栗蚕卵发育起点温度和有效积温的测定
Measurement of the Developmental Threshold Temperature and Effective Accumulated Temperature for Camphor Silkworm Eggs
【摘要】 栗蚕(Dictypoea japonica)是珍贵的野生泌丝昆虫资源。对解除滞育的栗蚕卵分别通过15、18、21、24℃恒温处理暖种,测定栗蚕卵的发育起点温度为(10.2±0.6)℃、孵化有效积温为(181.7±11.6)℃.d,表明一旦给予越冬后解除滞育的栗蚕卵9.6℃以上的温度条件,就可能使其开始发育,当有效积温达到170℃.d时便可孵化。该结果可作为栗蚕卵的人工越冬保护及暖种技术处理的理论依据之一。
【Abstract】 Camphor silkworm(Dictypoea japonica) is one of the rarest silk spinning insects.In present study,undiapaused camphor silkworm eggs were incubated under constant temperatures of 15,18,21 and 24 ℃,respectively.The developmental threshold temperature of camphor silkworm eggs was determined to be(10.2±0.6)℃,and the effective accumulated temperature for hatching to be(181.7±11.6)℃·d,meaning that the undiapaused eggs which have already passed winter would start development when they meet a temperature over 9.6 ℃ and hatch when the effective accumulated temperature reaches 170 ℃·d.The above results provide one of the theoretical bases for over-wintering protection and incubation technology of camphor silkworm eggs.
