    Notes: Abstract Male-female courtship interactions inDrosophila melanogaster are mediated in part by chemical cues. A comparison of the courtship behaviors of normal and genetically olfaction-deficient (olfD) flies lends strong support to this hypothesis and leads to the following inferences regarding the importance of chemical interchange during courtship. Virgin females respond to male courtship by slowing and finally stopping their movements, which appears to enhance the probability of copulation; (olfD) females are defective in this stopping response and in their receptivity to mating. Males can be stimulated to court by airborne cues from virgin females which are effective over a distance of ca. 5 mm. By comparison, the chemical courtship-stimulating cues from immature flies have little airborne efficacy; immature males appear to stimulate courtship only by contact chemoreception. The genetic upset or removal from courtship interactions of olfactory, visual, and auditory cues (thus leaving contact chemoreception as the probable major means of male-female interaction) results in virtual behavioral sterility.

    Spectral analysis of courtship songs in behavioral mutants ofDrosophila melanogaster (1989)
    Springer
    Behavior genetics 19 (1989), S. 503-528 
    Details
    ISSN: 1573-3297
    Keywords: cacophony mutant ; dissonance mutant ; fruitless mutant ; period mutants ; pulse song ; sine song ; fast Fourier analysis ; acoustic spectra
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Psychology
    Notes: Abstract Spectral analyses were applied to the courtship songs of the mutantscacophony (cac), dissonance (diss), fruitless (fru), andperiod (per), as well as to the double mutantcac diss. Aberrant intervals between song pulses were observed indiss, cac, cac diss, andfru songs,diss males displayed a defect in song hums manifested by an irregular sine wave, although the fundamental frequencies were normal. Sine song frequencies and intrapulse frequencies were aberrant incac diss males. Two per mutant alleles (per o1 andper s) were associated with normal seng pulses and hums. These findings are discussed with regard to the mechanisms of song production and the role of these sounds inDrosophila reproduction.
