摘　　要：【目的】明确变温对铃木氏果蝇(Drosophila suzukii)生长发育的影响,为铃木氏果蝇发生的预测预报及综合防治提供科学依据。【方法】以铃木氏果蝇为材料,在室内人工气候箱内设14～20、19～25、24～30、26～32和29～35℃5组变温饲养处理,测定铃木氏果蝇各发育阶段的发育历期,并用表现型(Performance)模型对铃木氏果蝇各阶段发育速率数据进行拟合分析。【结果】14～20、19～25、24～30和26～32℃变温条件下铃木氏果蝇均能完成整个世代生长发育,且各阶段的发育历期均随温度的升高而缩短,全代发育历期分别为33.81±0.64、16.64±0.34、13.16±0.37和12.26±0.69 d,29～35℃变温条件下铃木氏果蝇化蛹后蛹不能正常发育。在变温条件下,铃木氏果蝇世代的生长发育符合Performance非线性模型,该模型对其卵期、幼虫期和蛹期拟合的R2均在0.9000以上,预测得出卵、幼虫和蛹的发育起点温度分别为9.1、10.5和12.3℃,发育终止温度分别为32.2、32.5和29.5℃。【结论】在14～20、19～25、24～30和26～32℃变温条件下铃木氏果蝇均能完成整个世代生长发育,在29～35℃变温条件下不能完成世代生长发育。可运用Performance模型描述变温对铃木氏果蝇生长发育的影响。[Objective]In order to provide the basic reference for the future population dynamics prediction and inte-grated control for Drosophila suzukii,this study focused on the growth and development characteristics of D.suzukii un-der fluctuating temperatures.[Method]D.suzukii population samples was raised in manual climatic box in the lab under five fluctuating temperature conditions,including 14-20,19-25,24-30,26-32 and 29-35℃.The differences of the deve-lopmental duration of each stage were detected.Then,Performance model was used to fit the growth rates of each stage of D.suzukii.[Result]The whole growth and development stages of D.suzukii could be completed under four fluctuating temperature conditions including 14-20,19-25,24-30 and 26-32℃,and developmental durations of each stage were shortened with the increasing temperature.The complete developmental durations of D.suzukii were 33.81±0.64,16.64±0.34,13.16±0.37 and 12.26±0.69 d,respectively under the above four fluctuating temperatures.However,no pupae could develop into adult under 29-35℃situation.Under the fluctuating temperature conditions,the growth of D.suzukii was in line with Performance nonlinear model.The R2 of egg stage,larval stage and pupa stage fitted by this model was above 0.9000.The predicted initial temperatures for development for egg,larva and pupa were 9.1,10.5 and 12.3℃,and the stopping temperatures were 32.2,32.5 and 29.5℃.[Conclusion]Under the fluctuating temperature conditions(14-20,19-25,24-30 and 26-32℃),the whole growth and development stages of D.suzukii can be completed,but D.suzukii cannot develop to adult under 29-35℃.Performance model can describe the effects of fluctuating temperatures on development of D.suzukii.
