Studies of Predators of the Balsam Woolly Aphid, Adelges piceae (Ratz.) (Homoptera: Adelgidae): V. Laricobius erichsonii Rosen. (Coleoptera: Derodontidae), an Introduced Predator in Eastern Canada1,2

Published online by Cambridge University Press:  31 May 2012

Extract

Laricobius erichsonii Rosen. is one of several species that have been introduced into the Atlantic Provinces since 1933 for the biological control of the balsam woolly aphid, Adelges piceae (Ratz.). This small beetle occurs commonly on A. piceae infestations in Europe where it is one of the more numerous predators of the adelgid (Mesnil, 1950:). Franz (1953) described its range in Europe as from the Italian Alps to near southern Denmark and from Normandy almost to the Carpathian Mountains, srating that its distribution is bound to that of the Coniferae on which its prey live. Franz also described the morphology of all stages in detail and discussed the bionomics and ecology in Europe. Prior to these studies the biology of thc insect was unknown.
