摘　　要：本文对扶桑绵粉蚧Phenacoccus solenopsis Tinsley的重要天敌班氏跳小蜂Aenasius bambawalei Hayat(膜翅目:跳小蜂科)的雌雄形态特征、发育起点温度和有效积温、在长沙地区的理论发生代数进行了研究。结果表明:班氏跳小蜂是扶桑绵粉蚧若虫-成虫期寄生蜂;在28℃下,班氏跳小蜂一代的历期为17.8d;成虫、卵、幼虫和蛹的发育起点温度分别为:14.42、15.29、14.89、15.18℃,发生一代的发育起点温度为14.62℃;成虫、卵、幼虫和蛹的有效积温分别为87.92、9.74、68.41、75.84日·度,发生一代的有效积温为249.92日·度;由此预测班氏跳小蜂在长沙地区一年可发生9代。This paper reports the results of a preliminary study on the morphological and biological characteristics,developmental threshold temperature of each life-stage,developmental threshold temperature,effective accumulated temperature and generation occurrence time of Aenasius bambawalei Hayat（Hymenoptera：Encyrtidae） ,in Chasha,China.The results show that the developmental duration of A.bambawalei is reduced to 17.8 d at 28℃.Developmental threshold temperatures of adults,eggs,larvae and pupae were 14.42,15.29,14.89 and 15.18℃,respectively.The effective accumulated temperature of adults、eggs,larvae and pupae was 87.92,9.74,68.41 and 75.84 day-degrees,respectively.Nine generations occurred in Chasha annually.These results provide a theoretical basis for the use of A.bambawalei as a biological control for Phenacoccus solenopsis Tinsley.
