Abstract
Grapholita molesta (Busck) (Lepidoptera: Tortricidae) is a notorious pest of many Rosaceae crops worldwide. Enhancement of trap efficiency of its sex pheromone was devised by addition of E-β-ocimene and E-β-farnesene. The addition of E-β-ocimene or E-β-farnesene to sex pheromone increased electroantennogram response of male G. molesta compared to sex pheromone alone. Blend of pheromone and E-β-ocimene or E-β-farnesene in 1:0.1 increased the upwind flight and landing behaviors. Furthermore, field experiments showed that sex lures with E-β-ocimene, or /and E-β-farnesene, enhanced trapping efficiency compared to sex pheromone alone. These results may provide the basis for the development of efficient pest management systems against G. molesta using plant volatiles and insect sex pheromones.
