摘要: The effects of broad spectrum and selective insecticides on the structure phytophagous zoophagous communities were investigated in a controlled experiment carried out an apple orchard Hungary. Following cessation intensive use regular application (mainly insect growth regulator compounds) characteristic succession commenced arthropod populations orchards. IPM strategy was developed against arthropods occurring at high population density orchards previously treated with broad-spectrum for many years (e.g Phyllonorycter blancardella, Leucoptera malifoliella, Panonychus ulmi). After pests Stephanitis pyri, Dyasphis devecta, Quadraspidiotus perniciosus increased, thus further improvement program is still required.
