一纹平腹小蜂(Anastatus albilsis A shme ad)是落叶松毛虫卵期的主要天敌之一。通过1984年在室内变温条件下,对该蜂有效积温及发育起点温度的初步研究看出,发育起点温度为7.45±1.02℃,有效积温为369.60±34.15日度,其可靠程度为90％。此资料可预测一纹平腹小蜂在自然界的发生代数,同时为人工繁殖提供依据,以确保适时放蜂,提高治虫效果。
Anastatus albilsis A shme ad is one of the main natural enemies of the larval caterpillars. According to the preliminary study of the effective accumulated temperature and developmental starting temperature of the bee under the condition of indoor temperature change in 1984, it shows that the starting temperature of development is 7.45 ± 1.02 ℃, the effective accumulated temperature is 369.60 ± 34.15 days, and the reliability is 90%. This data can be used to predict the occurrence of Algae in nature and provide the basis for artificial reproduction to ensure timely release of bee and improve the effect of pest control.
