摘要: 目的:观察新型杀虫剂Trebon对印鼠客蚤(Xenopsyllacheopis)的毒效。方法:水浸法、喷粉法和药膜法。结果:(1)不同处理方法的灭蚤效果不同,其顺序为:水浸法>喷粉法>药膜法,LD100的最低值分别为5ppm、0.3和0.5mg/m2;(2)Trebon与奋斗呐和溴氰菊酯的毒效比较:当有效成分含量≥5mg/m2时,24小时死亡率均为100%;用KT50的倒数表示击倒速度,Trebon是奋斗呐的2.5倍(药膜法及喷粉法),是溴氰菊酯的8.2倍(药膜法);(3)Trebon在室温下的持效>365天(药膜法),50℃下>35天。结论:该药对印鼠客蚤和猫栉首蚤击倒速度快,死亡率高,持效期长,对人畜几乎无毒,既可室内外大面积施用,亦适用于宠物灭蚤。

Abstract: The toxicity of trebon, a new type pesticide lowtoxic to man and animals, has been studied on the rat flea Xenopsylla cheopis.It was revealed that ① the efficacy of trebon with following different treatment i.e.impropation > spreading> residual smearing, LD100 being 5ppm, 0.3mg/m2 and 5.0mg/m2, respectively;② although the 100% mortality (24 hour) can be expected with either trebon.or fendona or deltamethrin with the dose of 5mg/m2 and above, trebon showed a better knock-down effect than that of fendona or deltamethrin, the KT50 of trebon was 2.5 times that of fendona (spreading method), and 8.2 times that of deltamethrin (residual smearing); ③ when used as residual smearing, trebon can keep its efficacy more than 365 days under room temperature, and about 35 days at 50℃.
