Antimetabolite Effects on Larval Feeding of Spodoptera eridania12

Tomato leaves soaked in solutions of 7 antimetabolite compounds were offered to larvae of Spodoptera eridania (Cramer) to determine whether these materials affect larval feeding and development. Thiouracil-treated leaves were not appreciably consumed by larvae, weight gain was poor, and only 1 adult was produced from 54 larvae fed this diet. Thiouracil apparently acts as a deterrent to larval feeding.
