昆虫雄性附属腺（MAG）是负责精液成分合成和分泌的内生殖器官，在雄性生殖策略中发挥着关键作用。在许多昆虫物种中，MAG 产品的有效射精对于雄性繁殖至关重要。为此，果蝇的 MAG 细胞进化出了双核，这导致腺上皮的高可塑性，导致射精精液量的增加。然而，这种双核策略仅在双翅目昆虫（包括果蝇）中零星观察到。在这里，我们报告了常见臭虫 Cimex lectularius 的 MAG 中双核的发现，该臭虫属于半变态半翅目，在系统发育上远离全变态双翅目。在 Cimex 中，双核过程中的细胞形态和同步时间与果蝇有很大不同。此外，在果蝇中，成虫阶段两个细胞核的位置会因交配历史或营养条件而发生变化。然而，它在 Cimex 中保持稳定。这些差异表明 CimexMAG 中的双核在雄性生殖系统中发挥着与果蝇不同的独特作用。
The insect male accessory gland (MAG) is an internal reproductive organ responsible for the synthesis and secretion of seminal fluid components, which play a pivotal role in the male reproductive strategy. In many species of insects, the effective ejaculation of the MAG products is essential for male reproduction. For this purpose, the fruit flyDrosophilahas evolved binucleation in the MAG cells, which causes high plasticity of the glandular epithelium, leading to an increase in the volume of seminal fluid that is ejaculated. However, such a binucleation strategy has only been sporadically observed in Dipteran insects, including fruit flies. Here, we report the discovery of binucleation in the MAG of the common bed bug,Cimex lectularius, which belongs to hemimetabolous Hemiptera phylogenetically distant from holometabolous Diptera. InCimex, the cell morphology and timing of synchrony during binucleation are quite different from those ofDrosophila. Additionally, inDrosophila, the position of the two nuclei in the adult stage changes as a result of the mating history or the nutrient conditions; however, it remains stable inCimex. These differences suggest that binucleation in theCimexMAG plays a unique role in the male reproductive system that is distinct from that ofDrosophila.
