Abstract:
The present research was designed to evaluate acaricidal efficacy of methanolic extracts of Datura Stramonium against cattle tick Rhipicephalus (Boophilus) microplus in Udaipur (Rajasthan). Acaricidal efficacy was evaluated Larval packet Test (LPT) and Adult Immersion Test (AIT). Four concentrations of the D. Stramonium extract (12.5%, 25%, 50%, and 100%) and one control group with twice replications for each concentration were used in the bioassay. The Highest efficacy in both in-vitro tests (AIT and LPT) was recorded in 100% methanolic extracts of D. stramonium. The methanolic extracts of D. stramonium has highest IO% at 100% concentration which was 67.46% in AIT. The 100% concentrations of methanolic extracts showed minimum reproductive index (0.16). In AIT the decrease in reproductive index with increase in the percent inhibition of oviposition, was evident during the study. In LPT, methanolic extracts of D. stramonium has highest efficacy at 100% concentration which was 64%. Larval mortality increased with increasing concentrations of plant extracts.
