Pest update from Wellesbourne

When the water traps in the 2019 swede plot were checked today there were:

  • 2 male and 3 female cabbage root flies
  • 70 bean seed flies
  • 1 flea beetle
  • 136 pollen beetles
  • 2 cabbage stem weevils
  • 0 cabbage stem flea beetles
  • 0 cabbage seed weevils

There were 4 carrot flies on the 3 sticky traps in the new plot for 2019.

No cabbage root fly eggs were laid between 10 and 14 June (around 15 plants).

15 diamond-back moths were captured. No moths were captured in our other pheromone traps (turnip moth, silver Y moth, cabbage moth, diamond-back moth). There are 2 traps for each species.

We also caught 28 diamond-back moths on the carrot fly traps. There was a large influx of moths into the UK on 12th June.
