社会性的昆虫女王已经进化出了防止与其有性后代竞争的机制。对于红火蚁（Solenopsis invicta）来说，蚁后已经进化出一种引物信息素，这种信息素可以延缓它们有翅膀的生殖女儿的生殖发育。如果这些女儿从女王的影响中移除，大约需要一周的时间才能开始生殖发育;然而，它几乎在交配后立即开始。几十年来，这种二分法一直没有得到成功的研究。在这里，我们表明，雄性火蚁产生酪胺，衍生物的生物胺酪胺，在他们的生殖系统。雄性在交配过程中将酪胺转移到有翅膀的雌性身上，新交配的蚁后将酪胺酶促转化为酪胺。酪胺充斥血淋巴，迅速激活与生殖发育相关的生理过程。酪酰胺仅在大型蚁亚科（Myrmicinae ant subfamily）（6，800种）中发现，我们认为本文所述的生殖发育的复合抑制/解除抑制将适用于该蚁亚科的其他成员。Vander梅尔等人研究了雄性参与火蚁新交配蚁后生殖发育的机制。作者发现，雄性产生酪胺化合物，当在交配过程中转移到雌性时，这些化合物转化为生物活性分子，引发翅膀脱落，卵巢发育和女王信息素的产生。
Social insect queens have evolved mechanisms to prevent competition from their sexual daughters. For Solenopsis invicta, the fire ant, queens have evolved a primer pheromone that retards reproductive development in their winged reproductive daughters. If these daughters are removed from the influence of the queen, it takes about a week to start reproductive development; however, it starts almost immediately after mating. This dichotomy has been unsuccessfully investigated for several decades. Here we show that male fire ants produce tyramides, derivatives of the biogenic amine tyramine, in their reproductive system. Males transfer tyramides to winged females during mating, where the now newly mated queens enzymatically convert tyramides to tyramine. Tyramine floods the hemolymph, rapidly activating physiological processes associated with reproductive development. Tyramides have been found only in the large Myrmicinae ant sub-family (6,800 species), We suggest that the complex inhibition/disinhibition of reproductive development described here will be applicable to other members of this ant sub-family. Vander Meer et al. investigate the mechanisms of male involvement in reproductive development in fire ant newly mated queens. The authors find that males produce tyramide compounds that, when transferred to females during mating, are converted to bioactive molecules that trigger wing loss, ovary development, and queen pheromone production.
