Miyanoshita, A., & Tatsuki, S. 1995 [Host-associated differences in Aspidiotus cryptomeriae Kuwana (Homoptera: Coccoidea: Diaspididae). II. Morphology of Torreya nucifera race reared on non-host plant, Cryptomeria japonica D. Don.]. Japanese Journal of Applied Entomology and Zoology 39: 159-162.

Notes: Previous work showed that Cryptomeria japonica feeders and Torreya nucifera, feeders of Aspidiotus cryptomeriae are separate host races due to distinct morphological characters and virtually monophagous feeding habits; in this experiment, two populations of A. cryptomeriae were reared under the same conditions except for the host plant; there were no significant differences between them for five morphological characters except for pygidium length; results generally indicate that the T. nucifera feeding race has very stable morphology that is not affected by the host plant.
