从1966年以来,对一种索科线虫Reesi-mermis nielseni用于生物防制蚊虫幼虫曾进行了广泛的研究。本文作者选择11个孳生地,面积、水质、环境条件各不相同,但都没有索科线虫。10个孳生地用寄生前期的线虫处理1～3次,共20次,每平方米水面用虫数180～14,700条,处理后1～3天进行考核。其中8个孳生地用压缩手提喷射器喷撒线虫,在11个孳生地中有3个(2个也用寄生前期的线虫处理)用寄生后期的线虫处理,用手将线虫撒在水面。用作试验的线虫都是实验室内培养的。寄生前期的线虫对按蚊二龄、三龄和四
Since 1966, extensive studies have been conducted on the use of Reesi-mermis nielseni as a biological control of mosquito larvae. The author chose 11 breeding places, area, water quality, environmental conditions vary, but there is no Soccoides nematode. 10 breeding places with parasitic nematodes 1 to 3 times, a total of 20 times per square meter of water with 180 ~ 14,700 number of insects, 1 to 3 days after treatment assessment. Three of the 11 breeding sites (2 also treated with parasitic nematodes) were treated with a parasitic nematode using a compressed portable sprayer in 8 of the breeding places, and nematodes were sprinkled over the water by hand. The nematodes used for the experiments were all cultured in laboratory. Parasitic nematodes against the second, third and fourth anopheles mosquitoes
