Brassica pests at Wellesbourne
Pest pressure on the brasica crops at Wellesbourne is currently very high. We have captured very large numbers of aphids in the suction trap - both Myzus persicae and Brevicoryne brassicae - and they can be found on plants. Some of these have been parastised. The plants are also quite heavily infested with diamond-back moth larvae and one pupa was found yesterday. Other pests include flea beetles and small numbers of cabbage whitefly. One of the diamond-back moth larvae is shown below.
