Expulsion and consumption of male ejaculates by promiscous female euxesta eluta and euxesta mazorca (Diptera: Ulidiidae)
(Taylor & Francis Ltd, 2018-06)
While expulsion of male ejaculates by the females after copulation has been reported for various animal groups, expulsion followed by consumption of the expelled ejaculate is a rare behaviour outside spermatophylax-producing ...
Reproductive interference between two sibling species of gift-giving spiders
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTDLONDON, 2012)
We investigated the possibility of reproductive interference between two sibling spider species, Paratrechalea azul and Paratrechalea ornata, which occur syntopically and reproduce synchronously. Males of both species offer ...
Female preferences based on male nutritional chemical traits
(Springer, 2010-05-01)
Selection favors females that attend to reliable information about male genetic quality and fitness. Male nutritional condition can be a significant sign of mate quality since poor nutrition can be related to reduced sperm ...

Sexual behaviour of the Mediterranean fruit fly (Diptera: Tephri- tidae): the influence of female size on mate choice
(2011)
Most studies of the sexual behaviour of the Mediterranean fruit fly Cera-titis capitata Wiedemann 1824 (Tephritidae: Ceratitidini) have concen-trated on determining which male characteristics influence their
copulatory ...
Lack of mate selectivity for genetic compatibility within the red brocket deer Mazama americana complex
(2017-01-01)
Red brocket deer Mazama americana includes at least two lineages that differ at the level of karyotypes and phylogenetic relationships based on mtDNA. Also, hybrids between them have been proved to be nonviable or infertile. ...
Infestation of fruit by conspecific and heterospecific females deters oviposition in two Tephritidae fruit fly species
(Wiley, 2020-09)
Tephritidae fruit fly larvae develop entirely in the host chosen by the females. To improve the fitness of their progeny, females would benefit from rejecting previously exploited hosts. Anastrepha fraterculus and Ceratitis ...
Burrow ornamentation in the fiddler crab (Uca leptodactyla): female mate choice and male–male competition
(2016-09-02)
Non-biological ornamentation is found in the nests and burrows of different kinds of animals. We evaluated here whether sand hoods constructed by male fiddler crabs (Uca leptodactyla) are one of the signals used by males ...
Experimental modifications imply a stimulatory function for male tsetse fly genitalia, supporting cryptic female choice theory
(THE AUTHORS. J. EVOL. BIOL. 22 (2009) 151 6-1525 JOURNAL COMPILATION, 2009)
One of the most sweeping of all patterns in morphological evolution is that animal genitalia tend to diverge more rapidly than do other structures. Abundant indirect evidence supports the cryptic female choice (CFC) ...
