Oriental fruit moth Grapholita molesta (Busck) (Lepidoptera: Tortricidae) is the most important peach pest in Brazil. Pest management is based on chemical control using insecticides with high toxicity and low selectivity to natural enemies. Etofemprox (Trebon 100 SC, 100 and 150mL 100L-1), emamectin benzoato (Proclaim 5 SG, 10 and 15g 100L-1) associated to mineral oil (Assist, 250mL 100L-1), metoxyfenozide (Intrepid 240 SC 40 and 60mL 100L-1), spinosad (Tracer 480 SC, 15 and 25mL 100L-1) and fosmet (Imidan 500 PM, 200g 100L-1) were evaluated in laboratory and field conditions to G. molesta control. In laboratory, only etofemprox resulted in low mortality (± 50%) in residual bioassay. In commercial peach orchards, all insecticides reduced pest damage (> 80%). All insecticides shows characteristics for use in the integrated management of G. molesta including low toxicity and reduced application dose.
