Inter and intraspecific variation in female remating propensity in the cactophilic sibling species Drosophila buzzatii and D. koepferae
Post-mating sexual selection by means of sperm competition or cryptic female choice occurs in species in which females remate before exhausting sperm supplied by previous mates. Thus, sperm competition is expected to be ...
Female receptivity in Anastrepha ludens (Diptera: Tephritidae) is not modulated by male accessory gland products
In numerous insects, accessory gland products (AGPs) transferred from males to females during mating are responsible for female sexual inhibition, but these products can be affected by male condition. Here, we investigated ...

The male ejaculate as inhibitor of female remating in two tephritid flies
(Pergamon-Elsevier Science Ltd, 2016-05)
The inhibition of female receptivity after copulation is usually related to the quality of the first mating. Males are able to modulate female receptivity through various mechanisms. Among these is the transfer of the ...
Different sperm allocation strategies in two populations of the semiterrestrial crab Neohelice granulata (Brachyura, Grapsoidea, Varunidae)
(Wiley Blackwell Publishing, Inc, 2016-08)
Sperm reserves are costly to produce and so the development of different sperm allocation strategies may be advantageous. Knowledge of sperm allocation strategies is important from an evolutionary perspective because they ...
Pollination triggers female gametophyte development in immature Nicotiana tabacum flowers
(Frontiers Media Sa, 2015-07-22)
In Nicotiana tabacum, female gametophytes are not fully developed at anthesis, but flower buds pollinated 12 h before anthesis produce mature embryo sacs. We investigated several pollination-associated parameters in N. ...
Female Age Determines Remating Behavior in Wild Mexican Fruit Flies: Abraham et al.: Age Effects on Female Remating in A. ludens
(Springer/Plenum Publishers, 2016-05)
Male and female age are important factors that can influence mating and remating behavior. Females can discriminate against or prefer older males, but there have been relatively fewer studies on how female and male age ...

Hearing is one of the most important senses for establishing a satisfying communication among people. This way, individuals stroked by different kinds of hearing losses show difficulties on speech-reception and in their ...
Females of a gift-giving spider do not trade sex for food gifts: a consequence of male deception?
(Biomed Central, 2017-05)
Polyandry is commonly maintained by direct benefits in gift-giving species, so females may remate as an adaptive foraging strategy. However, the assumption of a direct benefit fades in mating systems where male gift-giving ...
