Abstract

We provide a dichotomous key, with photographs and illustrations, for distinguishing between instars of the pea aphid (Acyrthosiphon pisum) in the developmental pathway leading to the apterous parthenogenetic adult. Lengths of body, antenna and cauda are provided for a sample of each instar.
