以膜饲法给中华按蚊饲以含不同密度微丝蚴的血食,蚊体内丝虫的感染率和感染度随血食中微丝蚴密度50、100、150和200mf/20μl的升高而上升。幼丝虫的成熟率和实验感染指数在血食中微丝蚴密度较高时(200mf/20μl)有所降低。微丝蚴密度为50~150mf/20μl时,对蚊的生殖力、生殖营养周期及寿命基本上无影响,甚至产卵量有所增加,寿命有所延长;密度为200mf/20μl时才有一定程度的影响。因而认为,“马来丝虫-中华按蚊”是相互适应的“病原-媒介”系统。
The infection rates and infectivity of filarial filariasis in the mosquitoes were increased by 50, 100, 150 and 200 mf / 20 μL And rise. The maturation rate and experimental infection index of juvenile silkworms decreased when the density of microfilariae in blood was high (200mf / 20μl). Microfilaria density of 50 ~ 150mf / 20μl, mosquito reproductive performance, reproductive nutrition cycle and life basically no effect, or even an increase in egg production, life expectancy has been extended; density of 200mf / 20μl when there is a certain Degree of impact. Therefore, “Malayi insects - Anopheles sinensis” is a mutual adaptation of the “pathogen - media” system.
