✦ Synopsis

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.
