Lymantria dispar

gypsy moth

These larvae cause wide-spread defoliation of trees, especially oak, and other plants. Spray with bacillus thuringiensis var. kurstaki when leaves are starting to open, repeat in 7 days. Find and destroy egg masses and pupae, using vegetable oil sprays. Using various sticky compounds such as Tanglefoot on bark of trees can prevent them from reaching the fruit. Pheromone-based traps may be quite effective. Spined soldier bugs, Podisus maculiventris, are available commercially, as are lures for them.
