Gypsy Moths Are Making A Comeback in Vermont. Why? (Jun 7, 2021)

Vermont Agency of Agriculture, Food, and Markets.

Many people in Vermont are encountering gypsy moths (GM) for the first time. This invasive species arrived in the United States over 100 years ago and has been expanding its range ever since. They can be significant defoliators (leaf eaters) of trees and shrubs. They prefer oak trees, but when there are a lot of caterpillars around they will eat any type of leaf, including maple and pine. Vermont has not seen an outbreak of GM since 1991. At that time a fungus called Entomophaga maimaiga became prevalent in the area and significantly decreased the GM population. But the dry weather that we’ve experienced over the last few years has not been good for fungi, and the absence of fungi has allowed the GM numbers to increase.

Historical Gypsy Moth Publications

USDA. ARS. National Agricultural Library.

This collection of publications in NAL's Digital Repository provides access to and addresses a number of topics concerning the gypsy and the related brown-tail moths, from biological control methods to tree banding to quarantine practices. The bulk of the documents were published from 1891 to 1923 by various agencies in the area of the initial infestation, including the State Board of Agriculture for Massachusetts, New York, and Rhode Island, but also include some more modern USDA publications.

Hungry Pests - Pest Tracker

USDA. Animal and Plant Health Inspection Service.

See what states have a federal quarantine for any of the targeted Hungry Pests, and identify which pests or diseases are at greatest risk due to a suitable habitat. In addition to federal quarantines, state-level quarantines might apply see State Summaries of Plant Protection Laws and Regulations (National Plant Board).

Invasive Forest Insects - Lymantria dispar dispar

USDA. FS. Forest Health Protection.

The USDA program to manage Lymantria dispar is a partnership with the Forest Service, APHIS, and state partners, to suppress outbreaks in the generally infested area, eradicate isolated infestations in the uninfested area, and slow the spread along the advancing front.
See also: The Lymantria dispar Digest for a database containing information about gypsy moth defoliation and treatments at the national level. Treatments include those funded by the Suppression, Eradication, and Slow The Spread (STS) programs.
