Abstract
Insects exhibit a remarkable diversity of sex determination systems. Sex determining mechanisms have been extensively analyzed using the genetic model insects, such as Drosophila melanogaster, revealing that insect sex is determined in a cell-autonomous manner. The sexual identity of each cell is governed by the conserved transcription factor Doublesex, while the regulatory mechanisms controlling its expression are species specific. In contrast, our understanding of how environmental factors modulate the sex determination pathway remains limited. In this review, we summarize recent discoveries on the crosstalk between environmental factors and sex determination pathways in the lepidopteran insects and the cladoceran crustaceans, which are closely related to insects. We discuss how the symbiotic bacterium Wolbachia hijacks the host WZ/ZZ sex determination pathway in the lepidopteran Ostrinia furnacalis. In addition, we highlight how males that are genetically identical to females are produced in response to environmental stimuli in the cladoceran crustacean Daphnia magna. Based on these findings, we explore the evolutionary, ecological, and applied implications of the molecular mechanisms underlying environmentally influenced sex determination.
