Pest update from Wellesbourne

Between Friday and today we found the following:

On 3 sticky traps:

  • 13 carrot flies

In 3 water traps in a plot of swedes.

  • 0 male cabbage root fly and 1 female
  • 1 bean seed fly
  • 5 pollen beetles
  • 1 cabbage stem flea beetle

We have stopped sampling for cabbage root fly eggs.

We caught 4 silver Y moths in our pheromone traps. It is unlikely that silver Y moths caught at this time of year will cause any damage to crops. More information on what they do in winter can be found here: http://www.pnas.org/content/109/37/14924.full.pdf
