Pest update from Wellesbourne
Between Friday and today we caught:
On 3 sticky traps in each of our carrot plots:
- 24 carrot flies - overwintered carrots
- 177 carrot flies - spring-sown carrots
In 4 water traps - 3 near our overwintered swede plot and 1 near some oil seed rape:
- 84 male cabbage root flies and 11 females
- 60 bean seed flies
- 561 pollen beetles
- 11 flea beetles
- 4 cabbage seed weevils
We also recovered 36 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 silver Y moth (2 traps).
We have also caged some areas planted with narcissus in order to record emergence of large narcissus fly - none so far.
