Plant and animal studies

Both juvenile hormone (JH) II and JH I have been identified in whole body extracts of the atlas moth, Attacus atlas. In 0–24 hr old adult males, levels of JH II were ∼ 15 ng/g while JH I titers were much lower (∼0.4 ng/g). In keeping with titer data obtained from other Saturniid moths, male animals contained substantially more JH than adult females, which contained <0.1 ng/g of predominantly JH II. Our results are in contrast to a prior study which did not detect any of the known JHs and hinted at the possible existence of a new JH active principle. The levels of JH I plus II we detected in A. atlas can easily account for the amount of biological activity observed in the prior study. Hence, we are confident that JH II and JH I constitute the only JHs of adult A. atlas.
