摘　　要：转基因抗虫作物的商业化种植带来了显著的经济、生态和社会效益,对转基因抗虫作物的安全性评价也一直是国内外学者研究的热点。对生物非靶标效应的研究是转基因抗虫作物安全性评价的重要组成部分,农田天敌类生物是其中的重点内容之一。瓢虫是农田生态系统重要的捕食性天敌,评价其在转基因抗虫作物田间是否能通过捕食猎物或取食花粉而接触到杀虫蛋白并富集于体内,进而对自身产生一定的非靶标效应,这对捕食性瓢虫的安全性研究具有重要的意义。本文从捕食性天敌瓢虫的生命表参数、行为功能参数、田间群落参数及体内微环境指标等方面综述了转基因抗虫作物对瓢虫的安全性研究进展,并对后期转基因抗虫作物对田间捕食性天敌的研究方向提出了建议,以期为转基因抗虫作物的环境安全性研究提供理论指导和为进一步完善转基因抗虫作物对瓢虫安全性评价的技术体系提供系统的数据资料。The commercial planting of insect-resistant genetically modified(IRGM) crops has greatly benefited the economy,ecology and society.Risk assessment of IRGM crops has been a focus of researchers worldwide.A new IRGM variety must be subjected to a rigorous pre-market risk assessment before it is commercially grown,and an evaluation of potential adverse effects on valued non-target organisms is an important part of the risk assessment process.Ladybugs are dominant non-target predators in agroecosystems,and their chronic exposure to Bt proteins when feeding on pollen or preying on other insects in IRGM crops can lead to environmental risk.Thus,evaluating the potential adverse effects of IRGM crops on ladybugs is of great importance.Here,we reviewed the progress on assessing the ecological effects of IRGM crops on predatory ladybugs based on life table,behavioral function,field community,and internal microenvironment parameters.We have put forward suggestions for future research on assessing the risk of IRGM crops on the predators.Our paper could provide technical support and an experimental basis for developing a risk assessment of IRGM crops.
