Effects of ethanolic extract of the leaves of Pongamia glabra and Gliricidia sepium against Rhipicephalus (Boophilus) annulatus

Abstract

The effects of ethanolic extracts of the leaves of Pongamia glabra and Gliricidia sepium against Rhipicephalus (Boophilus) annulatus were studied. Different dilutions of the extracts such as 50, 60, 70, 80, 90 and 100 mg/mL were tested using adult immersion test (AIT). The per cent adult mortality, inhibition of fecundity and hatching of laid ova were studied. Both extracts caused very low per cent adult tick mortality and inhibition of fecundity. Fifty per cent blocking of the hatching of laid ova in ticks treated with ethanolic extract of leaves of P. glabra was observed.
