Different insecticides for the control of walnut husk fly Rhagoletis completa Cresson has been evaluated in the walnut collection in Maribor in year 2006. In the trial we tested four different insecticides (Perfektion, Laser, Decis, and Proteus) and two combinations of insecticides (Perfektion + Nu Lure and Laser + Nu Lure). We treated whole walnut trees or only the inferior third part of the trees. In the untreated control the percent of the infested nuts was 57.7 %. In the treated plots the lower percentage of infested nuts was recorded on trees treated with Proteus (20.0 %), 21.3 % of infested nuts was recorded in combination of Laser and Nu Lure and 23.3% on the tress treated with Perfektion + Nu Lure and with Perfection.
