本文报道1987～1989年在印度Shahjahanpur和Allahabad地区乡村控制水井中蚊虫(?)生研究的结果。试验井位于Dadrol(Shahjahanpur)和Shankargarh(Allahabad)区生物环境控制疟疾科研规划区内,包括Dadrol区的26个试验村和5个对照村;Shankargarh区的10个试验村和3个对照村。将井分为“使用的”、“偶然使用的”和“不用的”三种。在Dadrol不用的井中15口蚊幼虫阳性,在Shankargarh区33口井蚊幼虫阳性,这些井均用EPS处理,每口井用量是85gm/1000cm~2。用一个5升的铁吊桶舀取井水测量处理前后的蚊幼虫密度,从每口井共舀取5桶,每口井的蚊孳生密度以5桶
This paper reports the results of mosquito breeding in rural controlled wells in Shahjahanpur and Allahabad districts of India from 1987 to 1989. The pilot wells are located in the biosphere-controlled malaria research area of Dadrol (Shahjahanpur) and Shankargarh (Allahabad), including 26 pilot villages and 5 control villages in Dadrol district; 10 pilot villages and 3 control villages in Shankargarh district. Wells are divided into “used”, “occasionally used” and “not used” three. Fifteen mosquito larvae were positive in wells that were not used in Dadrol, and mosquito larvae were positive in 33 of the Shankargarh districts. All of these wells were treated with EPS at a rate of 85 gm / 1000 cm -2 for each well. A 5-liter iron bucket was used to scoop the density of the mosquito larvae before and after the well water treatment. A total of 5 barrels were scooped from each well. The density of mosquito breeding in each well was 5 barrels
