摘　　要：为有效防止斑翅果蝇疫情扩散,降低传播风险,本研究以斑翅果蝇(Drosophila suzukii Matsumura)卵为研究对象,对该果蝇在3.0±0.5℃和5.0±0.5℃下低温处理致死时间进行研究。通过卵分别在1℃、3℃、5℃、7℃、9℃、11℃、13℃、15℃、17℃等9个不同温度条件下进行孵化培养,以期摸索出斑翅果蝇相关致死低温。结果表明:在3±0.5℃和5±0.5℃条件下,斑翅果蝇卵的致死时间分别为5.4 d和9.5 d。通过回归模型推算,恒温培养斑翅果蝇卵的致死低温为6℃。In order to effectively prevent the spread of the Drosophila suzukii Matsumura and reduce the risk of spread,in this study,we used the eggs of Drosophila suzukii Matsumura to study the lethal time of the fruit fly at low temperature of 3.0±0.5℃ and 5.0±0.5℃ respectively. The eggs were incubated at different temperatures （ 1 ℃, 3℃, 5℃, 7℃, 9℃, 11 ℃, 13%, 15℃, 17℃） in order to explore the lethal low tem- perature. The results showed that the lethal time of eggs of Drosophila suzukii Matsumura was 5.4 d and 9.5 d at 3.0±0.5℃ and 5.0±0.5℃ respectively. Estimated by regression model ,the lethal low temperature of eggs of Drosophila suzukii Matsumura was 6℃.
