Pollinator parasites
Biodiversity, impact and control of microsporidia in bumble bee (Bombus spp.) pollinators

Bumble bee rearing for pollination is a necessary tool for farming of many crops.
In spite of observations of microsporidian infections in 14 different bumble bee
species, only one microsporidium, Nosema bombi, has been described from bumble
bees. For

Objectives
i) to document incidence in microsporidian infections in the field and in
commercial bumble bee colonies
ii) to document Microsporidia diversity in bumble bees
iii) to investigate parasite biology, cross infectivity and modes of transmission
iv) to det

Progress to Date
The project has started as anticipated. Field collections of bumble bees are ongoing with subsequent analysis of collected material. Infection experiments with Microsporidia across host species have been initiated.
Micropsporidia infections have been detected in several different bumble bee spp. Nosema bombi has been confirmed from Bombus terrestris in Switzerland, Sweden and The Netherlands. As yet unidentified Microsporidia has also been found in other host spp., which is pending further analysis.
