Flesh Fly (flesh + fly)
Selected AbstractsSeasonal prevalence of blowflies and flesh flies in Osaka CityENTOMOLOGICAL SCIENCE, Issue 4 2006Shin-Ichiro TACHIBANA Abstract Blowflies (Diptera: Calliphoridae) and flesh flies (Sarcophagidae) were collected using a bait trap in Osaka City between April 1998 and June 1999. Seven species from four Calliphoridae genera and three species from one Sarcophagidae genus were captured. Seasonal fluctuations of captured adults for most blowflies showed a bimodal pattern, having peaks in spring and autumn, whereas all flesh flies were captured between spring and autumn. The sex ratios of captured flies were mostly biased toward females.

[source] A novel hemocyte-specific membrane protein of Sarcophaga (flesh fly)FEBS JOURNAL, Issue 17 2000Shohei Hori Extensive tissue remodeling takes place during metamorphosis of holometabolous insects. It has been shown that hemocytes play crucial roles in the recognition and elimination of apoptotic cells and larval tissue fragments produced during metamorphosis. We report the immunoaffinity purification, cDNA cloning, and characterization of a prepupal hemocyte membrane protein of Sarcophaga (flesh fly) with a molecular mass of 120 kDa. This protein is a novel type I transmembrane protein with 18 repeats of an epidermal growth factor-like domain in the predicted extracellular region. Expression of the protein was restricted exclusively to prepupal hemocytes. This protein is suggested to be a scavenger receptor for tissue remodeling. [source] Eicosanoids mediate the laminarin-induced nodulation response in larvae of the flesh fly, Neobellieria bullataARCHIVES OF INSECT BIOCHEMISTRY AND PHYSIOLOGY (ELECTRONIC), Issue 1 2005Vanessa Franssens Abstract Insects have a highly developed innate immune system, including humoral and cellular components. The cellular immune responses refer to hemocyte-mediated processes such as phagocytosis, nodulation, and encapsulation. Nodulation is considered the predominant defense reaction to infection in insects. Treating third instar larvae of the grey flesh fly, Neobellieria bullata, with laminarin (,-1,3-glucan, a typical component of fungal cell walls) induced nodulation in a dose-dependent manner. This reaction was initiated very soon after injection and reached its maximal response level after 4 h. The nodules were not randomly distributed in the hemocoel, but were concentrated around the crop. The possible role of eicosanoids in this nodulation process was determined by treating larvae with the phospholipase A2 inhibitor, dexamethasone, the cyclooxygenase inhibitor, naproxen, and the lipoxygenase inhibitor, esculetin. Both dexamethasone and naproxen significantly impaired the ability of N. bullata larvae to form nodules in response to laminarin. Supplying dexamethasone-treated larvae with the eicosanoid precursor, arachidonic acid, restored the full response. On the other hand, treating larvae with esculetin did not influence the formation of nodules in response to laminarin. This is the first study that demonstrates the occurrence of a laminarin-induced nodulation response in Diptera. Phospholipase A2 and cyclooxygenase activities, both involved in prostaglandin biosynthesis, appear to play an important role in the regulation of this process. Arch. Insect Biochem.
