Apple blossom thrips (Thysanoptera : Thripidae) is serious pest of apple bloom in some areas of Bandipora and Anantnag of kashmir valley. A field trials were laid out at Dangerpora Kullar, Luckbown (District Anantnag) and Arin and bagh (District Bandipora) in a completely Randomized Block Design during 2015 - 2017. Apple trees of variety “Red Delicious”, 13-16 years of age were selected for the field trial. The highest pest incidence (5-8) thrips per flower was recorded in Madar bandipora. The spraying of the treatments, viz., Thiochloroprid @ 0.3, 0.4 and 0.5 ml/L of water, chlorpyriphos 20 EC @ 0.02%, dimethoate 30 EC @ 0.05% and water as control. The overall bio efficacy of the insecticides evaluated against apple blossom thrip (ABT) was in the order of Code 188 (0.5 ml/L) > chlorpyriphos 20 EC (0.02%) > dimethoate 30 EC (0.05%) > Code thiocloroprid (0.4 ml/L) > thiocloroprid (0.3 ml/L). While comparing the bioefficacy of the treatments on fruit yield (A Grade-fruit boxes / tree), the order of efficacy was thiocloroprid (0.5 ml/L) > dimethoate 30 EC (0.05%) > thiocloroprid (0.4 ml/L) > chlorpyriphos 20 EC (0.02%) > thiocloroprid (0.3 ml/L).
