| Abstract: | This paper represents the results of some digestive and esterases enzymes dynamics of the diamondback moth larva after cantharidin feeding before death. The results showed that the average activities of Proteinase, Lipase, and acid Phospharatase decreased by 8.71%, 15.69% and 25.33% respectively except that of a-amylase increased 6.75% , but all of them had no statistical differences from that of CK. The activities of AchE and Carboxylesterase had statistical increases by 74.37% and 210.57% respectively. The test insects were lazy in their activity after cantharidin feeding and gradually to death. It suggested that the chemical has different poison mechnism from the most applied organophosphate pesticides. |
