Bruchus rufimanus
Broadbean Weevil, Broad Bean Beetle, Broad Bean Seed Beetle
Bruchus rufimanus is a univoltine leaf beetle and major agricultural pest of faba beans (Vicia faba). Adults feed on pollen and nectar, particularly from Fabaceae, while larvae develop inside seeds where they are protected from control measures. The species exhibits precise phenological synchrony with its host plant, with adult colonization timed to crop flowering. Sexual maturation is triggered by photoperiod and pollen consumption, with females becoming reproductive after ingesting faba bean pollen. Overwintering occurs as dormant adults in protected sites or as larvae/pupae within stored seeds.
