| Abstract | The objective of this study was to determine the abundance and species composition of thrips collected from ears of Triticum durum Desf. in relation to plant protection intensity. The experiment was set up at the Experimental Research Station of Wroc³aw University of Environmental and Life Sciences, at Paw³owice (51o09’ N; 17o06’ E), Poland, in 2006-2008. It was conducted on durum wheat plants at three different levels of plant protection intensity and on common winter wheat plants. The samples of thrips were collected from the ears of the plants at the milk maturity stage of the grain. During three years of the research, eight species of thrips were identified from Triticum durum. Most often the eudominants were Haplothrips aculeatus, Limothrips cerealium and L. denticornis. We have demonstrated that there was no statistically significant effect of the plant protection intensity on the thrips abundance. The host species, on the other hand, did not affect the species composition of the studied insects. |
