of estimating gypsy moth (Lepidoptera: Lymantriidae) egg mass densities. Journal of Economic Entomology Objective: To compare the timed-walk method of estimating egg mass densities of L. dispar against estimates in fixed-radius plots. Abstract: Gypsy moth, Lymantria dispar (L.) is an important defoliator of numerous hardwoods. The gypsy moth, native to Europe and Asia, is a major invasive pest of hardwood forests in the U. S. Introduced into Massachusetts in , the gypsy moth has rapidly moved into other regions of the country and is responsible for large amounts of defoliation each year. Most of Virginia is generally infested by this pest.
If the gypsy moth is allowed to spread, the cost of control to our state will increase by many millions of dollars. Many states with permanent populations of gypsy moth spray 1, times more pesticide in a single year to suppress gypsy moth than Washington does to eradicate it. Fast-growing gypsy moth caterpillars defoliate forest trees by eating leaves day after day. In early summer, the caterpillars can become a serious nuisance in yards by crawling everywhere and dropping unexpectedly from tree branches. Trees that are weakened year after year from gypsy moths can die from the repeated stress.

One of the great mysteries of gypsy moth (GM) in eastern North America is the origin of the fungus Entomophaga maimaiga, now the dominant natural enemy of fungus is in the order Entomophthorales, which are mostly insect pathogens, and “maimaiga” is the Japanese word for “gypsy moth.”.

Economic impacts affect all forest users. Caterpillars may chew small holes in leaves or completely strip a canopy, depending on age and population levels.
How to Identify Gypsy Moth. Four development stages: egg, caterpillar, pupa. Gypsy Moth. Summer - DEC has received reports of elevated populations of gypsy moth that are causing noticeable defoliation in Central and Western NY this year.

It was introduced for gypsy moth control many. Since early in the 19th century, ground and aerial applications of chemical pesticides, including DDT and other agents have been used for population control of gypsy moth (GM).

In the eastern US, the gypsy moth prefers oaks, aspen, apple, sweetgum, speckled alder, basswood, gray, paper birch, poplar, willow, and hawthorns, amongst other gypsy moth avoids ash trees, tulip-tree, cucumber tree, American sycamore, butternut, black.
Gypsy moths spread easily, as the young larvae can be carried by wind currents for a distance of up to one kilometre. More commonly, however, they hitch a ride (mainly egg masses) on objects like vehicles, tents, trailers, and lawn chairs to infest new areas.
Once gypsy moths become permanently established, it may take several more years for moth populations to build before residents see any noticeable defoliation. The first outbreak may last three to 15 years depending on weather patterns, local site conditions, and the presence of natural enemies.Female gypsy moths use chemicals to attract a mate soon after they emerge.
They lay eggs about a day after mating. Adult gypsy moth males have feathery antennae and brown wings and are able to fly, while cream-colored females of European gypsy moths cannot fly and have threadlike antennae. If it's a white moth and flying, it is not a Gypsy Moth. Gypsy moth numbers spiked in southern New England inafter nearly two years of drought paved the way for one of the worst outbreaks since the .
