Abstract:

Several communities in developing countries derive substantial part of their livelihood needs from alien plants cultivated and managed in home gardens. The aim of this study was to assess useful alien plant species cultivated and managed in home gardens of Limpopo province in South Africa. Semistructured interviews, personal observation, and guided walks with 300 participants between January 2015 and December 2016 were employed to obtain data on names of alien plants cultivated in home gardens and their use categories. A total of 101 plant species belonging to 44 families were recorded from the study area. More than half of the species (66.3%) belonged to 14 families, Fabaceae, Asteraceae, Rosaceae, Solanaceae, Lamiaceae, Anacardiaceae, Poaceae, Amaranthaceae, Apocynaceae, Brassicaceae, Cactaceae, Euphorbiaceae, Moraceae, and Myrtaceae. Twenty-six use categories of alien plants were identified in this study with the majority of species (75.2%) used for medicinal purposes, followed by ornamental (33.7%), edible fruits (24.8%), spices (16.8%), vegetables (16.8%), shade (11.9%), beverages (10.9%), construction materials (8.9%), firewood (7.9%), and hedge (7.9%). These findings corroborate the existing body of knowledge emphasizing the importance of plants grown and managed in home gardens to the livelihood needs of local communities.

Abstract:

First and additional host-plant records for 38 species of Gelechiidae from South Africa and Kenya are presented. An annotated list with brief descriptions of larval biology and known geographical distributions is presented. Three species are described as new: Mesophleps kruegeri sp. nov. (Namibia: Kavango Region and South Africa: Limpopo Province), Istrianis inquilinus sp. nov. (South Africa: North West Province), and Teleiopsis sharporum sp. nov. (South Africa: Limpopo Province). The new combination Istrianis epacria (Bradley, 1965) comb. nov. is proposed. The male genitalia of Hypatima melanecta (Meyrick, 1914) is described for the first time. It is noticed that male hitherto associated with T. commaculata (Meyrick, 1918) in fact refers to T. pundamilia Bidzilya & Mey, 2018. Hypatima stasimodes (Meyrick, 1931), Dichomeris coenulenta (Meyrick, 1927), Dichomeris eustacta Meyrick, 1921, Neotelphusa similella Janse, 1958 and Argophara epaxia Janse, 1963 are recorded for the first time from South Africa, and Istrianis epacria is new for Kenya. The adults, male and female genitalia are illustrated for some species mentioned in paper. The first record of the genus Teleiopsis Sattler, 1960 from South Africa is briefly discussed.

Abstract:

Rising demand for medicinal plants has led to increased pressure on wild plant populations. This, combined with shrinking habitats, means that many species in South Africa are now facing local extinction. In 1997, a study was initiated to determine the extent of trade in medicinal plants in the South African Lowveld (the low lying plains to the east of the Drakensberg escarpment), and to investigate socio-economic factors influencing trade and resource management. Trade was not as extensive in the Lowveld as in major urban markets such as Durban or the Witwatersrand (Johannesburg and surrounding towns), either in terms of the quantity, number or range of species sold, or the numbers of people relying on the trade for an income. In markets assessed in Mpumalanga Province, 176 species were identified (71% of the vernacular names encountered in the market place), representing 69 plant families. In Limpopo, 70 different species were identified (84% of the vernacular names encountered in the market place), representing 40 families. Imports were significant in Mpumalanga (33% of the plants on offer), mainly from Mozambique. A detrended correspondence analysis showed substantial differences between species traded in Mpumalanga and those sold in Limpopo. There was little variation in the species stocked by vendors in Mpumalanga, regardless of the season, the attributes of the seller, or whether business was carried out in urban or rural areas. In contrast, there was considerable variation in the stock inventories of the Limpopo traders. Despite the lower levels of local trade, increased harvesting pressure is being experienced regionally, to meet demand in metropolitan centres such as the Witwatersrand. This study showed considerable local variation and complexities in the harvesting and marketing of medicinal plants, with both a national and an international dimension. This dual spatial scale presents both opportunities and challenges in the management of these plants, which need to be addressed simultaneously, particularly with respect to research requirements and development of predictive models and capacity. Cooperation in conservation strategies and policies is required at regional, national and international levels, while ensuring that management initiatives take into account local market conditions and the socio-economic realities facing both consumers and those who depend on the trade for their livelihoods.

