Unusual acetylenic sex pheromone of grape leaffolder (Lepidoptera: Pyralidae).
The female-produced sex pheromone of grape leaffolder, Desmia_funeralis (Hübner), has been identified as a blend of (Z,Z)-11,13-hexadecadienal, 11-hexadecynal, and (Z)-11-hexadecenal. The first two components were essential for attraction of male moths, whereas the third compound was not essential, but increased trap catches approximately twofold when added in appropriate doses to the optimum blend of the other two components. In field tests, male moths were trapped equally well in traps baited with pheromone doses of 0.2 to >6 mg, and lures remained attractive for at least 5 wk.
