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GB13 917.7-92、GB/T173 2 2 .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GB15 670 -1995。结果　室内测试对德国小蠊LT50 为 1.2d ;4d死亡率为 10 0 %。现场试验在投放饵剂第 1、10、2 0天后日本大蠊相关密度指数分别为 2 5 .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 >10 0 0mg/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。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, LT 50 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, LD 50 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.