Abstract:

Trading of herbal medicines generates economic opportunities for vulnerable groups living in periurban, rural, and marginalized areas. This study was aimed at identifying medicinal plant species traded in the Limpopo province in South Africa, including traded plant parts, conservation statutes of the species, and harvesting methods used to collect the species. Semistructured questionnaire supplemented by field observation was used to collect data from owners of 35 informal herbal medicine markets in the Limpopo province. A total of 150 medicinal plant products representing at least 79 plant species belonging to 45 botanical families, mainly the Fabaceae (11.4%), Asteraceae (7.6%), and Hyacinthaceae (6.3%), were traded in the study area. Roots (50.0%), bulbs (19.0%), and bark (16.0%) were the most frequently sold plant parts. Some of the traded species which includeAlepidea amatymbica, Bowiea volubilis, Brackenridgea zanguebarica, Clivia caulescens,Dioscorea sylvatica,Elaeodendron transvaalense, Encephalartos woodii,Eucomis pallidiflorasubsp.pole-evansii,Merwilla plumbea,Mondia whitei,Prunus africana, Siphonochilus aethiopicus, Synaptolepis oliveriana,andWarburgia salutarisare of conservation concern and listed on the South African Red Data List.Findings of this study call for effective law enforcement to curb illegal removal of wild plants especially those species that are at the verge of extinction.

Source, harvesting, conservation status, threats and management of indigenous plant used for respiratory infections and related symptoms in the Limpopo Province, South Africa. Biodiversitas 20: 789-810. This survey explored Bapedi traditional healer’s (THs) practices pertinent to native plants used to treat respiratory infections (RIs) and related symptoms (RSs). Semi-structured questionnaires and participatory observations were used to gather information from 240 THs in the Limpopo Province, South Africa. 186 plants from 75 families were harvested by these THs, mainly from the communal lands (81.2%), throughout the year. Plant parts used for RIs and RSs remedies was destructively harvested in wilderness compared to homegardens. Most (n=174) species from which these parts are obtained appears on the South African National Red Data List of plants, with 88.5% having a list concern status. This included Adansonia digitata, Boscia albitrunca, Catha edulis, Securidaca longepedunculata and Sclerocarya birrea which are also protected under the National Forest Act of 1998 (Act no. 84 of 1998). A further, 8.6% (n=15) of Red Data Listed plants are of conservation concern, with various status namely near threatened (38.3%), declining (20%), data deficient (13.3%), critically endangered and vulnerable (3.3%, for each), as well as endangered (6.6%). There were both consensus and disjunction amongst THs and Red Data List regarding the status of plants in the wild. This study provides valuable data for the conservation of medicinal plants in Limpopo Province.

Abstract:

Plants used for making birdlime and indigenous knowledge associated with the practice in Soutpansberg region, Vhembe Biosphere Reserve, Limpopo province, South Africa have been documented. Twelve birdlime-making plant species belonging to Apocynaceae, Celastraceae, Euphorbiaceae, Loranthaceae, Moraceae and Sapotaceae families were recorded. The common species included Maytenus peduncularis (Sond.) Loyes cited by 23.6% informants, Euphorbia pulvinata Marloth (17.2%) and Landolphia kirkii Dyer (12%). Plant parts used were latex (50%), fruit (34%), root (8) and the mixture of latex and fruit (8%). Documentation of plant species used for birdlime-making is of great interest, not only for preservation of the Vhavenḓa's traditional culture, but also for promoting economic subsistence, nutritional value and livelihood amongst poor and marginalized people.

Abstract:

To the best of our knowledge there are presently no ethnobotanical surveys focusing on the utilisation of herbal remedies for asthma in South Africa. The present study is therefore an attempt to fill this gap in knowledge. A total of 140 Bapedi traditional healers (THs) practicing in the Capricorn, Sekhukhune, and Waterberg districts of the Limpopo Province (South Africa) were queried using semistructured questionnaires, supplemented by field observations during face-to-face interview. A total of 104 medicinal plant species (92 indigenous and 12 exotics) belonging to 92 genera, distributed across 54 botanical families, mostly the Asteraceae and Fabaceae (18.5%, for each) as well as Malvaceae (12.9%), were used as antiasthmatics and related symptoms by these THs. Most of the plants were trees and herbs (37.5%, for each), with root (57%), leaf (15.8%), and bark (7.5%), respectively, being the saliently used parts for preparation of remedies.Clerodendrum ternatum,Cryptocarya transvaalensis,Lasiosiphon caffer,Enicostema axillare,Mimusops obovata,Sclerocarya birrea, andStylochaeton natalensiswere widely used and valued by all THs across the surveyed districts. Furthermore, these taxa also scored both the highest use value and fidelity level indexes as asthma therapies. Overall, the larger number of species documented in the present study is recorded for the first time in literature as asthma and/or related symptoms remedies. Our study finding generally contributes towards an establishment of South African database of herbal therapies used traditionally against these conditions.

