Abstract


In Transylvania, the evolution of wheat insect pests is strongly influenced by the ecotehnological conditions, by climate change and current technology (Malschi, 2009 Malschi et al., 2015). The paper presents the dynamics and importance of the main pests of wheat (thrips, aphids, leafhoppers, wheat flies, cereals sunbugs, investigated under the integrated pest control system suitable of the area. During 2015-2016, the investigations were conducted at the Agricultural Research and Development Station Turda, from the wheat no tillage cultural system with cereal rotation of three years and applying all zonal recommendations of technology and phytosanitary complex. The pest monitoring was performed based on the samples collected with entomological net, by decadal 100 sweep-net catches/sample. The study data shows the danger of the attack of abundant populations of wheat flies (Phorbia securis, Delia coarctata, Opomyza florum, Oscinella frit etc.; wheat fleas (Chaetocnema aridula) and cereal leaf beetle (Oulema melanopa); leafhoppers (Psammotettix alienus, Javesella pellucida, Macrosteles laevis); aphids (Sitobion avenae, Schizaphis graminum, Rhopalosiphum padi); thrips (Haplothrips tritici), sunbugs (Eurygaster maura, Aelia acuminata) etc., and the necessity of applying insecticide treatments on the vegetation.

Since 2015, a stronger impact of global warming on the wheat pests structure (%) are found. This change began on the last ten years. The importance of cereal sunbugs is increasing, well as the importance of the wheat flies, aphids and leafhoppers, which requires professional study on the pest dynamics and adequate integrated control of wheat pests.
