A Strain of the predatory mite C. malaccensis was isolated from a colony of the grain mite Aleuroglyphus ovatus, and has been furtherly cultured on it as a host in the laboratory. Arrhenotokous parthenogenesis is assessed in the species. The females were found to pass the five stages, egg, larva, protonymph, deutonymph and adults; while in males the deutonymphal stage was absent. Under the same conditions of 25° +/- 0.1° and 75 +/- 2 % R. H., the females total !ife from egg to adult took a longer period (20-23 days) than males (15- 17 days).
