从我国部分地区土壤中分离到大量球形芽孢杆菌(Bacillus sphaericus)和苏云金芽孢杆菌(Bacillus thuringiensis)菌株,从中筛选出数株高效杀蚊菌株。毒力测定表明,3株球形芽孢杆菌(YD35-02、YD90-2及SPh04-01)摇瓶菌培养物的0.001%稀
A large number of Bacillus sphaericus and Bacillus thuringiensis strains were isolated from soil in some areas of China, and several strains of highly effective mosquito-killing mosquitoes were screened out. Toxicity assays showed that 0.001% dilutions of 3 B. sphaericus (YD35-02, YD90-2 and SPh04-01) shake flask cultures
