Abstract
The effect of the major component of codling moth, Cydia pomonella (L.) ) sex pheromone (codlemone, E,E-8,10-dodecadien-1-ol) on female calling and oviposition behavior was investigated. Calling by virgin females was similar between moths placed in sealed containers containing codlemone or codlemone-free air. However, when pheromone emitted by females was removed by a continuous air stream, calling in codlemone-permeated air was significantly higher than in clean air. The temporal pattern of calling was unaltered by the presence of codlemone. In a laboratory no-choice test, oviposition rates by codling moth females were similar in the presence of codlemone and in codlemone-free air. However, in paired-choice tests, females deposited more eggs on uncontaminated waxed paper surfaces than on codlemone-contaminated surfaces.
