This document discusses several common insect pests that affect brinjal crops, including their symptoms, identification, and damage. The main pests covered are the stem borer (Euzophera perticella), which causes young plants to droop and stunts older plants; the bud worm (Scrobipalpa blapsigona), which shrivels and sheds flower buds; the hadda or spotted beetle (H.vigintioito punctata), which scrapes chlorophyll and skeletonizes leaves; ash weevils (Myllocerus species), whose grubs feed on roots causing wilting; and the lace wing bug (Urentius hystricellus), which yellows