Abstract:

The aim of the study was to scientifically evaluate the antimycobacterial activity of selected indigenous medicinal plants from the Limpopo Province used for the treatment of humans with symptoms ofMycobacterium tuberculosis. The leaves of five plant species (Apodytes dimidiata, Artemisia, Combretum hereroense, Lippia javanica, and Zanthoxylum capense) were collected from the Lowveld National Botanical Garden in Nelspruit, South Africa. The dried leaves were powdered and extracted using hexane, dichloromethane, acetone, and methanol. Antimycobacterial activity was evaluated using microdilution assay and bioautography andρ-iodonitrotetrazolium violet (INT) as indicator. Antioxidant activities were determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH). Phytochemical content of extracts was further evaluated. The acetone extracts ofL. javanicadisplayed antioxidant activity on BEA chromatogram. T Acetone extracts ofA. afrahad MIC value of 0.39 mg/mL againstMycobacterium smegmatisATCC 1441. Acetone extracts ofC. hereroenseandL. javanicahad MIC value of 0.47 mg/mL. Four bands that inhibited the growth ofM. smegmatiswere observed atRfvalues of 0.12, 0.63, and 0.87 on BEA and 0.73 on EMW. The plant speciesA. dimidiata, A. afra, C. hereroense,andL. javanicain this study demonstrated their potential as sources of anti-TB drug leads.

Abstract:

Pepino mosaic virus (PepMV) (genus Potexvirus) is a highly infectious virus that is responsible for significant losses in yield of tomato fruit (Solanum lycopersicum) across Europe, Asia, and the Americas in the last decade (1). During the winter growing season of 2008, uneven discoloration of tomato fruit from farms in Limpopo Province, South Africa, was detected at the Pretoria fresh produce market. Twenty fruit were randomly selected from five different suppliers in this region and the 100 samples were batched into subsamples of five fruit. Leaves with suspect mosaic and bubbling symptoms were also detected from farms in Limpopo and were thus sampled. Leaf and fruit samples were tested by double antibody-sandwich (DAS)-ELISA (2) using polyclonal antibodies against PepMV (Agdia, Elkhart, IN) combined with appropriate positive and negative controls. Fruit samples from two of the suppliers, and all leaf samples tested, reacted strongly with PepMV antibodies. Inoculum was prepared from pooled DAS-ELISA-positive leaf samples and inoculated onto 10, 4-week-old, susceptible S. lycopersicum cv. Rooikhaki seedlings. After 3 weeks, all inoculated plants had developed characteristic PepMV symptoms (2) including leaf bubbling, distortion, and curled leaves. Older leaves developed yellow spots and light/dark green leaf mosaic while apical regions were stunted and branches were distorted to form ‘nettle-head’ symptoms. Fruit surfaces were marbled or displayed flaming and uneven discoloration. Leaves from symptomatic plants were sampled for confirmation of PepMV infection by DAS-ELISA and all samples reacted positively with PepMV antibodies. Total RNA was extracted from 500-μg replicates of pooled leaf samples from infected plants with the RNeasy Plant Mini Kit (Qiagen, Hilden, Germany), and amplified by conventional two-step reverse-transcription-PCR using a PepMV-specific primer set: Ker 1 (2) and PepCP-R (4) for a 986-bp region, including the coat protein, of the PepMV genome. PCR products were cloned into pTZ57R/T vector (Fermentas, Vilnius, Lithuania [UAB]) and six clones were purified and sequenced using universal M13 primers (3). Phylogenetic analysis clustered the sequence with EU (European), LP (Peruvian), US1 (United States)/CH1 (Chilean) and US2/CH2 PepMV isolates. The PepMV isolate accessions for US2/CH2 (AY509927, FJ612601, EF408821, FJ212288, and DQ000985) were identified as the closest relatives based on 98 to 99% nucleotide similarity obtained using BLASTN. The coat protein sequence of the South African isolate was submitted to GenBank (Accession No. HQ872607). To our knowledge, this is the first confirmed report of PepMV in South Africa. Further studies are necessary to determine its incidence and spread in this country. The presence of PepMV signals the urgent need for adoption of appropriate phytosanitary measures to restrict the spread and impact of this virus. References: (1) I. M. Hanssen and B. P. H. J. Thomma.

