PL PATH 514  INSECT VECTOR OF PLANT VIRUSES AND OTHER PATHOGENS                                         (1L+1P)III

Objective
Provide knowledge on transmission of viruses by vectors, their biological & molecular interaction and management

Theory

UNIT I
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.

UNIT II
Transmission of plant viruses and fungal pathogens. Relation between viruses and their vectors.

UNIT III
Transmission of plant viruses by aphids, whiteflies, mealy bugs and thrips.

UNIT IV
Transmission of mycoplasma and bacteria by leaf hoppers and plant hoppers.

UNIT V
Transmission of plant viruses by psyllids, beetles and mites. Epidemiology and management of insect transmitted diseases through vector management.

Practicals
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.
