Common Name: (Hunt's Bumble Bee) Latin Name: Bombus huntii Greene, 1860 (R. Bercha, det. van Doorn Yokoyama J. D. Fruit was measured with a Sylvac Ultra Cal II digital caliper; pole-to-pole and equatorial diameters were measured three times per fruit and the average for the fruit was recorded. Published by Oxford University Press on behalf of Entomological Society of America 2015. Values are averaged across all four rounds of the experiment. B. Inouye M. L. To commence subsequent rounds of pollination, a week after bees were removed, stems with open flowers were marked with a different color and a new treatment was placed into each bay. Whittington Since the decline of B. occidentalis , the primary bumble bee used throughout North America for greenhouse pollination has been B. impatiens ( Velthius and van Doorn 2006 ). Side Effect Manual . B. huntii workers were observed visiting flowers of both varieties of tomatoes and nearly all the flowers in the open bag treatment were found to have bite marks and bruising on the anther cones (personal observation). L. F. Microbial Control of the Emerald Ash Borer (Coleoptera: Buprestidae) Using, A HRM Assay for Rapid Identification of Members of the Seedcorn Maggot Complex (, Overwintering, Host-Plant Selection, and Insecticide Susceptibility of, Comparison of in Vitro and in Planta Toxicity of Vip3A for Lepidopteran Herbivores, Effect of Chemical Pollution and Parasitism on Heat Tolerance in Dung Beetles (Coleoptera: Scarabaeinae), About the Entomological Society of America, http://www.pollinator.org/PDFs/ BumbleBee.GuideWestern.FINAL. Additionally, fruit weight was shown to be highly correlated to fruit diameter and seed set in all tests and, thus, is shown to be a reliable metric for assessing pollination in future studies. Ono Species descriptions and data provided by: © 2012-2020. There are three species that can easily be confused with B. huntii in Montana: B. ternarius, B. sylvicola, and B. melanopygus. Okada Closed bag clusters were covered by a fine mesh bag to prevent bee entry, while open bags were made of the same material, but only affixed to the cluster stem so as to permit access to the flowers by the bees (to remove cluster handling effect). yellow, T2 and T3: orange, T4: yellow, T5 and T6: black. to allow for the assignment of mature fruit to the appropriate pollination treatment. B. huntii produced significantly heavier fruit than the control in both Rounds 2 and 4 of pollination ( P  = 0.004 and P  < 0.001, respectively). The range encompasses such agricultural regions as the Okanagan Valley of BC, the Columbia Basin and Snake River Plain, the Colorado River Basin, and areas of northern Mexico.

A common name search of Northwestern Sedge matches 'Northwestern Sedge' and 'Northwestern Showy Sedge'. Solter In addition to bruising, bees were observed visiting flowers on open clusters at the commencement of the experiment. Banda 2014. B. Abrahamovich 2007), is native to the intermountain regions of the western United States, Canada, and northern Mexico ( Koch et al. K. Reasons: For now the G5 is an inspection rank based largely on the extensive range of this common western bumblebee. Velthius S. . This work is written by a US Government employee and is in the public domain in the US. of the wings so that the thorax appears dirty or cloudy. The control involved no bees present; however, it did include air movement with ventilation fans and some plant handling by greenhouse workers as in the bays where bees were present.

Williams Washitani Bombus melanopygus is typically found in more forested, montane habitats than those of B. huntii. Like B. huntii , B. impatiens pollination resulted in significantly lighter fruit than B. vosnesenskii in Round 2 ( P  < 0.001) and significantly heavier fruit in Round 4 ( P  = 0.013). Strange Dogterom Colonies were held in the lab and fed sugar syrup and honey bee-collected pollen until 25 workers were present. . 2012 ). Also considered: species of subgenus Pyrobombus are generally stable or increasing. Adams Medler, J.T. Here, two western, Bombus huntii Greene and Bombus vosnesenskii Radoszkowski, and one eastern species, Bombus impatiens Cresson, are compared for their efficacy as pollinators of greenhouse-grown tomatoes. Favourite flowers include, thistles, lupins, Phacelia, Rudbekia, Asters, alliums, roses, apple and cherry blossom, and Penstemon. Investigations into the potential of these species for commercialization are in progress at the Pollinating Insect Research Unit, Logan, UT (J.P.S., unpublished data). Biobest Argentina. Thorp A single stem of each plant was trained to individual guide strings in a V formation. .

