SCREENING OF INDIGENOUS MEDICINAL PLANTS FOR THEIR ACARICIDAL ACTIVITY AGAINST CATTLE TICKS UNDER IN VIVO CONDITIONAbstract
The acaricidal activity of leaf extracts of Annona squamosa, Azadirachta indica and Calotropis procera were tested against the cattle ticks under in vivo condition. Plants were extracted with methanol and water and the extracts were tested against the cattle ticks under in vivo condition. The aqueous and alcoholic extracts of A. indica showed maximum mortality rate of ticks followed by A. squamosa and C. procera when tested individually. In combination of plant extracts, hot water extracts of dried leaf powder showed 100% mortality of ticks on 5th day 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. Plant extracts in combinations are more effective than single drug used.
