杀灭越冬蚊是控制淡色库蚊虫源,降低翌年种群密度的重要灭蚊措施。本文报道越冬淡色库蚊过冬后繁殖力的实验观察。 淡色库蚊越冬蚊于1982年2月24日采自青浦曲水园假山洞。先在20±1℃温室中复苏,于3月2日首次用小白鼠喂血。继而将饱血蚊单管饲养。待血液消化卵子成熟(见滤纸上排有血便)后,小批量(不超过5只一组)放回20×20×20cm小蚊笼中产卵,并将卵块计数卵粒。产卵后继续喂血,单管饲养,重复上述过程.直至蚊虫死亡。共观察了24只过冬蚊.其结果见表1。
Mosquito killing mosquito is to control the source of the light color library mosquito, reducing population density the following year an important anti-mosquito measures. This article reports the experimental observation of the fecundity of overwintering Culex pipiens pallens overwintering. Culex pipiens overwintering mosquito was collected on February 24, 1982 from Qingpu Qu Shuishuiyuan rock cave. First in 20 ± 1 ℃ greenhouse resuscitation, on March 2 for the first time in mice with blood. Then will be saturated with blood monkeys feeding. After the blood digests the ovum to mature (see the bloody stool on the top of the filter paper), the small batch (no more than 5 groups) is returned to the 20 × 20 × 20cm small mosquito basket to lay eggs and the egg blocks are counted. Spawn and continue to feed blood, single tube feeding, repeat the process until the mosquitoes died. A total of 24 winter mosquitoes were observed.
