AbstractEntomopathogenic fungi (EPF) are important soil-dwelling entomopathogens, which can be used as biocontrol agents against pest insects. During a survey of the orchard soil at an organic farm, the EPF were identified to species level, using both morphological and molecular techniques. The EPF were trapped from soil samples, taken from an apricot orchard, which were baited in the laboratory, using susceptible host insects. The identification of Metarhizium majus from South African soil, using both morphological and molecular techniques, is verified. The occurrence of M. majus in the South African soil environment had not previously been reported.

Entomopathogenic fungi (EPF) are important soil-dwelling entomopathogens, which can be used as biological control agents against pest insects. EPF are capable of causing lethal epizootics in pest insect populations in agroecosystems. During a survey of the orchard soil at an organic farm, different EPF species were collected and identified to species level, using both morphological and molecular techniques. The EPF were trapped from soil samples taken from an apricot orchard. The traps, which were baited in the laboratory, used susceptible host insects, including the last-instar larvae of Galleria mellonella (wax moth larvae) and Tenebrio molitor (mealworm larvae). The potential pathogenicity of the local Metarhizium majus isolate was tested and verified using susceptible laboratory-reared last-instar T. molitor larvae. The identification of the M. majus isolated from South African soil was verified using both morphological and molecular techniques. The occurrence of M. majus in the South African soil environment had not previously been reported.

Background: This study focuses on the positioning of gender, sexual orientation and people with disabilities in the linguistic landscapes of two selected South African universities, which are located in the Western Cape province.Objectives: This study aims to answer the question: How are power relations depicted through linguistic landscaping in the universities?Methods: Given that there is minimal empirical data in this field, the researcher approached this question by exploring the way in which sexual orientation and people with disabilities are perceived, via the modal resources used in the categorisation of toilet users at the institutions. Specifically, toilet signage was observed as there were only a few other signage or forms of support (such as ramps and lifts – some of which may seem disability-unfriendly in terms of space) and acknowledgement in other places at the institutions for people with disabilities. Data (signs, images, texts, billboards and posters) were collected by means of photography. The interpretive paradigm was used to determine the choice of methodology: critical discourse analysis and multimodality. These were also used to thematically analyse the collected data.Results: Findings revealed that sexuality, as well as subtle inequality, unfortunately remain unravelled areas in South Africa’s higher institutions of learning. In addition, the degenderisation of people with disabilities appears to be prevalent at the institutions, although this may not necessarily be reflective of practices at all higher education institutions in South Africa.Conclusion: Nonetheless, the examined results are stimulating indicators of hegemonic and preferred practices in public places. They also depict the obtainable dissimilar scales and imbalances in society, which are not addressed may impede other authentic and ongoing measures of social integration and advancement.

This chapter examines the complex relationship between diaspora and citizenship. Mohandas Karamchand Gandhi famously developed his tactic of satyagraha on South African soil, cementing a deep relationship with India. Against this background, this chapter examines new diasporic connections between Indian South Africans and India, buoyed by the Indian government’s introduction of a number of measures such as a new ministry, an annual official diaspora convention in India, and the offer of special status for members of the Indian diaspora, but fell short of granting dual citizenship, arguably over concerns about security. This chapter provides a detailed examination of the visit of Prime Minister Narendra Modi to South Africa in 2016. This politically and strategically important visit of 2016 generated intense debates over the relationship between India and its diaspora, India and South Africa, Indians and Africans, and Hindus and Muslims.

The South African genus Griffiniana Karny of squamipterous to macropterous katydids (Tettigoniidae: Mecopodinae:Aprosphylini) is revised and a key to species is provided; G. duplessisae sp. n. from the Western Cape Province is de-scribed; acoustic behavior of G. capensis Karny, G. duplessisae, and G. longipes (Naskrecki) is described. The genusEwanella Naskrecki is considered a junior synonym of Griffiniana, and E. breviuscula Gorochov is synonymized with G. longipes.
