Proportion of red clover (Trifolium pratense L.) in pollen forage of Apoidea and Hymenoptera in province of Lublin


, : Proportion of red clover (Trifolium pratense L.) in pollen forage of Apoidea and Hymenoptera in province of Lublin. Pszczelnicze Zeszyty Naukowe 21: 213-217

The pollen loads of 5429 bumble bees and 4695 solitary bees caught on lucerne, red clover and other plants were examined. Red clover pollen constituted at least half of the load in 16 Bombus species, 7 Halictus and 5 Andrena species, and also Anthophora quadrimaculata, Eucera longicornis and Melitta leporina. Negligible quantities of red clover pollen (3-10%) were found on 5 species, only traces on 14 species (including 3 Megachile), and none at all on 23 species.
