可用于功能遗传学研究的昆虫种类正在迅速增加，这为发育和进化生物学提供了许多新的研究机会。全变性昆虫在动物多样性中所占比例不成比例，因此很好地定位于为各种发育过程提供模式物种。在这里，我们讨论了新兴的全变形模型，并回顾了一些最近的突破。例如，果蝇和蠓被发现使用结构上不相关的远程模式组织者，蝴蝶和飞蛾在卵发生过程中揭示了广泛的模式形成，面粉甲虫的新成像可能性显示了胚胎如何从胚胎外膜中脱离出来，以及在nasoniawasps中发现了控制物种间头部形状差异的复杂遗传学。
The number of insect species that are amenable to functional genetic studies is growing rapidly and provides many new research opportunities in developmental and evolutionary biology. The holometabolous insects represent a disproportionate percentage of animal diversity and are thus well positioned to provide model species for a wide variety of developmental processes. Here we discuss emerging holometabolous models, and review some recent breakthroughs. For example, flies and midges were found to use structurally unrelated long-range pattern organizers, butterflies and moths revealed extensive pattern formation during oogenesis, new imaging possibilities in the flour beetleTribolium castaneumshowed how embryos break free of their extraembryonic membranes, and the complex genetics governing interspecies difference in head shape were revealed inNasoniawasps.
