History of developments in the area of insects as vectors of plant pathogens. Important insect vectors and their characteristics; mouth parts and feeding processes of important insect vectors. Efficiency of transmission.
Transmission of plant viruses and fungal pathogens. Relation between viruses and their vectors.
Transmission of plant viruses by aphids, whiteflies, mealy bugs and thrips.
Transmission of mycoplasma and bacteria by leaf hoppers and plant hoppers.
Transmission of plant viruses by psyllids, beetles and mites. Epidemiology and management of insect transmitted diseases through vector management.
Identification of common vectors of plant pathogens- aphids, leafhoppers, whiteflies, thrips, beetles, nematodes; culturing and handling of vectors; demonstration of virus transmission through vectors- aphids, leafhoppers and whiteflies.
