Adult whiteflies (Homoptera : Aleyrodidae), and whitefly parasitoids (Hymenoptera : Aphelinidae) response to cool white fluorescent light powered by alternating or direct current

摘要

Attraction of Bemisa tabaci biotype B (Gennadius), Trialeurodes vaporariorum (Westwood), and Trialeurodes abutilonea (Haldeman) whiteflies and Eretmocerus eremicus (Rose and Zolnerowich) and Encarsia formosa (Gahan) whitefly parasitoids to alternating or direct electrical current powered light sources was studied in a dark room. Fewer adults of all whitefly species were caught on Tanglefoot(R) coated transparent plastic cards placed between a whitefly release chamber and the direct current powered white fluorescent lights compared with alternating current powered fluorescent lights. Differences in catches of whitefly parasitoids in response to lights powered by alternating or direct current were not significantly different.
