Phacelia tanacetifolia and Onobrychis arenaria- attractive plants for pollinating insects

Abstract

The purpose of our research has been to determine the complexes of usefulinsects with trophic specializations of pollinators and melliferous insects, which arepresent on the flowers of P. tanacetifolia and O. arenariain the full flowering stage. Thetaxonomic ratio of the entomofaunal population detected in the two plant species hasallowed determining that the insect species of the order Hymenoptera, with 36%, havethe maximum share and are followed by Coleoptera – 26%, Hemiptera – 18%, Diptera –12%, Lepidoptera – 6% and Homoptera with 3% of the total number of identified insectspecies. The presence of the speciesApis melliferain large numbers has been attestedand it confirms the potential of the researched plants as honey plants.
