DETERMINATION OF JUVENILE HORMONE TITER IN THE HEMOLYMPH OF PUPAE OF INDIAN SILKWORM, Philosamia cynthia ricini
<正> Juvenile hormone plays an important role in controlling the processes of metamorphosis and reproduction of most insects. There has been a growing amount of research works on the determination of JH titers at various physiological levels in a variety of insect species, yet our knowledge concerning JH titer lags behind that of ecdysteroid titer. The reasons are: (ⅰ) JH titers in most insects seem to be generally quite low, and (ⅱ) it is difficult to separate JH from the lipids that are present in rather large quantities and have similarities in chemical and physical properties.
