Journal Title: Asian Pacific Journal of Tropical Disease - Year 2012, Vol 2, Issue 3
Abstract
Objective: To study the effect of ethanolic extract of leaves of the plant Jatropha curcas as a step towards developing a safe and ecofriendly therapeutic agent to combat the problems of tick and tick-borne diseases. Methods: Pulverised leaves of J. curcas were subjected to soxhlet extraction using ethanol. The ethanolic extract of J. curcas at different dilutions such as, 50, 60, 70, 80, 90 and 100 mg / ml were tested against ticks using adult immersion test. The per cent adult mortality, inhibition of fecundity and hatching of laid ova were studied. Results: The extract caused significant blocking of hatching of the laid ova by the treated ticks. Conclusions: Eclosion blocking effect of J. curcas extract is a promising property of the plant that can be utilized for controlling the population of ticks.
