Bean seed fly monitoring 2021
This year we will be monitoring bean seed fly in a number of locations and will summarise our counts here. Traps are run by PGRO and the University of Warwick.
The graph below shows the trap captures of adult flies at Warwick Crop Centre, Wellesbourne from early November 2020. It shows the numbers of flies captured per trap per week.
The table below summarises the counts on which the graph is based.
