以实验室驯化的中华按蚊,通过人胎盘膜,吸取含马来丝虫微丝蚴的新鲜兔血而获感染.在温度为25.5±1℃,相对湿度为75～85％的实验条件下,对不同密度微丝蚴血餐感染后的中华按蚊的产卵力及存活率等方面的变化作了观察。结果表明:当感染微丝蚴密度≥5.42mf/μl和≥2.69mf/μl时,感染蚊的第1次和第2次产卵数均显著下降;后者更甚于前者。而感染蚊的存活率,则随感染微丝蚴密度的上升而下降,这种变化主要表现在感染后的第1～12d。
Anatomy of the Chinese Anopheles sinensis laboratory, through the human placental membrane, containing fresh filariasis of Malay Filaria infection and infection at a temperature of 25.5 ± 1 ℃, relative humidity of 75 to 85% of the experimental conditions The changes of oviposition ability and survival rate of Anopheles sinensis after blood meal infection with different density microfilament were observed. The results showed that when the density of microfilariae was ≥5.42mf / μl and ≥2.69mf / μl, the first and second spawning number of infected mosquitoes significantly decreased, the latter was more than the former. However, the survival rate of infected mosquitoes decreased with the increase of the density of microfilariae infection, which was mainly manifested in the first 12 days after infection.
