چکیده
Epidermis, Tenebrio molitor L., target organ function, juvenile hormone receptor In v ivo tests give evidence that the epidermis is the target organ for the juvenile hormone of insects. A study of the distribution of injected 10,ll-epoxy-6,7-trans-2,3-trans-farnesylpropenylether and of its metabolic products in epidermis, lymphae, and other organs demon strated that the unaltered ether accumulates in and is more slowly metabolised there than in the

A novel putative insect chitinase with multiple catalytic domains: hormonal regulation during metamorphosis.
We have used differential display to identify genes that are regulated by juvenile hormone in the epidermis of the beetle Tenebrio molitor. One of the genes encodes T. molitor chitinase 5 (TmChit5), a chitinase possessing an unusual structure. Sequence analysis of TmChit5 identified five 'chitinase units' of approx. 480 amino acids with similarity to chitinase family 18. These units are separat...
متن کاملMechanism of gene expression in Tenebrio molitor. Juvenile hormone determination of translational control through transfer ribonucleic acid and enzyme.
Experiments presented here suggest that control of gene expression mediated by juvenile hormone is at the translational level and involves the appearance of a new transfer RNA and its activating enzyme. The evidence is as follows. Topical application of juvenile hormone to 1st day pupae of Tenebrio molitor caused a second pupal molt after 7 days, instead of an adult molt. Ribosomes isolated fro...
متن کاملEffects of dietary replacement of fishmeal by yellow mealworm (Tenebrio molitor) larvae meal on growth performance, hematological indices and some of non-specific immune responses of juvenile rainbow trout (Oncorhynchus mykiss)
8-week feeding trial was conducted for juvenile rainbow trout (Oncorhynchus mykiss) to determine the optimal amount of Tenebrio molitor meal (TM) that could replace fishmeal in feeds without reducing growth performance, hematological indices and non-specific immune responses. Five isonitrogenous and isolipidic diets were formulated with TM replacing 0% (Control), 25% (TM25), 50% (TM50), 75% (TM...
متن کاملEffects of juvenile hormone, ecdysterone, actinomycin D, and mitomycin C on the cuticular proteins of Tenebrio molitor.
Juvenile hormone (JH), ecdysterone and some antibiotics cause Tenebrio molitor to form a second pupa or pupal-adult intermediate. Incorporation of labelled leucine into the cuticular proteins of JH-induced second pupae did not differ from incorporation in normal pupae, and the soluble cuticular proteins from these young second pupae were indentical to those extracted from normal pupal exocuticl...

W ith the help of radioactive dilution analysis allowing the qualitative and quantitative deter mination of all three presently known juvenile hormones (JH-1 to 3) the following seven species of four orders were investigated in the adult stage: Coleoptera: Tenebrio molitor, Leptinotarsa decemlineata; O rthoptera: Schistocerca gregaria; B lattodea: Blatt a orientalis, Leucophaea maderae, Naupho...
