A remote-insect detection system was designed, constructed, and operated in typical southern Texas environments near fields of corn and cotton. The system electronically detected Heliothis zea (Boddie) and Heliothis virescens (F.) and automatically radio-telemetered event information to a programmed data processor (computer). Remote infrared moth detector units were installed in the field and baited with species-specific pheromone lures. A tone-coded radio frequency pulse was transmitted from the detector units when moths that responded to respective lures were detected. Numbers of moths detected were automatically collated by the computer each night at hourly intervals. The infrared detectors, associated control circuits, and radio transmitters were reliable in adverse weather conditions. The system was at least 92% accurate in counting the moths detected and was 100% accurate in reporting the detection of single moths as a first event each night. Detector-transmitter units within a field consumed a nominal 6 mW from a 6-V lantern battery that lasted about 11 mo.
