Temperature is an important environmental factor which influences insects reproduction. In order to obtain the highest reproductive efficiency, Chrysopa septempunctata was fed with aphids at 15 #,25 # and 30 # respectively.The results indicated that oviposition period was prolonged obviously and oviposition quantity to a single female worm was the highest at low temperature of15#.

温度是影响昆虫生殖的重要环境因子，为了获得最高的繁殖效率，比较了在15℃、25℃和30℃的条件下用蚜虫做食料来饲养大草蛉，发现在低温15℃的条件下，单雌产卵量最高，产卵历期也较长。

Chrysopa sinica and Orius sauteri showed closely sympatricand synchronous with the two leaf mites,but wide niche breadthesof food recipes weaken their functions of predatorness when themites and A.citricela appear at the same time.

六、草蛉、小花蝽与两叶螨的时间同步性和空间同域性较强，但因其食谱生态位较宽，当叶螨与蚜虫并存时，便降低了它们对叶螨的捕食效能。

Not only is it colourful and pretty, but the humble coccinella beetle also preys on garden pests such as aphids and other bugs.

这些结果表明HrpNEa处理增强了甜瓜对蚜虫的抗性。

Among three microsatellite primers usually used in the aphid and three primers used in the study of the Aedes japonicus (Diptera:Culicidae), finally four primers were selected to amplify the different samples of the green peach aphid. The result showed that DNA samples could be well amplified.

在三条常用的蚜虫微卫星引物和三条用于对日本伊蚊Aedes japonicus 研究所用的引物中，最终选取了33.15 核心序列、4、8G、8G 四条引物对桃蚜的不同样本进行扩增，结果表明扩增效果较好。
