【摘要】 本文报道了两种中草药混配杀虫液剂代号为Y-13、Y-17它们对印鼠客蚤（Xenopsyua cheopis）的毒力测定结果。用瓶膜接触法,Y-13的药膜剂量为0.2983ul/cm²（含原药液量）,对雌、雄蚤的KT₅₀分别为2.0833min、1.6825min。瓶膜残效可达1月,水磨石砖面和瓷砖面残效均为15天,玻璃面残效时间达120天。Y-17的膜剂量为0.4053ul/cm²（含原药液量）,对雌雄蚤的KT₅₀均为2.9635min,瓶膜残效可达半月,水磨石砖面残效小于15天,玻璃面、瓷砖面残效均为15天。两种药剂对该蚤10min内的击倒率及24h死亡率均为100％。结果表明,两种液剂对蚤具有速杀、高效的毒杀作用,且Y-13的残效时间比Y-17长,两种药物药源丰富,具有一定研究及开发的前景。更多还原
