Impact of territorial system of ecological stability on stabilizing functions in landscape
 DVOŘÁKOVÁ, Radka
The fields in farming landscape were united to lerge areas in the last 50 years. The balks were ploughed up and their disappearance contributed to the significant loss of biodiversity. Nowadays attepmts are being made to restore the complex agricultural landscape. The creation of territorial system of ecological stability started. Planting biocorridors is a part of this system. Biocorridor is a linear element, consisting of trees and shrubs, which divides large fields. Such non-crop habitats have large positive impact on surrounding landscape. They can also act as refuges for the insect pest. Exapmle is the bird cherry, Prunus padus, a winter host of a cereal pest aphid, Rhopalosiphum padi. In the work the positive and negative effects of TSES are analysed. The important part of the work was to explore, whether the presence of Prunus padus affects the abundance of aphid in adjacent fields. The relatively newly planted biocorridor in Sedlec u Českých Budějovic was used for the work. Based on the results, the suggestions for planting of biocorridors were made, in order to avoid negative effects of spread of this aphid pest species.
