Drosophila melanogaster; G-protein coupled receptors; adults; agonists; digestive system; invertebrates; larvae; locomotion; signal peptide; structure-activity relationships
Abstract:
... The ability to design agonists that target peptide signaling is a strategy to delineate underlying mechanisms and influence biology. A sequence that uniquely characterizes a peptide provides a distinct site to generate novel agonists. Drosophila melanogaster sulfakinin encodes non-sulfated drosulfakinin I (nsDSK I; FDDYGHMRF-NH2) and nsDSK II (GGDDQFDDYGHMRF-NH2). Drosulfakinin is typical of sulfa ...

Abstract:
... Declines in mitochondrial functions are associated with aging. The combination of 5‐aminolevulinic acid (5‐ALA) and sodium ferrous citrate (SFC) improves mitochondrial functions in cultured cells. In this study, we investigated the effects of dietary supplementation with 5‐ALA and SFC (5‐ALA/SFC) on the healthspan and life span of Drosophila melanogaster. Adult Drosophila fruit flies were fed corn ...

Abstract:
... When a new student first begins to push flies, an immediate skill that must be learned is sorting the sexes. In Drosophila melanogaster several sexually dimorphic characters can be used to readily distinguish males from females including abdominal pigmentation, male sex combs and genital morphology. Another, often-overlooked, sexual dimorphism is adult abdominal segment number. Externally, adult D ...

Drosophila melanogaster; acclimation; adults; ambient temperature; cold stress; eggs; exposure duration; heat; heat tolerance; larvae; males; phenotype; pupae
Abstract:
... Ecotherms adjust their physiology to environmental temperatures. Long‐term exposures to heat or cold typically induce acclimation responses that generate directional, but reversible shifts in thermal tolerance and performance. However, less is known about how short exposure in different life stages will affect the adult phenotype. In the present study, we compared the effects of long‐term temperat ...

Flies were reared in control or leaded medium at various doses and tested for their Pb loads at different stages of development (larvae, eclosion, newly-eclosed adults, and mature adults). Pb loads were tested using Inductively Coupled Plasma Ma ...

Similar to several environmental monitoring studies, the present study used Drosophila melanogaster as a model nontarget organism to explore the interfering effects of an organophosphate (OP) insecticide acephate on insect life cycle parameters. Acephate, a common OP, is readily available in nature from agricultural sources as an environmental contaminant. Along with target pests, nontarget fruit ...

Abstract:
... All insects studied to date show reduced growth rates in hypoxia. Drosophila melanogaster reared in moderate hypoxia (10kPa PO2) grow more slowly and form smaller adults, but the mechanisms responsible are unclear, as metabolic rates are not oxygen-limited. It has been shown that individual fruit flies do not grow larger in hyperoxia (40kPa PO2), but populations of flies evolve larger size. Here w ...

Abstract:
... Adult Drosophila melanogaster locate food resources by using distinct olfactory cues that often are associated with the fermentation of fruit. However, in addition to being an odorous food source and providing a possible site for oviposition, fermenting fruit also provides a physical substrate upon which flies can attract and court a potential mate. In this study, we demonstrate that Drosophila ad ...

Numerous experimental life‐history studies on aging are mainly baised on two classical models—fruit fly Drosophila melanogaster (Meigen) and nematode Caenorhabditis elegans (Maupas)—with relatively little attention given to other organisms with different life‐history characters. Two‐spotted spider mite Tetranychus urticae Koch (Acari: Tetranychidae) differs from many other arthropods in that the f ...

Abstract:
... The cuticle of all insects is covered with hydrocarbons which have multiple functions. Cuticular hydrocarbons (CHCs) basically serve to protect insects against environmental harm and reduce dehydration. In many species, some CHCs also act as pheromones. CHCs have been intensively studied in Drosophila species and more especially in D. melanogaster. In this species, flies produce about 40 CHCs form ...
