| 摘 要： | 研究了室温条件下悬铃木方翅网蝽(Corythucha ciliata(Say))若虫密度与其羽化成虫的性比、寿命和产卵量的关系,发现若虫饲养密度与性别分化和成虫寿命无显著关联,而对单雌产卵量有一定影响,10头若虫/叶时的单雌产卵量最高,达到171.8675粒/♀,显著高于2～4头若虫/叶的95.3333～100.1250粒/♀。

| Abstract: | Corythucha ciliata(Say) is a newly alien pest in China.Rearing the nymph of the lacebug under room temperature,the relationship between the nymph density and the sex ratio,longevity and oviposition number per female of its emergenced adults were investigated.The results showed that the nymph density had no significant correlation on adult sex differentiation and longevity while having a certain influence on the oviposition number per female.When rearing under 10 nymphs per leaf,the oviposition number per fe... |
