Abstract: Elaborated in 2008-2011, at Agricultural Research Station Turda, the paper presents the research concerning the increasing of main wheat pests abundance and extension risk of pests attack on the agro-ecological changes in Transylvania. Entomological study has been carried out under different cultural soil technologies: classical (by plowing) and conservative (by minimum soil tillage and no tillage), in open field agroecosystems with antierosional terraces and in agroforestry belts farming system. The spring months of the last years was characterized by an increased warming and dryness periods, causing the pest abundance and damages growth on wheat. It was pointed out major outbreaks of attack of thrips (Haplothrips tritici); wheat flies (Chloropidae: Oscinella frit, Meromyza nigriventris, Elachiptera cornuta etc. and Anthomyidae: Delia coarctata, Phorbia securis, Ph. penicillifera); stem flea beetles (Chaetocnema aridula); bugs (Eurygaster maura, Aelia acuminata), leafhoppers (Javesella pellucida, Psammotettix alienus, Macrosteles laevis), aphids (Sitobion avenae, Schizaphis graminum, Rhopalosiphum padi, Metopolophium dirhodum) etc. The research results prouved the importance of integrated pests control and insecticide applications in two different moments: end of tillering phase and spike appearance, in open field with classical soil technology. Also, the integrated pests management (IPM) is a major section of soil no tillage technologies comprising a special pest control strategy, with insecticides application in 2-3 succesive treatments, entomophagous conservation and use, environmental protection. The IPM research pointed out the efficiency of biological control, only using the entomophagous natural resources, without insecticides application, in the farming system with protective agro-forestry belts – favorable for the increasing of useful fauna.
Key words: wheat pests, entomophagous, integrated pest control, soil no tillage technology, protective agroforestry belts.
