摘要: 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。

Abstract: A laboratory experiment was conducted to study the effects of breeding with the Pinus tabuliformis needles from different stand types on the growth and development of Dendrolimus tabulaeformis with differentcolored morphs. Compared with yellow morph larvae, black morph larvae had the characteristics of fast body weight growth, heavier female pupa, larger fertility, and higher survival rate. Breeding with the P. tabuliformis needles from mixed stand prolonged the larvae development duration and restrained the larvae growth and development, as compared to the breeding with the needles from pure stand. It was suggested that the P. tabuliformis needles from mixed stand could contain unfavorable substances for the development of D. tabulaeformis larvae.
