Effect of UV-C Irradiation on Greenhouse Whitefly, Trialeurodes vaporariorum (Hemiptera: Aleyrodidae)

Greenhouse whitefly, Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae), is a serious pest of numerous crops grown in greenhouses and field-grown strawberry yr-round production areas California, USA. Problems with insecticide resistance have prompted the search for more sustainable methods their management. Here, we applied UV-C light treatments nightly 16 s (19.2 J m–2) over 6-wk period to tomatoes infested T. compared numbers adults, nymphs, eggs those on untreated plants. All life stages were significantly lower treated unexposed Additionally, there was no significant difference chlorophyll fluorescence activity. Our results indicate that reduce populations offer potential non-chemical method management tomato.
