Herbivore-induced plant volatile emission is often considered to be attacker species-specific, but most experimental evidence comes from short lived herbaceous species. In a recent study we showed that black poplar (Populus nigra) trees emit a complex blend of volatiles from damaged leaves when they are attacked by generalist gypsy moth (Lymantria dispar) caterpillars. Minor nitrogenous volatiles were especially characteristic of this blend. Here we show that attack on P. nigra by a beetle species, Phratora vulgatissima (Coleoptera, Chrysomelidae), led to the emission of the same compounds as already observed after caterpillar herbivory, but with striking quantitative changes in the blend. The consequences for attraction of herbivore enemies are discussed.
食草动物诱导的植物挥发性物质排放通常被认为具有攻击者物种特异性，但大多数实验证据来自短命的草本物种。在最近的一项研究中，我们表明，黑杨（Populus nigra）树在受到多食性舞毒蛾（Lymantria dispar）毛虫攻击时，受损叶片会释放出一种复杂的挥发性物质混合物。少量含氮挥发性物质是这种混合物的特别特征。在这里，我们表明，一种甲虫物种——葡萄叶甲（Phratora vulgatissima，鞘翅目，叶甲科）对黑杨的攻击，导致释放出与毛虫取食后已观察到的相同化合物，但混合物中的含量有显著变化。文中讨论了对食草动物天敌吸引力的影响。
