An interpretation is given of a number of observations on the chemiotropic behavior ofBactrocera oleae in connection with olive maceration water and the fly's return to the olive groves after the first summer rains. To this end, the headspace of both maceration water and leaf leaching water, simulating rainfall, were examined. In both cases, the presence of ammonia, which is generally known to attract fruit flies (Diptera, Tephritidae), was detected and, for the first time, in addition to other compounds that are inert for the fly, the presence of styrene was also detected. This aromatic hydrocarbon was found to be a strong attractant. It is shown that both ammonia and styrene are products of the metabolism of microbial flora present on the olive and leaf surface.
对橄榄浸渍水中的化学趋向性行为以及在夏季初雨后果蝇返回橄榄林的一些观察结果进行了分析。为此,对浸渍水和模拟降雨的叶片浸提水中的顶空部分进行了检测。在这两种情况下,均检测到了氨的存在,氨通常被认为对果蝇(双翅目,实蝇科)具有吸引力,并且,除了对果蝇惰性的其他化合物外,还首次检测到了苯乙烯的存在。这种芳烃被发现是一种强烈的引诱剂。结果表明,氨和苯乙烯都是存在于橄榄和叶片表面的微生物菌群代谢产物。
