Coordinated changes in JH biosynthesis and JH hemolymph titers in Aedes aegypti mosquitoes.

ABSTRACT: Juvenile hormone III (JH) is synthesized by the corpora allata (CA) and plays a key role in mosquito development and reproduction. A decrease in JH titer during the last instar larvae allows pupation and metamorphosis to proceed. As the anti-metamorphic role of JH comes to an end, the CA of the late pupa once again synthesizes JH, which plays an essential role in orchestrating reproductive maturation. In spite of the importance of Aedes aegypti as a vector, a detailed study of the changes of JH hemolymph titers during the gonotrophic cycle has never been performed. In the present studies, using a high performance liquid chromatography coupled to a fluorescent detector (HPLC-FD) method, we measured changes in JH levels in the hemolymph of female mosquitoes during the pupal and adult stages.
