【摘要】 将豆无网长管蚜在12、15、18、21、24和27℃及相对湿度80%的条件下进行饲养,结果表明,豆无网长管蚜1~4龄若虫在整个若虫期的发育起点温度和有效积温分别为1龄7.309 1℃,22.974 6日.度;2龄3.776 6℃,30.652 8日.度;3龄3.852 7℃,28.207 0日.度;4龄5.256 4℃,39.273 0日.度;若虫期4.874 3℃,125.848 7日.度。更多还原

【Abstract】 The developmental threshold temperature(DTT) and effective accumulated temperature(EAT) of the larvae and whole larval stage and whole generation of Acyrthosiphon pisum were determined under 80% relative humidity and 6 temperature treatments(12 ℃,15 ℃,18 ℃,21 ℃,24 ℃ and 27 ℃).The DTT of each instar larvae from 1st to 4th instar and whole larval stage were 7.309 1 ℃,3.776 6 ℃,3.852 7 ℃,5.256 4 ℃ and 4.874 3 ℃ respectively,and their EAT were 22.974 6,30.652 8,28.207 0,39.273 0 and 125.848 7 degree-day respectively.更多还原
