Acaricidal Evaluation of Aqueous Extracts of Datura stramonium against Rhipicephalus (B.) microplus Ticks in Udaipur, Rajasthan, India

The purpose of the current analysis was to determine the effectiveness of acaricidal Datura stramonium aqueous extracts. The effectiveness of acaricides against the tick Rhipicephalus (Boophilus) microplus in cattle was assessed from Udaipur District, India. Larval packet testing (LPT) and adult immersion testing (AIT) were employed in this study. D. stramonium extract was used at four different concentrations: 12.5%, 25%, 50%, and 100%, with one controlled group and two replications for each concentration. In both in-vitro tests, AIT and LPT, 100% aqueous extracts of D. stramonium showed the highest acaricidal efficacies. The D. stramonium aqueous extracts with the highest IO% at 100% concentration and 67.46% in AIT were found to have the highest efficacies. The 100% concentrations of aqueous extracts exhibited minimum reproductive index of 0.16. During the course of the study, there was a discernible decline in the reproductive index and an increase in the percent inhibition of oviposition in the Adult Immersion Test. Aqueous extracts of D. stramonium demonstrated the highest acaricidal efficacy at 100% concentration with 64% in the larval packet test. A rising trend in larval mortality was observed as plant extract concentrations rose.
