“…Biological control of sweet potato weevil using Beauveria bassiana was found to be as effective as chemical control (Hlerema et al, 2017). Visser (2015) These crop protection R&D products enabled the establishment of supporting tools for the local seed system and they are used by commercial vine growers trained and supported by the ARC.…”

The 2030 Agenda for Sustainable Development Goals (SDG) of the United Nations puts forward a transformational vision to cope with food security, nutrition and health challenges, in which sweetpotato can play an important role. Globally sweetpotato production is valued at US$53.83 billion. The ARC sweetpotato research and development (R&D) program over the past seven decades delivered 31 genetically improved cultivars via demand‐led breeding, managed the collection and maintenance of 375 accessions, contributed towards the optimization of cultivation practices, developed crop protection and diagnostic services, provided stream‐lined seed systems and technology transfer in processing and enterprise development. The ARC's work is part of a large number of interdependent global programs committed to improving livelihoods and nutrition through sweetpotato. This review shares and analyses major achievements, highlights unique research contributions achieved through partnerships and discusses bottlenecks on funding and up‐take of technologies. New research imperatives will involve root phenotyping, employing marker‐based technologies and genome‐wide association studies through new funding received recently. Exploration of the commercialization potential of processed products made from orange‐fleshed sweetpotato will be a major focus of the R&D program. Expansion of partnerships, marketing and financing will be important for future contribution of sweetpotato to the economy.This article is protected by copyright. All rights reserved

Invasion science for society: A decade of contributions from the Centre for Invasion Biology

Biological invasions are a growing problem worldwide. In 2004, the South African Department of Science and Technology, through the National Research Foundation, established a Centre of Excellence for Invasion Biology, with the primary goal of providing scientific understanding and building capacity in the field of biological invasions. South Africa is an extraordinary natural laboratory for the study of biological invasions, and the Centre for Invasion Biology (C·I·B) has capitalised on this situation. During its first decade, the C·I·B generated over 800 publications, and produced almost 200 graduates at honours, master’s and doctoral levels. The C·I·B has therefore made a considerable contribution to building human capacity in the field of biological invasions. Substantial advances have been made in all aspects of invasion science, which is not limited to biology and ecology, but includes history, sociology, economics and management. The knowledge generated by the C·I·B has been used to inform policy and improve management practices at national and local levels. The C·I·B has emerged as a leading institute in the global field of invasion biology, with several unique features that differentiate it from similar research institutes elsewhere. These features include a broad research focus that embraces environmental, social and economic facets, leading to a diverse research programme that has produced many integrated products; an extensive network of researchers with diverse interests, spread over a wide geographical range; and the production of policy- and management-relevant research products arising from the engaged nature of research conducted by the C∙I∙B.

A leaf-mining pest occurring on commercial varieties of Vitis vinifera in South Africa was investigated due to the presence of cocoons on fruit. The leaf miner, Holocacista capensis, was reported on grapevines in 2012. Since its discovery on commercial grape varieties, control strategies have consisted solely of insecticide applications. Despite the fact that the leaf-mining habit is taxonomically diverse and considered ancient, little is generally known of leaf-mining larvae. A review was conducted in order to better understand the leaf-mining strategy and amalgamate the current knowledge of other leaf-mining insects. The general evolutionary history within the full complement of taxa that display the leaf-mining habit is discussed. The review focuses on lepidopteran leaf-mining pests and discloses the known information associated with the first report and the impact of H. capensis in the Western Cape, South Africa. As no control methods have been identified for H. capensis in vineyards, various chemical, biological and cultural control strategies adopted for other leaf-mining pests were investigated. Control options, including the use of entomopathogenic nematodes (EPNs), parasitoids, physical and cultural control measures, were considered and are discussed. Alternate control methods are pertinent for the grape-growing industry to avoid the development of the insecticide resistance that is common amongst leaf miners. This review aims to consolidate the available literature and therefore aid in the development of an integrated pest management strategy to effectively control H. capensis in infested vineyards in South Africa.
