The gypsy moth is the most destructive forest insect pest to infest New Jersey's forests. Repeated defoliation by the gypsy moth represents a serious threat to New Jersey woodland and shade tree resources.
The New Jersey Department of Agriculture promotes an integrated pest management approach, which encourages natural controls to reduce gypsy moth feeding and subsequent tree loss. However, when gypsy moth cycles are at a peak, natural controls have difficulty in preventing severe defoliation. In these special cases, the Department recommends aerial spray treatments on residential and recreational areas using the selective, non-chemical insecticide, Bacillus thuringiensis. The Department's Gypsy Moth Suppression Program is a voluntary cooperative program involving New Jersey municipalities, county agencies, state agencies, and the USDA Forest Service. In order to protect New Jersey's valuable forest resources, the Department conducts aerial defoliation and ground egg mass surveys, monitors the application and evaluates the efficacy of the spray material.
