摘　　要：Greenhouse whitefly （GHWF）, Trialeurodes vaporariorum （Westwood） is a very important pest of greenhouse plants, but its resistance to pesticides has rendered it difficult to control by chemical methods in recent years. Sterile insect technique （SIT） is a biological control method which has been used in Area Wide Integrated Pest Management （AWIPM）. This study conducted the possibility of sterilising GHWF adults by gamma radiations emitted from cobalt 60. Longevity of the adults, and the amount of egg laying and sterilisation of eggs were determined under the influence of 50, 60, 70, 80, 90 Gy doses under controlled conditions （65 ± 5% RH, 25 ± 2 ℃, L/D = 16/8）. Normal insects were considered as control （0 dose）. The best combination for mating of normal and sterile adults （normal male × normal female as control, normal male and irradiated female, irradiated male × normal female, and irradiated male × irradiated female） was studied using a factorial design （n = 4）. Results showed that the best irradiating doses were 70 and 80 Gy for females and males respectively. Longevity of irradiated males and females was not significantly different from that of non-irradiated specimens. The best mating model was irradiated males and females.
