| 摘 要： | 为了明确温度对二点委夜蛾生长发育的影响,采用室内人工恒温饲养方法,设置16、20、24、28、32和36℃6种温度,研究不同温度对二点委夜蛾各虫态的发育历期、存活率及雌成虫产卵量的影响,并组建实验种群生命表。36℃的恒温条件下,二点委夜蛾不能完成其发育史。在16～32℃范围内,二点委夜蛾各虫态发育历期随温度的升高而缩短,其世代发育历期在32℃时最短,为27.17天;世代发育起点温度和有效积温分别为8.69℃和604.45日.度。在20～32℃时,成虫寿命随温度的升高而缩短,且雌雄个体间无明显差异。20℃和24℃时单雌产卵量较高,为283.8粒和261.8粒,二者差异不显著。24℃时二点委夜蛾的种群趋势指数和内禀增长率均最高,分别为82.0和0.82。表明24℃是二点委夜蛾生长繁殖的最适温度。
