Adults and nymphs of the Peruvian stick insect Oreophoetes peruana (order Phasmatodea) have a pair of thoracic glands from which they discharge a malodorous fluid when disturbed. The secretion contains a single volatile component, quinoline. Quinoline has not been reported previously from an animal source. The compound proved repellent or topically irritant in assays with ants, spiders, cockroaches and frogs. O. peruana nymphs, at molting, do not extricate the shed cuticular lining of the glands, thereby managing not to lose their secretory supply when they cast their skin. They are able, as a consequence, to discharge secretion even while still teneral after molting.
秘鲁竹节虫Oreophoetes peruana（竹节虫目）的成虫和若虫有一对胸腺，受到干扰时会从中排出一种恶臭液体。分泌物含有单一挥发性成分喹啉。喹啉此前尚未见来自动物源的报道。在对蚂蚁、蜘蛛、蟑螂和青蛙的试验中，该化合物被证明具有驱避作用或局部刺激性。O. peruana若虫在蜕皮时不会抽出腺体脱落的角质层内衬，因此在蜕皮时不会失去其分泌源。结果，它们即使在蜕皮后仍处于嫩弱状态时也能够排出分泌物。
