Title: In vitro ovicidal and larvicidal activity of Butea frondosa (Palas) seeds extract on Haemonchus contortus
Abstract: The seeds of Butea frondosa were collected and subjected to extraction using both organic and inorganic solvents. The extracts were evaluated for anthelmintic property against exogenous stages of Haemonchus contortus. All the four extracts of B. frondosa seed were found to have significant effect (p < 0.05) on egg hatching at the concentration of 1.25 mg ml−1. The corrected mean hatching in H. contortus eggs ranged from 0.86±0.49 (alcoholic extract) to 3.56±0.99% (ether extract). Contrary to the effect on egg hatching, at the similar concentration, the extracts of B. frondosa failed to reveal any appreciable effect on egg embryonation. On larval mortality assay, aqueous extract @ 20.0 mg ml−1) caused 90.73% mortality in infective larvae of H. contortus at 72 hours post-incubation while other extracts exhibited low to moderate larvicidal activity.
