Biodiversity evaluation of insect community is strongly influenced by used sampling method. We applied five methods (photocelectors, soil traps, shaking down, yellow dishes in low and high position) in three localities of Northern Bohemia in The birch forest at the same time and we compared quantitative and qualitative properties of heteropteran taxocoenosis. Qualitatively similar samples of communities were obtained from the photocelector method and soil traps with the dominance of epigeic species and, further, from the methods of shaking down and yellow dishes. The effectivity of sampling methods was assessed using the rarefaction method revealing a high heteropteran species richness obtained by yellow dishes as compared with abundant samples from shaking down and photocelectors. Biodiversity measures depend on the sampling method, the lowest were in the samples collected by shaking down, while the highest species diversity was recorded in the sample from yellow dishes. For a complex species richness and heterogeneity determination of true bug communities, even non-specialised methods for heteropterans sampling should be used.
