Abstract

Tick infestation is commonly found in every commercial cattle farm and domestically reared cattle. Farm generally used acaricides to treat tick infestation; however finding new, cheap and alternative source of acaricides is a prime concern. Here, we investigated the in-vitro efficacy of verenda (Ricinus communis) leaves extracts to treat tick infestation. We prepared aqueous, methanolic and ethanolic extract of verenda leaves to apply on ticks. A total of 90 ticks (both hard ticks and soft ticks) was collected from cattle in local area of Mymensingh region and divided into 3 treatment groups: A (aqueous), B (ethanol), C (methanol) and D (control). All groups were sub-divided into 3 sub-groups on the basis of concentration of 1%, 2% and 3% treatments. Ticks were treated with different concentration of extract and observation of tick was performed 12, 24 and 36 hours interval. The whole experiment was repeated thrice. Our data suggests 3% methanolic extract confer highest efficacy against ticks and verenda leaves extract could be used alternatively as acaricides.
