摘 要 ：在14～34℃范围内研究了温度对孟氏隐唇瓢虫实验种群生长发育的影响,结果表明,在14～29℃范围内,温度愈低,发育历期愈长,当温度达到32℃后,发育历期又略有延长。孟氏隐唇瓢虫世代发育起点温度为11.9℃,有效积温为452.3日度。孟氏隐唇瓢虫世代存活率以26℃最高,以34℃最低。在20～32℃范围内,孟氏隐唇瓢虫内禀增长率(rm)、周限增长率(λ)和世代净增长率(R0)均以26℃为最高,分别为0.0670,1.0693和61.42。在20～32℃范围内,在理论稳定年龄组配中,孟氏隐唇瓢虫成虫所占的比例均在19%以下。

Abstract:The effects of temperatures on laboratory population of Cryptolaemus montrouzieri Mulsant were studied.The temperature affected growth development of C.montrouzieri significantly.In the range from 14℃ to 29℃,the lower the temperature was,the longer the stage of growth development was.When it exceeded 32℃,the duration of growth development was longer than that at 32℃.The development threshold temperature and the effective accumulated temperature for the growth temperature of C.montrouzieri genera...
