[quantitative determination of the infectivity of nuclear polyhedrosis virus dna on honeycomb moth (galleria mellonella) larvae]. | the possibility of using honeycomb moth larvae for titration of nuclear polyhedrosis virus (npv) infectious dna and determinations of transfection effectiveness was studied. honeycomb moth larvae were shown to be a sensitive system for npv dna titration. deae-dextran used as a protector increased npv dna infectivity 1000-fold, ld50 in this instance being 2 x 10(8) molecules per larva. the method of npv dna infectivity determinations by the number of larvae with polyhedreae in the fatty tissue is ... | 1980 | 7001752 |
[a non-damaging procedure for dna isolation from insect cell nuclei]. | a gentle procedure is described for dna isolation from galleria mellonella cell nuclei. nuclei lysis was performed by sds in final concentration of 3% which was followed by dna extraction from chromatin by a stepwise rise of nacl concentration up to 2.5 m. after removal of nuclei insoluble components by centrifugation the native dna was purified using the hydroxyapatite column. the method proposed provides a higher yield of the native dna as compared with the phenol-detergent method. | 2015 | 7101477 |
juvenoids cause some insects to form composite cuticles. | metamorphosing insects treated with juvenoids may secrete composite cuticles which combine morphological features of two metamorphic stages within the area secreted by an individual epidermal cell. characters found combined were pigmentation, tanning, surface sculpturing, and microtrichiae. neighbouring cells frequently form different types of cuticle. composite cuticles should not be confused with the more common mosaic cuticles, which are composed of discrete areas with different stage-specifi ... | 1982 | 7153697 |
[dynamics of egg maturation in the parasitoid lixophaga diatraeae (diptera, tachinidae) raised in a substitute host, galleria mellonella (lepidoptera, pyralidae)]. | the content of the uterus and ovaries of l. diatraeae (an ovolarviparous tachinid fly) was studied by dissecting 121 females 0 to 25 days old. several size classes of flies (p: small; m: medium; g: big) were used, weighing 10 to 12.5 mg, 12.5 to 13.5 mg, and 13.5 to 16 mg, respectively. the mean number of ovarioles per ovary, correlated to female size, was 12.1 for p as against 12.9 for m + g females. the total mean number of eggs and oocytes changed with female age and weight. for 0, 5, 10 and ... | 1982 | 7156496 |
calcium content and distribution in egg vesicles of galleria mellonella (lepidoptera) as determined by x-ray microanalysis. | in egg vesicles of galleria mellonella (lepidoptera) electron microprobe analysis reveals calcium in concentrations of 9 and 3 mmoles per 1,000 g tissue wet weight in oocyters and accompanying trophic cells, respectively. this high average level of calcium characterizes both pre- and postvitellogenic oocytes, but the distribution of calcium is not uniform. in postvitellogenic vesicles the central area of the ooplasm shows a higher content of ca than peripheral one, what may be correlated with th ... | 1980 | 7190558 |
new insecticidal cyclodepsipeptides from the fungus isaria felina. i. production, isolation and insecticidal properties of isariins b, c and d. | three new cyclodepsipeptides related to the previously described isariin were isolated from a strain of isaria felina. they were named isariins b, c and d. isariin d and, to a lesser extent, isariin c, exhibited insecticidal activity against galleria mellonella larvae, whereas isariin b and isariin itself proved inactive. | 1981 | 7198111 |
tests with inactivated cricket paralysis virus as a possible immunogen against a virus infection of galleria mellonella larvae. | the antibody-binding capacity of cricket paralysis virus was only slightly reduced by inactivation with heat or formaldehyde. however, galleria mellonella larvae vaccinated with such inactivated cricket paralysis virus preparations and subsequently challenged with live homologous virus were not protected. | 1980 | 7203971 |
effect of disulfiram on the ultrastructure of the peptidergic and aminergic cells in the pars intercerebralis of galleria mellonella (lepidoptera). | injection of disulfiram, a specific inhibitor of noradrenaline synthesis, evokes changes in two different types of neurons in the brain of galleria mellonella: neurones containing dense-core vesicles (60-80 nm) and peptidergic cells containing 180-200 nm neurosecretory granules. the lowering of the electron density of the dense-core vesicles of 60-80 nm seems to be directly connected with disulfiram administration, while the decrease of the amount of neurosecretory material in the neurosecretory ... | 1981 | 7214484 |
ultrastructural study of the postembryonic development of the neural lamella of galleria mellonella l. (lepidoptera). | the neural lamella encapsulating the brain of the wax moth galleria mellonella develops from a very thin (80-120 nm) layer in the first larval instar, resembling the basal lamina, to a thick (1-4 micrometer) sheath composed of two zones in the seventh (last) instar. after its breakdown at the time of larval-pupal ecdysis the neural lamella is reconstructed in the pupa, 2-3 days before pupal-adult ecdysis. the cells of the perineurium seem to be responsible for the formation of the neural lamella ... | 1981 | 7237538 |
