The components of the ecdysone receptor, SgEcR and SgRXR, are needed for successful metamorphosis in Schistocerca gregaria.
Some SgEcR/SgRXR knockdown females arrested in the last larval stage, 65% of them initiated vitellogenesis, an adult feature.
SgEcR/SgRXR feeds back on the ecdysteroid biosynthesis process by regulating transcript levels of the Halloween genes.
