利用球形芽孢杆菌TS—1水悬剂在野外水体连续8年灭蚊幼虫。试验表明:使用1—15ppm浓度,每毫升含菌量10~3—10~4,24小时后,防治淡色库蚊幼虫效果90％以上;对凶小库蚊幼虫可达48—94％。使用浓度在10ppm以内时,有效期5～7天,残效与投药浓度成正比。多次坑沟水体7280m~3试验,TS—1灭蚊效果好,对水生生物无不良影响, The use of Bacillus sphaericus TS-1 suspension in the wild water eight consecutive years of mosquito larvae. Experiments show that: the use of 1-15ppm concentration per ml of bacteria 10 ~ 3-10 ~ 4, 24 hours after the control of Culex pipiens larvae effect of more than 90%; Culex pipiens pallens larvae up to 48-94%. Use the concentration of less than 10ppm, the validity of 5 to 7 days, the residual effect is proportional to the concentration and administration. Several pit ditch water 7280m ​​~ 3 test, TS-1 mosquito control effect is good, no adverse effects on aquatic organisms,
