最近报道苏云金杆菌(H-14)和球形杆菌在实验室和现场对数种滞水和洪水按蚊有杀灭作用,而且球形杆菌对库蚊和按蚊的效果较前者为优,生物学活力更强。本文对两种生物防制剂作了比较。实验室试验的1%原液(悬剂)用水配成几种浓度不同的剂型待用。取4盎司的杯子各装水100ml,分别放置20条4龄哥伦比亚鳞蚊幼虫,在4～5种不同浓度的备用液中,经过2～3次测试,每种浓度取3个同样的样品
It has recently been reported that Bacillus thuringiensis (H-14) and C. difficile kill several kinds of waterlogging and Anopheles sinensis in the laboratory and in the field, and that the effects of C. difficile on Culex pipiens and Anopheles mosquito are superior to those of the former, biological vigor Stronger This article compares two biological control agents. Laboratory tests of 1% stock solution (suspension) with water dubbed several different concentrations of dosage stand. Take 4 ounce cups each filled with water 100ml, were placed 20 4-year-old Columbia scale mosquito larvae in 4 to 5 different concentrations of stock solution, after 2 to 3 times the test, each concentration to take the same 3 samples
