用SiO_2柱层析和AgNO_3/SiO_2柱层析，对3660只果蝇的雌雄果皮粗提物进行了生物性信息素活性测定。经过三步层析，得到有效部位。经气-液色谱分析、化学衍生化和气相色谱-质谱分析，确定活性部位的主要成分为(Z，Z)-5，27-三碳二烯[(Z，Z)-5，27-C33：2]。合成的(Z，Z)-5，27-C33：2在5个雌性等价物(FE)上引起了明显的求偶反应，D的求偶指数很高。雄性苍白蚁。因此，(Z，Z)-5，27-C33：2是该种的主要性信息素成分。
A crude cuticular extract from both sexes of 3660 fruit flies (Drosophila pallidosa) was subjected to SiO2 and AgNO3/SiO2 column chromatography, accompanied by bioassay for the sex pheromone activity. After three chromatographic steps, the active fraction was obtained. The main component of the active fraction was determined to be (Z,Z)-5,27-tritriacontadiene [(Z,Z)-5,27-C33:2, on the basis of gas-liquid chromatographic analysis, chemical derivatization and gas chromatography-mass spectrometry. Synthetic (Z,Z)-5,27-C33:2 at 5 female equivalents (FE) elicited a clear courtship response with a high courtship index amongD. pallidosa males. Therefore it was concluded that (Z,Z)-5,27-C33:2 was a major sex pheromone component in this species.
