摘要: The pollution of heavy metals in agriculture has attracted increasing global attention. Heavy metals not only destroy the structure and function of soil but also transfer and accumulate among nutrient levels along the food chain, affecting the growth and development of plants and animals. In this study, we found that Cd could be transferred and accumulated along the food chain between Vicia faba L. and aphids. The carbohydrate content and the expression levels of trehalase (TRE), trehalose-6-phosphate synthase (TPS), and vitellogenin (Vg) were up-regulated or down-regulated over 5 generations of aphids after Cd treatment. These findings provide a theoretical basis for studying the toxic effects of heavy metals on phytophagous insects and their resistance mechanisms.
