The effects on the attractiveness and responsiveness of three moth species exposed as adults to surfaces treated with the ecdysone agonist methoxyfenozide (RH-2485) were examined in a wind tunnel. Codling moth, Cydia pomonella (L.), redbanded leafroller, Argyrotaenia velutinana (Walker), and obliquebanded leafroller, Choristoneura rosaceana (Harris), 0-24h old, were exposed to treated surfaces for 48h, and the attractiveness of females and responsiveness of males were tested. Exposure to methoxyfenozide-treated surfaces did not seem to affect the attractiveness of codling moth females, however it significantly reduced the males ability to respond to females. Preliminary results regarding the attractiveness and responsiveness of redbanded leafroller and obliquebanded leafroller suggest a negative effect, but not as pronounced.
