“…However, recently, we found that hungry females tend to stay on food, allowing males to court and copulate (Ando et al. 2020). Furthermore, starved females with a food source kept relatively high copulation rates even in a larger chamber where females were able to escape from the courting male more easily, suggesting that the synergistic effect of hunger state and food availability plays a more important role in natural conditions than in the laboratory.…”

“…Although the effect of starvation treatment on nonvirgin females has not been confirmed, we think this preparation is more realistic to model the natural condition (Ando et al. 2020). Because starvation treatment increases the female receptivity in our experimental setup with food source, the observed remating rate would be higher than the one observed without starvation treatment (not tested in this study).…”

A courtship behavior that makes monandrous females polyandrous

Females of many animal species mate several times with different males (polyandry), whereas females of some species mate with a single male (monandry) only once. Little is known about the mechanisms by which these different mating systems evolve. Females of Drosophila prolongata mate serially, unlike Drosophila melanogaster females that refuse to remate for several days after their first mating (remating suppression [RS]). Nevertheless, interestingly, nonvirgin D. prolongata females refuse to remate with males that are prohibited from performing their species-specific courtship behavior, leg vibration (LV), suggesting that LV overrides RS making it cryptic in D. prolongata. In this study, we examined how long this cryptic RS persists. Surprisingly, it was sustained for at least 2 weeks, showing that RS is substantially augmented in D. prolongata compared to that of D. melanogaster. The two most closely related species to D. prolongata, Drosophila rhopaloa and Drosophila carrolli, do not perform LV and showed augmented RS, supporting the idea that augmented RS could have evolved before LV was acquired. These results suggested that D. prolongata females are intrinsically monandrous, whereas the newly evolved courtship behavior makes them polyandrous. This is a rare case in which a proximate mechanism of polyandry evolution from monandry is demonstrated.

“…Intrinsic factors include sexual maturation ( Prevot, 2015 ; Zhang et al, 2021a ), reproductive state ( Lynch et al, 2005 ; Phillips-Farfán and Fernández-Guasti, 2009 ; Zhou et al, 2014 ), nutritional state ( Jones and Wade, 2002 ; Grosjean et al, 2011 ; Lebreton et al, 2015 ), circadian rhythms ( Sakai and Ishida, 2001 ; Miller and Takahashi, 2013 ), sleep ( Lesku et al, 2012 ; Chen et al, 2017 ), and age ( Forslund and Pärt, 1995 ; Prosser et al, 1997 ; Moore and Moore, 2001 ; Brenman-Suttner et al, 2020 ). Extrinsic factors reflect both social and non-social environments, including the availability and quality of prospective mates and rivals ( Jirotkul, 1999 ; Preston and Stockley, 2006 ; Bretman et al, 2011 ), the risk of predation ( Rick and Dill, 1993 ; Godin and Briggs, 1996 ; Jirotkul, 1999 ), ambient light ( Gamble et al, 2003 ), seasonal changes ( Borg et al, 2006 ; Milner et al, 2010 ), temperature ( Gayou, 1984 ; Schnebel and Grossfield, 1984 ; Wilson, 2005 ; Conrad et al, 2017 ), and food availability ( Marsteller and Lynch, 1987 ; Harshman et al, 1988 ; Billeter and Wolfner, 2018 ; Ando et al, 2020 ).…”

Mating is essential for the reproduction of animal species. As mating behaviors are high-risk and energy-consuming processes, it is critical for animals to make adaptive mating decisions. This includes not only finding a suitable mate, but also adapting mating behaviors to the animal’s needs and environmental conditions. Internal needs include physical states (e.g., hunger) and emotional states (e.g., fear), while external conditions include both social cues (e.g., the existence of predators or rivals) and non-social factors (e.g., food availability). With recent advances in behavioral neuroscience, we are now beginning to understand the neural basis of mating behaviors, particularly in genetic model organisms such as mice and flies. However, how internal and external factors are integrated by the nervous system to enable adaptive mating-related decision-making in a state- and context-dependent manner is less well understood. In this article, we review recent knowledge regarding the neural basis of flexible mating behaviors from studies of flies and mice. By contrasting the knowledge derived from these two evolutionarily distant model organisms, we discuss potential conserved and divergent neural mechanisms involved in the control of flexible mating behaviors in invertebrate and vertebrate brains.

“…Food odours act as aphrodisiacs and promote courtship in Drosophila (Grosjean et al 2011, Gorter et al 2016, Ando et al 2020. Vinegar has traditionally been used as a source of food odorants in fruit fly research, and has a prominent synergistic effect on cVA perception and attraction (Lebreton et al 2015, Das et al 2017, Cazale-Debat et al 2019.…”

Specific mate communication and recognition underlies reproduction and hence speciation. Mate communication evolves during adaptation to ecological niches and makes use of social signals and habitat cues.Our study provides new insights in Drosophila melanogaster premating olfactory communication, showing that female pheromone (Z)-4-undecenal (Z4-11Al) and male pheromone cVA interact with food odour in a sex-specific manner. Furthermore, Z4-11Al, which mediates upwind flight attraction in both sexes, also elicits courtship in experienced males.Twin variants of the olfactory receptor Or69a are co-expressed in the same olfactory sensory neurons, and feed into the same glomerulus in the antennal lobe. Z4-11Al is perceived via Or69aB, while the food odorant (R)-linalool is a main ligand for the other variant, Or69aA. That Z4-11Al mediates courtship in experienced males, not (R)- linalool, is probably due to courtship learning. Behavioural discrimination is reflected by calcium imaging of the antennal lobe, showing distinct glomerular activation patterns by these two compounds.Male sex pheromone cVA is known to affect male and female courtship at close range, but does not elicit upwind flight attraction as a single compound, in to contrast to Z4-11Al. A blend of cVA and the food odour vinegar attracted females, while a blend of female pheromone Z4-11Al and vinegar attracted males instead.Sex-specific upwind flight attraction to blends of food volatiles and male and female pheromone, respectively, adds a new element to Drosophila olfactory premating communication and is an unambiguous paradigm for identifying the behaviourally active components, towards a more complete concept of food-pheromone odour objects.SummaryThe female-produced, species-specific volatile pheromone of D. melanogaster attracts both sexes from a distance, alone and in concert with food odorants, and elicits courtship in experienced males.
