Introduction
The Asian Gypsy Moth (“AGM”, including Lymantria dispar asiatica, Lymantria dispar japonica, Lymantria albescens, Lymantria umbrosa, Lymantria postalba) is a highly destructive forest pest that feeds on both deciduous and coniferous trees.
The voracious appetite of AGM larvae (caterpillars) coupled with the ability of the female moth to travel significant distances (as much as 20 nautical miles) can cause widespread defoliation leaving trees weakened and susceptible to disease and other pests.
AGM is found primarily in Asia or Russia with a high risk of AGM egg infestation of vessels calling at ports in Korea, Northern China (north of Shanghai; ports north of latitude 31˚15’N), and in particular the Russian Far East and Japan during the flight season of the female moth.
