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17.8 d；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 ...
