    Development of behavioral competence in youngDrosophila melanogaster adults (1989)
    Springer
    Journal of insect behavior 2 (1989), S. 575-588

    ISSN: 1572-8889
    Keywords: aging ; behavior ; central nervous system ; Drosophila melanogaster ; Diptera

    Notes: Abstract We have monitored the ontogeny of several behaviors performed by young Drosophila melanogasteradults. Very young flies are less active than older flies and are less responsive to gravity, light, an odorant, and sucrose applied to their tarsi. In addition, very young males do not consume sucrose or perform any courtship behaviors in response to virgin females, which provide chemical and visual stimuli to courting males. The rate at which flies become maximally competent to respond to stimuli is a function of the behavior. Sensory and motor deficits are not solely responsible for young flies' inability to respond to the stimuli, which suggests that the central nervous system continues to develop after eclosion.

    A Comparison of Female Postcopulatory Behavior in Drosophila melanogaster and Drosophila biarmipes (1997)
    Springer
    Journal of insect behavior 10 (1997), S. 761-770 
    Details
    ISSN: 1572-8889
    Keywords: Drosophila ; females ; sex appeal ; sexual receptivity ; fecundity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The postcopulatory behavior of Drosophila biarmipes and Drosophila melanogaster females was analyzed and compared. Females from both species were shown to undergo a series of behavioral changes following mating, including significant reductions in both sexual attractiveness and receptivity. However, while both attractiveness and receptivity returned to “virgin-like” levels within a few days in D. melanogaster, D. biarmipes females, which regained their sexual attractiveness within a few days, remained unreceptive to copulation for at least 2 weeks. With respect to fecundity, D. melanogaster females produced more offspring when given opportunities to remate, while D. biarmipes females did not benefit from remating opportunities. These observations suggest that D. biarmipes females may have the ability to store sperm and produce offspring from a single mating over longer periods of time than other drosophilids.

    Identification of acoustic stimuli that mediate sexual behavior inDrosophila busckii (Diptera: Drosophilidae) (1992)
    Springer
    Journal of insect behavior 5 (1992), S. 469-478 
    Details
    ISSN: 1572-8889
    Keywords: courtship song ; Drosophila busckii ; sexual receptivity ; Diptera
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract We have shown that D. busckiimales and females, unlike other drosophilids that have been analyzed in this regard, court and copulate as well in relatively dim red light as they do in bright white light. We have also shown that males and females of this species flutter their wings during courtship and that wing fluttering in both sexes is associated with acoustic stimuli. Wingless males perform vigorous courtship but are incapable of mating, suggesting that females must perceive male song to be receptive to copulation. When they are tested with normal males, wingless females stimulate vigorous courtship, but their copulation frequencies are significantly lower than winged females. This observation suggests that perception of the female's song by either or both sexes facilitates mating.

    Description of sexual behaviors ofDrosophila rajasekari (1989)
    Springer
    Journal of chemical ecology 15 (1989), S. 1423-1432 
    Details
    ISSN: 1573-1561
    Keywords: Courtship ; pheromones ; (Z,Z)-7,11-heptacosadiene ; Drosophila rajasekari ; Drosophila melanogaster ; Diptera ; Drosophilidae
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The courtship behaviors and cuticular hydrocarbons ofDrosophila rajasekari are described. Sexually mature males orient, tap, follow, vibrate their abdomens, extend and vibrate their wings, and attempt copulation during courtship. They perform these behaviors in response to immature and matureD. rajasekari of both sexes, and their courtship activities are facilitated by light. The predominant cuticular hydrocarbon found in both sexes is (Z,Z)-7,11-heptacosadiene (HCD), a compound known to be used as a courtship-stimulating sex pheromone by another fruit fly,D. melanogaster. Therefore, it is not surprising thatD. melanogaster males actively court both males and females from theD. rajasekari stock. However, HCD is apparently not used byD. rajasekari as a courtship-stimulating pheromone since matureD. rajasekari males do not courtD. melanogaster females, which produce large quantities of HCD.

    Courtship of young males is ubiquitous inDrosophila melanogaster (1983)
    Springer
    Behavior genetics 13 (1983), S. 517-523

    ISSN: 1573-3297
    Keywords: Drosophila melanogaster ; courtship ; homosexual behavior
    Source: Springer Online Journal Archives 1860-2000

    Notes: Abstract In eightDrosophila melanogaster stocks, males which are only a few hours old stimulate courtship which is qualitatively and, in many of the stocks, quantitatively indistinguishable from the courtship elicited by virgin females. Although the sex appeal of young males and the extent to which it declines as the males become sexually mature vary somewhat from stock to stock, homosexual courtship appears to be characteristic of the species.

    Selection for increased female sexual receptivity inRaised stocks ofDrosophila melanogaster (1995)
    Springer
    Behavior genetics 25 (1995), S. 303-309 
    Details
    ISSN: 1573-3297
    Keywords: Drosophila melanogaster ; sexual behavior ; sexual selection ; courtship ; female receptivity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Psychology
    Notes: Abstract Two third-chromosome mutations inraised (rsd) stocks, when homozygous, cause the wings ofDrosophila melanogaster adults to be held upright. Males expressing these mutations cannot vibrate their wings to produce the courtship song, which functions to increase female receptivity to copulation. As expected,rsd males are less successful when courting wild-type females. However, females from long-establishedrsd stocks are more receptive to courtship stimuli and mate more readily with bothrsd and wild-type males than do wild-type females. Genetic analysis reveals dominant factors on the X and third chromosomes that, in combination, are responsible for the increased receptivity ofrsd females. These observations suggest that the lack of courtship song inrsd stocks, which would be expected to reduce the vigor of the stock, may have functioned as a selective force, favoring mutations that increased female receptivity. Possible consequences of selection favoring the development of differential female receptivity on speciation are discussed.
