The volatiles used by the parasitoid Diadromus pulchellus to find its host, the leek moth, are produced by the bacteria developing in the frass of the host larvae. The origin and the nature of these bacteria were investigated. Samples were taken from healthy leeks and from infested leeks in the field, as well as from the frass of larvae reared in the laboratory either on the host plant or on an artificial diet. The various species of bacteria identified were cultured in the presence of precursors of leek sulphur volatiles and their volatile emissions were analysed. Klebsiella oxytoca and various Bacillus, common decomposers of plant matter, were the principal species producing active volatiles which were alkyl disulphides.
寄生蜂普氏迪亚姬蜂用来寻找其寄主——韭菜蛾的挥发性物质，是由寄主幼虫粪便中生长的细菌产生的。对这些细菌的来源和性质进行了研究。从田间健康韭菜和受侵染韭菜中取样，以及从实验室在寄主植物或人工饲料上饲养的幼虫粪便中取样。将鉴定出的各种细菌在韭菜硫挥发性物质前体存在的情况下进行培养，并分析它们的挥发性排放物。产酸克雷伯菌和各种芽孢杆菌是植物物质的常见分解者，它们是产生活性挥发性物质（烷基二硫化物）的主要菌种。
