Natural and Synthetic Materials with Insect Hormone Activity. 5. Specific Juvenile Hormone Effects in Aliphatic Sesquiterpenes.
The juvenile hormone activity of ethyl or methyl esters of aliphatic sesquiterpenic acids with 0 to 4 double bonds was tested on 8 species of insects belonging to 5 families of Hemiptera and Coleoptera. Special attention was paid to the addition of hydrogen chloride or epoxide groups on or across the double bonds. Certain chemical changes in the molecule appear to cause a general increase of th...
متن کاملSex pheromone production and reproductive behaviour in gamma-irradiated Tenebrio molitor.
Studies to determine the effects of gamma-radiation on sex pheromone production in female Tenebtio molitor showed that irradiation of females either as newly emerged or as pharate adults with 3.5 or 7 krad had no significant effect on their sex pheromone activity when compared to that of normals. However, treatment of irradiated insects with a juvenile hormone analogue increased their pheromone...
متن کاملThe effects of short-term growth hormone (somatotropin) bath on some growth and immunity indices in the early stages of growth in rainbow trout (Oncorhynchus mykiss)
This study was conducted to determine the effect of growth hormone on some growth and immunity parameters at three stages of rainbow trout eyed egg, alvin and fry. The experiment was carried out in 4 treatments with concentrations of 0, 0.1, 0.5 and 1 mg/l of somatotropin hormone. For permeability, different experimental groups were treated with sodium hypochlorite (0.005 %) for 15 seconds befo...
متن کاملHypermetabolic 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 کاملMolecular and functional characterization of a juvenile hormone acid methyltransferase expressed in the corpora allata of mosquitoes.
A juvenile hormone acid methyltransferase (JHAMT) was isolated as an abundant EST in a library of the corpora allata of the adult female mosquito Aedes aegypti. Its full length cDNA encodes a 278-aa protein that has 43% amino acid identity with BmJHAMT, a juvenile hormone acid methyltransferase previously cloned from Bombyx mori. Heterologous expression produced a recombinant protein that metab...
