Manager summary
In , the new Gypsy Cuckoo Bumble bee ( Bombus bohemicus) was examined of the Panel on Status out-of Threatened Animals inside the Canada (COSEWIC) because the Threatened, by way of an enormous (>50%) inferred decline in wealth over the prior a decade, generally when you look at the south Canada. It was set in Agenda one of the Species at stake Act (SARA) for the .
The fresh new Gypsy Cuckoo Bumble-bee try a professional nest parasite; it simply purpose the new nests regarding bumble bee varieties during the subgenus Bombus. Their erica would be charged directly to tall refuses in the about three of those server varieties: the fresh new Rusty?patched Bumble-bee ( B. affinis), the fresh Red-banded Bumble bee ( B. terricola), plus the West Bumble-bee ( B. occidentalis).
The new four fundamental threats affecting new Gypsy Cuckoo Bumble-bee try: absolute system modifications (we.elizabeth., the latest declines of their servers bees); pathogen transmission and you may spillover of handled bumble bee populations during the greenhouses, and a lesser extent regarding Honey Bees (mediated generally through losses into the machine bees); contaminants (the application of insecticides, herbicides and you may fungicides into the agriculture and you can silviculture); and you may environment alter (habitat moving forward and you may adjustment, heat extremes). Intensification from agriculture, and you can metropolitan/residential district and you may commercial advancement could possibly get worsen regional has an effect on otherwise merge in order to establish cumulatively negative has an effect on more a bigger scalepetition which have Honey Bees and you can fled populations of handled bumble bees can certainly be an effective issues in a few elements. All of these risks operate mostly for the computers of one’s Gypsy Cuckoo Bumble-bee, as well as act directly on brand new bee in itself.
The newest Gypsy Cuckoo Bumble bee is however simply for the fresh new densities of its servers; their computers subsequently need a reliable package of floral resources to support nest growth: pollen and you may nectar must be readily available on the growing 12 months. Bumble bees features a form of hereditary intercourse determination that renders him or her most subject to extinction when energetic population systems try short.
