Research Area:

Integrated pest management (IPM), biological control of arthropod pests, pesticides efficacy and their effect on natural enemies, biology and life history of arthropod pests.

Description of Research:

Research activities involve studies on biological control of arthropod pests, natural enemy phenology, use of herbivore induced plant volatiles (HIPV’s) as a natural enemy monitoring method, pesticides efficacy and their sublethal effect on natural enemies, biology and life history.
