[Effect of olive leaves (Olea europea) feeding on the in vitro JH III biosynthesis by the corpora allata in Schistocerca gregaria during vitellogenesis].
Per os administration of olive leaves (Olea europea) to females of Schistocerca gregaria results in stopping vitellogenesis. These vitellogenins are not synthesised 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.
