步行成年西方花蓟马Frankliniella occurentalis（Pergande）（Thysanoptera：Thripidae）的嗅觉生物测定表明，处女女性（1- 3-d postemergence）被吸引到气味的25个成年男性，但不是气味的25个成年女性，提供了行为证据男性产生的性信息素在这个物种。与早期的发现相反，混合年龄的成年男性被成年男性的气味所吸引。对SPME纤维上收集的气味进行GC分析，发现两种主要成分和五种次要成分存在于男性气味中，而不是女性气味中。雄性动物的己烷浸提液中不存在这些化合物，表明这些化合物是按需生产的，未储存。
Olfactometer bioassays of walking adult western flower thrips Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) showed that virgin females (1- to 3-d postemergence) were attracted to the odor of 25 adult males, but not to the odor of 25 adult females, providing behavioral evidence for a male-produced sex pheromone in this species. In contrast to earlier findings, mixed-age adult males were attracted to the odor of adult males. GC analysis of odors collected on SPME fibers revealed two major components and five minor components that were present in the male odor and not in the female odor. The compounds were not present in hexane extracts of males, indicating that these compounds are produced on demand and not stored.
