Abstract: Heteroptera are a monophyletic group of insects classified in the Hemiptera order. They are distinguished by the varied construction of the wings of the first and second pair, the stingily-sucking mouthpiece and the presence of the gula on the ventral side of the head. Most of the comprehensive work which analyzes the composition of Heteroptera species in plant communities refers to protected areas. There are a few studies focusing on the true bugs fauna within agricultural areas. These areas include the Trzebnickie Hills, which form a range of stacked terminal glacial moraine, which constitute the mesoregion that is the central part of the Trzebnicki Shaft. The morphological and topoclimatic diversity of the Trzebnickie Hills area makes the vegetation varied and well sunlit slopes are used for orchard and vegetable cultivation. This area has been explored in terms of heteropterofauna only fragmentarily, which was the basis for conducting a faunistic study of it. Research of terrestrial true bugs fauna was conducted in 2012-2014, on 23 research plots in the area of the municipalities of Oborniki Śląskie, Trzebnica and Wisznia Mała. Several methods have been applied to the collection of true bugs, the most effective of which has beed found to be the bucket. To analyze the collected research material, indicators of species diversity have been used, as well as comparative analysis of clusters of true bugs inhabiting different areas and ecological and chorological analysis. The material collected in the Trzebnickie Hills was designated to 188 species of terrestrial Heteroptera, belonging to 16 families and 118 genera. In total, one new species for the fauna of Poland – Psallus albicinctus and 128 new species for the fauna of the Trzebnickie Hills have been shown. The trophic analysis showed a similar proportion of polyphagous species to mono- and oligophagous species. On the other hand, the chorological analysis showed that the palearctic, eurosyberian and western-palearctic elements were the most represented ones. Based on the analyses, two main groups of true bugs communities associated with selected phytocoenosis were identified. In addition, in the landscape dominated by agrocenoses, an increased number of pests has been observed.
