Newly hatched larvae are polyphagous and will feed on many kinds of non-hostplants although they are not able to grow on them. They become oligophagous when they are reared on solanaceous plants but remain polyphagous when reared on diet. The critical period for induction is in the first instar. The induced oligophagous behaviour can be reversed by forcing larvae to feed on diet.}, number={4}, journal={JOURNAL OF INSECT PHYSIOLOGY}, author={YAMAMOTO, RT}, year={1974}, pages={641–650} }
