Interpretive Summary:

Technical Abstract: Yellow sticky card (YC) traps were modified with 530 nm lime green light-emitting diodes (LED-YC) to increase the efficacy of capture of Bemisia tabaci (Gennadius) and other greenhouse insects as compared with catches on standard YC traps. More adult B. tabaci (biotype-B) and fungal gnats, Bradysia coprophila (Lintner), were caught on LED-YC traps compared with standard YC traps. Likewise, more Delphastus pusillus (LeConte) (coccinellid predators), were caught on the LED-YC traps compared with standard YC traps in a greenhouse test with collard plants, but not in a test with melon plants. However, in tests on both crops, the LED-YC traps did not catch more Eretmocerus spp. (parasitoids of whiteflies) than the standard YC traps. Moreover, the capture of western flower thrips, Franklinella occidentalis (Pergrande) was not affected by the LED-YC trap compared with the standard YC trap. These results demonstrate the potential of using LED-YC traps in greenhouses for insect detection, monitoring, and control.
