Abstract
Abstract The biology and development of Lixadmontia franki Wood and Cave (Diptera: Tachinidae), an endoparasitoid of bromeliad-eating weevils in the genus Metamasius, are described. Embryonic development is completed within 8 d post-mating while the egg is held inside the female reproductive system. Neonate larvae actively search for a host and initiate parasitism by penetrating the host’s cuticle. Larval developmental time and pupation at 20°C averaged 17 and 25 d, respectively, with no significant differences observed between genders. Adult males live on average 9 d compared to 17 d for females. Females are capable of parasitizing third to sixth instars of Metamasius quadrilineatus Chevrolat, but the highest levels of parasitism were observed when third and fourth instars were exposed to flies.
