“…McCall e cols 17 observaram que Anopheles arabiensis retornava ao local onde havia feito o primeiro repasto sanguíneo, propondo que este mosquito seria capaz de uma memorização espacial. Machos de Drosophila mercatorum aprimoraram a habilidade de cortejar as fêmeas em função de experiências anteriores 22 . Charlwood e cols 5 , em estudo com Anopheles farauti, e Renshaw e cols 25 , com Aedes cantans, sugeriram que esses insetos são capazes de memorizar uma determinada área espacial que lhes facilite a circulação nos locais de repasto sanguíneo, repouso e reprodução.…”

Relata-se os resultados de uma investigação sobre a possibilidade da existência de memória em flebotomíneos em área endêmica de leishmaniose tegumentar americana, no Estado do Paraná. Capturaram-se flebotomíneos no Recanto Marista, Doutor Camargo, Estado do Paraná, Brasil, com armadilhas de Falcão, de 15/11/2007 a 26/11/2007, em dois galinheiros (G1 e G2). Foram capturados 2.080 flebotomíneos (1.000 em G1 e 1.080 em G2), que foram marcados e soltos. Nyssomyia neivai foi a espécie mais (90,5%) freqüente. Do total solto, recapturaram-se 168 (8%) flebotomíneos e a recaptura no G2 foi significativa. Os resultados evidenciam que é possível a existência de memória espacial, olfativa e/ou a fidelidade ao hospedeiro e que isto orientem os flebotomíneos no reconhecimento dos locais onde há disponibilidade de fontes de sangue.

“…Previously mated D. mercatorum males have shorter courtship latencies, and the amount of time a male spends courting increases between the first and second matings [29]. In contrast, Kujtan and Dukas [30] demonstrated that D. persimilis males that have mated with a heterospecific female do not have greater heterospecific mating success or altered courtship compared to naïve males or males that previously mated with conspecifics.…”

“…Most of the previously described paradigms investigated behavioral effects of social experiences that did not culminate in mating, but little attention has been directed to understanding how the presumably positive experience of mating affects later courtship behaviors and copulation encounters. Previously mated D. mercatorum males have shorter courtship latencies, and the amount of time a male spends courting increases between the first and second matings [29] . In contrast, Kujtan and Dukas [30] demonstrated that D. persimilis males that have mated with a heterospecific female do not have greater heterospecific mating success or altered courtship compared to naïve males or males that previously mated with conspecifics.…”

“…However, a detailed analysis of male courtship behavior and mating propensity towards conspecifics after a successful bout of mating is still lacking. Since males show behavioral modification based on their current and previous social experiences, including changes in courtship effort that may provide a mating advantage [29] , we hypothesized that D. melanogaster males with prior mating experience would modify their courtship behaviors towards receptive females. One possibility is that sexually experienced males may have decreased mating latencies.…”

Sexual Experience Enhances Drosophila melanogaster Male Mating Behavior and Success

et al. 2014

Competition for mates is a wide-spread phenomenon affecting individual reproductive success. The ability of animals to adjust their behaviors in response to changing social environment is important and well documented. Drosophila melanogaster males compete with one another for matings with females and modify their reproductive behaviors based on prior social interactions. However, it remains to be determined how male social experience that culminates in mating with a female impacts subsequent male reproductive behaviors and mating success. Here we show that sexual experience enhances future mating success. Previously mated D. melanogaster males adjust their courtship behaviors and out-compete sexually inexperienced males for copulations. Interestingly, courtship experience alone is not sufficient in providing this competitive advantage, indicating that copulation plays a role in reinforcing this social learning. We also show that females use their sense of hearing to preferentially mate with experienced males when given a choice. Our results demonstrate the ability of previously mated males to learn from their positive sexual experiences and adjust their behaviors to gain a mating advantage. These experienced-based changes in behavior reveal strategies that animals likely use to increase their fecundity in natural competitive environments.

“…Therefore, it is reasonable to expect that a more experienced male would be better at performing some aspect of courtship to improve his mating success. In support of this idea, Drosophila males experienced at courting females initiate courtship toward novel, receptive females more quickly than do inexperienced males [ 44 , 45 ]. In a natural setting where many flies are competing for mates, rapid courtship initiation may give an experienced male a competitive advantage that increases his mating success.…”

Mating alters gene expression patterns in Drosophila melanogaster male heads

BackgroundBehavior is a complex process resulting from the integration of genetic and environmental information. Drosophila melanogaster rely on multiple sensory modalities for reproductive success, and mating causes physiological changes in both sexes that affect reproductive output or behavior. Some of these effects are likely mediated by changes in gene expression. Courtship and mating alter female transcript profiles, but it is not known how mating affects male gene expression.ResultsWe used Drosophila genome arrays to identify changes in gene expression profiles that occur in mated male heads. Forty-seven genes differed between mated and control heads 2 hrs post mating. Many mating-responsive genes are highly expressed in non-neural head tissues, including an adipose tissue called the fat body. One fat body-enriched gene, female-specific independent of transformer (fit), is a downstream target of the somatic sex-determination hierarchy, a genetic pathway that regulates Drosophila reproductive behaviors as well as expression of some fat-expressed genes; three other mating-responsive loci are also downstream components of this pathway. Another mating-responsive gene expressed in fat, Juvenile hormone esterase (Jhe), is necessary for robust male courtship behavior and mating success.ConclusionsOur study demonstrates that mating causes changes in male head gene expression profiles and supports an increasing body of work implicating adipose signaling in behavior modulation. Since several mating-induced genes are sex-determination hierarchy target genes, additional mating-responsive loci may be downstream components of this pathway as well.
