The cultivation of faba beans is only of minor importance in Germany in the arable sector. In 2018, less than 0.5% of Germany's arable land was cultivated with faba beans (DESTATIS, 2019, o. S.). This fact is astonishing, as faba beans have a wide variety of uses. They can be used as domestic, GMO-free protein feed in animal nutrition and in human nutrition. Further positive ecosystem services are also available.

The policies of the Federal Government of German and the German Federal States support the cultivation of domestic grain legumes through various measures. With increasing intensification of faba bean cultivation, the pressure of infestation with various fungal diseases and pathogens is also increasing.

One type of these pests are seed beetles of the species Bruchus rufimanus Boheman. This pest called faba bean weevil, causes quality and yield losses in faba bean cultivation. The impairment of quality is mainly caused by drill holes in the beans, which are associated with a visual change and increased susceptibility to diseases. In addition, the presence of beetle pupae or beetles in the beans also leads to restrictions in their use for human nutrition or seed production. In addition to the principles of integrated crop protection, control measures against these pests using insecticides are also imaginable.

In this research and comprehensive reportĀ  the author (Ina Stute) explores the crop, the issues affecting the crop and the effects of insecticide treatments on crop damage by the faba bean beetle.
