DEPARTMENT OF ENTOMOLOGY
The department offers Undergraduate ( BS Agriculture) courses and Graduate programs leading to MS and Ph.D degree. The Entomology department has a major research thrust on i) ecological and biological studies of insect pests and their natural enemies, their behavior for insect pest suppression, and management, ii) integrated pest management, iii) biological studies of pollinators and their utilization in vegetable seed production and migratory beekeeping for honey production, iv) environmental toxicology of pesticides and v) collection, identification and preservation of insect pests and natural enemies.
