The male sex pheromone of the cockroachNauphoeta cinerea was isolated from adult sternal glands and identified by gas chromatography-mass spectrometry. This pheromone, which attracts females from a distance, is a multicomponent blend. It is composed principally of three compounds: 3-hydroxy-2-butanone (acetoin), 2-methylthiazolidine, and 4-ethyl-2-meth-oxyphenol. A mixture of synthetic compounds in a ratio of 4∶4∶1 (2700 ng) elicits maximal response and short latency of response by receptive females, similar to that induced by male sternal gland extracts. Tested separately, each compound induces a positive response, but the moving times spent by females are generally longer than with the mixture or extracts. These three volatile compounds also are found in small amounts (about 1/40 of sternal glands) in tergal gland secretions licked by females. Acetoin also is found in the sternal and tergal glands of two closely related speciesLeucophaea maderae andHenschoutedenia flexivitta. The biological relationship of each compound and pheromone blend to behavioral response is discussed.
从成年胸部腺体中分离出的蟑螂 Nauphoeta cinerea 的雄性信息素，并通过气相色谱-质谱法进行了鉴定。这种从远处吸引雌性的信息素是一种多成分混合物。它主要由三种化合物组成：3-羟基-2-丁酮（乙酰基）、2-甲基噻唑烷和 4-乙基-2-甲氧基苯酚。以 4:4:1（2700ng）的比例混合合成化合物，可引起接受雌性的最大反应和最短的反应潜伏期，类似于雄性胸部腺体提取物引起的反应。单独测试时，每种化合物都会引起阳性反应，但雌性花费的移动时间通常比混合物或提取物长。这三种挥发性化合物也在雌性舔食的小背板腺分泌物中少量存在（约胸部腺体的 1/40）。乙酰基也存在于两种密切相关的物种 Leucophaea maderae 和 Henschoutedenia flexivitta 的胸部和小背板腺中。讨论了每种化合物和信息素混合物与行为反应的生物学关系。
