Hypermetabolic Response Induced by Juvenile Hormone Analogues in an Insect
Some synthetic analogues o f insect juvenile hormone cause tremendous rise o f respiratory m e tabolism in the last larval instar o f Dermestes maculatus. The 0 2 consumption values occasionally found in these hypermetabolic larvae (20 m l/g /h ) can be classified among the most intensive res piratory rates ever recorded in living organisms. The phenomenon is directly related to the dose o f ...
متن کاملEffects of juvenile hormone analogues (JHA) on the development of Trypanosoma cruzi.
Juvenile hormone analogues were tested for their lytic activity on Trypanosoma cruzi Chagas, 1909 blood tripomastigotes cultivated in vitro. The results indicated that the carbamate 4 and the phenoxyphenol derivative 1 are considered good candidates for blood sterilization. The compounds were also assayed for inhibition of development of parasites in infected mice showing a moderated degree of ...
متن کاملPTTH--a potential growth activator in silkworm, Bombyx mori L. for enhancing silk production.
In silkworm, prothoracicotropic hormone (PTTH), directly or indirectly controls silk production and spinning activity along with juvenile hormone (JH). An effort was made to exploit the potential of PTTH by indirectly activating silk gland for increasing silk productivity using short chain synthetic analogues of PTTH. The analogy in action was also established using PTTH extracted from the silk...
متن کاملEvaluation of juvenile hormone analogues as rodent feed-through insecticides for control of immature phlebotomine sandflies.
The juvenile hormone analogues methoprene and pyriproxyfen were evaluated as rodent feed-through insecticides for control of immature stages of the sandfly Phlebotomus papatasi Scopoli (Diptera: Psychodidae). The development and survival of P. papatasi second-instar larvae fed faeces from Syrian hamsters, Mesocricetus auratus, that had been fed a diet containing methoprene (0, 9.788, 97.88 or 9...
متن کاملA Photorhabdus Natural Product Inhibits Insect Juvenile Hormone Epoxide Hydrolase
Simple urea compounds ("phurealipids") have been identified from the entomopathogenic bacterium Photorhabdus luminescens, and their biosynthesis was elucidated. Very similar analogues of these compounds have been previously developed as inhibitors of juvenile hormone epoxide hydrolase (JHEH), a key enzyme in insect development and growth. Phurealipids also inhibit JHEH, and therefore phurealipi...
