1987～1989年我们用拟除虫菊酯处理蚊帐防制蚊媒,在疟疾高发区实施成片灭蚊,低发区实施疫点灭蚊的方法,连续3年进行了灭效观察。结果:高发区兴文县1987～1989年共喷洒蚊帐285986顶,喷帐率达95.5～98.5%,有效药量9.6～14.0mg/m~2。灭蚊前1年(1986)发病率为120.8/万,1987年和1988年灭蚊后分别降至34.4/万和7.6/万,1989年降至5.5/万,3年下降95.4%,平均每年递减65.5%。低发病区泸州市中区1987～1989年在疟疾发病3～6天内处理疫点67个,喷洒蚊帐867顶。处理疫点前1年(1986)发病率为4.0/万,灭蚊后1987～
From 1987 to 1989, we used pyrethroid-treated mosquito nets to control mosquito-repellent mosquitoes, implemented mosquito-killing in areas with high incidence of malaria, and implemented mosquito-killing methods in areas with low incidence of malaria. Results: In the high incidence area of Xingwen County, a total of 285986 mosquito nets were sprayed from 1987 to 1989, accounting for 95.5% ~ 98.5%. The effective dose was 9.6 ~ 14.0mg / m ~ 2. The incidence of mosquito breeding in the first year of mosquito control (1986) was 120.8 / million. After the mosquito control in 1987 and 1988, it dropped to 34.4 / million and 7.6 / 10,000 respectively. In 1989 it dropped to 5.5 / 10,000 and decreased by 95.4% in three years. The average annual Decrease 65.5%. Low-incidence area Luzhou City Central District from 1987 to 1989, the incidence of malaria within 3 to 6 days to deal with 67 outbreaks, spraying mosquito net 867 top. One year prior to the outbreak of the epidemic (1986), the incidence rate was 4.0 / million and 1987 ~ after mosquito control
