Interpretive Summary: The attractiveness of three trap types to whitefly and whitefly parasite adults was compared in two choice experiments in a greenhouse at the Centro de Ciencias Medioambientales, Madrid, Spain. Yellow sticky cards equipped with light-emitting-diodes (LED-YC) caught more adults per trap per day than yellow sticky card (YC) traps. YC traps caught significantly more whitefly and whitefly parasite adults than plastic cup traps equipped with light-emitting diodes (LED-plastic cup traps). However, the LED-plastic cup traps caught fewer whitefly parasite than the YC traps. The results suggest that LED-plastic cup traps are compatible with whitefly parasite in greenhouses in which parasites are released to reduce the whitefly nymph population.

Technical Abstract: The attractiveness of three trap types to Bemisia tabaci (Gennadius) B-biotype (= Bemisia argentifolii Bellows & Perring) and Eretmocerus mundus Mercet adults was compared in two choice experiments in a greenhouse at the Centro de Ciencias Medioambientales, Madrid, Spain. Yellow sticky cards equipped with light-emitting-diodes (LED-YC) caught more adults per trap per day than yellow sticky card (YC) traps. YC traps caught significantly more B. tabaci and E. mundus adults than plastic cup traps equipped with light-emitting diodes (LED-plastic cup traps). However, the LED-plastic cup traps caught fewer E. mundus than the YC traps. The results suggest that LED-plastic cup traps are compatible with E. mundus parasites in greenhouses in which parasites are released to reduce the B. tabaci nymph population.
