EVIDENCE FOR A FEMALE-PRODUCED SEX PHEROMONE IN THE APPLE LEAF MIDGE, DASINEURA MALI (KIEFFER) (DIPTERA: CECIDOMYIIDAE)

The apple leaf midge, Dasineura mali (Kieffer), is an apple pest in Nova Scotia's Annapolis Valley (Rogers 1991). Larval D. mali are specialist, leaf-feeding pests that attack primarily young pubescent apple shoots. Larval feeding induces the leaves to curl tightly toward the midrib and form distinctive reddish galls that desiccate following larval exit. Economic damage to orchards in Annapolis Valley has not been estimated, but immature trees and nursery stock are vulnerable because new growth is essential for proper tree formation (Rogers 1991).
