Abstract
The Malaysian fruit fly, Dacus taufrons (Hendel), is the most recent fruit-infesting tephritid to become established in Hawaii. This species was reared in our laboratory on pepper, Capsicum annum L., a commonly infested host in Hawaii. At a constant temperature of 26.6°C duration of preadult development was 21 days. Mortalities of 19, 30, and 16% were recorded for the egg, larval, and pupal stages, respectively. Mean total eggs per female oviposited in pepper was 256.2 and mean female longevity 64.1 days. With a mean generation time of 48.1 days and a net reproductive rate of 61.1, intrinsic rate of increase was 0.09, a value lower than that of other Dacus species in Hawaii.
