许多昆虫不仅为害农作物,还是植物病毒的重要传播媒介。一般说来,咀嚼式口器的昆虫对传毒并不重要;而同翅目(几乎全是刺吸口器)昆虫,如蚜虫、叶蝉、飞虱、粉虱、木虱、介壳虫等是重要的传毒昆虫。此类昆虫占传毒昆虫的92％以上。例如193种蚜虫可以传播164种病毒;36种叶蝉传播33种病毒;32种飞虱传23种病毒,18种粉虱传5种传毒。其它目的昆虫
Many insects not only harm crops, but also an important vector of plant viruses. In general, insects that chew mouthparts are not important for the transmission of poison; and the Homoptera (almost all thorns) insects such as aphids, leafhoppers, planthoppers, whiteflies, psyllids, scale insects, etc. An important poisoning insect. Such insects accounted for more than 92% of poisoned insects. For example, 193 kinds of aphids can spread 164 kinds of viruses; 36 kinds of leafhoppers spread 33 kinds of viruses; 32 kinds of planthoppers transmitted 23 kinds of viruses, 18 kinds of whitefly transmitted 5 kinds of poisoning.
