植物化感物质与化学农药的交互抗性研究

Cross-resistance between Plant Allelochemicals and Pesticides

当前植物源农药与化学农药的施用处于并行阶段。农田生态系统中的害虫会同时经历这两种选择压,如果二者之间发生交互抗性的话,会严重影响可持续害虫治理策略的研发。针对两大类杀虫剂,昆虫的适应机制可能存在着很大的不同。本文综述了昆虫对植物源化感物质的抗性,重点是讨论其分子基础和代谢代价。

Currently, plant-derived insecticides and chemical pesticides are concurrently applied in cultured lands. In a specific agroecosystem, the pests will experience the two selection pressures during their lives. If cross-resistance occurs between these two types of substances, then the development of sustainable pest management strategies will be more and more difficult in the future. Insect pests may adapt to these substances differently. In this paper, we reviewed the resistance of insects to plant allelochemicals as well as the possible cross-resistance between plant allelochemicals and chemical pesticides, and make an emphasis on their molecular basis and detoxification costs.
