More species occur on fields which are worse invaded by weeds. A total of 43 species were found to occur in the herb layer of shelterbelts. The species encountered on rye were dominants. Maximum density of these leafhoppers varied in different fields from 34 to 243 individuals/m2; densities in shelterbelts - 21 individuals/m2. A shelterhelt affects the distribution of leafhoppers in the field adjacent to it: numbers are lowest at the end of the field near the shelterbelt, and highest at a distance of about 50 m from the latter.}, type={Text}, title={The occurrence of leafhoppers (Homoptera, Auchenorrhyncha) on rye grown near shelterbelts}, URL={http://rcin.org.pl/Content/71169/PDF/WA058_86325_P2840-T18_Eko-Pol-A-Nr-13.pdf}, volume={18}, number={13}, journal={Ekologia Polska}, publisher={PaƄstwowe Wydawnictwo Naukowe}, keywords={Auchenorrhyncha, Secale, crops}, }
