Abstract

In the UK, larvae of Byturus tomentosus (Deg.) are a serious pest of raspberries, loganberries, tayberries and blackberries. In plantations where no control measures are taken, the beetle can multiply rapidly and crops can be so badly attacked as to become valueless. Infested fruit is unsuitable for processing or for the fresh fruit market, where the presence of larvae renders consignments unattractive to buyers. This amended leaflet contains information on the morphology, life-history, injuriousness and chemical control of the beetle.
