摘要
对杨黄褐锉叶蜂雄性幼虫发育起点温度和有效积温进行研究的结果表明:杨黄褐锉叶蜂雄性幼虫在18、22、26、30℃4个温度下可正常生长发育,而在34℃条件下不能完成发育,不同龄期(共5龄)雄性幼虫的发育起点温度和有效积温存在差异,且不同龄期对二者的要求不一致,有效积温分别为37.68、30.26、29.18、42.55、75.01日·度,发育起点温度分别为6.07、5.61、8.84、8.67、5.50℃。杨黄褐锉叶蜂雄性幼虫期发育起点温度和有效积温分别为6.35℃和220.68日·度,发育历期预测式为N=220.68/(T-6.35)。
The threshold temperature and effective accumulated temperature of larvae of Pristiophora conjugata were studied under five constant temperatures. The results showed that female larvae of Pristiophora conjugata can normally develop at 18, 22, 26 and 30℃, but it can not be completed at 34℃. The developmental threshold temperature and effective thermal summation were different for larvae of different instars, and the requirement for both were not identical for different instars. Larvae stage developmental threshold temperature and effective accumulated temperature was 6.35℃ and 220. 68 degree -day, respectively, the predictive development duration for N =220. 68/(T-6.35).
