Bramble Berry Pests
Aphids, also known as greenfly/blackfly or plant lice, are minute plant-feeding insects. Aphids are distributed world-wide, but they are most common in temperate zones. It is possible for aphids to migrate great distances depending on the weather patterns (mainly passive dispersal riding on winds). Look for aphids in late spring and early summer, especially on the underside of the leaves near the tips of the canes. If more than two aphids per cane are found, treat with a pesticide. Aphids overwinter on brambles, so when you prune, be sure to destroy the clippings.