Abstract:

AbstractWonderkrater, a Middle Stone Age site in the interior of South Africa, is a spring and peat mound featuring both paleoclimatic and archaeological records. The site preserves three small MSA lithic assemblages with age estimates of 30 ka, >45 ka and 138.01±7.7 ka. Here we present results of the pollen analysis of a core retrieved from the middle of the peat mound, which covers, with hiatuses, the timespan between ca. 70±10 ka and 30 ka. Pollen percentages of terrestrial, local aquatic, and semi-aquatic plants reveal changes in the regional climate and in the water table of the spring. Results identify regional wet conditions at ca. 70±10 ka, followed by a dry and a wet period between 60 ka and 30 ka. Superimposed on these three phases, recurring changes in the size and depth of the water table are observed between >45 ka and 30 ka. Wet conditions at 70 ka and 30 ka are tentatively correlated here with Marine Isotope Stage 4 and Heinrich Stadial 3, respectively. A warm and dry savanna landscape was present during human occupation older than 45 ka, and a wet phase was contemporaneous with the final occupation, dated at ~30 ka.

Abstract:

The South African mining industry is one of the largest producers of platinum (Pt) in the world. Workers in this industry are exposed to significant amounts of dust, and this dust consists of particles sizes that can penetrate deep inside the respiratory region. A cross-sectional study was conducted to evaluate dust exposure risk at two Pt mine waste rock crusher plants (Facility A and B) in Limpopo, South Africa. Workers’ demographic and occupational information was collected through a structured questionnaire, a walk-through observation on facilities’ processes, and static dust sampling for the collection of inhalable and respirable dust particles using the National Institute for Occupational Safety and Health (NIOH) 7602 and the Methods for Determination of Hazardous Substance (MDHS) 14/4 as guidelines. Only 79% of Pt mine workers, used their respiratory protective equipment (RPE), sixty-five percent were exposed to work shifts exceeding the recommended eight hours and 8.8% had been employed for more than ten years. The mean time-weighted average (TWA) dust concentrations between Facility A and B showed a significant difference (p < 0.026). The Pt mine’s inhalable concentrations (range 0.03–2.2 mg/m3) were higher than the respirable concentrations (range 0.02–0.7 mg/m3), however were all below the respective international and local occupational exposure limits (OELs). The Pt mine’s respirable crystalline silica (SiO2) quartz levels were all found below the detectable limit (<0.01 mg/m3). The Pt miners had increased health risks due to accumulated low levels of dust exposure and lack of usage of RPE. It is recommended that an improved dust control program be put in place which includes, but is not limited to, stockpile enclosures, tire stops with water sprays, and education on the importance of RPE usage.

Abstract:

There is very little scientific information on indigenous plants used for medicinal purposes. Therefore, the aim of the study was to evaluate the antibacterial and antioxidant activities of the leaves of Commelina africana, Elephantorrhiza elephantina, Dombeya rotundifolia, and the whole plant excluding the roots of Schkuhria pinnata indigenous medicinal plants from the Limpopo Province, which may be used for the treatment in humans infected with bacterial pathogens. The screening of different phytoconstituents using standard methods revealed the presence of terpenoids, flavonoids, tannins, and saponins. The total phenolic, tannin, and flavonoid content were estimated using spectrophotometric methods. D rotundifolia had the highest amounts of phenol (259.00 ± 2.65 mg of gallic acid equivalent [GAE]/g), tannin (330.33 ± 15.63 mg of GAE/g), and flavonoid (19.90 ± 0.75 mg of quercetin equivalent [QE]/g) content, while S pinnata had the least. All the plants had antibacterial activity against Escherichia coli and Pseudomonas aeruginosa with the bioautography method. The microbroth dilution assay revealed antibacterial activity with minimum inhibitory concentration values raining from 0.02 to 2.50 mg/mL. D rotundifolia had the highest antioxidant activity in both the free radical scavenging and ferric reducing power methods. S pinnata and C africana extracts had high antibacterial activity, while D rotundifolia had high antioxidant activity, which made them potential plants for isolation of bioactive compounds and possible application in the pharmaceutical industry.

Abstract:

Abstract Background Community health workers (CHWs) are an essential cadre in the health systems of many low- and middle-income countries. These workers provide a wide variety of services and are key to ongoing processes of task shifting within human immunodeficiency virus programmes in particular. Ward-based outreach teams (WBOTs) are South Africa’s latest iteration of the CHW programme and have been introduced as part of the National Department of Health’s Primary Health Care Re-engineering programme. Methods In order to assess the perceived effectiveness of the WBOTs in supporting the ongoing rollout of antiretroviral therapy, tuberculosis care and patient support, we conducted a qualitative investigation focusing on the perceived successes and challenges of the programme among CHWs, community leaders, healthcare workers and community members in the Mopani district, Limpopo province, South Africa. Results The CHW programme operates across these contexts, each associated with its own set of challenges and opportunities. Conclusions While these challenges may be interrelated, a contextual analysis provides a useful means of understanding the programme’s implementation as part of ongoing decision-making processes.

