SCREENING OF INDIGENOUS MEDICINAL PLANTS FOR THEIR ACARICIDAL ACTIVITY AGAINST CATTLE TICKS UNDER IN VITRO CONDITIONAbstract
The aqueous and alcoholic leaf extracts of Annona squamosa, Azadirachta indica and Calotropis procera were tested against the cattle ticks. The fresh and leaf powder extracts were tested individually and also in combinations under in vitro conditions. The extracts of A. indica showed maximum mortality rate of ticks followed by A. squamosa and C. procera when tested individually. In combination, the hot water extracts of leaf powder showed 100% mortality whereas ethanol and methanol extracts showed 83% and 80% of mortality respectively. Based on the above experimental results, it is confirmed that the selected plant materials possess more acaricidal activity against cattle ticks. Extracts in combination are more effective than single drug used. Since the herbal drugs are cost effective and easy to process, it can be used as an alternative medicine to control cattle ticks.
