GMW conducts field and semi-field studies on pollinators: honeybees (“Apis mellifera”) and Bumbles bees ( “Bombus terrestris”), in greenhouses following the latest EPPO, CEB and OECD guidelines.
The studies are all conducted in Spain following GLP standards.
We design and conduct studies to assess the general effects of plant protection products on bees or to investigate more specific questions such as the impact on brood development in honey bee colonies exposed to treatments as well as the long-term development of exposed colonies.
- Semi-field tunnels studies
- Field studies
- Bumble bee (“Bombus terrestris”) studies are carried out under greenhouse conditions
For standard field studies we perform trials on Phacelia or on other relevant crops at different locations in Spain. During the study, several para- meters such as flight activity in the crop, mortality of the bees in the crop (linen sheets) and in front of the hives (dead bee traps) as well as the condi- tions of the colonies and brood development are recorded. In addition to general parameters, we offer detailed observation on the bee behavior, long-term observation of bee colonies (including over-wintering success) and residue samplings of all kinds of matrices of the bee hive and/or the crop.
BUMBLE BEE (“BOMBUS TERRESTRIS”) STUDIES ARE CARRIED OUT UNDER GREENHOUSE CONDITIONS
We offer tailor-made specific studies to investigate the pollination efficiency of bumble bees inside a greenhouse, combined with their exposure to plant protection products.
In addition we can include residue samplings from foraging bumble bees for pollen collection and flowers.
