Beet Moth
Beet Moth Monitoring
BBRO's network of smart moth traps is now in operation and records numbers of moths.
The MothWatch map displays the total numbers of moths caught during a week at each of our pheromone traps. Simply choose the week you wish to see from the dropdown-menu in the top right.
We expect to see signs of damage from the larvae of beet moth between 2 and 4 weeks after each migration. Thoroughly inspect your crops for signs of damage and be prepared to treat where necessary.
Note: Sites where a trap is not functioning correctly are coloured grey.

Virus Yellows Forecast 2026
Rothamsted Research are forecasting the 2026 VY Risk at 62% (East - Bury St Edmunds, Cantley, Wissington) and 49% (North - Newark).
This risk is higher than 2025 but lower than 2024.
Early prediction of migration dates (as of 1st March) suggest migration as end of April (Eastern areas) or beginning of May (North). These may change due to the impact of weather conditions. Please see the latest Advisory Bulletin for updates.
