We also recovered 6 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 5 turnip moths (2 traps per species).
We have also caged some areas planted with narcissus in order to record emergence of large narcissus fly - two more caught today!
