Government conclusion
For the , the Gypsy Cuckoo Bumble-bee ( Bombus bohemicus) is actually reviewed because of the Panel to your Reputation away from Threatened Creatures inside Canada (COSEWIC) because Threatened, because of a huge (>50%) inferred decrease in variety across the earlier several years, mostly when you look at the southern Canada. It was put in Agenda 1 of the Variety at stake Operate (SARA) when you look at the .
The latest Gypsy Cuckoo Bumble-bee are a professional colony parasite; it just targets new nests out of bumble bee varieties during the subgenus Bombus. Its erica would be attributed straight to high refuses within the about three of them servers varieties: the Rusty?patched Bumble-bee ( B. affinis), the fresh new Purple-banded Bumble bee ( B. terricola), and also the Western Bumble bee ( B. occidentalis).
The newest four fundamental risks affecting the new Gypsy Cuckoo Bumble-bee is actually: absolute system modifications (we.e., this new refuses of the machine bees); pathogen alert and you may spillover off managed bumble-bee communities for the greenhouses, and to a lesser the quantity of Honey Bees (mediated mostly as a consequence of loss in host bees); pollution (the use of pesticides, herbicides and you will fungicides during the agriculture and you will silviculture); and you will climate alter (habitat moving forward and you can modification, temperature extremes). Intensification off agriculture, and metropolitan/suburban and commercial development may worsen regional impacts otherwise blend in order to produce cumulatively bad has an effect on over more substantial scalepetition with Honey Bees and you will escaped populations out of handled bumble bees can be a beneficial danger in a number of elements. A few of these risks act generally to the machines of one’s Gypsy Cuckoo Bumble bee, but also act directly on new bee itself.
The new Gypsy Cuckoo Bumble bee are definitely restricted to the brand new densities of the servers; the servers subsequently need a constant package of floral tips to help with colony growth: pollen and you may nectar must be readily available regarding growing season. Bumble bees keeps a form of genetic intercourse devotion that makes them extremely subject to extinction whenever productive inhabitants products is small.
