- Abstract
To clarify the changes in enzyme activity of A. gossypii after eating cotton harmed by aphids .【Methods】 Catalase (CAT), peroxidase (POD), superoxide dismutase (SOD), acetylcholinesterase (AChE) and glutathione-S-transferase (GST) activities in A. gossypii were determined after it was fed on cotton induced by Ac. gossypii for 24 h, 48 h and 72 h.【Results】 A. gossypii after eating cotton induced by Ac. gossypii, Catalase (CAT), peroxidase (POD), superoxide dismutase (SOD), acetylcholinesterase (AChE), and glutathione-S-transferase (GST) activities showed upward trend. Except that SOD reached a maximum of 86.03 U/mg after 48h of Ac. gossypii induction,CAT, POD, AChE, and GST all reached their maximum values after 72 hours of induction of Ac. gossypii, which were 452.82 U/mg, 8.12 U/mg, 0.080,9 U/mg, and 52.24 U/mg, respectively. In the mutual induction of Ac. gossypii and A. gossypii, the feeding order and time of the two aphids had a great influence on the changes of enzyme activity in the later feeding of A. gossypii. The specific performance was: Cotton for the first time induced by Ac. gossypii had significant effects on the changes of CAT, SOD, AChE, and GST activities of A. gossypii that were fed later. The second A. gossypii induced cotton significantly affected the CAT and POD activities of the A. gossypii; The third Ac. gossypii induced cotton had a significant effect on the POD and AChE activities of A. gossypii in late feeding. The treatments of Ac. gossypii and A. gossypii that interacted to induce cotton to have the greatest effect on the five enzymes activities of A. gossypii that was fed later were as follows: treatment that had the greatest effect on CAT activity of A. gossypii was: Ac. gossypii-A. gossypii -Ac. gossypii were induced in sequence for 72 h-72 h-24 h; The treatment that had the greatest effect on POD activity of A. gossypii was: Ac. gossypii -A. gossypii -Ac. gossypii were induced in sequence for 72 h-72 h-48 h; The treatment that had the greatest effect on the SOD activity of A. gossypii was: Ac. gossypii -A. gossypii-Ac. gossypii were induced in sequence for 48 h-24 h-72 h; The treatment that had the greatest effect on the AChE activity of A. gossypii was: Ac. gossypii -A. gossypii -Ac. gossypii were induced in sequence for 24 h-72 h-48 h; The treatment that had the greatest effect on the GST activity of A. gossypii was: Ac. gossypii -A. gossypii -Ac. gossypii were induced in sequence for 72 h-48 h-48 h.【Conclusion】 Acyrthosiphon gossypii has the greatest effect on the enzyme activity of Aphis gossypii after feeding Ac. gossypii induced cotton for 72 hours; In the interactive induction of Ac. gossypii and A. gossypii,Ac. gossypii induced cotton for the first time, it has the greatest effect on the enzyme activity of A. gossypii in late feeding. The effects of the second A. gossypii induced cotton and the third Ac. gossypii induced cotton on the enzyme activity of A. gossypii were relatively small.
