Abstract

Pine stands of the [Adriatic] coast and Blastophagus [Myelophilus] piniperda: a bad combination.

Abstract

An account of the dangerous infestation of B. piniperda in the Pine stands on the northern Adriatic coasts since the cold winters of 1962/63 and 1963/64. The stands are mainly of Pinus pinea, here at or beyond the limits of its natural range and easily attacked by other insects e.g. Aradus cinnamomeus and Dioryctria sylvestrella. In this environment B. piniperda, whose cycle takes place in turn on weakened stems and thriving shoots, continuously shifts the physiological balance of the trees in its favour, maintaining its populations at an exceptionally high level. Possibilities of control (at present mainly silvicultural) are discussed in relation to the long breeding season of the beetle.
