Abstract:

[Abstract]: The development and commercial release of midge resistant grain sorghum hybrids in Australia has been one of the real success stories of the sorghum industry. Almost all the current commercial sorghum hybrids grown contain a significant baseline of midge resistance that has greatly reduced that pest status of this insect. However while breeding efforts have been successful, it seems only one mechanism of resistance remains present in commercial hybrids. This mechanism of resistance known as ‘ovipositional-antixenosis’ is polygenic in nature and has contributed to the gradual reduct

Abstract:

Three exclusive studies (in-vitro, observational and empirical) comprise this doctorate dissertation aimed at assessing the capacity of midges (Order Diptera: Families Chironomidae, Chaoboridae and Ceratopogonidae) as paleoecological indicators. In-vitro experiments were conducted to determine the impact that temperature and salinity have on midge development and survival. Results indicate that some taxa may achieve optimal development at cooler temperatures; most taxa are cued for emergence by, and require, warmer temperatures; exposure to temperatures that are too warm may result in develo

Abstract:

Arthropod-borne viruses (arboviruses) cause diseases of significant consequence to human and animal health. The aspect of the lifecycle that distinguishes an arbovirus from another viral group, is the requirement for replication in an arthropod vector and vertebrate host. Culicoides midges (order: Diptera; family: Ceratopogonidae) transmit several arboviral diseases of economic importance including bluetongue virus (BTV), a double-stranded RNA virus within the genus Orbivirus (family: Reoviridae). The ability of an arbovirus, such as BTV, to replicate, disseminate and be transmitted to a susce

Abstract:

The potential restriction to effective dispersal and gene flow caused by habitat fragmentation can apply to multiple levels of evolutionary scale; from the fragmentation of ancient supercontinents driving diversification and speciation on disjunct landmasses, to the isolation of proximate populations as a result of their inability to cross intervening unsuitable habitat. Investigating the role of habitat fragmentation in driving diversity within and among taxa can thus include inferences of phylogenetic relationships among taxa, assessments of intraspecific phylogeographic structure and analys

The mechanisms controlling the transmission of bluetongue virus (DTV) by vector Culicoides species were studied using immunohistochemistry, virus titration assays, in vitro transmission tests, viral binding protein analyses and transmission electron microscopy.

However only 35.4% of midges were . persistently infected after ingestion of an infectious blood meal, while only 12.1 % of pers

Abstract Culicoides biting midges (Diptera: Ceratopogonidae) are responsible for the transmission of a large number of pathogens to livestock and wild animals. In this study the presence of the genus, using light traps based at four different sites within the National Zoological Gardens of South Africa, was investigated during 2002-2004. In total, 37species were recorded, including large numbers of Culicoides irnicola Kieffer, 1913, which is responsible for the transmission of economically important arboviruses in South Africa, Europe, Middle and Far East.

Abstract:

South Africa is known for its highly endemic and remarkably species-rich fauna and flora. The Greater Cape Floristic Region, consisting of the Cape Floristic Region and the Succulent Karoo Region, is home to South Africa's second most diverse plant family, the Aizoaceae. While the Aizoaceae are relatively well studied, there has been little work done on their associated insect fauna. Preliminary observations in recent years revealed a diverse community of gall midges on these plants. This study aimed to investigate the gall midges associated with two speciose genera of Aizoaceae and it is the
