Evidence of an Attractant for the Click Beetle, Melanotus depressus , in the Pheromones of Two Platynota spp. (Lepidoptera: Tortricidae) 1

Abstract

Pheromone traps for 11 tortricid species were monitored in apple orchards throughout the Hudson and Champlain Valleys of New York. A click beetle, Melanotus depressus (Melshiemer), was found in the traps for the tufted apple budmoth, Platynota idaeusalis Walker, and the variegated leafroller, Platynota flavedana Clemens, but not in those of the other 9 species. Trap counts indicated beetle activity peaked in late May and again in late July at most locations. ( E )-11-tetradecenyl acetate and ( E )-11-tetradecen-1-ol were the Tufted apple budmoth pheromone components, while ( E )-11-tetradecen-1-ol and ( Z )-11-tetradecen-1-ol were the variegated leafroller pheromone components, which resulted in M. depressus attraction.
