Abstract
The effects of eight ions on the Monochamus alternatus cellulase activity in vitro were studied in this paper.The results indicated that the activity reduced differently when concentration of ions were added except Fe++ in experiment conditions.Among which the effects of Cu++ and Pb++ were obvious on cellulolytic enzyme complex: endo-β-1,4-glucanase(Cx-ase),exo-β1,4-glucanase(C1-ase) and β-1,4-glucosidase in their gut,and activity had declined by 13.19%～99.98% and 42.27%～100% respectively under different concentration gradients.
