短时高低温对果蝇锤角细蜂存活率的影响
Effects of short-term high and low temperature on the survival rate of Trichopria drosophilae
摘要
Abstract
Trichopria drosophilae is one of the dominant parasitic natural enemies of Drosophila suzukii,with great biocontrol potential against D.suzukii.Under the background of global warming and frequent extreme climate events,it is important to clarify the effect of short-term high and low temperature stress on the survival of T.dro-sophilae.We examined the effects of short-term high and low temperature on the survival rate of T.drosophilae under laboratory conditions.Logistic model was used to fit the mortality rate of T.drosophilae with temperature changes.The temperature adaptation zones of T.drosophilae to temperature were divided based on the results of the model.The results showed that the survival rate of T.drosophilae decreased with increasing temperature(high tem-perature)or decreasing temperature(low temperature).The mortality of adult female and male T.drosophilae peaked at 35℃ and-8 ℃.The temperature zone of T.drosophilae was divided into:lethal low temperature zone below-7.51 ℃,sublethal low temperature zone between-7.51℃ and 7.06 ℃,suitable temperature zone between 7.06℃ and 29.82 ℃,sublethal high temperature zone between 29.82 ℃ and 35.01 ℃,and lethal high tempera-ture zone above 35.01 ℃.Short-term high and low temperature reduced the survival rate of T.drosophilae.Our results can provide a theoretical basis for the artificial propagation and efficient biocontrol utilization of T.dro-sophilae.关键词
