Abstract

Traps baited with pear ester + acetic acid were capable of monitoring the codling moth although caught fewer specimens than pheromone baited traps. The general flight patterns recorded in pear ester + acetic acid baited traps resembled closely those recorded with pheromone traps. The only aspect in which pear ester + acetic acid baited traps lagged behind was early detection of first moth specimens occurring in the season. The great advantage of traps with pear ester + acetic acid over pheromone traps was that the former caught females in a high percentage. Further studies are needed to determine whether the sex ratio recorded in captures resembles reliably the natural sex ratio of the given population, or it is distorted. It appears that traps baited with pear ester + acetic acid present a useful alternative for monitoring codling moth especially in mating disruption treated orchards where pheromone traps do not work, or in any other situations where for any reason the capture of female codling moths is sought for. The lower efficiency of the pear ester + acetic acid bait can easily be overcome by applying more traps for monitoring at a given site.
