Abstract: Objective:To evaluate the high activity poison bait against resistant German Cockroach.Method:Spraying.Baiting.Result:The density of German Cockroach decreased 96.1% after a day on the field treated with the poison bait at the dosage of 1-2 g/m²,and decreased 97.4% after 8 weeks.But the density of German cockroach decreased 30.3% after one day treated with the deltamethrin suspension at the dosage of 40 mg a.i./m²,and became no efficacy after 6 weeks,after 8 weeks on the same place treated with the poison bait the density decreased 95.1% for one day.Conclusion:The experiment result show that the poison bait have high and quick and persistent activity against the high resistan strains of Germant cockroach.It is harmless to mankind,and easy to use.

摘要： 目的:观察高效连锁杀蟑药饵对高抗药性德国小蠊的防制效果。方法:在试验现场用高效连锁杀蟑药饵,按1～2g/m2施放于墙角缝隙、橱柜抽屉等蜚蠊出没、隐藏处;溴氰菊酯悬浮剂采用重点喷洒方法,按40mga.i./m²喷药,作试验对照。结果:高效连锁杀蟑药饵在施药后第1d德国小蠊密度明显下降,下降率高达96.1%,至第8周德国小蠊密度下降率仍为97.4%;溴氰菊酯悬浮剂在施药后第1d德国小蠊密度下降率仅为55.4%,1周后为30.3%,现场防制基本无效,至第6周完全失效。8周后在喷洒溴氰菊酯的场所再施杀蟑药饵,1d后德国小蠊密度下降率达95.1%。结论:高效连锁杀蟑药饵在现场对高抗药性德国小蠊有高效、速效、持效,按上述使用剂量现场有效防制蜚蠊时间达8周以上。
