Survival of the pest was significantly higher on Parthenium hysterophorus (80.8%) and cotton (80%) than on Solanum melongena (35.8%). Development duration was significantly lower on cotton (19.9 days) and P. hysterophorus (20.5 days) as compared to egg plant (22.7 days). Body length, width and weight of the pest was maximum on cotton, being 4.66 mm, 2.70 mm and 9.28 mg, respectively.
