Thermal tolerance in a south-east African population of the tsetse fly Glossina pallidipes (Diptera, Glossinidae) : implications for forecasting climate change impacts

Terblanche, John S.; Clusella-Trullas, Susana; Deere, Jacques A.; Chown, Steven L. (2008-01)

For tsetse (Glossina spp.), the vectors of human and animal trypanosomiases, the physiological mechanisms linking variation in population dynamics with changing weather conditions have not been well established. Here, we ...

Evolutionary responses of discontinuous gas exchange in insects

White, Craig R.; Blackburn, Tim M.; Terblanche, John S.; Marais, Elrike; Gibernau, Marc; Chown, Steven L. (National Academy of Sciences, 2007-05)

The discontinuous gas-exchange cycles (DGCs) observed in many quiescent insects have been a cause of debate for decades, but no consensus on their evolutionary origin or adaptive significance has been achieved. Nevertheless, ...

Critical thermal limits depend on methodological context

Terblanche, John S.; Deere, Jacques A.; Clusella-Trullas, Susana; Janion, Charlene; Chown, Steven L. (Royal Society of Publishing, 2007)

A full-factorial study of the effects of rates of temperature change and start temperatures was undertaken for both upper and lower critical thermal limits (CTLs) using the tsetse fly, Glossina pallidipes. Results show ...

Thermal limits of wild and laboratory strains of two African malaria vector species, Anopheles arabiensis and Anopheles funestus

Lyons, Candice L.; Coetzee, Maureen; Terblanche, John S.; Chown, Steven L. (BioMed Central, 2012-07)

Abstract Background Malaria affects large parts of the developing world and is responsible for almost 800,000 deaths annually. As climates change, concerns have arisen as to how this vector-borne disease will be ...

Desiccation tolerance as a function of age, sex, humidity and temperature in adults of the African malaria vectors Anopheles arabiensis and Anopheles funestus

Lyons, Candice L.; Coetzee, Maureen; Terblanche, John S.; Chown, Steven L. (The Company of Biologists, 2014-09)

Adult mosquito survival is strongly temperature and moisture dependent. Few studies have investigated the interacting effects of these variables on adult survival and how this differs among the sexes and with age, despite ...
