拟除虫菊酯类杀虫剂虽种类繁多,但因对光不稳定、被击倒的害虫易复苏等,故易激发害虫对其产生抗性。当前,对几种拟除虫菊酯类药物联合使用,以增强杀灭效果及延缓抗性发展,已引起高度重视.为此,我们在1985年5～6月,应用日本住友化学工业公司生产的胺菊酯和丙烯菊酯混合气雾剂,对德国小蠊的敏感品系进行一次药效比较试验。现将结果报告如下:
Although a wide range of pyrethroid insecticides, but because of the instability of light, easy to recover pests were knocked down, it is easy to trigger pest resistant. At present, the use of several pyrethroid drugs in combination to enhance the killing effect and delay the development of resistance has attracted great attention.To this end, we applied Sumitomo Chemical Co., Ltd. amine from May to June of 1985 Intrusive pyrethrum and alfalfa mixed aerosols, Blattella germanica sensitive strains of a comparative test. The results reported below:
