The purpose of the study was to investigate what biotic and abiotic factors had an impact on the movement patterns of male oriental fruit moths. Male moths marked with fluorescent powder were released into commercial apple and peach orchards and recaptured with pheromone traps for 2-5 days. Recapture rates and weather data collected near the release points were interpreted in the context of the crops' phenologies. It was apparent that wind direction and speed, and temperature, at the time of peak moth activity may have been more influential than the host crops themselves.
