Interpretive Summary: To increase the sensitivity of yellow and blue sticky card traps we add lime green and blue light emitting diodes (LED), respectively, for better attraction. Results showed that trap efficacies were increased from 1.3 to 4.8 times depending on the target insects. For CC traps the efficacy for whiteflies was increased over six times. Add LED lights did not increase the trap catches of whitefly parasites.

Technical Abstract: We equipped yellow sticky card (YC) and CC traps with 530 nm lime green light-emitting diodes (LED-YC and LED-CC) and blue sticky card (BC) traps with 470 nm blue LEDs (LED-BC) to increase trap catches of several pest insects. The LED-YC traps caught 1.3, 1.4, 1.8, and 4.8 times more adult Trialeurodes vaporariorum (Westwood), sweetpotato whitefly Bemisia tabaci (Gennadius) biotype B, Aphis gossypii (Glover), and Bradysia coprophila (Lintner), respectively, compared with YC traps in greenhouse studies. The LED-YC traps did not catch more Eretmocerus spp. than the standard YC traps. The LED-CC traps caught 6.1 times more B. tabaci compared with unlit CC traps. The LED-CC traps caught few E. erimicus (Rose and Zolnerowich) and Encarsia formosa (Gahan) compared with YC traps. The LED-BC traps caught 8.1 times more adult Franklinella occidentalis (Pergande) compared with the unlit BC traps in field studies.
