9种灭蟑毒饵对美洲大蠊的诱杀效果研究

目的测定9种不同种类的灭蟑毒饵的不同浓度对美洲大蠊的实验室杀灭效果。方法采用GB/T13917.7-2009方法进行实验室试验,9种原药分别为茚虫威、氟蚁腙、氟虫腈、除虫脲、氟虫脲、乙酰甲胺磷、吡虫啉、硼酸、灭幼脲,每种毒饵原药含量设定为0.1%、0.5%、1%3个浓度梯度,测定结果统计标准按死亡为统计,针刺击倒虫体有反应不记在死亡率范围内。结果吡虫啉、硼酸、灭幼脲3种不同浓度的灭杀效果较差,0.1%、0.5%和1%氟虫腈对美洲大蠊成虫和若虫(IV~VI龄)灭杀效果最好,0.1%氟虫腈毒饵对美洲大蠊成虫的LT503 d,LT704 d,LT905 d,0.5%氟虫腈毒饵对美洲大蠊成虫的LT503 d,LT704 d,LT905d,1%氟虫腈毒饵对美洲大蠊成虫的LT502 d,LT703 d,LT904 d;0.1%氟虫腈毒饵对美洲大蠊若虫的LT503 d,LT704 d,LT905 d,0.5%氟虫腈毒饵对美洲大蠊若虫的LT502 d,LT703 d,LT905 d,1%氟虫腈毒饵对美洲大蠊若虫的LT502 d,LT703 d,LT904 d。结论通过筛选不同种原药及浓度梯度对比试验,得出氟虫腈对美洲大蠊灭杀效果最好。

Trapping effect of nine kinds of cockroach baits against Periplaneta americana

Objective To survey the efficacy of different concentration of nine kinds of poison baits against P. ameri- cana in the laboratory. Methods The nine kinds of original drug were indoxacarb, hydramethylnon, fipronil, di- flubenzuron, flufenoxuron, acephate, imidacloprid, orthoboric acid and chlorbenzuron. Every poison bait concentration was set to 0.1% ,0.5 % , 1%. By death statistics, knockout acupuncture reaction was not recorded in the mortality rate within the range. Results Imidacloprid, orthoboric acid and chlorbenzuron had less killing efficacy ,0.1% ,0.5% and 1% fipronil bait against P. americana adults and nymphs（4 -6 instar） that was the best efficacy. 0.1%o fipronil bait against P. americana adults ,the LTs0 〈 3 d, LTTo 〈 4 d, LTgo 〈 5 d ,0.5% fipronil bait against P. americana a- dults,the LTso 〈3 d,LT7o 〈4 d,LTgo 〈5 d,l% fipronil bait against P. americana adults,the LTso 〈2d LT7o 〈3 d, LTgo 〈4 d,0.1% fipronil bait against P. americana nymphs,the LTs0 〈3 d,LTT0 〈4 d,LTgo 〈5 d,0.5%0 fipronil bait against P. americana nymphs, the LTs0 〈 2 d, LT7o 〈 3 d, LTgo 〈 5 d, 1% fipronil bait against P. americana nymphs, the LTs0 〈 2 d, LT7o 〈 3 d, LTg0 〈 4 d. Conclusion By screening different kinds of orignal drugs and comparative test of concentration gradient ,fipronil bait against P. americana is the best.
