Transfer of penultimate instar larvae of Spodoptera littoralis from diet to potato leaves has resulted in a growth reduction of 50% and 30% mortality, approximately. Slightly slower growth of larvae fed on Bt-potato leaves than on Non-Bt ones is probably caused by a reduced rate of food consumption. The efficacy of food conversion is similar in both types of leaves. Feeding on the Bt-potatoes hampers the fecundity of emerged females and hatchability of their eggs. As a result, the insects developing on the Bt-potatoes produce approximately four times less progeny in comparison with those growing on the Non-Bt potatoes. Results showed that the presence of transgene may cause unexpected effects on the non-target insects.
