Potential of ethyl (2E,4Z)-2,4-decadienoate for monitoring activity of codling moth (Lépidoptèra: Tortricidae) in eastern North American apple orchards

摘要

In Ontario apple orchards, the amount of synthetic codling moth (Cydia pomonella (L., 1758)) sex pheromone, E,E-8,10-dodecadien-l-ol (0.01-10.0 mg) used to bait traps significantly affected the mean total numbers of moths captured, whereas similar mean total numbers of moths were captured in traps baited with different amounts of pear-derived kairomone, ethyl (2E,4Z)-2,4-decadienoate (0.01-10.0 mg). The attractiveness of kairomone-baited traps was not increased by using greater amounts (100 and 1000mg) of this compound. The attractiveness of the pheromone was not enhanced by the addition of kairomone. Similar patterns of adult male seasonal activity were observed when using pheromone-baited traps and kairomone-baited traps. The potential usefulnessof kairomone-baited traps in the integrated management of C. pomonella in Ontario apple orchards is discussed.
