The in vitro toxicity of neem seed oil (Azadiracta indica, family: Meliaceae, 'Dogon yaro' in Hausa -language) was tested against the larvae of a three-host tick, Amblyomma variegatum (family: Ixodidae or hard tick) parasitic to cattle commonly found in Nigeria. Undiluted neem oil (100% concentration) was found to kill all (100% mortality) the larvae after 48 h. The toxicity was concentration and time dependent.
对印楝籽油(印楝,楝科,豪萨语称“Dogon yaro”)的体外毒性进行了测试,受试对象是一种三宿主蜱——变异革蜱(硬蜱科或硬蜱)的幼虫,这种蜱寄生于尼日利亚常见的牛身上。未稀释的印楝油(100%浓度)在48小时后能杀死所有(100%死亡率)幼虫。毒性具有浓度和时间依赖性。
