The objective of this study was to determine the abundance and species composition of thrips recorded on triticum durum in relation to sowing density. The experiment was set up in the Experimental Field Station of Wrocław University of Environmental and Life Sciences, at Pawłowice, Poland, in 2006–2008. It was conducted on triticum durum plants at two different levels of sowing density: 4 and 7 mln seeds per ha. Thrips were observed on plants directly through the whole vegetative season. For identification of species composition insects were collected from ears of plants at the milk maturity stage of grain. The results of performed studies revealed that there was no statistically significant effect of the sowing plant density on the thrips abundance. However, it was found a tendency of increasing number of Thysanoptera, when the plants were sown at 4 mln seeds per ha. During three years of the research, nine species of thrips were identified from Triticum durum. The predominated species were: Haplothrips aculeatus and Limothrips cerealium.
