These bumble bees are reared commercially and they are important pollinators of greenhouse tomatoes and blueberries, with research showing positive correlations between the density of common eastern bumble bees and blueberry fruit set as well as the number of large seeds per berry up to 150 m from the hive. Of the three commercially available pollinators of Maine blueberries - honey bees (Apis mellifera), alfalfa leafcutter bees (Megachile rotundata), and common eastern bumble bees (Bombus impatiens) - the common eastern bumble bee may be the most efficient pollinator. It pollinates flowers faster than and at cooler temperatures than honey and alfalfa leafcutter bees and is more faithful to the blueberry crop, even if alternate forage is available. Additionally, common eastern bumble bees will fly in moderate rain. The common eastern bumble bee is at least two to 10 times more efficient at pollinating blueberry than one honey bee. However, common eastern bumble bee colonies are more expensive to use than honey and alfalfa leafcutter bees because they can be used during only one season. These bees are also important pollinators of prairie ecosystems, preferring to forage on Culver's root (Veronicastrum virginicum) but also pollinating wild bergamot (Monarda fistulosa) and aster (Asteraceae) in late summer.
