摘  要:
通过室内沙芥饲养,构建了小菜蛾的实验种群生命表,结果表明:内禀增长率(rm),净增殖率(Ro),平均世代周期(T)和种群加倍时间(t)分别为0.186 4,76.304 8,23.251 9和3.718 6。分析小菜蛾种群对干扰的反应时间,发现其抗药性很强。

摘  要:
The life table of Plutella xylostella population was constructed in laboratory when it was fed on Pugionium cornutum.The results showed that intrinsic rate of increase(rm),net reproduction rate(Ro),mean generation time(T) and double population time(t) were 0.1864,76.3048,23.2519 and 3.7186,respectively.The strong resistance of Plutella xylostella to drugs was found by analyzing the reaction time of Plutella xylostella population to disturbs.
