title: Identification of the sex pheromone of Isoceras sibirica Alpheraky (Lepidoptera, Cossidae).
abstract: We discovered that extracts of the female sex pheromone gland of the carpenterworm moth Isoceras sibirica Alpheraky, a pest of Asparagus officinalis Linn., contained (Z)-7-tetradecen-1-ol (Z7-14:OH), (Z)-9-tetradecen-1-ol (Z9-14:OH), (Z)-7-tetradecenyl acetate (Z7-14:Ac), (Z)-9-tetradecenyl acetate (Z9-14:Ac), and (Z)-9-hexadecadecenyl acetate (Z9-16:Ac). The average levels of the chemicals in a single sex pheromone gland of a calling moth were (0.71 +/- 0.24) ng, (1.42 +/- 0.44) ng, (4.36 +/- 0.32) ng, (8.71 +/- 0.26) ng, and (0.82 +/- 0.38) ng, respectively. The electroantennography (EAG) analysis of these chemicals and their analogues demonstrated that Z9-14:Ac triggered significantly the male EAG response. Traps with rubber septa lure impregnated with Z9-14:Ac (500 microg/septum), Z7-14:Ac (250 microg/septum), and Z9-16:Ac (50 microg/septum) were more effective in catching male moths than traps with other baits or virgin females. Addition of Z7-14:OH and Z9-14:OH to rubber septa did not enhance the efficiency of the trap.
