摘要
目的明确实验用淡色库蚊、白纹伊蚊不同性别羽化时间段,确定实验用虫最佳取蚊时间,以提高工作效率,保证药效实验的快速顺利完成。方法对2种试虫进行标准化饲养,研究不同羽化时间段雌雄蚊的数量及比例。结果淡色库蚊和白纹伊蚊蛹开始羽化后,均在第2、3天达到高峰,且羽化成蚊主要在前4天内完成;在整个羽化过程中,前2天羽化成蚊以雄蚊占绝大多数,之后雌蚊比例逐渐增加;羽化结束,雌雄性比接近1:1。结论在驱、灭蚊制剂药效登记实验中,取第3～4天羽化的蚊虫作为实验用蚊备选群体,雌虫比例高,可方便、快捷地满足实验需求。
Objective To identify the eclosion time of Culex pipiens pallens and Aedes albopictus for best getting the experimental females. Methods Rearing Cx. pipiens pallens and Ae. albopictus with standard rearing technique and study on numbers of females and males at different time of eclosion. Results The peak of adult emergence occured at 2nd and 3rd day after eclosion and most adults emergenced within 4 days. Adults was predominantly male about 2 d prior to adult eclosion. Two days later, females were the main part of emergenced adults. After all adults emergenced, gender ratio was close to 1 ： 1. Conclusion Taking adults emergencing at 3-4 day will obtain high ratio of females which as materials for pesticide registration could meet the needs of experiment.
