Central to this process is the eclosion hormone (EH), a neurohormone that plays a pivotal role in initiating and regulating the complex sequence of events leading to successful molting in holometabolan species. Very little information is available in Hemimetabola, which display a different kind of development characterized by gradual changes. This paper reports on the identification of the two EH precursors and the EH receptor (EHR), a guanylyl cyclase, in a hemimetabolan pest species, the desert locust, Schistocerca gregaria. Using qRT-PCR, an in-depth profiling study of Schgr-EH-1, −2 and Schgr-EHR transcripts was performed. Silencing of Schgr-EH-1, −2 and Schgr-EHR resulted in lethality at the expected time of ecdysis, thereby showing their crucial role during this process.Essential role of eclosion hormone precursor and receptor genes in desert locust ecdysisJournal article10.1016/j.jinsphys.2024.104736WOS:001373624100001EXPRESSIONSILKWORMSEQUENCEBEHAVIORRELEASENEURONSMEDLINE:39622467
