Effect of Acetamiprid and φ=5 ％ Amino Oligosaccharin on Aphis gossypii Activity of Stress Defence Enzyme
Study the effect of aphid gossypii fed with acetamiprid and cotton treated by φ=5％ amino oligosaccharin on protective enzyme activity and detoxifying enzyme activity in internal Aphis gossypii,it provided theoretical basis for the resistance mechanism and effective prevention of Aphis gossypii.1-2 age Aphis gossypii in greenhouse as objects,we determined the activities of three kinds of protective enzymes (superoxide dismutase,catalase and peroxidase) and three kinds of detoxifying enzymes(carboxylesterase,acetylcholinesterase and glutathione-s-transferase) in internal Aphis gossypii after different medicament spraying.The results showed that SOD,CAT,POD,CarE,GSTs and AchE activities in internal Aphis gossypii had a trend to inhibition at initial stage of treatments of acetamiprid and φ=5 ％ amino oligosaccharin after Aphis gossypii fed with the cotton;CarE activity behaved inhibition effect as first then activation and inhibition at last within 96h,it had activation effect on GSTs and AchE activity.This proved that acetamiprid and φ=5 ％ amino oligosaccharin disturbed the protection and detoxification system of Aphis gossypii,and had better control efficiency.
