Mechanisms of Plant Virus Transmission by Homopteran Insects

  • El Desouky Ammar


The great majority of plant viruses and all plant pathogenic mollicutes (Spiroplasma and mycoplasma-like organisms) depend on insects and other arthropods for their natural spread. About 76% of the insect vectors of plant viruses belong to the order Homoptera [15], mainly aphids (Aphididae), leafhoppers (Cicadellidae), plant-hoppers (Delphacidae), whiteflies (Aleyrodidiae), and mealybugs (Pseudococcidae). These insects have piercing and sucking mouthparts which are well suited for acquisition and inoculation of viruses and other “internal” plant pathogens during probing, feeding, and salivation activities on their host plants [6, 7].
