Pest update from Wellesbourne

Between Friday and today we caught:

On 3 sticky traps in each of our carrot plots:

• 78 carrot flies - overwintered carrots
• 206 carrot flies - spring-sown carrots

In 4 water traps - 3 near our overwintered swede plot and 1 near some oil seed rape:

• 5 male cabbage root flies and 2 females
• 23 bean seed flies
• 215 pollen beetles
• 27 flea beetles
• 16 cabbage stem weevils
• 3 cabbage seed weevils
• 4 cabbage stem flea beetle

We also recovered 45 cabbage root fly eggs from the soil around 15 cauliflower plants.

We set up pheromone traps for silver Y moth, diamond-back moth and turnip moth on 18th April but none caught so far.

We have also caged some areas planted with narcissus in order to record emergence of large narcissus fly - none so far.
