Development of microsatellite markers and estimation of inbreeding frequency in the parasitoid wasp Melittobia
The parasitoid wasp Melittobia is an important insect for basic and applied biology. Specifically, their extremely female-biased sex ratios, which contrast to the prediction of pre-existing theories, are needed to be explained from the aspect of evolutionary biology. In this study, using next-generation sequencing, 20 microsatellite loci were developed and characterized for M. australica. The d...
متن کاملPlant secretions prevent wasp parasitism in nests of wool-carder bees, with implications for the diversification of nesting materials in Megachilidae

The highly diverse Megachilidae us...
متن کاملOffspring production and development in the parasitoid wasp Melittobia clavicornis (Cameron) (Hymenoptera: Eulophidae) from Japan
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 approximat...
متن کاملCompetition between relatives and the evolution of dispersal in a parasitoid wasp.
Evolutionary theory predicts that levels of dispersal vary in response to the extent of local competition for resources and the relatedness between potential competitors. Here, we test these predictions by making use of a female dispersal dimorphism in the parasitoid wasp Melittobia australica. We show that there are two distinct female morphs, which differ in morphology, pattern of egg product...
متن کاملVirginity and the clutch size behavior of a parasitoid wasp where mothers mate their sons.
Theoretical and empirical research on the evolution of clutch size has proved to be an extremely productive area of evolutionary biology. A general prediction is that individuals should produce a smaller number of offspring when resources are more limited, such as when multiple individuals compete for the same resources for their development. However, we expect that the opposite prediction aris...
