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.
