Sažetak
Croatia is a little country in the South-East of Europe. The climate in Croatia is continental and mediterranean in the South. Agriculture is the main branch of production. Apple production is one of the most important kinds of fruit production in Croatia. In the apple production we use IPM like other countries in Europe. IPM means using low toxic pesticides and selective pesticides. In this plant protection there is a new problem with insects which was not a problem when we used broad spectrum insecticides. A new problem in the orchard plant protection in Europe is the appearance of phytophagous Heteroptera like Campylomma verbasci, Lygus rugulipennis etc. They damage apple and other fruit species. This problem is very serious because species of Heteroptera are resistand to many insecticide. Our poster presents results of the research over a five-year period, from 1992 to 1996 at several large orchard facilities. In the fauna research we used the visual method and the beating method. We determined the specie for all gathered bugs using determination keys by Stichel, Kelton and Wagner. We wanted to investigate all species of pests, which of them causes the biggest problem, and their domination. We wanted to know if the phytophagous bugs are a problem in modern Croatian orchards or not. In this five-year period we gathered the total of 16,947 samples of insects and bugs. The research included the entire fauna of insects and bugs. During the five-year research on insect fauna we recognized many beneficial Heteroptera from families Anthocoridae, Miridae, Nabidae and Pentatomidae. Our poster shows fauna structure of insects, domination of particular species and the role of bugs in the overall fauna, as well as whether the phytophagous bug species have inflicted any considerable damage to Croatian orchards.
