Secondary Sex Pheromone Components of Choristoneura murinana Hb.(Lepidoptera Tortricidae)

Abstract

The alkenyl acetates E9-12:Ac, ∆ll-12:Ac and Zll-14:Ac were identified as minor components of the C. murinana female pheromone blend by chemical analyses of volatile pheromone gland constituents and potential pheromone precursors, electrophysiological recordings from single receptor cells, and field trapping tests. Gland washes from virgin females contained these compounds at 3%, 10% and 5%. respectively, the amount of the primary pheromone component Z9-12:Ac already reported. A 0.3% addition of either ∆ll - 12: Ac or Zll-14:Ac significantly raised trap captures over Z9-12:Ac alone and a 3-30% addition of either minor component revealed maximum captures, not increased further by including both synergists within the same blend. A functional role of the £9-12: Ac could not be established during this study; 3% of it when combined with the pheromonal ratio mixture of the three other components tended to increase trap captures further whereas in various other mixture combinations the E9-12:Ac strongly reduced captures. These inhibitory effects were more pronounced with attractant blends based on Zll-14:Ac rather than ∆ll-12:Ac. Each blend component activated its owntype of antennal receptor cell.
