Abstract: A dramatic decline in the occurrence and diversity of all wild insect pollinator species has been recorded in recent years, including: wild bees, wasps, butterflies and moths, and numerous pollinator species are extinct or threatened with extinction (COM 2018, 395). This is a serious cause for concern because pollinators are an integral part of healthy ecosystems, and the consequences for ecology, society and the economy are incalculable. Changes in land use, intensive agricultural management, excessive use of pesticides, environmental pollution, invasive species, pathogenic organisms and climate change are the main threats to pollinators. The introduction of flower pollinator strips into crop rotations can contribute to the creation of new habitats and encourage an increase in the number and diversity of wild pollinators at both local and landscape level. This practice also favours other beneficial organisms: predatory insects, parasitoids, birds and plants, as both the number of individuals and species increase. This technology can improve soil fertility, overall biodiversity and ecosystem functions, including reducing populations of harmful organisms and weeds. A large number of foreign companies produce seed mixtures for pollinator strips, and their composition depends on the purpose and attractiveness of the selected plant species to the desired groups of insects. Mixtures for biological control are dominated by species from the Apiaceae family, while mixtures with species predominantly from the Fabaceae family are used for pollination ecosystem services. Currently, there are no packaged seed mixtures for pollinator strips on the Serbian market, and the applicability of foreign mixtures in Serbian crop rotations is questionable, because the agro-ecological, technical-technological and social conditions are significantly different. This opens up a great opportunity for launching research programs for modeling this technology for the needs of agro-ecological conditions in Serbia.
