Notes: Abstract: Many diaspidids occur on tea, but rarely become serious pests, probably because pesticides use has been minimal and natural enemies have been conserved; different species of scales prefer different feeding sites on the plant; economic importance, biology, natural enemies, and chemical control are discussed; tables list diaspidids collected from tea with country in which they occur. Keywords: biological control.
