This project aims to discover molecules that are toxic to one of two major honeybee pests - Varroa mites and the small hive beetle (SHB) - but at the same time are safe for honeybees themselves. Such molecules will be starting points for the development of safer, more selective insecticides that support the pollination industry.
These molecules will be designed to interfere with the activity of a protein (known as EcR) that is essential for the survival all insects and mites, but the project team predict is subtly different in shape in honeybees, Varroa and SHB. These differences should allow molecules with specific shapes to selectively interfere with the protein in the pests but not the honeybee.
To execute this project, the project team need to make purified samples of the EcR protein from each of the three species above. The first step in this process is to obtain the DNA sequences from the three species that encode the EcR protein in each case. These sequences then need to be genetically engineered to ultimately allow the project team to produce the protein from each species.
Over the last six months, the project team have successfully identified the EcR sequence from honeybee, Varroa and SHB and have carried out genetic manipulations that will enable the production of the three versions of the EcR protein.
