Pest update from Wellesbourne
Between Friday (1st) and Monday (4th) we captured:
- 40 carrot flies on traps in this year's crop of carrots (3 traps).
- Carrot fly numbers still have not increased as 'expected' and it may be that the recent hot weather has caused at least some of the population to aestivate in the pupal stage. A similar thing happened at this time last year and although we captured low numbers of flies over an extended period, damage was high when we harvested our trials in the early autumn.
We collected a total of 15 cabbage root fly eggs from around our 15 newly-planted cauliflower plants.
The 3 yellow water traps caught:
7 male and 7 female cabbage root flies
- 12 bean seed flies
- 1 pollen beetle
- 107 flea beetles
- 4 small white butterflies.
There were no silver Y moths, no diamond-back moths and no turnip moths (2 pheromone traps per species).
