蚜小蜂

研究表明，在自然状态下丽蚜小蜂100%感染Wolbachia，其孤雌产雌的生殖方式是由体内共生的Wolbachia引起的，并已成为它的固有生殖模式。

Researches have shown that thelytoky in E. formosa is caused by Wolbachia and this mode has become its stable reproductive way .

利用核糖体28SrDNAD2与D3扩展区、线粒体细胞色素氧化酶、核糖体内转录间隔区等DNA序列分析研究蚜小蜂的系统进化等。

While the systematic evolution study of aphelinid parasitoids includes the sequencing of 28S rDNA D2 and D3 expansion region , cytochrome oxidase ( CO ⅰ, CO ⅱ) and rDNA internal transcribed spacer ( ITS1 , ITS2 ) .

研究结果表明，丽蚜小蜂中Wolbachia的密度随不同羽化天数的动态变化过程是先缓慢上升，再快速上升，最后下降的一个趋势。

The results showed that Wolbachia density dynamic in whole adult wasp was a progress with an initial slow raise , then a quick raise and finally a decrease trend .

丽蚜小蜂褐蛹随贮存时间的延长其羽化率等显著下降。

The emergence rate of the wasps was positively correlated with the storage temperature , and negatively correlated with the length of the storage duration .

对松突圆蚧与松突圆蚧花角蚜小蜂的种间关系用微分方程组模型进行了研究。

A set of differential equations was established to describe the interaction between Hemiberlesia pitysophila Takagi and Coccobius azumai Tachikawa based on the investigation data in various fields .

在温度平均为26.7℃下，丽蚜小蜂成虫寿命为23.5±1.3天，繁殖力128.9±6.9粒/雌、繁殖率5.5±0.2拉/雌/日。

At temperature 26.7 ℃ on average , the life & span , reproductive capacity and egg laying frequence of E. formosa was 23.5 ± 1.3 days , 128.9 ± 6.9 eggs / female and 5.5 ± 0.2 eggs / female / day , respectively .

苹果绵蚜体表的绵状蜡质在蚜小蜂寻找寄主过程中有促进作用，清理粘在身上的蜡质是该蜂寄生过程中的重要环节。

The lanose wax on the body surface of woolly apple aphid can promote the parasitoid to search the host , and removing the wax is also important step for the parasitoid to lay its egg .
