Xie, Y.P., & Zheng, L.Y. 2002 [Ultra-morphology and infrared absorption spectra of the waxes secreted by a scale insect, Didesmococcus koreanus (Homoptera: Coccidae).]. Acta Entomologica Sinica 45(3): 329-335.

Notes: The ultra-morphology and chemical composition of the waxes secreted by the scale insect, Didesmococcus koreanus Borchs., was studied with scanning electron microscope and infrared spectra techniques. It was thought that the waxes secreted by the young nymphs are long threads in its shape. In fact, the waxes changed shape on the dorsal surface of the old nymphs and adult females.
