The effect of topical application of neem seed extract on sheep infested with tickAblyomma variegatum was examined for acaricidal and repellant activity. The seed extract showed acaricidal activity at 5.0, 2.5 and 1.0% concentration in vitro. The extract had no acaricidal activity in vivo. However, it showed a repellant activity against ticks at 5.0 and 2.5% concentration. The activity of the extract seems to be concentration dependent. The extract appears to have some potentials as a repellant or antifeedant and could provide an inexpensive integrated pest management resource for farmers.
Key words: Acaricidal, repellant, ticks.
