مستخلص: Background: Tick infestation particularly, of Riphicephalus microplus is a costly affair for farmers particularly in times of emerging resistance. Biological control using plant extracts will serve as environment friendly and cost-effective method. The present study was taken up to investigate the phytoconstituents and acaricidal activities of ethanolic extract of Calotropis gigantea flowers. Methods: The acaricidal ef f icacy of ethanolic extracts of Calotropis gigantea f lowers against engorged adult females of R. microplus were accessed by measuring mortality, inhibition of oviposition, hatching rate and larval mortality through Adult Immersion and Larval Packet Test. Gas chromatography-Mass spectrometry (GC-MS) analysis was done to reveal various compounds found in the flowers of Calotropis gigantea to justify their acaricidal activity. Result: As per the results of the in vitro tests (adult immersion test and larval packet test), there was adult mortality of 56.67%, RI of 0.17, IO of 66% and larval mortality of 60.33% at concentration of 100 mg/ml. LC50 values were found to be 83.18 mg/ml. The GC-MS analysis revealed the presence of two major phytocompounds: dibutyl phthalate and n-Hexadecanoic acid in the extracts suggesting potential acaricidal properties. Results of the present study revealed the ethanolic extracts of Calotropis gigantea flower have potential anti-tick activity against both larval and adult stage of Rhipicephalus microplus.
