In-vitro Acaricidal Study of Calotropis Gigantea Methanolic Extracts against (Rhipicephalus (B.) microplus) Ticks in Udaipur, Rajasthan, India

The present research was conducted to find out acaricidal efficacy of methanolic extracts Calotropis gigantea against Rhipicephalus (Boophilus) microplus ticks in Udaipur (Rajasthan). Larval packet Test (LPT) and Adult Immersion (AIT) were used evaluate efficacy. A total four concentrations the extract (12.5%, 25%, 50%, 100%) along with one control group twice replications for each concentration bioassay. Highest both in-vitro tests (AIT LPT) recorded 100% gigantea. displayed highest IO% at concentration, which determined be 67.46% AIT. had a minimum reproductive index 0.16. During study, it clear that AIT lower higher percent oviposition inhibition. LPT demonstrated 64%. mortality increased trend increasing plant extracts.
