为了了解地中海果蝇的求偶行为和信息素交流，人们付出了巨大的努力；然而，性信息素的成分仍然是一个有争议的话题。影响地中海果蝇行为的新成分的发现将引起基于化学信息素的地中海果蝇控制方法的兴趣。这项工作描述了使用固相微萃取收集的头状实蝇散发的挥发性化合物。挥发性研究是根据实验设计进行的，其中三个因素（性别、年龄和交配状态）被认为与更好地理解化学通讯相关。排放数据通过主成分分析进行处理，这是一种以前未应用于果蝇排放挥发物研究的统计方法。发射模式的表征可能有助于选择在生物测定中进一步研究的化合物，以提高对地中海果蝇行为所涉及的关键化学信息素的了解。
Considerable efforts have been devoted to understanding the courtship behavior and pheromone communication of medflies; however, the sex pheromone composition is still a controversial subject. The discovery of new components affecting medfly behavior would be of interest for medfly control methods based on semiochemicals. This work describes volatile compounds emitted by Ceratitis capitata collected using solid phase microextraction. The volatile study was conducted according to an experimental design with three factors (sex, age, and mating status) assumed to be relevant for better understanding the chemical communication. Emission data were treated by means of principal component analysis, a statistical methodology not previously applied to the study of volatiles emitted by fruit flies. The characterization of emission patterns could be useful for the selection of compounds to be further investigated in biological assays to improve knowledge of the key semiochemicals involved in medfly behavior.
