Abstract

The development time, sex ratio and offspring production of Melittobia clavicornis reared with wild, facultative and factitious hosts are presented. Known hosts and different biological aspects presented in previously published reports are summarized and clarified. Immature development time was equivalent or slightly longer than that of other Melittobia species, and the sex ratio was approximately 97% female. Total offspring numbers were considerably lower than that of other Melittobia species using the same hosts. We report female dimorphism in this species for the first time. The number and relative proportion of brachypterous morph females produced was higher than that in other species of the genus.
