Abstract
The insecticidal activity of acetone extracts of Cymbopogon citratus ( DC) Stapf., Momordica charantia L., Zingiber officinale (Ros.), Xylopi a aethiopica (Dunal) A. Rich., Ocimum gratissimum L. and Aframomum mel egueta (Ros.) K. Schum against the cowpea aphid, Aphis craccivora Koch was investigated. Z. officinale and A. melegueta extracts had the gre atest effect in causing mortality of A. craccivora and inhibiting its reproduction. Extract from M. charantia caused high nymphal mortality whilst extract from C. citratus also caused significant nymphal mortal ity, reduction of life span of adult aphids and inhibition of aphid re production.
