Abstract:

The electrical penetration graph (EPG) technology is more and more widely used in studying piercing sucking insects, such as aphid, whitefly, leafhopper and thrips. Especially for aphid and whitefly, it has been adopted to study host speciality, plant resistance and virus transmission. We reviewed the research progress and application prospects of EPG through examples of typical piercing sucking insects.

 

Key words: Piercing sucking insect, EPG, aphid, whitefly, host speciality, virus transmission, plant resistance
