Some synthetic analogues of insect juvenile hormone cause tremendous rise of respiratory me­tabolism in the last larval instar of Dermestes maculatus. The O2 consumption values occasionally found in these hypermetabolic larvae (20 ml/g/h) can be classified among the most intensive res­piratory rates ever recorded in living organisms. The phenomenon is directly related to the dose of juvenile hormone activity and it is dependent on nutrition. The mechanism of such specific meta­bolic action of juvenile hormone is based on complete oxidation of the dietary fatty acids, provid­ing metabolic water for larval somatic growth. The excessive amounts of energy created by hy­permetabolism are partly converted to heat, suggesting uncoupling of phosphorylation. Some other specific endocrmological features associated with hypermetabolism have been discussed.

Dysdercus Cardinalis

Cotton stainers (Dysdercus spp.) are members of the family Pyrrhocoridae and many are pests of cotton throughout the tropics. Ten species are found in Africa (Pearson, 1958). Three of these have been established in colonies at Arusha, Tanzania. They are D. cardinalis Gerst., D. fasciatus Sign. and D. nigrofasciatus Stål.

Synthetic Work

Synthetic work leading to the preparation of todomatuic acids (2a), juvabiones (2b), and ar-(±)-juvabione (8d) and the successful conversion of ar-(+)-turmerone (9) to ar-(+)-juvabione (3b) is presented. The synthetic compounds 2b and 3b exhibit juvenile hormone activity.
