Abstract
Implantation of additional corpora allata (CA) into the last instar larvae of Corcyra cephalonica resulted in the production of extra larval instars, larval-pupal intermediates and adultoid larvae. Moths metamorphosed from the extra larval instars were externally normal.
The juvenoid, hydroprene, when given to last instar larvae, prolonged the larval life span, induced extra larval moult and the moths metamorphosed from such larvae were larvoid adults. Extra pupal instars were produced when this juvenoid was applied to early pupae. Moths obtained after pupal treatment were adultoids. Another juvenoid, methoprene, prolonged larval life and produced giant larvae without extra moult. Incompletely moulted extra larval instars, larval-pupal intermediates and adultoid larvae were formed. Moths obtained after both larval and pupal treatments were externally normal. The percentage of moths obtained after the application of both the juvenoids was small.
The antiallatotropin, precocene II, had no creditable effect on the duration of larval or pupal life. Application to both larvae and pupae, pretreated with hydroprene, largely minimized the hydroprene-induced effects. Pupal treatment, however, produced pupal-imaginal intermediates. The moths obtained from precocene-treated larvae or pupae, with or without juvenoid pretreatment, were externally normal.
