As the Starling Flies
The concept of science evokes forward momentum, a steady march of progress as scientists accumulate knowledge, refine hypotheses, and make theoretical leaps. But science, it turns out, can also meander as much as a wandering bird.

Sex Chromosome Evolution in Blow Flies
… studies observe that the karyotype in blow flies is highly conserved (five pairs of autosomal chromosomes and one pair sex chromosome), there is variation in sex determining mechanisms and sex chromosome structure within closely related species in blow flies. The evolutionary history of sex …

Control of Chironomid Flies Breeding in Sewage Filters
… and control methods of common sewage filter flies has been reviewed with special reference to the chironomid Metriocnemus hyaropetricus (Kieff.) which was the nuisance species breeding on the filters at Tamworth. References have been given for the identification of larval and adult stages of …

Effects of black flies on wild turkey reproductive success
… nest success. Biting insects such as black flies (Diptera: Simuliidae) are a common nuisance often present during the reproductive period of numerous avian species and have the potential to directly (e.g., cause nestling mortality) and indirectly (e.g., increase rate of nest abandonment) …

Hunting tigers and swatting flies : Xi Jinping’s anti-corruption campaign
Why has Xi Jinping, the President of the People’s Republic of China, launched one of the most aggressive anti-corruption campaigns in the history of the country? To answer this question, I constructed a database of over 100 high-level officials who have come under investigation during the campaign. …

An investigation of sugar feeding by black flies (Diptera: Simuliidae)
… on blood-meal acquisition in adult female black flies (Diptera: Simuliidae), the same cannot be said for sugarmeals. Both sexes feed on sugar which provides energy for flight and it has been commonly held that nectar is the major carbohydrate source. This thesis addresses the question of whether …

DNA barcoding of forensically important flies in the Western Cape
… body. As first colonisers, Calliphoridae (blow flies) are often used by forensic entomologists to determine the PMI however, developmental rates of visiting fauna differ substantially which makes correct species identification vital. Traditional methods of identification which assign species …

Characterization and analysis of the flight dynamics of fruit flies
For centuries, the human race has been perplexed by the various complex physical manifestations in nature. Much of what we have seen in nature we have tried to recreate, from the migration tendencies and routes of sea creatures to the flight of birds and insects. The flight of the fly, in …

The evolution of mating systems in black scavenger flies (Diptera: Sepsidae)
Black scavenger flies are characterized by sexual behaviours that are very unusual in insects. I have studied two of the most remarkable elements of their mating systems: the timing of copulations immediately after an oviposition bout (post-oviposition matings) and the males' escorting of …

Entomotoxicological and Thermal Factors Affecting the Development of Forensically Important Flies
… on the development of forensically important flies. In addition different methods of degree-day calculations and development thresholds were used to determine the effects on PMI estimates. The first study determined the effects of ethanol on the development of Phormia regina in vitro. Ground …

Slipping into Sleep: neurodynamics of alertness transitions in humans and fruit flies
The ability to react to events in the external world determines the fate of every living organism, this general state of readiness is called as ’alertness’. What happens to neurodynamics in the brain when alertness fades away as we fall asleep? How is behaviour affected? These questions will help …

THE WISDOM OF THE FLIES. SOCIETY, ENVIRONMENT, AND METABOLIC JUSTICE IN RURAL SARDINIA.
This PhD thesis in Environmental Anthropology explores the mutually reinforcing effects of industrialised food production on humans, nonhumans, and their environments. To do so, it employs the ethnographic data collected over the course of a 12-month fieldwork in Barbagia, rural Sardinia, by living …

From Flies to Mice: Drosophila as a Model System to Study Fat Biology
… gene isolated from naturally occurring obese flies. Through gain- and loss-of-function studies in flies, mammalian cell culture, and mice I showed that the Adipose pathway plays a conserved role in obesity and diabetes. Furthermore, I found that Adipose controls the activity of PPARgamma, a …
