Abstract

Aspen (Populus tremuloides Mich.) is the primary host of the aphid Pachypappa tremulae (L.). As with many other aphid species, part of its life cycle takes place on an alternate host unrelated taxonomically to the primary host. Thus, P. tremulae lives part of its cycle on spruce roots. Although there has been infrequent mention of this insect on conifer roots in the natural environment, P. tremulae seems particularly well adapted to the conditions offered by the roots of seedlings growing in containers. This document seeks to gather together current knowledge of P. tremulae.
