Abstract: Insect double identity is insulin-linked Some types of insect can exist in two forms, both as long-winged morphs that can move from habitat to habitat to follow resources, and as short-winged flightless morphs with high fertility, but the molecular details of this switch have remained unclear. One species that leads this double life is the migratory brown planthopper Nilaparvata lugens, a serious pest in rice-growing regions of Asia. Chuan-Xi Zhang and colleagues show that long-wing versus short-wing development in N. lugens is controlled through the opposing effects of two insulin receptors, InR1 and InR2, on the activity of the forkhead transcription factor Foxo.
