Exposure to methoxyfenozide-treated surfaces reduces the responsiveness of adult male codling moth (Lepidoptera: Tortricidae) to codlemone and pear ester lures in a wind tunnel.
The responsiveness of male codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), exposed to surfaces treated with the ecdysteroid agonist methoxyfenozide, toward lures loaded with the synthetic sex pheromone codlemone and/or the pear ester kairomone were investigated in wind tunnel experiments. Five different kinds of commercially available codling moth monitoring lures (obtained from Tr6c6 Inc., Adair, OK) were used in the bioassay: Pherocon CM Standard lure (loaded with 1 mg of codlemone), Pherocon CM Long-Life L2 (loaded with 3.5 mg of codlemone), Pherocon CM 10X (loaded with 10 mg of codlemone), Pherocon CM-DA Combo (loaded with 3.0 mg of codlemone and 3.0 mg of pear ester), and Pherocon DA (loaded with 3.0 mg of pear ester). Results from the study revealed that male codling moth exposed to surfaces treated with methoxyfenozide and the surfactant exhibited a significant decline in responsiveness toward lures loaded with either codlemone or pear ester. The full impact of how this negative effect might alter current moth monitoring procedures in orchards receiving ecdysone agonist sprays requires further investigation.
