本文报道用9种不同密度(5～300mf/10μl)微丝蚴感染中华按蚊后,所进行的系列观察。结果表明:蚊体内微丝蚴的吸入量、感染强度与感染微丝蚴密度呈正相关;蚊虫存活率、宿主效率则与微丝蚴密度呈负相关。在本实验室条件下,蚊龄为3～5d、微丝蚴密度为200条/10μl时,中华按蚊感染后可获较多三期幼虫。本文对幼丝虫的黑化现象、宿主效率降低的原因进行了讨论;并按Kartman和Wharton实验
This article reports a series of observations made after 9 infections of Anopheles sinensis with 9 different densities (5 ~ 300mf / 10μl) of microfilariae. The results showed that there was a positive correlation between the amount of microfilariae invaded and the density of microfilariae in the mosquito. The mosquito’s survival rate and host efficiency were negatively correlated with the microfilariae density. Under the laboratory conditions, the mosquito age was 3 ~ 5d and the microfilariae density was 200 / 10μl, more larvae could be got after Anopheles sinensis infection. In this paper, the reasons for the blackening phenomenon of young filariasis and the reduction of host efficiency are discussed. According to the Kartman and Wharton experiments
