The defoliator moth – Gypsy moth

The tiny critters with hairy bodies feast on leaves and wreak havoc on trees.

Those are the gypsy moths who cause this nuisance.

Gypsy moth caterpillars are easy to identify because they possess characteristics not found on other leaf-feeding caterpillars. They have five pairs of blue dots followed by six pairs of red dots lining the back.

The moth (the adult stage) is usually present in July and August. The male moths are brown and tend to fly in zigzag patterns. The female moths are white or cream colored and do not fly at all. The female lays her eggs in masses, usually on branches and trunks of trees. Egg masses can also be found on patio furniture, recreational vehicles, and other outdoor items. The egg masses are cream or buff in color and about an inch or so in length.  The eggs inside is black and palletlike. Each mass may contain 400-600 eggs.

They are responsible for causing mortality of susceptible host trees. Gypsy moth caterpillars prefer hardwood trees and are known to feed on more than 300 tree species including, but not limited to oak, apple, some poplars, willow, alder, and hawthorn.  The caterpillars are defoliators; they eat the leaves of the host trees. Young caterpillars eat small holes in the middle of the leaves, while older caterpillars feed on the outer edge of the leaf inward. Heavy defoliation by the larval stage of this pest causes stress to the infested host plants. Gypsy moths defoliate millions of acres of trees in the United States yearly; repeated infestations weaken and kill the trees.

The nuisance caused by the gypsy moth is spreading vastly and the evidence for it is here!

WOODWAY, Wash. (AP) — Washington state officials have scheduled an aerial drop of insecticide to stop an invasive moth and to prevent forest foliage damage.

The Daily Herald reported that the state Department of Agriculture announced about 2 square miles in Woodway and in an Everett neighborhood will be sprayed with more than 655 gallons of soil bacteria.

Department spokesperson Karla Salp says the treatment is scheduled for Friday, depending on weather conditions.

Pest control methods have been used to stop the menace the caused by these insects. But those methods did not work to stop the nuisance.

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

The unique product TermirepelTM manufactured by C Tech Corporation is an insect aversive repellent which repels insects.

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 to the applications.

To keep the insects at the bay TermirepelTM lacquer can be sprayed or coated on the tree trunks. The already installed tree guards can be coated with the lacquer.

TermirepelTM is available in the form of the masterbatch, which can be incorporated with the polymeric applications like tree guards, irrigation pipes, agricultural films, wires and cables etc. to keep the gypsy moth away. The polymeric tree guard can be manufactured incorporating our masterbatch into the applications while they are manufactured.

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 scale insects and other insects that could damage the trees. Thus, using TermirepelTM would effectively ensure that the area around us remain safe and protected from the pests for a long period of time.
