Project

Support of bumblebees in landscape (TH01030748)

The goal of the project is to support the occurrence of bumblebees in the landscape. It will assess the state of parasitism in the bumblebee populations reared bumblebees, also the effect of probiotic bacteria on bumble...

Project

Bumblebee pollinators Pheromones can help to manage and protect bumblebee colonies. (LD15102)

The aim is to understand chemical signals that mediate communication and information transfer within bumblebee colonies as well as biosynthetic pathways leading of the bumblebee wax moth, Aphomia sociella, a parasite able to destroy...

Project

Insect pollinators Chemical communication and regulation mechanism in bumblebees. (OC 828.20)

Chemical nature of signals playing important role in the development of a bumblebee colony will be studied. The queen's pheromone and dominant signals of workers regulate the behaviour of the colony members and thus, they influence the colon...

Bumblebeekeeping The influence of chemical signals on activation of queens under laboratory conditions. (EP9160)

The important problem of bumblebee keeping under laroratory conditions is building of the first brood cell by the queen - oviposition. For the activation of bumblebees or honeybees, presence of brood, two queens in nest. No way fulf...
