a problem in Manitoba, despite the extremely cold weather we had in Southern Manitoba.

Many people were hoping the twin polar vortexes that brought nearly a month of frigid weather would drive the invasive species extinct within the province. Unfortunately, Manitoba Sustainable Development says this will not be the case.

“What we do know is that the cold weather will kill some of the ash borers,” says Pest Management Biologist Fiona Ross “but we also know that it will not kill them all.”

According to Ross, recent in-lab testing shows that roughly 75% of the ash borers die at temperatures colder than minus 30. However, she acknowledges that in a real-world scenario that number is likely much lower.

Emerald ash borer has spread so much in NH that quarantines are no longer worth it

By  David Brooks | September 4, 2018 

Five years after the invasive insect known as the emerald ash borer was first spotted in Concord, it has spread so far throughout the state that officials may end the quarantine which tried to contain it.

The move would not be a surprise since scores of other states have tried and failed to stop the spread of the beetle known as EAB, which can fly five miles or more at a time.

Insecticides and some biological control practices are being implemented but these have proved to be ineffective.

We need a solution that is effective, eco- friendly and easy to use.

C Tech Corporation can provide you with one such effective solution.The unique product Termirepel™ manufactured by C Tech Corporation is an anti-insect aversive which repels insects.

Termirepel™ 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™ is an extremely low concern, low toxic, low hazard, non-carcinogenic and non-mutagenic insect aversive. It does not kill or cause harm to insects as well as to the environment which indirectly helps to maintain the ecological balance.

Barely visible to the naked eye, the insect and its egg sacs are covered with a waxy, white ‘wool’. The sacs, most prominent in late spring, look like the tips of small cotton swabs clinging to the base of hemlock needles. An adult individual body length is typically 0.8 mm and is oval in shape. The tiny brown-colored insect has four thread-like stylets that are bundled together and function as a mouthpart.

A tree infested with the hemlock wooly adelgid can die within a few years. This serious pest has destroyed thousands of acres of trees.

The hemlock woolly adelgid feeds on the sap at the base of the host tree’s needles. This disrupts the flow of nutrients, slows the growth and causes the tree’s dark green needles to discolor and turn grayish green, eventually falling off. Lack of nutrients causes the tree to starve to death, usually within three to ten years.  It is quickest in areas where there are other pests, diseases or environmental stressors present.

The Hemlock Woolly Adelgid lives and feeds on hemlock trees, the eastern hemlock and Carolina hemlock neither of which are evolved to resist the pest. After the eggs hatch, the nymphs, or crawlers, move to the new needles of the tree and attach to the base of the needles to feed on the starch reserves and nutrients. This causes the needles to desiccate, dry up and prevents the growth of buds. The dead needles fall off, and the decrease of buds prevents new growth. 

The hemlocks could also be reacting to the infestation by producing abnormal xylem, which could obstruct water movement and lead to the death of the tree because of water stress.

Insect in hemlock forests causes loss of canopy, gain of invasive plants

By Sarah Yang, Media Relations | 26 May 2009 -UC Berkley News

BERKELEY — Deep in the hemlock forests of the Eastern United States, a tiny, aphid-like insect may be playing a giant role in transforming an ecosystem, according to new research by ecologists at the University of California, Berkeley.

It’s been well-documented that the spread of the hemlock woolly adelgid, an exotic pest native to Asia and introduced to the Eastern United States in the 1950s, has led to a decline of the shade-providing canopy in forests of eastern hemlock trees. The insect (Adelges tsugae) sucks fluid from the base of hemlock needles, causing the needles to drop and the branches to die

The new study has found that this loss of canopy is also setting the stage for the successful invasion of non-native plants. The canopy decline leads to even greater invasion of non-native plants when combined with a high concentration of the plants’ seeds and white-tailed deer in the affected area.

Hemlock die-off having major impact in Smokies

By Morgan Simmons of the Knoxville News Sentinel July 11, 2016

TOWNSEND — On a recent summer afternoon, the Anthony Creek Trail at the west end of the Great Smoky Mountains National Park presented stark contrasts between sunlight and shadow.

Much of the trail was shaded beneath the branches, but in patches of forest where the hemlocks had died, the ground was bathed in bright light. Beneath these gaps in the canopy grew various sun-loving species like blackberry and wild grape. High winds had pruned the dead hemlocks of their limbs and their tops, and the trees still standing looked ready to fall, too.

Forests throughout the Smokies are undergoing a major ecological shift due to the hemlock die-off caused by the hemlock woolly adelgid, a nonnative forest insect pest that was discovered in the park in 2002. Trees that for years have suffered in a state of decline are now dead and toppling to the ground, creating a void that forestry experts say will affect everything from stream temperatures to forest composition.

Hemlocks are considered a “keystone” species, meaning that they play a critical ecological role. The dense shade provided by their branches keeps the soil underneath from drying out, creates cool habitat during the summer for plants and foraging animals, and protects the same areas during the winter from snow and wind, again providing habitat and food. 

Control measures for forest trees are limited. Also, the used control measures are ineffective, but the damage is still on.

How to deal with this?

C Tech Corporation can offer an eco-friendly solution to problems from Hemlock Woolly Adelgid. Our product Termirepel^TM is extremely low-toxic, low-hazard and insect aversive. 

Termirepel^TM is available in lacquer form. These products can be directly applied to the application as a topical application. It can be applied on the tree trunks to keep the trees safe from Hemlock Woolly Adelgid. The lacquer is compatible with most of the surfaces like wood, metal, concrete, polymers, ceramics, etc

Our Termirepel^TM masterbatch can be incorporated with various polymeric applications like tree guards, pipes, wires and cables, agricultural and other protective films, etc. while they are manufactured. This will prevent the pests from damaging the polymeric application.

Termirepel^TM is available in liquid concentrate can be mixed in paints and be applied to interior and exterior of houses, offices, kitchens, pantries, warehouses, bathrooms, attics, etc. It can be applied on the fences around the gardens, lawns, farms, etc.

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.

As a homeowner, you will discover over time that you share your living space with a variety of creepy crawlies, both small and tiny. One of the places in your home which provides shelter for these types of pests is your carpet and rugs.

Although carpet beetles are not dangerous to humans, they are definitely harmful to your belongings.

They will destroy your carpets from the bottom up. If your couch or chair is padded or cushioned, they can chew the covering to pieces. They will also create holes in clothing. They’ll damage rugs and wool clothing, as well as dirty clothing made of other fibers, such as cotton or silk. They’ll feed on skin cells, pet food, and can also get into packaged foods. Any box of undisturbed clothing or blankets is also a target for a carpet beetle.

Carpet beetle larvae are not extroverted creatures and will spend most of their time well-hidden, making it harder to identify them. Carpet beetle larvae feed primarily on animal products but will eat other items as well.

Once a home is invaded the adult female beetles can lay up to 100 eggs, which hatch into larvae in one to two weeks. 

Carpet beetles are spring’s uninvited guests

Les Harrison, Guest columnist Published March 28, 2019

Unfortunately, there are some species in residence which have awakened with a destructive appetite capable of taking the joy out from this time of year. Carpet beetles are active and seeking new territory to conquer.

Beware of carpet beetles

By Peter L. Warren │ September 14, 2015

They can be found on a variety of things besides carpets and are most likely infesting something near where you are seeing them in the pantry. These insects are sometimes used by mammalogists to clean animal skeletons in scientific collections. Sadly, they are also a serious museum pest and are notorious for eating insect collections and other dead animals.

Fumigation is done by homeowners and naphthalene balls are used without any instructions. Both these methods are extremely harmful to humans and pets.
