Abstract
A description is given on mites and small insects, which damage health and cause discomfort in indoor environment. For indoor-environmental studies, mites and small insects are classified into the following three types: “indoor space outbreak type” coming from infested construction materials and ventilation ducts,“outdoor outbreak invasion type” brought indoor from affected plants in the garden and verandah, and “article adhesion invasion type” carried in with furniture and goods from outside. Another classification, by ecology and the pattern of damage to humans, divides them into sanitary insect pest, house-hold insect pest, food stuff insect pest, clothing harmful insect pest, and nuisance, among others.
This paper discusses the morphological and ecological characteristics of 12 kinds of mites [American house dust mite (Dermatophagoides farinae) et al.] and 19 kinds of insects [cigarette beetle (Lasioderma serricorne) et al.] that typically infest indoor environment.
