通过室内饲养的方法,研究了油松两种林分类型针叶对不同色型油松毛虫生长发育的影响。结果表明:与黄色型幼虫相比,黑色型幼虫体重增长较快,雌蛹较重,怀卵量较大,存活率较高;与纯林油松针叶相比,混交林油松针叶延长了油松毛虫的发育历期、抑制了油松毛虫的生长发育,表明油松混交林针叶内可能含有不利于两种色型的油松毛虫幼虫生长发育的物质。
The effects of Pinus tabulaeformis and Pinus tabulaeformis coniferous forest on the growth and development of different color-type Dendrolimus punctatus adults were studied by means of indoor feeding. The results showed that compared with the yellow larvae, the black larvae gained faster body weight, heavier females, larger fecundity, and higher survival rate. Compared with the pure-type pine needles, The developmental duration of Dendrolimus tabulaeformis suppressed the growth and development of Dendrolimus tabulaeformis, indicating that the Pinus tabulaeformis coniferous forest may contain substances that are detrimental to the growth and development of two species of Dendrolimus punctatus larvae.
