Unpublished field observations in Leucauge argyra, a tropical orb weaver spider, suggest the occurrence of conspicuous mating plugs that could reduce or prevent remating attempts. Otherwise, the sexual behavior of this ...

After mating, females may experience a decline in sexual receptivity and attractiveness that may be associated with changes in the production and emission of sex pheromones. In some cases, these changes are produced by ...

Este trabalho descreve os primeiros três casos em que grilos machos monopolizam suas fêmeas através de plugues de acasalamento. A origem dessas estruturas varia entre os casos (i.e., não há homologia entre as mesmas). A ...

We describe two new aspects of male reproduction in the pit viper Bothrops cotiara: the formation of mating plugs and epididymal sperm storage. Based on histological analyses of specimens (four males and three females), ...

Mating plugs have been proposed as a mechanism that has evolved to avoid sperm competition. Their structure and composition vary across taxa and are related to the effectiveness of its function. This effectiveness could ...

"Geographic distribution and its interconnected biotic and abiotic factors, may favor variation in the expression of sexual displays. In Leucauge orb web spiders females participate in mating plugs formation and use them ...
