Abstract

The phosphatase activity of the 3rd instar larvae of the Asian corn borer(Ostrinia furnacalis) grown in Bt-transgenic corn was evaluated in the laboratory.The results showed that the acid-phosphatase activity in the larvae feeding in Bt corn leaf for 72 h was greatly lower than that of the CK fed with the non-transgenic corn.The alkaline-phosphatase activity of the larvae feeding in Bt corn for 24 h was decreased markedly and for 72 h was 0.3-fold than the CK.With the increase of feeding time with Bt corn and the phosphatase activity and the larval weight were also significantly decreased more than that of the CK.The change of phosphatase activity may be associated with the decrease of larval weight.
