Abstract

Field experiments on effectiveness of different insecticides against inflorescence thrips, Scirtothrips dorsalis Hood (Thysanoptera: Thripidae) in mango were carried out at Horticulture Farm, Junagadh Agricultural University, Junagadh, India during 2013–14 and 2014–15. All the treatments were significantly superior over untreated check. Results indicated that the maximum reduction of hopper population was recorded in the treatment of spinosad 45 SC (0.13%) and it was statistically at par with acetamiprid 20 SP (0.01%)and carbosulfan 25 EC (0.05%) after third and seventh day of first and second spray in both years. The highest population of thrips per inflorescence found in treatment flubendiamide 480 SC, 0.14% and chlorfenapyr 10 SC (0.0075%).
