Veterinary Entomology

Abstract Research in the field of veterinary entomology is dominated by studies concerning arthropods that affect animal health. In 2019, this research primarily addressed the overwhelming industry need to manage detrimental species such as biting flies and ticks and the ongoing problems caused by insecticide/acaricide resistance evolution in these pests. Research also included evidence supporting the need for the conservation of beneficial species, such as biological control organisms. Many studies in a variety of pest systems have demonstrated the potential detrimental effects of insecticide use on nontarget organisms, and those of veterinary importance are no exception. An emphasis also was placed on research regarding alternative management strategies for veterinary pests. The presentation herein provides a descriptive summary of selected research that contributed greatly to the body of knowledge regarding arthropods of veterinary importance. This included several studies that will pave the way towards more effective veterinary pest management in an effort to improve animal health and welfare and, therefore, the sustainability of animal agriculture.

Lantana camara L. is one of the worst invasive alien species that are categorized worldwide. The objective of this review paper was to review the dispersal and threats posed by Lantana camara L. in Ethiopia and based on review results, to suggest management strategies that can bring solutions to the threats posed by the weed. Both biological characteristics of Lantana camara L. and its dispersal agents have contributed to the success of its dispersal. Even though Lantana camara L. is dispersed in other places within Ethiopia, Debrezeit, Dire Dawa, Harar and Somali are the hotspot areas for the weed. Biodiversity and potential agricultural loss, human and animal health problems and infestation in national parks are the identified threats that Lantana camara L. posed within the country. Utilization of Lantana camara L. for various purposes, prevention of its further dispersal into non-infected areas, use of fire, mechanical and biological control and awareness creation are the suggested management strategies that can bring solutions to the threats posed by the weed within the country.

Antibiotic concentrations vary dramatically in the body and the environment. Hence, understanding the dynamics of resistance evolution along antibiotic concentration gradients is critical for predicting and slowing the emergence and spread of resistance. While it has been shown that increasing the concentration of an antibiotic slows resistance evolution, how adaptation to one antibiotic concentration correlates with fitness at other points along the gradient has not received much attention. Here, we selected populations of Escherichia coli at several points along a concentration gradient for three different antibiotics, asking how rapidly resistance evolved and whether populations became specialized to the antibiotic concentration they were selected on. Populations selected at higher concentrations evolved resistance more slowly but exhibited equal or higher fitness across the whole gradient. Populations selected at lower concentrations evolved resistance rapidly, but overall fitness in the presence of antibiotics was lower. However, these populations readily adapted to higher concentrations upon subsequent selection. Our results indicate that resistance management strategies must account not only for the rates of resistance evolution but also for the fitness of evolved strains.

In spite of ragwort flea beetle (RFB) being present on a Dannevirke dairy farm, pastures were sprayed each winter to reduce ragwort density and limit the risk of ragwort poisoning of stock. The trial on this farm from June 1999 - October 2001, aimed to determine whether herbicide (H) impacted on RFB and how H and RFB each impacted on ragwort growth and persistence. RFBfree areas were created by spraying with insecticide (I). Effects of ragwort on animal health are also reported. High ester 2,4-D (H) boom-sprayed once only, in June 1999, killed most ragwort plants and reduced RFB larvae densities to low levels before the plants died. Once new ragwort established in treatment H, the plants became infested with RFB larvae. RFB larvae were suppressed by I resulting in ragwort density declining more slowly than in treatments where RFB were not suppressed. Insecticide treatments were stopped after 15 months and, at 24 months, ragwort could not be found within the trial area. Ragwort control was attributed to the cessation of herbicide spraying allowing the RFB population to reach a sufficient density to kill both small and large ragwort plants. Sub-clinical ragwort poisoning was found in livers of culled cows that had grazed on ragwort-dense pastures.

