The percentage of fruit set from flowers did not differ significantly between the two tomato varieties (χ 2  = 2.405, df = 1, P  = 0.121), and both varieties set a larger percentage of fruit when bee pollinated. Because tomatoes require only minor agitation to set fruit, the simple act of bumble bee visitation and pollen foraging produces a subtle increase in fruit yield, which is important on a commercial scale. Fruit pollinated by bees ripened on average 2.88 d faster than nonpollinated, control fruit ( Fig. 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 ). Williams The response to bee visits differed between the two tomato varieties, with Favorita showing significant responses while the Sungold variety did not. . R. Usually nests underground. Hives average 50-250 individuals, with a queen who lays the eggs, callows which are the newly emerged adults, nurses who tend the hive and are confined to the nest, … . I. 100 Bombus huntii (cat.) Washitani Cameron Favourite flowers include; milkweeds, currants, goldenrod, rhododendron. IUCN. Common. 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. Bombus huntii is a species of bumblebee.It is native to western North America, where it occurs in western Canada and the United States as far east as Manitoba and Minnesota, and in Mexico as far south as the Trans-Mexican Volcanic Belt. . Despite these ambient levels of movement in the greenhouse, bumble bees significantly contributed to the pollination of one variety of tomato in the first experiment and another variety in the larger second experiment in the present study. Bombus huntii has been noted for its wide distribution in the West (Koch et al. In the second round of pollination, the open-bagged fruit of the Favorita plants were significantly heavier and had a larger diameter than those in closed bags. J. D. In fact, direct comparisons of bumble bee species for efficacy in pollinating tomatoes has not been conducted outside of Japan ( Asada and Ono 1996 ). Body lengths - queen 18 - 20 mm, worker 8 - 17 mm, male 10 - 15 mm. Evison J. P. Solter Hughes Tweet; Description: Bumblebees are social insects that are characterised by black and yellow body hairs, often in bands.

Can be confused with B. rufocinctus, B. huntii, and B. bifarius. 2011 ), Bombus occidentalis Greene, which until the early 2000s was the primary native bumble bee used for commercial pollination in North America ( Velthius and van Doorn 2006 ). Nests underground. In the second experiment comparing all three bumble bee species, fruit weight was an average of 25.2 g heavier per fruit pollinated by bees versus the control, and the number of days to harvest was 2.9 d shorter for bee-pollinated fruit. Pollination by any of the three bumble bee species resulted in significantly heavier fruit than the control of no pollination ( Fig. . pdf,,, Receive exclusive offers and updates from Oxford Academic, Copyright © 2020 Entomological Society of America. Winston Whittington Források. 2012 ) to replace B. impatiens in western Canada, the western United States, and Mexico. 2006 , Inoue et al. 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. In neither of the two direct comparisons did B. huntii result in significantly different fruit weight than B. impatiens ( P  = 0.174 and 0.145). P. H. H. W. Uncommon. Three bumble bee species were compared with a control that received only ambient air movement. Nests underground. Often forages from red flowers, and nectar robs hummingbird pollinated flowers. Body lengths, queens 14 - 18 mm, workers 10 - 14 mm, males 10 - 13 mm. Koch Significance is at the P  < 0.05 level, and bars with the same letter are not significantly different. Data were logarithmically transformed and significance was set at α < 0.05 for all tests. 112 Bombus insularis (cat.) Worldwide, tomato production is the primary use for commercial bumble bees, and several species have been used with success ( Velthius and van Doorn 2006 ). A. Bombus huntii foraging on Echinacea. James P. Strange, Bombus huntii , Bombus impatiens , and Bombus vosnesenskii (Hymenoptera: Apidae) Pollinate Greenhouse-Grown Tomatoes in Western North America , Journal of Economic Entomology, Volume 108, Issue 3, June 2015, Pages 873–879, Fruit diameter was measured with a Sylvac Ultra Cal II digital caliper (Crissier, Switzerland) at the minimal and maximal equatorial points and averaged. 8 Bumble Bees of the Western United States Diet Bumble bees are generalist foragers, feeding on a diverse suite of pollen and nectar resources. Medium tongue length. Orange-belted Bumblebee - Bombus ternarius. Medan Description. J. P. Hair short to medium, but shaggy and uneven. . Thomson Surely one of the most handsome bumble bees anywhere, this vibrantly colored bumble is sure to catch your eye. Darvill Despite this, little work has been done to compare the pollination efficacy of potential commercial bumble bee species, with the notable exception of direct comparisons of native Japanese bees to the European B. terrestris in tomato production ( Asada and Ono 1996 ). More than a million colonies are sold worldwide annually to meet pollination needs. F. 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. By contrast, no bees were observed in the closed bags and none of the close-bagged flowers had bite marks, indicating that the exclusions were effective in preventing bee visitations. Regressions were performed to investigate the relationship of measured parameters, and curve estimation was performed to maximize the coefficient of correlation in these relationships. T. L.
