Pest update from Wellesbourne

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

• 2 male and 3 female cabbage root flies
• 9 bean seed flies
• 14 flea beetles
• Approx 10,500 pollen beetles
• 19 cabbage stem weevils
• 4 cabbage stem flea beetles
• 0 cabbage seed weevils
  

There were 11 carrot flies on the 3 sticky traps in the new plot for 2019.

121 cabbage root fly eggs were laid between 21 and 25 June (around 15 plants).

4 diamond-back moths and 1 turnip moth were captured. No moths were captured in our other pheromone traps (silver Y moth, cabbage moth, diamond-back moth). There are 2 traps for each species.

We also caught 4 diamond-back moths on 5 carrot fly traps, 3 of which are in our carrots (above) and 2 are in the swede plot and are baited with a pheromone lure (experimental).
