摘要
二化螟绒茧蜂无滞育特性,全世代发育起点温度为11.6±1.4℃、有效积温为256.9±26.1日度,被该蜂寄生的二化螟幼虫田间空间分布型为n=1、n=2和n→∞的Neyman分布,该蜂对寄生密度的寄生功能反应符合Holling Ⅱ模型,对自身密度的寄生功能反应符合Beddington模型。
Apahteles Chilonis is a parasitic natural enemy of the larvae of asiatic rice borer in China. The developmental zero and were 11.56±1.39℃ and 256.87±26.13 day-degree respeetively. According to calculation, nine generations a year may be occurred in Yangzhou. The spatial distribution of the parasitized host larvae was fitted to Neyman with n=1, n=2, n=∞. The function response of A. chilonis for host density accords with Holling Ⅱ model.
