Description The antibiotic activity of some compounds, and of plant extracts, was bioassayed by incorporating them in a wheat germ diet developed for rearing cotton spotted bollworm (Earias vittella F.). Acetone extract of square powder caused maximum mortality followed by gossypol, tannic acid, other tannins and anthocyanins. Hexane extract of bolls did not affect larval survival. Rutin, anthocyanins and ether fractions of the ethanol extract decreased % pupation of larvae while in diets containing gossypol and tannic acid, none of the larvae could reach pupal stage.

Some of the larvae were unable to spin the silken cocoons when reared on diets containing gossypol, tannins, anthocyanins and rutin. Tannins and anthocyanins increased the developmental period of insects. All the compounds or solvent extracts except hexane extract of bolls decreased pupal weight. It is suggested that gossypol, tannins, anthocyanins and other secondary substances present in cotton squares and bolls could be utilized as a source of biochemical resistance against E. vittella.
