摘要
The role of predators in the integrated protection of agricultural crops is highly important. An example may be found in the use of bird predators for vole control by artificially boosting their aggregations through installation of artificial perches. The dependence of raptor density in the period following nesting (summer through to autumn) on vole abundance in the presence and absence of artificial perches was studied using the method of belt transect. The research was conducted in field biotopes of cultivated sugar beet in the beet-production area of the Olomouc region. Presented research results have revealed that artificial perches installed in sugar beet plantations increase the efficiency of raptor predation pressure on the target pest species up to six times. It is quite obvious that this method of biological control of the common vole may yield significant results in the integrated pest control in sugar beet.
