Kato, H., Hata, T., & Tsukada, M. 2004 Potentialities of natural dyestuffs as antifeedants against varied carpet beetle, Anthrenus verbasci.. JARO, Japan Agricultural Research Quarterly 38(4): 241-251.

Notes: We studied damage to wool fabrics dyed with different natural and chemical dyestuffs by the larvae of varied carpet beetle, A. verbasci, as part of a study on the functions of natural dyestuffs. Eight of ten natural dyestuffs showed an antifeeding effect against A. verbasci. Strength of the antifeeding effect of natural dyestuffs in a feeding preference test was in the order lac dye, gallnut, catechu, red cabbage, Cricula cocoon extract > cochineal, indigo, Amur cork tree extract > chemical dye.
