狭腹蜂亚科的群居蜂产生一种腹部分泌物，用于两种不同的生物学背景。首先，分泌物在幼虫营养中起着重要作用，它作为成虫放置食物以最终被幼虫消耗的基质。其次，在一些物种中，雌性将相同的分泌物涂在筑巢的基底上，在那里它构成了一个粘性屏障，保护未成熟的幼仔免受蚂蚁的捕食。本文首次报道了三种狭腹蜂的蚁卫构造行为。组成这些分泌物的化合物的鉴定也通过气相色谱-质谱法进行。蚁卫和蚁卵分泌物的成分相似，主要成分为饱和和不饱和的长链烃类和醇类。我们进一步证实腹部分泌物的腺体来源是杜福尔腺。这种腺体含有与蚂蚁保卫和幼虫分泌物相同的碳氢化合物，比例也相同。我们讨论了Dufour的腺体分泌的社会生活中的这些黄蜂的基本重要性，通过比较物种和没有蚂蚁警卫的亚科。
Social wasps of the subfamily Stenogastrinae produce an abdominal secretion that is used in two distinct biological contexts. First, the secretion plays an important role in larval nutrition where it serves as a substrate in which food is placed by the adults for eventual consumption by the larvae. Second, in several species, females apply the same secretion to the substrate on which their nests are constructed, where it constitutes a sticky barrier that defends the immature brood from predation by ants. This paper describes for the first time ant guard construction behaviour of three species of stenogastrine wasps belonging to the genera Eustenogaster and Liostenogaster. The identification of compounds making up these secretions was also performed by gas chromatography–mass spectrometry. Ant guards and brood secretions were similar, with saturated and unsaturated long chain hydrocarbons and alcohols as major components. We further confirm that the glandular source of abdominal secretion is the Dufour's gland. This gland contains the same hydrocarbons, and in the same proportions as ant guards and brood secretion. We discuss the fundamental importance of Dufour's gland secretion in the social life of these wasps by comparing species with and without ant guards within the subfamily.
