溴氰菊酯是当代最高效的杀虫剂,但价格昂贵,抗性增长较快,而且复苏率不断上升,为了充分发挥该药的高效杀虫活性、降低用药成本、解决和延缓抗性的发展,自83年始我们对溴氰菊酯加增效剂的方法以家蝇为主要试虫作了大量的研究工作。通过实验室测定及现场应用结果表明,SV_1(增效剂)对溴氰菊酯有明显的增效作用。增效溴氰(溴氰菊酯加SV_1)对家蝇的LD_(50)为0.00296微克/蝇,共毒系数为133.8。KT_(50)与溴氰菊酯相似,分别为4.592和4.673分钟;半现场试验5分钟内(使用浓度为
Deltamethrin is the most potent insecticide of the present era, but it is expensive, its resistance is growing rapidly, and the rate of recovery is rising. In order to give full play to its high insecticidal activity, reduce the cost of medication, and solve and delay the resistance Since the beginning of the year 83, we have done a lot of research work on deltamethrin and its synergist using housefly as the main test insect. The results of laboratory tests and field application show that SV_1 (synergist) has a synergistic effect on deltamethrin. The synergistic LD_ (50) of housefly with bromoxynitrin (deltamethrin plus SV_1) was 0.00296 μg / f, with a co-toxicity coefficient of 133.8. KT_ (50) is similar to deltamethrin, 4.592 and 4.673 minutes, respectively; within 5 minutes of the half-field test (at a concentration of
