Pest update from Wellesbourne

Between Tuesday (13th) and Friday (16th) we found:

• a whopping 1174 carrot flies on traps in this year's carrots (3 traps) (see yesterday's blog)
• 10 winged and 2 wingless willow-carrot aphids on 3 x 0.5 m lengths of carrot row

In the 3 water traps in the 'new' cauliflower plot:

• 24 male and 36 female cabbage root flies
• 110 bean seed flies
• 26 pollen beetles
• 25 flea beetles - these have increased in number since the last sample was taken
• 9 cabbage stem weevils - also an increase in numbers

We collected a total of 184 cabbage root fly eggs from around 15 cauliflower plants (planted 15 April).

There were no diamond-back or silver Y moths

We have pheromone traps out for European tarnished plant bug and common green capsid - and caught 1 European tarnished plant bug.
