Different control measures against the insect pests of bitter gourd (Momordica charantia L.)

Different control measures, viz., M.Y. (Muhammad Yousuf) Strategy (Pressurized water spray), Cultural practice (Picking and burrying of infested fruit) and Diptrex (trichlorfon) as cover and bait spray with Protein hydrolysate were tested for their effectiveness against the insect pests of bitter gourd (Momordica charantia L.) M.Y. Strategy gave better control of whitefly (Bemisia tabaci) as compared with Diptrex and Diptrex plus Protein hydrolysate. In case of melon fruit fly (Bactrocera cucurbitae), Diptrex was the most effective followed by Diptrex plus Protein Hydrolysate and cultural practice but the M.Y. Strategy showed no effect.
