Twin intromittent organs of Drosophila for traumatic insemination.
In several animals, male genitalia create insemination wounds in areas outside the genital orifice of females. I report that such traumatic insemination (TI) occurs in the Drosophila bipectinata complex (Diptera: Drosophilidae) and illustrate a previously unknown evolutionary pathway for this behaviour. Flash fixation of mating pairs revealed the dual function of the paired claw-like basal proc...
متن کاملTraumatic insemination and sexual conflict in the bed bug Cimex lectularius.
The bed bug, Cimex lectularius, has a unique mode of copulation termed "traumatic" insemination [Carayon, J. (1966) in Monograph of the Cimicidae, ed. Usinger, R. (Entomol. Soc. Am., Philadelphia), pp. 81-167] during which the male pierces the female's abdominal wall with his external genitalia and inseminates into her body cavity [Carayon, J. (1966) in Monograph of the Cimicidae, ed. Usinger, ...
متن کاملCostly traumatic insemination and a female counter-adaptation in bed bugs.
Male bed bugs pierce females through the body wall and inseminate directly into the body cavity. It has previously been shown that such traumatic insemination carries costs for females, and sexual conflict regarding the mode of insemination should thus propel male-female coevolution. Since males accumulate sexually antagonistic adaptations, females should evolve counter-adaptations that efficie...
متن کاملThe spider Harpactea sadistica: co-evolution of traumatic insemination and complex female genital morphology in spiders.
The males of invertebrates from a few phyla, including arthropods, have been reported to practise traumatic insemination (TI; i.e. injecting sperm by using the copulatory organ to penetrate the female's body wall). As all previously reported arthropod examples have been insects, there is considerable interest in whether TI might have evolved independently in other arthropods. The research repor...
متن کاملPersonality disorder and self-wounding.
At least 1 in 600 adults wound themselves sufficiently to need hospital treatment. More men than women do it, although more women receive psychological treatment. Many have a history of sexual or physical abuse. Self-wounding differs from other self-harm in being aimed neither at mutilation nor at death. Self-wounding coerces others and relieves personal distress. Repeated self-wounding is one ...
