Analyses of interactions between the landscape and natural pear psylla antagonist - Results of a study at the German fruit growing region "Lake Constance"

In order to study the influences of the landscape on orchards pests, the areas around pear orchards were investigated. An inventory of landscape elements was made and presence and quantity of natural enemies was assessed. Data were analysed to whether the quantity of small landscape elements and land use were correlated with the quantity of pests or natural enemies. The study was conducted in different European regions within the Network of Excellence ENDURE (European Network for Durable Exploitation of Crop Protection Strategies). Results of the studies are intended to be used to optimise integrated pest management. Results from the Lake Constance region are presented here.
