摘　　要：转基因作物的商业化释放为目标害虫的抗性进化和非靶标生物的种群质量提供了高强度的选择压力，而波动性不对称（ＦＡ）的水平可用来指示某一种群对这种环境压力的进化和适应能力。ＦＡ方法比常规的生活史参数更加灵敏，而且可将环境压力的影响定量化，同时其测定和分析都比较简单，不需要昂贵的设备和试剂，使研究和监测成本大大降低。因此，ＦＡ是一种方便易用、经济快捷的生物监测工具，可作为转基因植物所造成的生态压力的早期预警指标。本文综述了国外进化生态学研究中有关ＦＡ的进展及在我国开展ＦＡ研究的科学意义和应用前景。Transgenic plants provide a strong stress to the target and non-target pests and profit insects, an useful indicator of these stress is fluctuating asymmetry (FA). FA, as an ecological monitor, will be more sensitive than traditional parameters of life history and be able to quantitate the impact of environmental stress. Furthermore, the FA measures and analysis is very simple and cheap. So FA could be introduced to the risk assessment of transgenic plants as an earlier warning index. The advances of FA studies in western countries and the scientific significance and application prospects of FA research in China were reviewed.
