Abstract

The sex pheromones of Archips argyrospilus (Walker), Archips rosanus (L.), Choristoneura rosaceana Harris, and Pandemis limitata Rob. were evaluated in orchards with the objective of developing a method of monitoring leafroller population densities. The sex pheromones were specific for three species but not for C. rosaceana. This leafroller was captured in traps containing A. rosanus sex pheromone more frequently than in traps with its own attractant. The trapping program indicated that C. rosaceana and P. limitata were abundant in the southern fruit growing region of British Columbia and that A. argyrospilus and A. rosanus were the predominant species in the northern region. The traps can be used to identify leafroller species in orchards and to indicate when moths are active which may help in timing control measures.
