实验测定了明纹柏松毛虫在17℃、21℃、25℃、29℃、33℃、37℃,RH 75%、光周期 L ︰ D=16 h ︰8 h 条件下,不同发育阶段的发育历期和速率。结果表明,(1)温度升高,明纹柏松毛虫各虫态的发育历期缩短,发育速率提高；(2)在17℃下完成整个世代需要297.8日,在33℃下完成1代则减少到122.3日。
實驗測定瞭明紋柏鬆毛蟲在17℃、21℃、25℃、29℃、33℃、37℃,RH 75%、光週期 L ︰ D=16 h ︰8 h 條件下,不同髮育階段的髮育歷期和速率。結果錶明,(1)溫度升高,明紋柏鬆毛蟲各蟲態的髮育歷期縮短,髮育速率提高；(2)在17℃下完成整箇世代需要297.8日,在33℃下完成1代則減少到122.3日。
실험측정료명문백송모충재17℃、21℃、25℃、29℃、33℃、37℃,RH 75%、광주기 L ︰ D=16 h ︰8 h 조건하,불동발육계단적발육력기화속솔。결과표명,(1)온도승고,명문백송모충각충태적발육력기축단,발육속솔제고；(2)재17℃하완성정개세대수요297.8일,재33℃하완성1대칙감소도122.3일。
Developmental durations and developmental rates of each life stage of Dendrolimus suffuscus il-lustratus were determined under RH 75 % ,L ︰ D=1 6 h ︰ 8 h and 6 temperature treatments of 17℃, 21℃,25℃,29℃,33℃ and 37℃.The results showed that (1 )the developmental durations decreased and developmental rates increased with increasing of the designed temperature.(2 )Growth span of the whole generation was reduced from 297.8d at 17℃ to 122.3d at 33℃.
