Screening of methanol extract of Sclerocarya birrea root bark as antifeedants for Tribolium casteneum

Abstract

The methanol extract of Sclerocarya birrea (A. Rich) Hochst was screened for antifeedant activity
 against the stored product pest in maize, Tribolium casteneum.  It was found to be a good antifeedant for
 the insect at various concentrations based on the antifeedant index calculated.  Preliminary investigation
 of the active constituents indicates that the hydrolysate of the extract contains a phenolic compound that
 might be responsible for the antifeedant activity observed.
