Nematodes That Transmit Plant Pathogenic Viruses

Abstract

Nematodes (nematodes) are worms of Kingdom: Animalia, Phylum: Nematode, the second largest group after insects in terms of number and diversity, and does not have a respiratory and circulatory system but They contain a pseudo body cavity and are found in all humid environments in the world and their parasitic species are not visible to the naked eye. So far, more than 4100 species of plant-parasitic nematodes are known, belonging to about 200 genera to more than 30 families. However, the types that transmit viruses do not constitute more than 1% of the number of parasitic nematodes on plants. The mouth parts of nematodes that transmit viruses, represented by the Stylet, are the body structures important in transmitting viruses, and the shaft is usually elongated. Which enables it to feed deeply inside the root of the plant.
