摘要:

植物病毒可以对寄主植物造成危害,也可以对寄主植物增益;植物病毒的侵染可以对节肢动物及其天敌造成生态适应性、生长发育特性和行为特征的改变;植物病毒与介体节肢动物、非介体节肢动物、介体天敌及其他病原微生物间也存在相互作用。对外来物种进行风险评估是预防生物入侵的重要手段,明晰植物病毒侵染对寄主所在生态系统造成影响的各类生物因子及其相互作用关系,是开展植物病毒侵染所造成生态风险评估的研究基础。对植物病毒侵染寄主植株后,对寄主及寄主周边的介体节肢动物、非介体节肢动物、介体天敌,以及病原微生物等各类生物因子的影响及相互作用关系进行了综述,并从入侵生态学及植物病毒生态学的角度,探讨了植物病毒生态学未来的研究方向。以期为植物病毒入侵某一生态系统后所产生的生态风险评估奠定研究基础,并为植物病毒病的防控提供科学依据。

Abstract:

Plant virus can harm or gain host plants,and plant virus infection can change the ecological adaptability,growth and development characteristics and behavior characteristics of arthropods and their natural enemies. There are interactions between plant viruses and vector-arthropods,non-vector arthropods,vector natural enemies,other pathogenic microorganisms. Risk assessment is an important means to prevent the invasion of alien species. Clarifying the various biological factors and their interactive relations that affect the host ecosystem is the research basis of ecological risk assessment caused by plant virus infection. Here we make an overview on the interactive relationships among the plant viruses and the host plant,vector-arthropods,non-vector arthropods,vector natural enemies,other pathogenic microorganisms etc. We also discuss the future research directions of plant virus ecology on the perspectives of invasion ecology and plant virus ecology,aiming at providing an important study basis for the ecological risk assessment after plant virus invades an ecosystem as well as the control and prevention of plant virus disease.

Key words: plant virus, ecosystems, biological factors, interactions, risk assessment
