Between Friday and today we caught:

On 3 sticky traps in each of our carrot plots:

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

• 15 male cabbage root flies and 9 females
• 41 bean seed flies
• 1088 pollen beetles
• 99 flea beetles
• 8 cabbage stem weevils
• 6 cabbage seed weevils

We also recovered 9 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 and caught 1 diamond-back moth and 1 turnip moth (2 traps per species).

We have also caged some areas planted with narcissus in order to record emergence of large narcissus fly - two caughts today!
