大蠊属成虫触角感觉器官的分布普遍存在两性异形。在4株美洲大蠊中的3株中，成年雄性比雌性具有更多的接触化学感受器。美洲大蠊第4品系、澳洲大蠊、褐大蠊、黑胸大蠊和日本大蠊的嗅觉感受器均未发现明显的两性异形，而大蠊各品系和种的嗅觉感受器均存在两性异形。雄成虫的嗅觉感受器数量几乎是雌成虫的两倍。这些观察结果是一致的行为观察，属内的大蠊依赖于接收的空中信息素的求爱行为的开始。在P.americana中，在接触化学感受器中发现了性二型性，接触刺激在求偶期间释放雄性的全翅抬高显示和呈现。
Sexual dimorphism in the distribution of antennal sense organs is common among adults of the genus Periplaneta. In 3 of the 4 strains of P. americana examined, adult males had more contact chemoreceptors than females. In the 4th strain of P. americana and in P. australasiae, P. brunnea, P. fuliginosa, and P. japonica, no statistically supportable sexual dimorphism of contact chemoreceptors was found. However, in all strains and species of Periplaneta examined, sexual dimorphism was found in the total number and/or density of olfactory sensilla. Male adults had nearly twice as many olfactory sensilla as female adults. These observations are consistent with the behavioral observation that males within the genus Periplaneta rely on the reception of an airborne pheromone for the initiation of courtship behavior. In P. americana, where sexual dimorphism as found in the contact chemoreceptors, contact stimuli release the full wing raising display and presentation in males during courtship.
