The Alien Forest Pest Explorer (AFPE) is an interactive web tool which provides detailed spatial data describing pest distributions and host inventory estimates for damaging, non-indigenous forest insect and disease pathogens currently established in the U.S. The database is maintained as a joint effort of Purdue University, the U.S. Forest Service Northern Research Station, and the U.S. Forest Service Forest Health Protection.

Provides state, county, point and GIS data. Maps can be downloaded and shared.

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.

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.

Forest pest first detectors are trained to quickly detect and diagnose early infestations of emerald ash borer, spongy moth, Asian longhorned beetle, Japanese barberry, Oriental bittersweet and other pests, so that state and federal agencies can control the spread. Become part of the award-winning Minnesota Forest Pest First Detector volunteer program to help the public find new invasive species affecting Minnesota’s trees and forests, or attend as a refresher for those already active as Forest Pest First Detectors.

The National Slow the Spread (STS) Program is dedicated to slowing the spread of spongy moth (Lymantria dispar) throughout the U.S. The STS Program is part of the USDA's  integrated pest management (IPM) program and national strategy for Lymantria dispar management. Slow the Spread efforts are coordinated by a chartered, non-profit foundation that coordinates the operations of the program and facilitates the movement of funding between federal (USDA Forest Service and APHIS) and state agencies. Slow the Spread is one of the world’s largest and most successful integrated pest management programs. 

State and Federal agencies collaborate in a national integrated pest management (IPM) program called the Slow the Spread Program (STS) to reduce the spread rate of Lymantria dispar and limit its impacts. Slow the Spread is one of the world’s largest and most successful integrated pest management programs.

The spongy moth, (Lymantria dispar), formerly known as the "gypsy moth," continues to spread throughout North America, threatening deciduous trees and impacting humans. This non-native, foliage-feeding insect currently occupies only about one-third of its possible host distribution in the United States. Efforts to reduce its impact and spread represent one of the largest and most successful federal and state agency integrated pest management programs against a forest pest.

This new General Technical Report (GTR), published by the Northern Research Station, synthesizes information about the Slow the Spread Program, its accomplishments, and provides a framework for future landscape-level integrated pest management.

Help the United States Department of Agriculture (USDA) stomp out invasive pests this spring! Challenge your detection prowess: Look for spotted lanternfly and spongy moth egg masses on vehicles, trees, and other outdoor surfaces during the winter and early spring.

Emerald ash borer, laurel wilt disease, thousand cankers disease, and the European gypsy moth are likely to be brought into North Carolina in or on firewood. The use of local firewood is an important factor in preventing the spread of potentially devastating invasive species to our state's forests. Please keep this in mind as you prepare for your outdoor recreation activities. See Forest Health Invasive Pest Maps for more information about pest monitoring.
