Epidemiology of aphid-transmitted plant-virus diseases

Aphids are notorious vectors of plant viruses. This role is facilitated by their method of feeding, by their enormous fecundity, and by their varied migration patterns. There is also a close and fascinating relationship between particular aphid species and the viruses transmitted by them. Aphid reproduction and migration are markedly dependent on weather conditions, and this dependence is very clearly reflected in the epidemiology of aphid-borne viruses.
