植物病毒大都由介体昆虫传播,该传播过程并非简单地携带和制造侵染伤口,而是具有一定的特异性,即某种病毒只能由某种或某几种昆虫传播,而某种昆虫只能传播某种或某几种病毒。根据昆虫传播的特点又将传播分为持久性传播和非持久性传播等。因此,介体昆虫在获毒和传毒过程中涉 Plant viruses are mostly transmitted by mediator insects, which do not simply carry and create invasive wounds, but have a certain specificity that certain viruses can only be transmitted by one or more insects, Can spread one or several viruses. According to the characteristics of insect transmission in turn disseminated into persistent and non-persistent transmission and so on.