In both comparisons of B. vosnesenskii to the control, the species produced no significant increase in fruit weight (Round 3  P  = 0.770; Round 4  P  = 0.792). R. W. Williams J. P. Niwa S. R. Bombus huntii Greene, closely related to B. impatiens and B. vosnesenskii ( Cameron et al. Each bay housed 34 DeRuiter var. on the thorax behind the wings, and yellow hairs laterally on T5. Values that are followed by a symbol are significantly different than values that share the same symbol at the P  < 0.05 level. Ex. The 20-liter, upright, plastic bags contained coconut coir and were watered with nutrient solution uniformly sprayed at intervals throughout the day. M. When plants produced the second full cluster of flowers, clusters on paired plants (in the same bag) were divided randomly into two treatments, close-bagged or open-bagged. When analyzed by round to compare the individual species with each other, the results are more nuanced, as different bee species sometimes produced heavier fruit than other species, depending on the round. R. J. Koch A common species. 2006 , Inoue et al. downloading map data, this may take a minute. Bombus atratus. Three bumble bee species were compared with a control that received only ambient air movement. Y. K. L. F. . Strange >2,500,000 square km (greater than 1,000,000 square miles). L. S. E. F. J. P. Thomson Pollination was monitored by flower bruising on the anther cone until the majority of flowers had been pollinated then the colony was closed and remaining bees returned to the nest box through the one-way entrance. Global Range: (>2,500,000 square km (greater than 1,000,000 square miles)) Not researched in detail but approximately British Columbia to Saskatchewan, south at least to Arizona and New Mexico, east at least to Boulder Colorado in the USA (Kearns and Oilveras, 2009). 2 ), and there were no differences among the three bee species. Miller-Struttmann, N.E. Average fruit weight, fruit diameter, and number of seeds produced in tomatoes pollinated by B. huntii versus an unpollinated control in a greenhouse pollination experiment. B. impatiens is an effective pollinator of tomatoes ( Whittington and Winston 2004 ), yet western native pollinators are now desired. . Flowers that aborted without producing fruit were also counted. P. In two of four comparisons, tomato flowers pollinated by B. huntii resulted in significantly more seed per fruit than those with bumble bees excluded ( Table 1 ). Fruit weight was measured with Denver Instrument APX-1502 balance. Darvill S. Bombus impatiens. R. Curve estimation in a regression analysis of fruit weight to fruit diameter produced a slightly better fit with a quadratic equation ( r2  = 0.959; df = 2,856; P  < 0.001) than with the linear model ( r2  = 0.945; df = 1,857; P  < 0.001). South America. Cameron Both western species performed as well as, or better than, B. impatiens although the differences were nonsignificant overall and varied by round. Note: For many non-migratory species, occurrences are roughly equivalent to populations. Medium tongue length. The present study compares the commercial pollinator, B. impatiens , with two native western North American species B. vosnesenskii and B. huntii as pollinators for greenhouse-grown tomatoes. Colla Across all four weeks of pollination, 860 fruit were harvested and measured, resulting in 162.9 kg of fruit. 2006 , Winter et al. It is the most widespread bumble bee known in Montana. Additionally, the numbers of fruit per cluster and numbers of aborted fruit were examined. S. A. is usually a yellow patch of hairs near the antennal bases. B. huntii and B. vosnesenskii are effective pollinators of tomato flowers in the greenhouse environment equaling the efficiency of B. impatiens in several trials. W. O. H. It is the most widespread bumble bee known in Montana. J. D. 2005. 1 ), indicating that pollination could be assessed without counting seed, a tedious and time-consuming task, but rather by weighing fruit. Mean number of days to the harvest of ripe fruit from the introduction of bumble bees to the flowers. Huang Encyclopedia of Puget Sound is published by the Puget Sound Institute at the UW Tacoma Center for Urban Waters. 2006 , Goulson 2010 , Graystock et al. USDA-ARS, Pollinating Insect Research Unit, 255 BNR, Utah State University, Logan, UT 84322-5310. For example in Round 1 the treatments were control, B. huntii , and B. impatiens and in Round 2 the treatments were B. huntii , B. impatiens , and B. vosnesenskii and so forth through four rounds without repeating any treatment in the same bay twice. Furthermore, in the western United States, some state governments (i.e., California and Oregon) restrict the use of nonnative bumble bees, including the eastern species B. impatiens , in an effort to prevent accidental bumble bee and pathogen introductions. Data were analyzed with a GLM ANOVA with treatment as the fixed effect and round as the random factor.
