The green peach aphid, Myzus persicae(Sulzer) (Hemiptera: Aphididae), is an important pest of several worldwide crops. This study evaluated the effects of plant micronutrients (alpha-iron (Fe), zinc sulfate (Zn), copper sulfate (Cu), and manganese sulfate (Mn)) on digestive enzymes, intermediary metabolism, and antioxidant responses of M. persicae reared on bell pepper plants under greenhouse conditions. Results showed that M. persicae reared on Mn-treated plants had the digestive enzymes α-amylase, trypsin, chymotrypsin, and elastase inhibited. Moreover, the aphids fed on Mn-treated plants showed the highest activities of catalase, glucose-6-phosphate dehydrogenase, superoxide dismutase, and peroxidase, and lower increase rate of malondialdehyde. These findings indicate that micronutrients can impact the aphid metabolism, which may aid control strategies against this insect pest. We raise the potential for beneficial use of foliar fertilizer application as a pest management tool that could be further evaluated on a production and economical scale, as well as with other insect pests.
