Abstract:
The objectives of this study were to evaluate the Acaricidal activity of the aqueous extracts of Azadirachta indica (seed, leaves and bark) against cattle tick, Rhipicephalus (Boophilus) microplus in Udaipur (Rajasthan) with various morphological details of cattle ticks. The Percentage larval mortality, inhibition of oviposition (IO%) and reproductive index were studied at various serial concentrations (70%, 50%, 25% and 10%) and one control group with twice replications for each concentration were used in the bioassay. The larval packet test was performed parallel to the adult immersion test for engorged female ticks for three aqueous extracts of A. indica. An aqueous seed, leaves and bark extract of neem was showed mortality of 54%, 56.5% and 36% respectively at 70% concentration LPT after 24 hrs. of treatment. Tick species and seed, leaves and bark extract concentration had significant effect on tick mortality (P< 0.05). As per results for AIT showed aqueous seeds, leaves and bark extract of A. indica at 70% concentration was IO% 54.27%, 62.05% and 36.57% respectively. In aqueous extracts of seeds, leaves and bark reproductive index (0.21), (0.17) and (0.29) were observed at 70 mg/ml concentration among the three extracts of A. indica evaluated.
