Sažetak
In a study in three European countries (Germany, Croatia and Serbia) oilseed rape is cultivated with different management methods: conventional and integrated cultivation and organic farming. The impact of the management methods on diversity and abundance of soil organisms is studied. Methods for recording the soil animals are pitfall traps, emergence traps, endogaeic pitfall traps and yellow water traps. Among the predators especially the ground beetles (Carabidae), rove beetles (Staphylinidae) and spiders (Arachnida) are evaluated. To asses the impact of the decomposers, the earthworms are collected and their weight, abundance and diversity in the cultivation systems will be compared. At the field margins of the treatments with integrated cultivation and organic farming a trap crop strip with turnip rape is drilled to attract pests of oilseed rape plants. To evaluate its effectiveness as traps crop pest insects are collected and the abundance in the treatments is studied. First results with pitfall traps (10.9.10-12.1.11) show that larvae of Carabidae are more active in the fields with organic farming than in the other treatments. The numbers of the pest cabbage stem flea beetle (Psylloides chrysocephala) is distinctly higher in the trap crop strips with turnip rape than in the oilseed rape plots. This result confirms the high attraction of turnip rape in order to protect oilseed rape crop plants from pest infestation.
