The peak population of mustard aphid on yellow sticky traps was recorded with 35.4±2.9 aphids/trap from 7th SW and it was active from 45th SW to 14th SW, where it was on peak with 712.4±16.4 aphids/plant under the field condition from untreated plots at 3rd SW. Coccinella septempunctatas active from 50th SW to 13th SW of the season and peak population noticed from 5th SW with 14±0.4 grubs and adults/plant. Incidence of mustard sawfly was noticed at early stage of crop from 46th SW to 4th SW and population range was 0.3±0.2 to 7.3±0.6 larvae/plant. Painted bug active two times in a season from 45th – 52nd SW with peak population was 7.5±0.5 nymphs and adults/plant and 6th – 12th SW, where peak population was 8.9±0.5 nymphs and adults/plant.
