Title

Association Between Density of Foraging Bees and Fruit Set in Commercial Fields of Rabbiteye Blueberries (Ericales: Ericaceae) in Louisiana and Mississippi

Robert G Danka; Blair J Sampson; José D Villa Journal of Economic Entomology 2019. doi:10.1093/jee/toz005

Other claims from this paper (7)

Association Forager density had inconsistent effects on fruit set across the study.
Association In 2001, H. laboriosa was associated with increased fruit set.
Association In 2001, Bombus was associated with increased fruit set.
Association A. mellifera made a weaker contribution to fruit set in 2001.
Observation H. laboriosa populations were more consistent across sites than other bees.
Intervention effect Supplemental A. mellifera did not increase forager density in stocked fields.
Intervention effect Supplemental A. mellifera did not increase fruit set in stocked fields.
