Abstract

Male-male courtship is infrequent among mature adult Drosophila melanogaster. After pairs of mature adult males expressing a temperature-sensitive allele of the ecdysone receptor (EcR) gene were treated at a restrictive temperature, however, they engaged in elevated levels of male-male courtship. EcR-deficient males courted wildtype males and females, but were not courted by wildtype males. These results suggest that the ecdysone steroid hormone system may have a role in courtship initiation by adult male fruit flies.

摘要

在成熟的成年黑腹果蝇中，雄雄求偶行为并不常见。然而，对表达蜕皮激素受体（EcR）基因温度敏感等位基因的成年雄蝇对在限制温度下进行处理后，它们的雄雄求偶行为水平有所提高。EcR基因缺陷的雄蝇会向野生型雄蝇和雌蝇求偶，但不会受到野生型雄蝇的求偶。这些结果表明，蜕皮激素类固醇激素系统可能在成年雄性果蝇求偶行为的启动中发挥作用。
