Apicoltura 1993; ( 8): 81-97

Insect pollinators of sunflower (Helianthus annuus L.) and phacelia (Phacelia tanacetifolia Benth.) in the Friuli region

On 2 observation dates, the main insect visitors to sunflower were Apis mellifera (68%, 77% of total), 5 Bombus species (27%, 5%) and other bees (5%, 18%; 2 Halictus sp. and one each of Andrena and Xylocopa). On phacelia, the insect populations included rather fewer honey bees (60%, 48%) and more bumble bees (33%, 41%).
