This presentation by Tim Barwise (MA-DCR) the 2018 Vermont Maple Conferences covers the current infestation and the USDA-APHIS response to asian longhorned beetle (Anoplophora glabripennis) in the greater Worcester, MA area.
The Asian longhorned beetle, Anoplophora glabripennis (Motschulsky), threatens urban and forest hardwood trees both where introduced and in parts of its native range. Native to Asia, this beetle has hitchhiked several times in infested wood packaging used in international trade, and has established breeding populations in five U.S. states, Canada, and at least 11 countries in Europe. It has a broad host range for a cerambycid that attacks living trees, but in the introduced ranges it prefers maples. Identification, classification, and life history of this insect are reviewed here. Eradication is the goal where it has been introduced, which requires detection of infested trees using several approaches, including ground and tree-climbing surveys. Several agencies and researchers in the United States and Europe are evaluating the use of pheromone- and kairomone-baited traps. Control options beyond cutting down infested trees are limited.
This pictorial guide provides basic information for identifying the Asian longhorned beetle, its injury characteristics, and its common host trees. The guide will help users detect the beetle in both urban and forested settings.
Some maple producers have reported low sugar maple regeneration that could be related to the presence of worms. This second wave of invasion by Asian earthworms is of concern to forest ecologists because of its potential disruption to the forest.
The purpose of this website is to provide images and information of insects, diseases, weeds, and abiotic factors that cause damage to urban, managed, and natural forests. This site aggregates pictures, publications, and tools from many sources and packages the resources in an easy, searchable format. This site is intended to be used by homeowners, land managers, volunteers, urban foresters, county agents, outreach educators, and anyone else interested in identifying and managing their trees and forests.
The sugar maple borer, Glycobius speciosus (Say), a long-horned wood boring beetle, is a common pest of sugar maple (the only known host) throughout the range of the tree. Although borer-caused mortality is rare, infestations lead to value loss through lumber defect caused by larval galleries, discoloration, decay, and twisted grain.
Both the Asian longhorned beetle and the use of imidacloprid to protect sugar maples from this pest pose a threat to maple syrup producers.
Invasive exotic plants are becoming more prevalent and can have a negative impact on sugarbushes. Maple producers need to know how to identify and eradicate invasives.
We found significant populations of snake worms devouring the organic matter, causing soil conditions that discouraged growth of understory native plant species. We are looking at their distribution in maple stands throughout the region relative to forest management practices, and assessing their impact on understory diversity, maple regeneration and various soil characteristics.
