Components of ecological infrastructure in vineyard agroecosystems

such as wildflower strips, vineyard edges, vegetation between rows and weed margins in fields play an important role in organic plant production. The composition of weeds as elements of the ecological infrastructure and their influence on abundance and biodiversity of ladybugs was researched in this paper. The present study was conducted from May to October 2011–2012 in the vineyard region of Zadar Northern Dalmatia – Croatia. Ladybugs Coleoptera:

Coccinellidae were sampled by the sweep net method and visual

inspection of plants. A total of 180 individuals of ladybugs were collected during this research. The most abundant species appearing in all localities were Hippodamia variegata Goeze, 1777 41.1 % and Scymnus spp. 23.8 %. Other Coccinellids included Coccinella septempunctata Linnaeus, 1758, Psyllobora vigintiduopunctata Linnaeus, 1758 and Stethorus punctilum Weise, 1891 but

were less presented. Diversity indices varied between sites. The highest value was recorded at the locality Bokanjac 2.41, whereas the lowest was seen at the site Posedarje 1.00. The maximum similarity index 0.90 was recorded between Bokanjac and Suhovare, while the minimum was 0.60 between Bokanjac and Posedarje. Among plants the main weed species hosting ladybugs were Anthemis arvensisLinnaeus, 1753, Daucus carota Linnaeus,

1753, Dittrichia viscose Greuter, 1973 and Chenopodium album Linnaeus, 1753.
