The purpose of our research has been to determine the complexes of useful insects with trophic specializations of pollinators and melliferous insects, which are present on the flowers of P. tanacetifolia and O. arenaria in the full flowering stage. The taxonomic ratio of the entomofaunal population detected in the two plant species has allowed determining that the insect species of the order Hymenoptera, with 36%, have the maximum share and are followed by Coleoptera – 26%, Hemiptera – 18%, Diptera – 12%, Lepidoptera – 6% and Homoptera with 3% of the total number of identified insect species. The presence of the species Apis mellifera in large numbers has been attested and it confirms the potential of the researched plants as honey plants

Scopul cercetarilor realizate este determinarea complexelor de insecte utile cu specializari trofice de polenizatoris, i meliferi, insecte prezente pe florile de P. tanacetifolias, i O. arenaria în faza de înflorire în masa. Ponderea taxonomica a populat,iei entomofauniste depistate la cele doua specii de plante permite evident,ierea cotei maxime ce revine speciilor de insecte din ordinul Hymenoptera cu 36%, Coleoptera – 26%, Hemiptera – 18%, Diptera – 12%, Lepidoptera – 6%s, i ordinul Homoptera cu 3% din totalul speciilor de insecte identificate. Se atesta prezent,a în numar mare a speciei Apis mellifera, ce confirma potent,ialul melifer al plantelor cercetate.
