Ropalidia marginata是一种在印度半岛发现的真正的社会性黄蜂。与典型的纯社会性物种不同，它们有温顺的蜂王，不能利用攻击来维持生殖垄断。最近的研究使用化学分析和生物测定表明，杜福尔的腺是一个来源的女王信息素在这个物种。蚁后似乎通过它们的杜福氏腺化合物向工蚁发出信号，可能是通过将它们涂在巢穴表面，这导致了工蚁的繁殖受到抑制，导致了蚁后的生殖垄断。杜氏腺被发现含有饱和的长链烃，最近被认为是Hytera生育信号的祖先状态。Dufour的腺体组成显着不同的皇后和工人之间，也与卵巢发育的状态，不断变化的卵巢发育的功能，从而倡导诚实的皇后信息素。这阐明了通过Dufour腺化合物的信息素女王信号传导维持真社会性的机制。
Ropalidia marginata is a primitively eusocial (truly social) wasp found in peninsular India. It is different from the typical primitively eusocial species in having docile queens that cannot use aggression to maintain reproductive monopoly. Recent studies using chemical analysis and bioassays indicate that Dufour’s gland is a source of the queen pheromone in this species. Queens appear to signal their presence to workers through their Dufour’s gland compounds, possibly by applying them on the nest surface, and this results in suppression of reproduction by workers, resulting in reproductive monopoly by the queen. The Dufour’s gland was found to contain saturated long chain hydrocarbons, which have recently been suggested to be the ancestral state of fertility signals in Hymenoptera. The Dufour’s gland composition differed significantly between queens and workers, and was also correlated with the state of ovarian development, varying continuously as a function of ovarian development, thereby advocating the honesty of the queen pheromone. This elucidates the mechanism of maintenance of eusociality through pheromonal queen signalling by the Dufour’s gland compounds.
