 abstract={The four trophic groups found in the agricultural landscape of Great Poland include: zoophages – 12, zoo-phytophages – 16, phytophages – 46, and saprophages – 2 species. In potato and rye plantations, and in the shelterbelt herb-layer the specific composition of these trophic groups, and the dominant species in particular, are similar. In spring and in summer, after the harvest season, the numbers of the particular associations are under the influence of migration phenomena. The richest and most abundant are the bug associations in potato plantations, where the post-harvest migrations from cereal fields restore the fauna destroyed by pesticides. The abundance of cropfield Heteroptera is affected by the shelterbelts.},
