摘要
松褐天牛 Monochamus alternatus Hope成虫交尾 ,雌雄均无专一性 ,既能一雄多雌 ,也能一雌多雄 ;交尾次数对产卵量和卵的孵化率无显著影响 ;成虫对产卵场所的树种和树性有显著的偏嗜性选择行为。据测定 ,在 6月下旬至 7月下旬平均卵期 4.0 4天 ,卵的孵化率为 85 .76%。
The result shows that the mating behavior of Monochamus alternatus has no specialization,times of mating have no significant effect on oviposition amount and hatchability.The adults have a selection of tree species and quality for its egg laying.Its average egg stage lasts 4.04 days and the hachability is 85.76%.
