Survey of Bombus species (Hymenoptera: Apidae) near agricultural lands in interior, Alaska. by Rehanon Pampel. MS Thesis University of Alaska Fairbanks, Fairbanks, AK

Bumble bees were collected near farm fields in Fairbanks, Delta Junction and Palmer, Alaska. Delta JUnction displayed the highest relative abundance of bumble bees representing approx. 50% of the overall total bees collected during the 2 year study. The most common bumble bees were B. Centralis, B. frigidus, B. jonellus, M. melanopygus, M. mixtus and B. occidentalis. Bees were found to be infected with Nosema (12%) and nematodes (16.7% although they varied by site. B. occidentalis had the greatest Nosema infection and N. centralis, the greatest nematodes.

Insect visitors and potential pollinators of lingonberries, Vaccinium vitis-idaea subsp. minus, in subarctic Alaska. by Amy Nicole Davis, Patricia S. Holloway and James J. Cruse. Poster presentation.

Fourteen insects were identified as potential pollinators.Species with more than 1000 pollen tetrads per insect included the introduced species: honeybee, Apis mellifera and bumblebee, Bombus terrestris. Native pollinators included the bumblebees Bombus sylvicola and B. flavifrons flavifrons as well as Andrena sp. and Dialictus? (Halictidae). Most insects foraged lingonberry flowers between 0500 (5 A.M.) and 1800 (6 P.M.) despite the nearly 24-hr daylight during anthesis (Table 2). The foraging time of the most important potential pollinators was 0800 – 1800 (8 A.M. – 6 P.M.)
