An Urban Forest Integrated Pest Management Program for Gyspy Moth: An Example    (View PDF)

Mark Ticehurst and Stuart Finley

Abstract: An integrated pest management program for gypsy moth was designed, implemented, and evaluated in the urban forested community of Lake Barcroft, Falls Church, VA. The objectives of the program were to reduce or prevent defoliation, tree mortality, and nuisance associated with dense populations of gypsy moth. Intensive surveys of larvae, pupae, adult males, and egg masses were evaluated in 100 sites. Further evaluations were made of eggs per mass, egg viability, parasitism of eggs, larvae, and pupae, sex ratio of pupae, and tree susceptibility to infestation and defoliation. Bacillus thuringiensis and LuretapeŽ were selectively applied. The larval parasites, Cotesia melanoscelus and Glyptapanteles flavicoxis were released throughout the Program area. The objectives were achieved. The cost was approximately $20. per residential lot per year.
