Abstract

Five lemon leaf extracts were tested as antifeedants for the
cotton leafworm, Spodoptera littoralis (Boisduval), where
Chloroform, methanol, carbontetrachloride, ether and n-hexane
were used. In choice tests; where larvae were offered treated and
un-treated cotton leaf discs, extracts of the three latter solvents
were very effective on 3rd instar larvae. The chloroform extract was
effective, while the methanol extract had no such effect. In nonchoice tests; where larvae were offered only treated cotton leaf
discs, more than 97.0% feeding inhibition was observed with
chloroform (weakly polar); 98.6, 83.0 and 95.7% for
carbontetrachloride, ether, and n-hexane, (non-polar), respectively.
These results indicate that Citrus limon L. leaves contain
chemicals that serve as antifeedants for S.littoralis larvae
