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