Molecular detection, genetic diversity and phylogenetic analysis of anaplasma marginale infecting cattle in South Africa
(University of the Free State, 2015-12)
Bovine anaplasmosis caused by Anaplasma marginale is endemic in South Africa. This
endemicity is due to presence of tick vectors that transmit A. marginale the causal agent

Aspects of geophagia amongst dairy cattle in a feedlot system
(University of the Free State, 2017-03)
English: Modern confinements imposed on animals limit their access to natural resources required for optimal nutrition. This lack of resources may lead to nutrient deficiencies and one of the hypotheses for the deliberate ...

(University of the Free State, 2010-06)
English: The grass leaf miner fly, Agromyza ocularis (Spencer) (Diptera: Agromyzidae) was first described from specimens collected at Ceres (1959), Giant's Castle (1961) and the Maseru (1963) district. These specimens were ...
An ecological analysis of stink bug and lepidopteran borer complexes associated with pecan and citrus orchards in the Vaalharts region
(University of the Free State, 2017-02)
English: This study investigates the insect-plant interactions on citrus fruit and pecan nuts in South Africa. The aims of this study were to determine whether lepidopteran borer pests shuttled between adjacent citrus and ...
Temporal and spatial composition of arboreal insects along the Omaruru River, Namibia
(University of the Free State, 2010-11)
English: Insects play a major role in any ecosystem and are also of extreme importance to the well-being of humans. Amongst others, they are pollinators that indirectly determine food security. On a more negative side, ...

Mating behaviour and competitiveness of male Glossina brevipalpis and Glossina austeni in relation to biological and operational attributes for use in the sterile insect technique
(University of the Free State, 2016)
English:In South Africa, African Animal Trypanosomosis (AAT), caused by Trypanosomae parasites transmitted by Glossina brevipalpis and Glossina austeni (Diptera: Glossinidae), is restricted to the north east of KwaZulu-Natal ...
Foraging behaviour and sensory ecology of the bat-eared fox (Otocyon megalotis)
(University of the Free State, 2016-12)
In the wild, foraging animals face challenges that affect foraging success, including conditions
which influence the usefulness of the sensory input they receive from their environment.
Nocturnal foragers must cope with ...
