【摘要】 通过文山松毛虫(Dendrolimus punctatus wenshanensis)实验种群整个世代的饲养,组建了松毛虫实验种群生命表,研究了温度、湿度、光照、饲养密度等因子对松毛虫实验种群的影响,实验表明,对于松毛虫实验种群而言,卵期、幼虫期的死亡率相对较高,分别达63.02%和87.81%。改变非生物气象因素可以适当加速松毛虫的发育。室内饲养时,幼虫的饲养密度最好控制在1166头/m~2以下,有利于保证幼虫的正常生长。更多还原

【Abstract】 Through feeding the whole generation of Dendrolimus punctatus wenshanensis experimental population in room conditions,we set up its population life table to study environmental factors as temperature,moisture,light and feeding density on differentiation of the population.It showed that the population had relative mortality in egg stage and larval stage which reached 63.02%and 87.81%respectively.Changing of non-biotic factors might accelerate the insects’ differentiation.Feeding density might as well keep at about 1166 individuals per square meter to let normal growth of the larva.更多还原
