本研究表明,螟卵啮小蜂幼虫期的滞育主要由光照时间的长短所决定。造成幼虫滞育的临界光照时间在12小时到12小时30分之间。短日照控制滞育的温度上限为24℃左右。螟卵啮小蜂对光照的敏感虫态为早期幼虫,在短光照持续作用下,发育到老熟幼虫即进入滞育。短光照持续作用能较长时间地控制螟卵啮小蜂幼虫期的滞育。滞育一个月的老熟幼虫转入25℃长光照下,其羽化率为95.16％;滞育两个月的,羽化率仍达64.29％。 This study shows that diapause larval stage larvae Diapause larvae mainly by the length of the light of the decision. The critical light time for larval diapause is between 12 hours and 12 hours and 30 minutes. Short-day control of diapause temperature upper limit of about 24 ℃. Bombyx mandarina was sensitive to light as the early instar larvae, under the continuous action of short light, the development of mature larvae into the diapause. Short-term light continued to control the larvae of larvae for a long time to control diapause larvae. The larvae rate of mature larvae that diapause for one month to 25 ℃ long-term light was 95.16%. For two months of diapause, the emergence rate was still 64.29%.
