Abstract
The eversible cervical gland (osmeterium) of the caterpillar of the swallowtail butterfly, Papilio machaon, produces a secretion containing isobutyric and 2-methylbutyric acid. The gland is effective in defense against ants. Even when caterpillars were fed on one of three unbelliferous plants (fennel, carrot, parsnip) the secretion contained the same two acids.
摘要
燕尾蝶毛虫的可翻转颈腺（嗅腺）产生一种含有异丁酸和 2-甲基丁酸的分泌物。该腺在防御蚂蚁方面很有效。即使幼虫以三种不具香味的植物（茴香、胡萝卜、欧防风）之一为食，分泌物中仍含有这两种酸。
