Abstract:

The responses of tufted apple bud moth, Platynota idaeusalis (Walker), the leafroller P. flavedana Clemens, redbanded leafroller, Argyrotaenia velutinana (Walker), and obliquebanded leafroller, Choristoneura rosaceana (Harris), to the pheromone blends of each, as well as to 3 putative generic blends (two- and three-component blends containing pheromone elements of each of the 4 species) were evaluated in small orchard plots. P. idaeusalis and P. flavedana, and A. velutinana and C. rosaceana comprise 2 pairs of species, each pair with broad overlap in pheromone blend, and quite different from one another. Each generic blend suppressed trap captures of all 4 species. The blends for P. idaeusalis and P. flavedana each reduced captures for these species. Furthermore, the blend for P. idaeusalis also suppressed captures of A. velutinana. The P. flavedana blend did not reduce captures of A. velutinana; in fact, at times captures increased. This study determines relative abilities of several sex attractant blends to reduce captures of 4 leafroller species in pheromone traps, presumably reflecting the ability of a blend to reduce orientation of males to females in a large block situation. This is a requisite 1st step in the development of a multispecies mating disruption blend.
