Summary: Despite natural selection, same-sex sexual attraction is common across animals. This study reveals that the proto-oncogene Myc inhibits male-male courtship in fruit flies by acting in dopaminergic neurons. This finding highlights the crucial roles of genetic factors in inter-male sexual behavior.

Summary: This study finds that Drosophila melanogaster females display aggression toward mating pairs, which is regulated by mating status and perception of mating opportunities. It also relies heavily on olfaction and the combination of food odor and OR47b-dependent fly odor sensing.

Summary: Research shows that courtship song in male fruit flies not only prompts female receptivity, but also suppresses females' escape responses.

Summary: The study revealed that the courtship behavior in male fruit flies is mediated by specific neurons, which respond to multimodal sensory stimuli and lead to a fixed sequence of behaviors. Furthermore, male flies are able to suppress or promote their courtship actions by receiving specific olfactory stimuli through neurons when in contact with females.

Summary: Reproductive behaviors in Drosophila melanogaster are controlled by fruitless neurons. Single-cell RNA sequencing on pupal neurons revealed sex-specific gene expression patterns, with over 113 distinct clusters identified. Marker gene analyses showed enrichment of specific functional groups, including circadian clock neurons, mushroom body Kenyon cells, neurotransmitter-producing neurons, and those expressing doublesex. The presence of both male and female neurons in most clusters suggests common gene expression programs, with sex-specific differences overlaying these programs to generate diverse behaviors.

Summary: Drosophila courtship studies have revealed principles of the neurogenetic organization of complex behavior. Intense light not only enhances courtship towards females but also induces unexpected courtship behaviors among male flies. The innate male courtship behavior is restrained by olfactory cues but can be unleashed by strong visual stimulation in Drosophila.

Summary: The brain integrates multiple information sources during courtship to make a final decision on mating, with research on this complex behavior being conducted through genetic manipulation and analyses in Drosophila model experimental system. While much knowledge has been accumulated on genes and neural circuits controlling sexual behaviors in male flies, research progress on mechanisms in female flies has been slower. Focus is given in this review to pre-mating behavior in female Drosophila melanogaster, exploring the neural and molecular mechanisms behind sensory integration and behavior expression towards courting males.

Summary: The neuropeptide pigment-dispersing factor (Pdf) plays a critical role in regulating circadian rhythms in various insects, including the fruitfly Drosophila melanogaster. Recent studies have shown that Pdf is not only involved in circadian rhythm regulation but also in innate and learned behaviors in Drosophila. This mini-review focuses on the importance of Pdf signaling and Pdf-producing neurons in consolidating and maintaining long-term memory induced by courtship conditioning in Drosophila, as well as the mechanisms of courtship memory processing through Pdf-producing neurons.

Summary: Male-biased operational sex ratios increase male-male competition and select for increased pre- and postcopulatory male success. In this study, we found that males evolved under male-biased sex ratios had higher mating success and courtship frequency compared to females evolved under female-biased sex ratios. Female mating status also influenced male mating success.

Summary: Protein phosphorylation plays a crucial role in sexual development and behavior. This study identified 13 kinases involved in sexual development in Drosophila, with PKA and CASK promoting female sexual behavior. Understanding how kinases regulate neuronal development and physiology provides insights into the robustness of sexual behaviors.

Summary: Africa and Asia are currently facing the worst desert locust plague in decades, with favorable environmental conditions due to exceptionally high rainfall. Research shows that components of the juvenile hormone signaling pathway play a crucial role in male locust reproductive physiology, indicating their potential as molecular targets for pest control.

Summary: The integration between chemosensory cues detected in the nose and hormonal status is not fully understood. However, research on olfactory sensory neurons in mice reveals that the pituitary hormone prolactin can modulate responses to specific chemosensory cues, linking hormonal status with behavioral responses.

Summary: This study compares male morphological characters, pigmentation intensity of male wing spots, wing-scissoring behavior, courtship songs, and reproductive isolation between two species of Drosophila. It finds significant differences in these aspects between D. nepalensis and D. trilutea, with D. nepalensis exhibiting stronger pigmentation, more elaborate scissoring behavior, and specific song types during courtship.

Summary: The evolution of sexual signals is influenced by whether one or both sexes engage in mate choice. In the case of the noctuid moth Chloridea virescens, both males and females emit sex-specific pheromones, but females tend to choose larger males for mating. Female mate choice in this moth species is not influenced by male pheromones, and females use behavior and tactile stimuli to make decisions during courtship.

Summary: Xenophallus umbratilis is a freshwater livebearing fish that shows unique asymmetry in male gonopodium. There is evidence to suggest that males might exhibit side-biased behavior when mating with females. Two assays were conducted to assess the laterality of mating interactions based on gonopodial morphology. Results showed lateralized mating behavior in males with sinistral gonopodial morphology, but not in males with dextral gonopodial morphology. Additionally, no evidence of lateralized body positioning was found in trials with a single female and five males of the same morphology.
