Abstract

The pear ester, ethyl (2E,4Z)-2,4-decadienoate can be an effective attractant for codling moth, Cydia pomonella, in pear orchards treated with sex pheromones.
Differences in the attractiveness of the pear ester relative to a sex pheromone lure were found within pear cultivars.
The pear ester outperformed high-load sex pheromone lures in Bartlett, DAnjou, and Comice but not in Bosc orchards.
The pear ester lure performed poorly in Bartlett orchards with high levels of codling moth, > 20 moths per trap per season and occurrence of fruit injury.
In general, the pear ester lure caught significantly more males than female moths.
More than 70% of females captured in traps baited with the pear ester were mated.
