Interpretive Summary: We developed light equipped insect traps for detecting and monitoring pest insects in greenhouses. The light was produced from a light-emitting diode (LED). We found that when an LED light was attached to plastic cup or sticky card traps, the catches of pest insect were increased in greenhouse studies. Plastic cup traps equipped with 530 nm lime green LEDs caught more adult greenhouse whiteflies and silverleaf whiteflies. The catches of yellow sticky card and clear plastic sticky card traps equipped with lime green LEDs also increased for greenhouse whiteflies, silverleaf whiteflies, cotton aphids, and fungus gnats, but not whitefly parasites. The lime green LED equipped yellow sticky card traps have potential for use in greenhouses for insect detection, monitoring, and control.

Technical Abstract: Light-emitting diodes (LEDs) were attached to plastic cup and sticky card traps to improve pest insect catches in the laboratory and in greenhouses. Plastic cup traps equipped with 530 nm lime green LEDs caught more adult Trialeurodes vaporariorum (Westwood) and Bemisia tabaci (Gennadius) biotype B compared with plastic cup traps alone. Yellow sticky card (YC) and clear plastic sticky card (CS) traps equipped with lime green LEDs (LED-YC and LED-CS, respectively) caught more adult T. vaporariorum, B. tabaci biotype B, Aphis gossypii (Glover) and Bradysia coprophila (Lintner) compared with unlit traps of each type in greenhouse cage studies with shell beans, Phaseolus vulgaris (L.) and cotton, Gossypium hirsutum (L.). The lime green LED equipped YC traps have potential for use in greenhouses for insect detection, monitoring, and control.
