樟翠尺蛾种群动态与植物群落结构及气候因子的关系

On the basis of long-term (eight years) monitoring for the population dynamics of Thalassodes quadraria Guene and the structure changes of plant community as well as the climate factors in the monsoon evergreen broad-leaved forest in Dinghushan Biosphere Reserve, the interactions among them were studied. As the food resources and habitats, plants have strong effect on the population dynamics of the moth. As a feedback, the population dynamics of this insect species caused the structure changes of the plant community. Climate factors, especially rainfall, contributed much to the mortality and reproduction of the moth.

闵行区樟树害虫樟叶蜂、樟翠尺蛾的药剂防治研究

于2009-2010年研究了闵行区危害绿化带樟树的樟叶蜂、樟翠尺蛾的药剂防治。从室外药剂防治结果来看,10%虫螨腈、20%杀灭菊酯、5%氯氰菊酯、30%乙酰甲胺磷、20%除虫脲、1.8%阿维菌素、25%灭幼脲Ⅲ号药剂7d后对樟叶蜂、樟翠尺蛾防治效果在83.50%以上,具有一定的持续效果。

樟翠尺蛾的发生规律及其防治研究

樟翠尺蛾(Thalassodes quadraia Guenee)是樟树的重要食叶害虫。该虫在上海地区1a发生4代。初孵幼虫在樟芽,2龄后在樟嫩枝危害,一般幼虫很难发现。以老熟幼虫在枝叶上越冬。本文介绍了该虫的形态特征及其生物学特性,提出了防治措施。
