Abstract: 组建了5个不同温度(17,20,23,26和29℃)下绿盲蝽Lygus lucorum实验种群的生命表.结果表明:在17~29℃温度范围内,随温度升高绿盲蝽的发育速率加快,并符合Logistic模型;在实验温度范围内,若虫期、产卵前期、卵期和世代历期分别为10.04~27.63,8.33~19.33,6.74~15.00,25.11~61.96 d.绿盲蝽的若虫、产卵前期和卵的发育起点温度分别为9.45,7.28和6.28℃,有效积温分别为210.25、191.83和160.12日度,完成整个世代需要的有效积温为555.04日度.在实验温度范围内,23℃时绿盲蝽的世代存活率最高(82.3%),雌成虫的产卵历期最长(41.67 d),单雌繁殖若虫数最多(35.42头/雌),种群趋势指数也最高(14.58);在较低的温度(17℃)和较高的温度(29℃)下,绿盲蝽的的种群趋势指数分别仅为8.44和9.06,均不利于其种群数量增加.
