Wild natural hedges provide a habitat to many animal species, prevent the erosion of soil and serve as a shelterbelt, and may also play a role in reducing the drift of plant protection agents. They are of great importance for natural enemies (antagonists) because they provide them with a source of food, as well as a place to overwinter and reproduce. The objective of this research project was to determine the population of beneficial arthropods on wild woody plants (wild hedges), for the purpose of implementing conservative biological control methods. The research was conducted between early May and late August at two localities in the Zadar County. Samples were collected by applying the beating method with the help of the entomological network, every 8 to 12 days. In total, 472 samples of beneficial insects were collected at both localities. The greater part of these samples belonged to Aranea order (260). The most numerous insect families were Coccinellidae (51) and Cantharidae (47). The plant species that attracted the greatest number of beneficial arthropods were: Rosa canina L. (13.14%), Paliurus spina-christi Mill. (11.65%), Pistacia terebinthus L. (11.65%), Rubus fruticosus L. (10.59%) and Lonicera implexa Aiton. (10.17%). Results show that the ecological infrastructure – that is, in this case, wild woody plant species – play an important role in attracting beneficial arthropods, and thus represent an important factor in preserving biodiversity within agricultural ecosystems and contribute to the conservative biological control method.
