ATTRACTION OF MATED FEMALE CODLING MOTHS (LEPIDOPTERA: TORTRICIDAE) TO APPLES AND APPLE ODOR IN A FLIGHT TUNNEL

Abstract

Abstract In a flight tunnel, mated female codling moths, Cydia pomonella L., were attracted (upwind flight with zigzagging flight patterns) to cold-stored thinning apples. Greater numbers of codling moths were attracted to apples infested with codling moth larvae than to uninfested apples. However, codling moth response to piped odor from cold-stored thinning apples infested with larvae was not significantly greater than that of moths to piped odor from uninfested apples. In a flight tunnel, significant numbers of mated female codling moths were captured in traps baited with fresh-picked immature apples or in traps through which odor from such apples was piped. Also, more codling moths were captured in traps baited with infested versus un-infested apples, and more were captured in traps with odor from infested apples compared to odor from un-infested apples. These studies demonstrate upwind attraction by flying female codling moths to apple fruit and odors from apple fruit and show increased response by m...
