Abstract: Objective To develop a high effective and hypotoxic bait using propoxur as the active ingredient.Methods The indoor effect was determined using the method of GB13917.7-92.GB/T17322.8-1998 for insecticide registered testing indoor effect.In the field test,to determine the PRI,2 houses were selected as the treatment and control,respectively.In the toxicity test,the method for toxicologic test(GB15670-1995) was used.Results In the indoor test,LT50 for Blattella germanica was 1.2 day,the mortaliy was 100% within 4 days.In the field test,the PRI for Periplaneta japanica was 25.7,17.3 and 9.8 and the killing rate was 66%,82% and 92.2% for 1,10 and 20 d treatment,respectively.In the toxicity test,LD50 was above > 1 000 mg/kg.Conclusion The prepared bait of propoxur with lasting effect and and hypotoxicity has both contact and stomach poison actions,at the same time,it is reliable and convenient.
摘要: 目的研制以残杀威为有效成分的高效、低毒饵剂。方法室内药效测定按农药登记卫生用杀虫剂室内药效试验方法GB13917.7-92、GB/T17322.8-1998;现场试验,选择居民住户两处,分别为试验区和对照区,观察相关密度指数(RPI);毒性试验采用农药登记毒理学实验方法GB15670-1995。结果室内测试对德国小蠊LT50为1.2d;4d死亡率为100%。现场试验在投放饵剂第1、10、20天后日本大蠊相关密度指数分别为25.7、17.3和9.8;杀灭率为66.0%、82.0%和92.2%。毒性试验,饵剂样品急性经口毒性LD50>1000mg/kg。结论残杀威饵剂具有触杀和胃毒双重作用,效果可靠,药效持久,毒性低,使用方便。
