Nonsteroidal moulting hormone agonists: effects on protein synthesis and cuticle formation in Colorado potato beetle larvae
Entomologia Experimentalis et Applicata 93 (1), 1-8
Abstract: Larvae of the Colorado potato beetle, Leptinotarsa decemlineata (Say), that were orally treated with RH-0345 at 0.1 mg l^-1, RH-5849 at 10 and 50 mg l^-1, tebufenozide at 2 g l^-1, and 20-hydroxyecdysone at 2 g l^-1, showed symptoms of premature moulting, followed by inhibition of ecdysis. In addition, fresh weight gain and total protein content were blocked. The effects on haemolymphal and cuticular polypeptides after PAGE were linked with premature, new epicuticle deposition as was observed under the electron microscope. These observations support the concept that the ecdysteroid-mimicking action of the three nonsteroidal molecules is specific.
