Mechanistic Connectomics in Drosophila
… now exist for the adult fruit fly, \textit{Drosophila melanogaster}. This thesis develops statistics and analyses for Mechanistic Connectomics using these datasets to analyse the circuit architectures that guide the interactions between innate and learned behaviours. Creating meaningful …

Spotted Wing Drosophila (Drosophila suzukii) in Arkansas: Winter Morphs, Wild Hosts, and Fungal Control
<p>Drosophila suzukii (Matsumura), or spotted wing drosophila (SWD), is an invasive fruit fly pest that was first found in the United States in 2008. Unlike native Drosophila, SWD females have a serrated ovipositor that allows them to attack ripening fruit. Since its introduction, it is unclear how …

Odor intensity learning in Drosophila
It has been known for a long time that Drosophila can learn to discriminate not only between different odorants but also between different concentrations of the same odor. Olfactory associative learning has been described as a pairing between odorant and electric shock and since then, most of the …

Apoptosis Determinants in Drosophila Melanogaster
The file named "chewsu.pdf" is the primary dissertation file. All other files ("*.mov") are supplemental files and may be viewed individually.

Bcl-2 Function in Drosophila
… pro- and anti-apoptotic Bcl-2 family members. Drosophila encodes two Bcl-2 family members, Debcl (pro-apoptotic) and Buffy (anti-apoptotic). To understand the role of Debcl in Drosophila apoptosis, we produced an authentic null allele at the Debcl locus. Although gross development and lifespans …

Avoidance learning in Drosophila melanogaster
<p>The importance of showing that Drosophila are capable of learning an instrumental response would, with the information already known from genetic studies, enable researchers to possibly isolate the genetic basis of a simple learning process and thus gain greater insight into this phenomenon. If …

Sterol requirements in Drosophila melanogaster
… fluidity and microdomain formation. Drosophila is an excellent model system in which to study functional requirements for membrane sterol because, although it does not synthesize sterol, it nevertheless requires sterols to complete development. Moreover, Drosophila normally …

The Evolution of Drosophila Immunity
… a strong selection force on the evolution of Drosophila immunity. Under the pressure of this natural selection by pathogenic organisms, species diverge along the evolutionary path and depart in phenotypes. Interspecific differences in gene expression are an important contributor to this …

Drosophila TRPA1 controls thermotactic behavior
… in particular, are still poorly understood. Drosophila melanogaster also exhibits strong temperature preferences and robust thermotactic behaviors, although the molecular mechanisms that mediate thermotaxis in Drosophila were unknown. We used a reverse genetic RNA interference (RNAi)-based …

Virulence of Drosophila C virus increased after a host shift and serial passage in Drosophila hosts
… the first two generalities using complex hosts (Drosophila sp) and the highly virulent Drosophila C virus (DCV). The fitness of DCV was utilized as a proxy for virulence (pathogen’s harm to host) and investigated over 10 serial passages of the pathogen. The number of eggs, pupae, and adults were …

Lokalisierung eines Gedächtnisses bei Drosophila melanogaster
… daß das olfaktorische Kurzzeitgedächtnis von Drosophila melanogaster in den Pilzkörpern lokalisiert ist. Zu Beginn dieser Doktorarbeit war bekannt, daß die Pilzkörper notwendig für das Geruchsgedächtnis sind. Drei unabhängige Methoden der Ablation bzw. Veränderung der biochemischen …

Drosophila Model to Study Muscle Atrophy
… genetic factors that can influence MA. </p> <p>Drosophila provides an excellent platform for genetic screening, although it has somewhat limited utility for MA research since insect muscles lack the level of plasticity found in mammalian muscles. We adapted Drosophila flight muscles for a model …

Autophagy in the developing Drosophila brain

The transmission of P elements among species, their spread within species and the strength of selective constraints, as well as the level at which they are imposed on …

Genetic Dissection of DH31 Signaling in Drosophila
… Peptide, is a multifunctional neuropeptide in Drosophila. To evaluate the roles of Dh31 signaling in Drosophila, we took advantage of the KG09001 line because it has a transposable element inserted in the third intron of the Dh31 gene. We employed an excision screen to mobilize the element and …
