The state DEC will be conducting aerial treatments for the invasive pest spongy moth (formerly known as gypsy moth) in six high priority forests in New York, including in Allegany State Park.

Treatment will take place through May 31, weather permitting. The priority areas chosen already suffered spongy moth defoliation for multiple years and are expected to have another high level of infestation this year according to survey efforts conducted by DEC regional staff.

“New York’s forest ecosystems provide critical habitat for a wide array of species while also providing a place for people to live and play.” said Basil Seggos, DEC commissioner. “These treatments, developed using sound science, will help DEC protect some of New York’s most vulnerable forests from the invasive pest spongy moth, which has been defoliating trees all across New York State for multiple years.”

The treatment being used is Gypchek, a biopesticide produced from a naturally occurring nucleopolyhedrosis virus, or NPV, that only affects spongy moth larvae. According to research by the U.S. Forest Service, Gypchek is not related to any human or mammalian viruses and is only distantly related to other insect viruses, therefore it has no negative effect on wildlife, plants, or people.
