Caloglyphus (=Sancasania) polyphyllae discharges from a pair of opisthonotal glands a characteristic set of volatiles, i.e. three monoterpenes and seven hydrocarbons. Among them, β-acaridial, which is known as the female sex pheromone of the species and has antifungal activity, was newly identified as the aggregation pheromone for unfeeding and unmating mites. Feeding mites, however, exhibited sexually aroused behavior instead of the tendency to cluster when exposed to β-acaridial. This is the first example of the compound demonstrating two pheromone functions depending upon the circumstances faced by the mites.
Caloglyphus(=Sancasania)polyphyllae从一对乳头状腺体中排出一组特征性的挥发性物质,即三种单萜和七种
碳氢化合物。其中,β-aridial 是该物种的雌性信息素,具有抗真菌活性。然而,进食的螨虫在接触到β-aridial时表现出性兴奋行为,而不是聚集倾向。这是该化合物根据螨虫所面临的环境而表现出两种信息素功能的第一个实例。
