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。

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.