#FeesMustFall was a movement whose maxim was, “This revolution will be intersectional, or it will be bullshit.” This article is a self-reflection on my participation as a so-called radical black intersectional feminist in the #FeesMustFall movement at Stellenbosch University. It is also an attempt to provide evidence of the double erasures taking place in the mainstream patriarchal narratives about the #FeesMustFall movement. My story bears witness to the fact that queer black womxn were the backbone of the movement and that #FeesMustFall did indeed occur at Stellenbosch University. These constitute the double erasures taking place in terms of what is and can be known about the #FeesMustFall movement. My reflections serve to make a much-needed contribution to the body of knowledge produced about the #FeesMustFall movement.

Offender Reintegration

Successful social reintegration is critical if we are to reduce recidivism and crime in general. This voice of people article presents a background case for why effective offender reintegration services are key in South Africa, and the Eastern Cape in particular, through an example of the Offender Reintegration programme rendered by the National Institute of Crime Prevention and Reintegration of Offenders (NICRO). Apart from the paucity of literature on offender reintegration, very few voices from people working directly with these former offenders are ever heard. Therefore, this article seeks to address this gap by contributing to the body of knowledge on offender social reintegration.

Objective: To report a case of young male with stroke and bilateral internal carotid artery (ICA) dissection. Background: Cervical Artery Dissection in Stroke Study trial has provided some insight on management of patients with ICA dissection. However, there is a need to modify the management strategies as per specific clinical scenario. Design/Methods: Case report and literature review. Results: A 45-year-old male presented with 1 month old history of acute onset numbness of right half of the body with slurring of speech. Computed tomography angiography showed complete occlusion of left cervical ICA just beyond origin with presence of fusiform dilatation and spiral flap in right extracranial cervical ICA. The patient was started on antiplatelets and taken for endovascular procedure using 2-mesh-based carotid stents. Patient was discharged after 3 days on antiplatelet therapy. At 1-year follow-up, there were no fresh symptoms. Conclusion: This case emphasizes the role of successful endovascular management of carotid dissection in a young male. These clinical situations may not be fully represented in trials, and a case-based approach is required.

The academic literature on consumer engagement and sustainable consumption has developed gradually over the last two decades. The body of knowledge related to the role of food and non-food retailers in this context, however, is only beginning to develop. The purpose of this systematic review is to analyse the existing literature on how retailers fulfil their role in engaging consumers in sustainable consumption. The need for a study with this purpose is proven by the fact that academic literature lacks a systematic review on this topic, despite the ascending trend in the number of published articles in the field. This systematic review is based on a five-step process to ensure quality, replicability, transparency, and reliable conclusions. The reviewed articles were published relatively recently in academic journals from different domains. This review identified seven distinct types of retail marketing interventions (involvement of retailers in marketing actions with the aim to engage consumers in sustainable consumption), 30 types of retail marketing mechanisms (consisting in marketing strategies, techniques, tools, and channels used by retailers), and 14 distinct types of consumer engagement in sustainable consumption patterns. The review suggests an agenda for further research and identifies practical implications for retail management.

Abstract The fourth industrial revolution (4IR) marks the new, advanced era of development in humankind, and globally countries are in the process of ensuring their citizenry’s readiness. In South Africa, various governmental departments, organizations, non-governmental organizations (NGOs) and non-profit organisations (NPOs) are making efforts, through their plans, talks and actions, to attain this status for all her people, particularly women in rural areas. However, the development of women in the rural areas for empowerment remains a concern in developing countries. Consequently, there is a dire need to ensure the developmental status for women in rural areas in the advent of the 4IR, and this paper seeks to demonstrate that information and knowledge may be instrumental in empowering women in rural areas to strive in the 4IR. Accordingly, information and knowledge are a critical resource contributing to the empowerment of women in rural areas for their development. An exploratory question is raised to determine whether South Africa is ready for Fourth Industrial Revolution. The outcome of this paper will contribute to the body of knowledge advocating the importance of information and knowledge in the empowerment of women in rural areas. Significantly, it will generate insights for policymakers on the important role of information and knowledge for women’s development.
