Copulatory courtship by internal genitalia in bushcrickets
Male genital organs are among the fastest evolving morphological structures. However, large parts of the male's genitalia are often hidden inside the female during mating. In several bushcricket species, males bear a pair of sclerotized genital appendices called titillators. By employing synchrotron-based in vivo X-ray cineradiography on mating couples, we were able to visualize titillator move...
متن کاملNo apparent indirect genetic benefits to female red flour beetles preferring males with intense copulatory courtship.
Whether females gain indirect genetic benefits through mate choice is a controversial issue since this requires additive genetic variance in the preferred male traits. Condition dependence could maintain the necessary genetic variance by linking the expression of male traits to the supposedly large number of genes affecting condition. Copulating males of the red flour beetle Tribolium castaneum...
متن کاملFemale cooperation in plug formation in a spider: effects of male copulatory courtship
One of the strongest indications that cryptic female choice is an evolutionary phenomenon of general importance is the widespread existence of male courtship behavior during copulation. It has been presumed that such copulatory courtship functions to induce female reproductive behavior that favors the male’s reproductive interests, but this function has seldom been demonstrated. Here, we examin...
متن کاملCryptic female choice via sperm dumping favours male copulatory courtship in a spider.
Males of many animals perform 'copulatory courtship' during copulation, but the possible reproductive significance of this behaviour has seldom been investigated. In some animals, including the spider Physocyclus globosus (Pholcidae), the female discards sperm during or immediately following some copulations. In this study, we determined which of several variables associated with copulation cor...
متن کاملCopulatory courtship song in Lutzomyia migonei (Diptera: psychodidae).
Lutzomyia migonei is a vector of leishmaniasis with a wide distribution in South America, which could favour population differentiation and speciation. Cryptic species of the Lutzomyia longipalpis complex, the widely distributed sand fly vector of visceral leishmaniasis in Latin America, have previously been shown to display distinct copulation songs. We found that Lu. migonei males also produc...
