The common red spider or two-spotted mite, Tetranychus telarius L., has only recently become a major pest of deciduous fruit trees. This has happened in many parts of the world and appears to be associated with the use of DDT as a cover spray. DDT not only failed to control red spider, but actually increased the incidence of the mites by destroying insects that preyed upon them, thus upsetting the hitherto almost perfect natural control of the mites.
