After an absence of widespread gypsy moth outbreaks in recent years, the bugs are back.

Spring foliage in some parts of Pennsylvania could be despoiled this year by an unusually large infestation of gypsy moths. The state Bureau of Forestry and the Pennsylvania Game Commission have launched simultaneous eradication programs at locations across the commonwealth.

The Department of Conservation and Natural Resources plans to spray 221,831 acres in 27 counties. And the Game Commission has scheduled the spraying of 42,731 additional acres in 38 state game lands.

"As we anticipate more gypsy moths, it's very important to remember spraying is designed to protect trees in forested landscapes from moderate to severe defoliation," said DCNR secretary Michael DiBerardinis. "We can't eradicate an insect that's well established in Pennsylvania and is here to stay."

Spraying on state game lands during turkey hunting season could disrupt hunts, but Game Commission officials say the insecticide is not harmful to humans.

"Those participating in spring gobbler seasons may encounter helicopters or other aircraft spraying state game lands or other forested areas," said William Capouillez, director of the commission's Bureau of Wildlife Habitat Management. "We want those hunters to rest assured that the spray being used is not harmful to humans, and only will impact gypsy moth caterpillars when they ingest the spray."

Growing Greener II funding will supply the $1,349,993 needed by DCNR to pay for the joint Statewide Cooperative Spray program.

Last year, says DCNR, 64,900 acres of private, state and federal woodlands were sprayed to control gypsy moths, but the caterpillars defoliated 681,000 acres.
