Despite the diverse array of mating systems and life histories which characterise the
parasitic Hymenoptera, sexual selection and sexual conflict in this taxon have been …

Multiple mating by females is widely thought to encourage post-mating sexual selection and
enhance female fitness. We show that whether polyandrous mating has these effects …

Insects display a staggering diversity of mating and social behaviours. Studying these
systems provides insights into a wide range of evolutionary and behavioural questions, such …

Gene expression divergence between closely related species could be attributed to both cis-
and trans-DNA sequence changes during evolution, but it is unclear how the evolutionary …

The good-sperm and sexy-sperm (GS-SS) hypotheses predict that female multiple mating
(polyandry) can fuel sexual selection for heritable male traits that promote success in sperm …

Methods: Three experiments: two assessed the effect of size on mating success, one with
and one without the presence of a competitor; the third experiment explored the relationship …

The taxonomically widespread nature of polyandry remains a puzzle. Much of the empirical
work regarding the costs and benefits of multiple mating to females has, for obvious reasons …

The parasitoid wasp genus N asonia has rapidly become a genetic model system for
developmental and evolutionary biology. The release of its genome sequence led to the …

Highlights•Mass-releases of males exert selective pressure on wild mosquito
populations.•Evolution of mating behaviors could affect the control efficacy and …

In hymenopterans, males are normally haploid (1n) and females diploid (2n), but individuals
with divergent ploidy levels are frequently found. In species with 'complementary sex …
