Evolution of insect wing traits might be promoted or constrained by differential flight demands across sexes, which are currently less explored in social hymenopterans, despite striking differences in flight behavior of males and females. We aim to test for sex specificity in wing morphometry in some Polistes wasps, a model genus in morphological and behavioral studies. We expect males to…
Sexual selection is the evolutionary mechanism by which certain characteristics are favored (sexually selected) when an individual's reproductive chances is increased. It has been extensively studied in a variety of organisms. Still, some groups have received relatively little attention. This is the case of social Hymenoptera (bees, ants and wasps). Mating systems such as leks and swarms …
To maximize fitness, males of social hymenopterans (ants, bees, and wasps) invest in direct reproduction rather than helping their kins. However, direct reproduction is constrained by sexual maturation. It takes a few days of adult life for sperm to migrate from the testes to the storage organs (seminal vesicles). It is only from the seminal vesicles that sperm can be mixed with accessory…
Sexual selection is a major evolutionary force that has been extensively studied in many animals, but social insects are still a notable exception. This is surprising because some peculiar aspects of their reproductive biology allow general principles of sexual selection to be tested in unusual contexts. For example, in male social wasps, spermatogenesis is restricted to the immature stag…
Male ants, bees and social wasps (Hymenoptera) are relatively short-lived, but their ejaculates can survive for a long time in the female reproductive tract. The low investment in somatic maintenance suggests that these insects prioritize reproduction over survival. It is possible that an increase in the probability of death results in greater reproductive effort, as proposed by the "term…
Sperm selection in the female reproductive tract is common in many animals and may allow only the "best" gametes to fertilize. In this sense, spermatozoa may have an "optimal phenotype". Despite intra-individual morphological variation in male gametes, few studies have demonstrated that, in the same male, morphologically distinct subpopulations of sperm are more likely to reach the site o…
During the mating season, males and future queens of social insects left colonies to find a sexual partner. In this period, individuals typically interact with different potential partners before choose that one/those ones to copulate with. The main objective of this project is to investigate, in social wasps, the adaptive meaning and the proximal mechanisms involved in mate choice. As st…
Female preference for specific sexual partners can evolve even in species where the male reproductive contribution is minimal (only the ejaculate). Although indirect benefits such as "good genes", "sexy sons" and genetic compatibility are tipically invoked to explain such a phenomenon, a simple alternative is that male reproductive quality (for example, ejaculate quality), is associated w…
