In seeds of the various kinds of pea and bean plants different granivorous weevils live.
They infest the seeds already when the plants are in the fields and are later on transported to warehouses where they can continue to do damage. The result is seen as rotten peas, beans, lentils etc. Most of these weevils belong to the family Bruchidae and the species which are particularly harmful are found in the genera Bruchus, Acantoscelides and Callosobruchus. The most common of these weevils in Europe is the bean weevil.
