Abstract
The effect of pure gossypol or of extracts of a high gossypol cotton strain on the feeding rate of larvae of Spodoptera littoralis Boisduval was investigated by the ‘Styropor method.’ Styropor (foamed polystyrene) lamellae were painted on one side with 5% sucrose and on the other side with a solution of 1, 0.5, 0.25, and 0.1% pure gossypol. One percent gossypol strongly suppressed feeding, and a negative correlation was found between the feeding rate on the lamellae and the concentration of gossypol. Larvae fed about half as much on lamellae painted with the leaf extract of a high-gossypol-content cotton strain (HG6-11-144) as on those painted with an exract of the glandless strain Acala 63-74.
