病毒-植物互作对同翅目媒介昆虫生物学及其传毒机制的影响

Influences of plant virus-plant interactions on biological characteristics and virus transmission mechanism of homopteran vectors

植物病毒会直接或间接地对媒介昆虫造成影响,它既可以感染媒介昆虫从而改变昆虫的生理生化性质,也可以通过侵染寄主植物并改变植物营养成分来影响媒介昆虫.被影响的媒介昆虫表现出某些生物学特性(包括发育、寿命、繁殖力、表现型等)的变化.该文综述了同翅目蚜虫、飞虱和粉虱等媒介昆虫所传播的植物病毒、昆虫对病毒的获取、传播和保留等特性以及媒介昆虫的传毒机制.

Plant virus can affect vectors by invading the body of vector insects directly to change their physiological and bio-chemical indexes or transforming host plants nutrients to influence the feeding vectors, which lead to the changes in the biological characteristics of vector insects, including their development, lifetime, fertility, phenotype, etc. The article reviews the acquisition, transmission and retention of the different plant viruses transmitted by aphids, planthoppers, whiteflies, etc, as well as the mechanisms of virus transmission.
