NON-DIAPAUSE IN LABORATORY-REARED NORTH AMERICAN ORGYIA SPP. AND AUSTRALIAN TEIA ANARTOIDES (LEPIDOPTERA: LYMANTRIIDAE)

spp., voltinism is generally poorly defined or indefinite(Ferguson, 1978) and has received little attention, even in Europe (Corley , 1984).Voltinism of a species is often implied only from records of adults (e.g. Fer guson,1978; Corley, 1984), which can easily be biased by sampling efforts, and is notoften demonstrated by actual rearing.
