  1. 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 .

  2. 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 .

  3. 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 .

  4. 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 .
