Ecdysone is the steroidal prohormone of the major insect moulting hormone 20-hydroxyecdysone. It groups with its homologues the steroidal molting hormones in arthropods, but they also occur in other phyla where they can play different roles. Besides ecdysteroids appear in many plants mostly as protection agents (toxins or antifeedants) against herbivorous insects. The important developments and...
In control last-instar larvae of Spodoptera exigua, and Leptinotarsa decemlineata, major hemolymph ecdysteroid peaks appeared around day 3-4, and 8-9, respectively, which is correlated with normal apolysis. Later on, hormone titers declined to a basal level. In Colorado potato beetle last-instars, a small rise was noted around day 4, which represents the time of digging. In last-instar larvae of...
