Bumblebees are good at learning how to extract pollen from different flowers and can even specialize in certain species. sweet pepper), the damage to the bumble bee population may be much more serious than in a crop that only produces pollen (e.g. With a maintenance-free Bumblebee hive you don't have to be a beekeeper to have the benefits of proper pollination. The solitary queen begins the colony by collecting pollen and forming it into a small lump. Unlike honeybees, bumblebees are attracted to flowers with narrow corolla tubes, such as blueberries and cranberries. Tomato pollen does not loosen easily.

This initial fear is often overcome quickly after working around the mild mannered bumble bee species that have been selected by breeders. Others rear bumble bees to learn more about the different species for scientific reasons, as there are vast gaps in our knowledge of the biology of most bumble bee species. Systemic pesticides (pesticides that are absorbed through the roots) often have a long-lasting residual effect. If a flower produces nectar in addition to pollen (e.g. Some flowers self-pollinate (pollen moves to a flower on the same plant, perhaps even the same flower where it was produced).

Once the first brood develops, they take over all the colony duties except egg laying. Introduction schedule It is recomended that you time the introduction of the first hive with the expected opening of the first blossoms in the crop. Bumble bees are reared commercially for shipment to growers especially for greenhouse grown crops such as tomatoes which require "assistance" with pollination. Bumble bees and honey bees are not necessarily interchangeable as pollinators for some plant species. Direct effects occur when worker bees and larvae die as a result of contact with or digestion of a chemical product, and indirect effects occur when the smell of the treated flower puts off the bumble bees, causing visits to stop.
