In this work we have characterized and compared chitin sourced from exoskeleton of Tenebrio molitor larvae fed with polystyrene or plastic kitchen wrap combined bran in the ratio 1: 1 only bran. Analysis frass by ATR-FTIR showed very similar spectra confirmed degradation feed components, while analysis verified absence any residue. Deproteinization followed demineralization produced 6.78-5.29 % chitin, showing that (polystyrene wrap) diet resulted heavier insect exoskeleton, but yielded...
Changes in fitness components including larval stage duration, relative growth rate (RGR), and mass of the gypsy moth, Lymantria dispar L. (Lepidoptera: Lymantriidae), were investigated caterpillars fed a synthetic diet with or without cadmium supplement (10, 30, 100, 250 microg Cd/g dry food weight). Morphometric changes large protocerebral dorsomedial A2 neurosecretor neurons, their nuclei electrophoresis profiles brain proteins analyzed 4 instar moths examined diets. The duration fourth...
The effects of tannic acid on mean values and genetic variation in fitness-related traits (mass, relative growth rate) specific activities digestive enzymes (total proteases, -glucosidase lipase), their plasticity, were investigated fifth instar larvae Lymantria dispar L. (Lepidoptera: Lymantriidae) originating from two populations with different host use histories (oak locust-tree).The did not differentiate respect to traits, i.e. adverse similar both populations.However, Robinia larvae,...
Although all ground beetles have pygidial glands homologous in structure and function, there are many differences among species, often significant, terms of chemical composition the secretion morphology gland components. In this paper, two predatory beetle species genus Carabus, namely C. (Tomocarabus) convexus (Procrustes) coriaceus, were subjected to chemical, morphological histological study their glands' secretions. Altogether, three carboxylic acids isolated, reservoir other glandular...
Abstract This study aimed to determine the effect of magnetic fields on antioxidative defense and fitness‐related traits Baculum extradentatum . Following exposure fields, (superoxide dismutase (SOD), catalase (CAT) activities, total glutathione (GSH) content) (egg mortality, development dynamics, mass nymphs) were monitored in nymphs. The experimental groups were: control (kept out influence magnets), a group exposed constant field (CMF) 50 mT, an alternating (AMF) Hz, 6 mT. We found...
Long-term exposure of invertebrate populations to pollution might result in adaptations that must be taken into account when evaluating physiological parameters as biomarkers contamination. In the present study we investigated whether previous gypsy moth, Lymantria dispar L. (Lepidoptera), population affects sensitivity larvae cadmium treatment under laboratory conditions. Our goals current were compare metallothionein (MT) level and non-specific esterase activity including isoform...
In this study we investigated the effects of tannic acid on fitness-related traits in gypsy moth larvae from two differently adapted populations. Thirty full-sib families oak (suitable host plant, Quercus population), and twenty six locust-tree (unsuitable Robinia population) forests were reared artificial diets with or without a 5% supplement. Tannic shortened duration larval development till 4th instar population, decreased mass both Local adaptation was not recorded for any examined...
Increased presence of benzo[a]pyrene in the environment underlines need for development sensitive biomarkers monitoring. Antioxidative enzymes could be used as early-warning signals because their sensitivity and applicability. The activity 2 antioxidative enzymes, superoxide dismutase (SOD) catalase (CAT), were measured midgut tissues fifth instar Lymantria dispar larvae exposed to different concentrations benzo[a]pyrene: ng, 10 20 100 200 2000 ng benzo[a]pyrene/g dry food weight. Larval...
Lipase activity of the gypsy moth (Lymantria dispar L.) was studied by spectrophotometric method using crude homogenate fifth-instar larval midgut tissues as enzyme source and p-nitrophenyl caprylate (pNPC) substrate. A Km value 0.310 mM a Vmax 1.479 U/mg prot. were obtained for this Among various esters tested, maximum caprate. The most active at alkaline pH, with pH 8.2. Decreased detected after preincubation in buffers below 7.0 above unstable room temperature. Ca2+ independent. Its...
