Bruchus rufimanus (bean seed beetle) is an economically important pest of Vicia faba throughout Europe and became established as a serious pest in the UK in the early 1990’s. Female B. rufimanus oviposit onto developing pods, and hatching larvae bore through the base of the egg and the V. faba pod walls. Larvae feed and pupate in the seed and adult B. rufimanus emerge at crop senescence, leaving a round hole, approximately two to three millimetres in diameter in the V. faba grain. Damage to grain quality affects the end use, and major existing markets for V. faba grown in the UK include those for UK animal feed, seed and for export for human consumption. Grain traders exercise strict quality requirements for freedom from staining and pest damage and for exported grain intended for human consumption, damage caused by B. rufimanus must not exceed 2% in V. faba produced in the UK.
Management of B. rufimanus has proved difficult and the choice of insecticides approved in V. faba in the UK is currently limited. The principal objective of the research was to improve management of B. rufimanus in V. faba and in particular to:
