Abstract:
At a larval body weight of 15-16 mg, young 3rd-instar Calliphora vicina larvae pass from the obligatory feeding phase, when starvation results in cessation of growth or development, to the facultative feeding phase when starvation leads to subsequent pupariation. During normal larval development the transition from obligatory to facultative feeding phase appears to be independent of 20-hydroxyecdysone but absence (or insufficiency) of the hormone is the likely reason why starved larvae in the obligatory feeding phase fail to pupariate. 20-Hydroxy-ecdysone induces termination of feeding by normal, facultative phase larvae and is the probable signal for larval commitment to pupariation. © 1982.
