| metabolic relevance of selenium in the insect corcyra cephalonica. uptake of 75se and subcellular distribution. | requirement, uptake, and subcellular distribution of na2(75)seo3 in the larvae of the insect c. cephalonica was investigated. that se is well tolerated by c. cephalonica upto an added level of 2 ppm in the diet is suggested by the observed increase in body weight, total protein, and succinate dehydrogenase levels. significant increases in the state 3 respiration ensued with se supplementation up to 2 ppm in the mitochondrial oxidation of d-glycerol 1-phosphate, succinate and nadh, along with con ... | 1994 | 7946914 |
| synthesis of racemic 6,10,14-trimethylpentadecan-2-ol, a pheromone of rice moth and 5,9,13-trimethyltetradecanoic acid, a component of marine sponge from a common intermediate. | a facile synthesis of dl-6,10,14-trimethylpentadecan-2-ol (1) a pheromone component of rice moth, corcyra cephalonica stainton and 5,9,13-trimethyltetradecanoic acid (2) a component of marine sponge, cinachyrella alloclada uliczka, using a common, intermediate, hexahydrofarnesol is accomplished. the salient features for 1 are: grignard coupling of 5 with allylmagnesium bromide and oxymercuration-demercuration whereas for 2 they are: knoevenagel condensation and subsequent hydrogenation. | 1993 | 8087560 |
| in vitro effect of nonsteroidal ecdysone agonist rh 5849 on fat body acid phosphatase activity in rice moth, corcyra cephalonica (insecta). | nonsteroidal ecdysone agonist stimulates acid phosphatase activity in the fat body in vitro cultures obtained from ligated late-last instar larvae of corcyra cephalonica. the agonist also stimulates general protein synthesis. this stimulation is both time as well as dose dependent (up to a dose of 1000 ng of the agonist). however, still higher concentrations (1500-4000 ng) tend to depress the degree of stimulation. | 1991 | 1768263 |
| juvenile hormone mediated dna synthesis during larval development of corcyra cephalonica (insecta). | large amount of dna is synthesized during larval development of corcyra and this is conspicuously seen in the early-last instar. ligation in early-last instar causes a decline in both dna content and dna concentration. radiolabelling studies show a low rate of dna synthesis in isolated abdomens, suggesting that hormonal factors from the anterior half of the larvae play a regulatory role in the dna metabolism. juvenile hormone i (jh-i) treatment of ligated early-last instar stimulates dna synthes ... | 1990 | 2090096 |
| 20-hydroxyecdysone mediated activation of larval haemolymph protein uptake by fat body cells of corcyra cephalonica (insecta) | evidence is presented here to show that 20-hydroxyecdysone is essential for the activation of the larval fat body for differential uptake of larval haemolymph proteins (lhps). by using radiolabelled lhps it is shown that the fat body cells of corcyra cephalonica selectively incorporate lhps during late-larval and prepupal development. fluorographic analysis of the labelled fat body proteins from prepupal stage separated on sodium dodecyl-sulphate polyacrylamide gels suggests that the lhps are se ... | 1990 | 2090095 |
| juvenile hormone inhibits the synthesis of major larval haemolymph proteins in rice moth, corcyra cephalonica. | larval haemolymph proteins (lhp), lhp49 and lhp46 are produced in the penultimate and last larval instars. starvation during the early and mid stage of last instar development prevents the production of both lhps. decapitation in early and mid last instar stimulates lhp synthesis and their concentration in haemolymph increases, while ligation in last instar larvae blocks the production of lhps. application of exogenous jh lowers the synthesis of lhp49 and lhp46 in corcyra. these observations sug ... | 1988 | 3245842 |
| ecdysteroid mediated fat body acid phosphatase activity during larval development of rice moth, corcyra cephalonica (lepidoptera). | 20-hydroxyecdysone (20-he) stimulates acid phosphatase activity in the fat body of ligated late-last instar larvae. this effect is time dependent and the specific activity of enzyme increases significantly in hormone treated insects. 20-he also stimulates general protein synthesis. cycloheximide treatment either in conjunction with 20-he or after hormone treatment blocks the increase in enzyme activity as well as increase in protein content. however, actinomycin d treatment does not alter the en ... | 1988 | 3245841 |
| sex pheromones of rice moth,corcyra cephalonica stainton : ii. identification and role of female pheromone. | laboratory investigations of mating behavior in the rice moth,corcyra cephalonica stainton (lepidoptera: pyralidae; galleriinae) showed that male moths are attracted at short range to live, virgin female moths and to female abdominal-tip extract. volatiles collected from virgin female moths contained one component eliciting an electroantennographic (eag) response from the male moth, and the chemical, spectroscopic, and chromatographic data on this component were consistent with that of synthetic ... | 1987 | 24302328 |
| sex pheromones of rice moth,corcyra cephalonica stainton : i. identification of male pheromone. | behavioral observations of the rice moth (corcyra cephalonica, pyralidae, galleriinae) in the laboratory have shown that a male wing-gland pheromone induces attraction of female moths. this pheromone was identified as a blend of (e,e) and (z,e)-farnesal. wing-gland extracts or synthetic compounds were shown to be attractive to females by inducing walking. | 1987 | 24302327 |
