Abstract
Satin moth, Leucoma salicis (L), larvae from parents which fed on eastern cottonwood and largetooth aspen were laboratory-reared from eclosion to diapause (3rd stage) on fresh foliage of seven poplar and one willow species. Larvae from parents which fed on eastern cottonwood weighed more at eclosion, developed more rapidly, had higher survival, and gained more weight by the onset of diapause relative to larvae from aspen-fed parents. Larvae which were fed the host foliage of their parents developed more rapidly. The highest survival and greatest weight gains occurred where progeny of individuals that developed on eastern cottonwood were reared on that host. Lombardy poplar and eastern cottonwood were the most suitable host species, while white, Simon, and balsam poplars were the least suitable.
