Visual navigation of a virtual blowfly
… of this thesis. Like many other animals, the blowfly exploits the optic flow, a characteristic pattern of image movements on the eye, as an important source of information. The neuronal circuits analysing these image movements in the brain of blowflies are well known. This thesis presents a …

Isolating and characterizing antimicrobial peptides derived from larvae of the blowfly Sarconesiopsis magellanica (diptera: Calliphoridae)
Larval therapy (LT) is an alternative treatment which uses fly larvae to heal chronic wounds; its action is based on debridement, bacterial removal and stimulating granulation tissue. The most important mechanism for fighting infection with LT depends on larval excretions and secretions (ES). The …

The analysis of the artefacts produced by forensically significant blowfly (Diptera: Calliphoridae) activity and their effect on bloodstain pattern analysis
Violent crimes involving bloodshed may result in bloodstains spattering on the surrounding surfaces. Accurate analysis of bloodstains at the scene can provide investigators with insights into the series of events that occurred during the execution of a violent crime. At a crime scene, blowflies …

Arthropod successionin Whitehorse, Yukon Territory and compared development of protophormia terraenovae (R. -D.) from Beringia and the Great Lakes Region
… compare the development rates of the dominant blowfly species (Protophormia terraenovae R.-D.) to another population collected in Oshawa, Ontario. Decomposition in Whitehorse occurred at a much slower rate than is expected for the summer season, and the singularly dominant blowfly species is …

Conditioning and retention, as studied in a behavior-genetic analysis of the blowfly Phormia regina: A search for relationships between learning and memory
Using proboscis extension (unconditioned response) to sucrose (unconditioned stimulus), individual blowflies (Phormia regina) were classically conditioned to saline (conditioned stimulus). Directional and stabilizing selection for retention and conditioning, respectively, have bred two strains of …

Advances in solid phase microextraction for the analysis of volatile compounds in explosives, tire treatments, and entomological specimens
… method was developed for the analysis of blowfly (Diptera) liquid extracts. In the fifth and final project, the new method was put to the task of performing a chemotaxonomic analysis on pupa specimens, seeking to chemically characterize them according to their age, generation, and …

Identification of morphologically similar species of necrophagous flies (diptera: calliphoridae) in Oklahoma : reliability and application of techniques in a forensic setting.
… and genetic identification of three blowfly species (Lucilia cuprina, Lucilia sericata, and Lucilia mexicana) sampled from eight different locations within Oklahoma and one island location off of the coast of New Hampshire. A 308 basepair amplicon within the cytochrome oxidase I gene …

A single AKH neuropeptide activating three different fly AKH-receptors: an insecticide study via computational methods
… all have the same AKH that is present in the blowfly, Phormia terraenovae; this AKH has the code-name Phote-HrTH. Binding of the AKH to the extracellular binding site of a G protein-coupled receptor causes its activation. In this thesis, the structure of Phote-HrTH in SDS micelle solution was …

Electrophysiological and morphological analyses in two species of insects, Protophormia terraenovae and Ceratitis capitata
… generator in the labellar taste receptors of the blowfly is differently affected by 4-aminopyridine and 5-hydroxytryptamine In taste chemoreception of invertebrates the interaction of taste stimuli with specific membrane receptors and/or ion channels located in the apical membrane of taste …

From Microarrays to Behavior: Genes Controlled by Feeding State in Mosquitoes and Flies
… intake remains largely unknown. Insects like the blowfly and the locust have classically been used to describe basic features of feeding behavior (Bernays and Chapman, 1974; Dethier, 1976). These animals, as well as vinegar flies and mosquitoes have been shown to modify their feeding behavior …

Neural processing of chemosensory information from the locust legs
… The classic work of Dethier on the blowfly, showed that chemical stimulation of the tarsi of Phormia regina led to proboscis extension, which was necessary to allow subsequent stimulation of additional chemoreceptors on the labellum and oral papillae, which finally led to drinking. …

Signalkaskaden und Steuermechanismen in den Speicheldrüsen von Dipteren
Flüssigkeitssekretion und Proteinsekretion werden in Speicheldrüsen von Insekten über Hormone und Neurotransmitter gesteuert. Diese entfalten ihre physiologische Wirkung in den sekretorischen Drüsenzellen hauptsächlich über den zyklischen Adenosinmonophosphat (cAMP)-Signalweg und den …
