Xylella is transmitted by insects to host plants. BRIGIT will investigate this relationship, the species involved and the wider movement of insects across countries.Link to insect vector systematics, distribution and genomics databases and further information
BRIGIT will build on established citizen science and outreach activities to improve awareness of Xylella, its potential impacts and modes of spread.
We will work with established volunteer networks and recording schemes as well as engage with citizens in the wider community.
Become a reporter
To be able to respond to the threat of Xylella we need to link the public, and researchers and enthusiasts from different disciplines to record insect and plant distributions across the country. There are established volunteer networks reporting such information and BRIGIT aims to work with these groups. More information of how to join these volunteer networks will be added soon.
During the project tools to enable non-specialists to identify morphologically potential vectors of Xylella will be developed. The following resources are currently available
- Look for leafhopper vectors of Xylella
- Look for froghopper vectors of Xylella (in construction)
- Look for xylem-feeding insect vectors of other plant pathogens
In the meantime, we encourage people to report the presence of any of the approximately 20 leafhopper and froghopper species that are suspected to be Xylella vectors (see table below) and to identify the associated plant host species using the existing LEDRA website.

A suite of educational/outreach material will be developed which will be freely available and downloadable to provide information on identification of the most common host plants and symptoms of the disease.
Public events and training will be created through BRIGIT to bring together volunteers and share information on Xylella. These events will be announced on the BRIGIT website and associated media channels.
