Pollination of Greenhouse Tomatoes by the North American Bombus vosnesenskii (Hymenoptera: Apidae)
TLDR
The results show that B. vosnesenskii is an effective pollinator of tomatoes in greenhouses and produces larger fruit than non-bumble bee-pollinated flowers. Expand
Behavior of bumble bee pollinators of Aralia hispida Vent. (Araliaceae)
TLDR
The andromonoecious plant Aralia hispida has a complicated blooming schedule involving alternations between male and female phases and the major pollinators, bumble bees, show several characteristic behaviors in response to the plant's presentation. Expand
THE EVOLUTIONARY SIGNIFICANCE OF BUMBLE BEE COLOR PATTERNS: A MIMETIC INTERPRETATION
  • R. Plowright, R. Owen
  • Biology, Medicine
  • Evolution; international journal of organic…
  • 1 July 1980
TLDR
It is argued that Miillerian mimicry not only provides a parsimonious explanation for the striking color resemblances between members of sympatric, though taxonomically heterogeneous, groups, but also furnishes a satisfactory resolution of a long-standing controversy concerning color convergences between parasitic bumble bees and their hosts. Expand
Flower handling by bumblebees: a comparison of specialists and generalists
TLDR
Naive workers of the specialist bumblebee, Bombus consobrinus, were more efficient than those of generalist species in acquiring flower-handling skills on their specialty plant, Aconitum (monkshood). Expand
Rearing Bumble Bee Colonies in Captivity
TLDR
Three methods were used to induce the following Bombus species to start colonies in captivity: B. rufocinctus, B. nevadensis and B. terricola, and moderately successful results for B. perplexus, b. Expand
Mortality rates of adult bumble bee workers (Hymenoptera: Apidae)
Survivorship data were obtained for a cohort of 274 individually marked workers of the bumble bee Bombus terricola Kirby. The mortality rate was very nearly constant for the first 14 days of adultExpand
Pollen carryover, nectar rewards, and pollinator behavior with special reference to Diervilla lonicera
TLDR
In Diervilla lonicera, bees desposited significantly more grains on flowers which contained large amounts of nectar than on drained flowers, and the implications are discussed in terms of plant strategies for optimizing pollination. Expand
Worker-queen conflict and male parentage in bumble bees
TLDR
Male production by workers appears to be a manifestation of worker-queen conflict and the workers do not seem to be in ‘control’ in the colonies. Expand
