The strawberry plants damage, caused by Coroebus alatus F., is established in 1989, in some localities of Serbia (Yugoslavia). This species has one generation in the year, and is overwintering as larvae in the lowest part of the strawberry root. In the spring, the larvae change into pupae in their pupal cradle which is at the level of the initial opening, where larvae bore from the eggs which are laid usually in the axil of older leaves. The emergence period of imagos is very prolonged. In the spring adults are feeding on the strawberry leaves, but such damage is not serious. The larvae, however, are very harmful, attacked plants making spiral galleries through the root. Only one larva of C. elatus lives in each root. Such plants have yellow and wither leaves, and later the whole plants died. The control of C. elatus is possible by mechanical measure, which consists in removing and destroying of infested strawberry plants. Chemical control is also suggested during the period of imagos activity.
