Caloglyphus (= Sancasania) polyphyllae discharges from a pair of opisthonotal glands a characteristic set of volatiles, i.e. three monoterpenes and seven hydrocarbons. Among them, beta-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 beta-acaridial. This is the first example of the compound demonstrating two pheromone functions depending upon the circumstances faced by the mites.
多叶嗜木螨（=桑卡螨属）从背板腺分泌出一组独特的挥发物，即三种单萜和七种碳氢化合物。其中，β-粉螨醛，已知是该物种的雌性性信息素且具有抗真菌活性，最近被鉴定为未取食和未交配螨的聚集信息素。然而，取食的螨在接触β-粉螨醛时表现出性唤起行为而非聚集倾向。这是该化合物根据螨所面临的环境展示出两种信息素功能的首个例子。
