Fruit fly sexual behaviour is directly influenced by chemical and non-chemical cues that play important roles in reproductive isolation. The chemical profiles of pheromones and cuticular hydrocarbons (CHs) of eight fruit fly populations of the Andean, Brazilian-1 and Brazilian-3 morphotypes of the Anastrepha fraterculus cryptic species complex originating from Colombia (four populations) and Brazil (four populations) were analysed using two-dimensional gas chromatography with mass spectrometric detection. The resulting chemical diversity data were studied using principal component analyses. Andean morphotypes could be discriminated from the Brazilian-1 and Brazilian-3 morphotypes by means of male-borne pheromones and/or male and female CH profiles. The Brazilian-1 and Brazilian-3 morphotypes were found to be monophyletic. The use of chemical profiles as species- and sex-specific signatures for cryptic species separations is discussed.
果蝇的性行为直接受到化学和非化学信号的影响，这些信号在生殖隔离中起着重要作用。使用二维气相色谱-质谱检测法，分析了源自哥伦比亚（四个种群）和巴西（四个种群）的番荔枝实蝇隐种复合体的安第斯、巴西-1和巴西-3形态型的八个果蝇种群的信息素和表皮碳氢化合物（CHs）的化学特征。使用主成分分析对所得的化学多样性数据进行了研究。通过雄性携带的信息素和/或雄性和雌性的CH谱，可以将安第斯形态型与巴西-1和巴西-3形态型区分开来。发现巴西-1和巴西-3形态型是单系的。讨论了使用化学特征作为隐种分离的物种和性别特异性标志。
