Management of the broad bean weevil (Bruchus rufimanus Boh.) in faba bean (Vicia faba L.)

Roubinet, Eve
SummaryBruchus rufimanus Boh. is a common pest on faba beans (Vicia faba L.) all over Europe and worldwide. The area of faba bean production is increasing in Sweden and in Europe, partly encouraged by the CAP subsidies for legume crops and diversified crop rotations. At the same time, number of the insecticides commonly used against B. rufimanus have been removed from the market as pollinators risk to be harmed as the treatment timing corresponds to crop flowering. In Sweden, only one insecticide is available and its efficacy against B. rufimanus is not well established. The pest pressure is likely to increase if no measures are taken to reduce the population. This has increased the interest in alternative management methods in Europe, particularly so in the UK and in France where faba beans is extensively grown. This report presents an overview of B. rufimanus biology and management strategies. This report is the result of a literature search including scientific literature and other available documentations (e.g., grower organizations, technical institutes). Additionally, contacts with technicians, referring advisors and researchers across Europe involved in research projects related to B. rufimanus management, enabled me to obtain an up-to-date overview of the advancement of their projects that I present in this report. In conclusion I suggest further investigations that would clarify the risks for faba bean production and help identify measures both in term of field management and direct control that could be recommended in Sweden.
