Action d'une alimentation a base de feuilles d'olivier [olea europea] sur la biosynthesis in vitro de la JH III par les corpora allata chez shistocerca gregaria au cours de la vitellogense

Per os administration of olive leaves [Olea europea] to females of Schistocerca gregaria results in stopping vitellogenesis. These vitellogenins are not synthesized by the fat body in the heamolymph. The vitellogenin inhibition is induced by the stopping of juvenile hormone JH III by the corpora allata. These corpora allata [Medicago sp.] synthesise 10 times less JH III than those of alfalfa fed females
