The field experiment was conducted to study the management package for sucking pest under high density planting system in cotton during winter 2018-2019 (August 2018 to January 2019) and summer 2019 (February to July) at Cotton Research Station, Srivilliputtur. The results revealed that mean population of sucking pests viz., leafhopper, thrips, whitefly and number of whitefly per traps was minimum (4.00 and 1.09 /3leaves;1.52 and 1.38 /3leaves;1.44 and 0.84 /3leaves and 13.88 and 12.40/traps) and yield was high (18.65 and 17.53 q/ha) q/ha) in treatment (T5) of ST with Beaveria bassisana @ 10 g/kg of seed + soil application of neem cake @ 250 kg/ha + yellow sticky trap @ 40 nos./acre + release of green lacewing @ 1 lakh eggs/ha at 30 DAS + need based spray of Dinotefuran 20 % SG@ 150 g/ha or Flonicamid 50% WG @ 150 g/ha or azadirachtin 10000ppm @ 1 lit./ha on 20,35,50, and 65 DAS followed by T4 (16.54 q/ha and 15.44q/ha), T2 (16.50 q/ha and 15.95 q/ha) and compared to untreated check (10.98q/ha and 10.65 q/ha) and BCR (3.01 and 2.89) under high density planting system on cotton (HDPS).
