The warm weekend has increased pest activity

Not surprisingly, the warm weekend has moved things on a bit at Wellesbourne. Today our 3 water traps contained a total of 16 female and 130 male cabbage root flies. We also found some cabbage root fly eggs around plants in our monitoring plot (11 eggs from 15 plants). In addition, we caught our first silver Y moths in pheromone traps.

Still no carrot fly on our traps. We definitely have overwintering pupae in the vicinity so are expecting to catch some carrot flies soon.
