Beetle banks: do they really make a difference?

An evaluation of the usefulness of beetle banks in the control of aphids in cereal crops.

Year of Publication2009

Numbers of general insect predators increased in a beetle bank over the four years from its establishment, although they then declined sharply. Aphid numbers in the neighbouring wheat crop were greater in areas where the predators were excluded suggesting that beetles and spiders from the bank were delaying the establishment of the pest. This justification of the establishment of beetle banks should, however, be tempered by other considerations.
