“…Relatively inflexible or innate sexual traits may constitute more reliable cues for species discrimination than socially inherited traits. It remains possible that fruit fly courtship song is influenced by other components of the social environment such as the social environment experienced during the larval stages (Kim, Ehrman, & Koepfer, ), or male–female interactions during adulthood, but our results do not support the idea that intrasexual social experience influences song structure even though it can influence song preferences and responses (Li et al, ). Given the increasingly widespread evidence for plasticity of courtship and reproductive behaviors, it may be important in future studies to consider and test the conditions under which strong sexual trait canalization, rather than plasticity, is predicted and observed.…”

Courtship behavior in Drosophila has often been described as a classic innate behavioral repertoire, but more recently extensive plasticity has been described. In particular, prior exposure to acoustic signals of con‐ or heterspecific males can change courtship traits in both sexes that are liable to be important in reproductive isolation. However, it is unknown whether male courtship song itself is socially plastic. We examined courtship song plasticity of two species in the Drosophila melanogaster subgroup. Sexual isolation between the species is influenced by two male song traits, the interpulse interval (IPI) and sinesong frequency (SSF). Neither of these showed plasticity when males had prior experience of con‐ and heterospecific social partners. However, males of both species produced longer bursts of song during courtship when they were exposed to social partners (either con‐ or heterospecific) than when they were reared in isolation. D. melanogaster carrying mutations affecting short‐ or medium‐term memory showed a similar response to the social environment, not supporting a role for learning. Our results demonstrate that the amount of song a male produces during courtship is plastic depending on the social environment, which might reflect the advantage of being able to respond to variation in intrasexual competition, but that song structure itself is relatively inflexible, perhaps due to strong selection against hybridization.

“…Male courtship during species recognition is likewise affected by previous experience in Drosophila melanogaster, which can learn to reduce courtship towards D. simulans after a period of exposure (Dukas 2004;see Dukas 2006). Exposure during development has also been shown to reduce heterospecific pairings among D. paulistorum subspecies (e.g., Kim et al 1996;Kim and Ehrman 1999). The ability to learn to avoid heterospecific courtship is not universal within Drosophila however; D. pseudoobscura appears unable to learn to avoid to court D. persimilis (Kandul et al 2006).…”

Reinforcement and learning

Evidence has been accumulating to support the process of reinforcement as a potential mechanism in speciation. In many species, mate choice decisions are influenced by cultural factors, including learned mating preferences (sexual imprinting) or learned mate attraction signals (e.g., bird song). It has been postulated that learning can have a strong impact on the likelihood of speciation and perhaps on the process of reinforcement, but no models have explicitly considered learning in a reinforcement context. We review the evidence that suggests that learning may be involved in speciation and reinforcement, and present a model of reinforcement via learned preferences. We show that not only can reinforcement occur when preferences are learned by imprinting, but that such preferences can maintain species differences easily in comparison with both autosomal and sex-linked genetically inherited preferences. We highlight the need for more explicit study of the connection between the behavioral process of learning and the evolutionary process of reinforcement in natural systems.

We have been utilizing members of the Drosophila paulistorum complex of semispecies to study the development of adult discriminatory behavior. In this study, three rearing methods were used to examine the effects of previous exposure to heterosemispecifics on reproductive isolation among the various semispecies. Experimental flies were exposed to heterosemispecifics by one of three methods: exposure to airborne heterosemispecific stimuli from egg through sexual maturity, physical contact with heterosemispecifics only during the postimaginal period, and mixed culturing (total physical contact with heterosemispecific individuals during each of five preimaginal stages). Effects of the first treatment varied with semispecies. The second treatment had no significant effect on mating behavior. The third treatment of mixed culturing reinforced sexual isolation.
