Responses to sex pheromones are commonly antagonized by pheromone components of closely related species. Pheromone antagonism has not been widely explored for phylogenetically distant species that have completely different pheromone components. Yet, pheromone components of sympatrically occurring species may also interfere with each other even if these species are distantly related. Here, the effects of heterospecific pheromones on electrophysiology (electroantennogram, EAG) and behavioral responses were tested on the diamondback moth Plutella xyloslella (Plutellidae) and two sympatric noctuid moth species, Spodoptera litura and Spodoptera exigua, whose larvae also feed on Brassica crops.

两种同域夜蛾的性信息素对小菜蛾（Linnaeus）的信息素拮抗作用

对性信息素的反应通常会被密切相关物种的信息素成分所拮抗。对于具有完全不同信息素成分的系统发育远距离物种，信息素拮抗作用尚未得到广泛探索。然而，同域存在的物种的信息素成分也可能相互干扰，即使这些物种是远亲。在这里，异特异信息素对电生理学（触角电图，EAG）和行为反应的影响在小菜蛾Plutella xyloslella（小菜蛾科）和两种同域夜蛾物种Spodoptera litura和Spodoptera exigua 上进行了测试，它们的幼虫也以芸苔属作物为食。
