• Biological 'lure and kill' system for bean weevils shows promise

    Biological ‘lure and kill’ system for bean weevils shows promise

    A biological control system for beetle pests of peas and beans would reduce the need for blanket insecticide application and help to reduce the issues with resistance.

    Trials by PGRO at the Beeswax Farming Stubton Estate, near Newark include a ‘lure and kill’ trial.  This is investigating the use of a naturally occurring fungus to control pea and bean weevil and, potentially, bruchid beetle. Currently, the main insecticides available to UK pulse growers for control of both pests are pyrethroids – and there is now evidence of partial resistance developing in pea and bean weevil populations.
