Abstract EN
Hexane, chloroform, and ethyl acetate extracts of Couroupita guianensis leaves were studied for ovicidal activity against S.
litura.
All the extracts showed ovicidal activity against S.
litura.
Maximum activity was noticed in hexane extract and it showed the least LC50 and LC90 values; the regression equation was also higher than the other extracts.
All the analyzed values showed homogeneity variance.
The active hexane extract was fractionated and eight fractions were isolated.
The fractions were studied at different concentrations.
Among the fractions, fraction 8 showed maximum ovicidal activity with least LC50 and LC90 values.
Fraction 8 differed statistically from the other fractions; the regression equation value was higher than the other fractions.
All the P values obtained from regression analysis were significant.
The results of the present investigation clearly suggest that the active fraction could be purified to isolate active compound(s) and could be used to develop an insecticidal formulation to control economically important agricultural pests.
