Aconitase and Developmental EndPointsasEarly IndicatorsofCellularToxicity Induced by Xenobiotics in Drosophila Melanogaster
Background: In this study, the toxicity of the different xenobiotics was tested on the fruit fly Drosophila melanogaster model system. Methods: Fly larvae were raised on food supplemented with xenobioticsat different concentrations (sodium nitroprusside (0.1-1.5 mM), S-nitrosoglutathione (0.5-4 mM), and potassium ferrocyanide (1 mM)). Emergence of flies, food intake by larvae, and pupation h...
متن کاملPredatory cannibalism in Drosophila melanogaster larvae.
Hunting live prey is risky and thought to require specialized adaptations. Therefore, observations of predatory cannibalism in otherwise non-carnivorous animals raise questions about its function, adaptive significance and evolutionary potential. Here we document predatory cannibalism on larger conspecifics in Drosophila melanogaster larvae and address its evolutionary significance. We found th...
متن کاملLethality and Developmental Delay in Drosophila melanogaster Larvae after Ingestion of Selected Pseudomonas fluorescens Strains
BACKGROUND The fruit fly, Drosophila melanogaster, is a well-established model organism for probing the molecular and cellular basis of physiological and immune system responses of adults or late stage larvae to bacterial challenge. However, very little is known about the consequences of bacterial infections that occur in earlier stages of development. We have infected mid-second instar larvae ...
متن کاملThe Nutritional Requirements of Drosophila Melanogaster
Drosophila melanogaster lives naturally on various live yeasts that grow in the presence of bacteria, moulds and other micro-organisms, on decaying organic matter. In the laboratory live or autoclaved yeast is perfectly adequate for development, but media on which live yeasts are growing are very heterogeneous; further, the quantity and quality of the available food changes at successive stages...