Abstract:

Seasonal climate outlooks provide one tool to help decision-makers allocate resources in anticipation of poor, fair or good seasons. The aim of the ‘Climate Outlooks and Agent-Based Simulation of Adaptation in South Africa’ project has been to investigate whether individuals, who adapt gradually to annual climate variability, are better equipped to respond to longer-term climate variability and change in a sustainable manner. Seasonal climate outlooks provide information on expected annual rainfall and thus can be used to adjust seasonal agricultural strategies to respond to expected climate conditions. A case study of smallholder farmers in a village in Vhembe district, Limpopo Province, South Africa has been used to examine how such climate outlooks might influence agricultural strategies and how this climate information can be improved to be more useful to farmers. Empirical field data has been collected using surveys, participatory approaches and computer-based knowledge elicitation tools to investigate the drivers of decision-making with a focus on the role of climate, market and livelihood needs. This data is used in an agent-based social simulation which incorporates household agents with varying adaptation options which result in differing impacts on crop yields and thus food security, as a result of using or ignoring the seasonal outlook. Key variables are the skill of the forecast, the social communication of the forecast and the range of available household and community-based risk coping strategies. This research provides a novel approach for exploring adaptation within the context of climate change.

Abstract:

Smallholder livestock farmers who depend on natural communal grazing lands are particularly vulnerable to climate change as well as to food insecurity and should be encouraged to grow drought-tolerant fodder crops. Moringa oleifera is a highly valued plant, due to its exceptionally high nutritional content. This study was conducted at two experimental sites in the Limpopo province of northern South Africa to evaluate for the first time the effect of plant density and cutting interval on biomass production and chemical composition of moringa grown under two diverse climatic conditions. Four different planting densities (435,000, 300,000, 200,000, and 100,000 plants/ha) were arranged in a randomized complete block design and experimental samples were replicated four times. Data for biomass and gravimetric soil moisture content were collected each time the plants reached a height of 50 cm. Harvested leaves were analysed for chemical composition. An increase in the plant density led to elevated biomass production at both study locations, ranging between 527 and 2867 kg/ha. Moringa is capable of meeting all nutrient requirements of livestock depending on harvest time and location.

Abstract:

AbstractIn our ongoing research on edible insects in the Limpopo Province of South Africa, we have found evidence of the unsustainable harvesting of edible insects and the food plants of certain insects. The decline in the edible insect industry, together with the need for food security provides a strong incentive to investigate possible causes of problems using different knowledge systems. Any solution to these problems needs to take Indigenous Knowledge Systems (IKS) into account if it hopes to be successful and sustainable. We have found that different communities have different explanations for the same phenomena. Some of these explanations correspond with the explanations for the same phenomena in Western science. Where areas of overlap between IKS and Western science exist, these can be used in education in such a way that recommendations for sustainable harvesting can be developed with reference to African science. In this process, the area of overlap between the systems may grow as information from one system is incorporated in another. In this contribution the overlapping roles of IKS, African science and Western science are explored in the teaching of the sustainable harvesting of Indigenous resources for food security and conservation. This creates opportunities to teach relevant science in such a way that the concerned communities can benefit through better food security and the conservation of culturally important plants and animals.

Abstract:

The aim of the study was to evaluate the biological activities and safety of commercial herbal concoctions manufactured in Ga Maja (Limpopo province). Microbial contamination was evaluated by spread-plating the concoctions on agar plates. The VITEK 2 instrument was used for identification of the pure cultures. Nutritional content of the concoctions was determined. Thin layer chromatography was used to analyze the chemical constituents of the extracts. The microdilution assay and bioautography were used to evaluate antimicrobial activity against selected microorganisms. Sodium, potassium, and zinc were elements most abundant in the concoctions. Phytochemical screening revealed the presence of various phytoconstituents. Acetone extracts of Hypoxis hemerocallidea and Kirkia wilmsii extracts had antioxidant activity. The minimum inhibitory concentrations values against test bacteria ranged between 0.02 and 0.63 mg/mL. Further studies are required to isolate bioactive compounds and evaluate their cytotoxicity. Caution in the consumption of the herbal mixtures should be adhered to.

Abstract:

In December 2006, symptoms typical of iris yellow spot caused by Iris yellow spot virus (IYSV; genus Tospovirus, family Bunyaviridae) were observed on scapes (seed stalks) in an onion (Allium cepa L.) seed crop in the Klein Karoo of the Western Cape Province, South Africa. Symptoms included diamond-shaped chlorotic or necrotic lesions on the scapes, some of which had ‘green-islands’ with nested diamond-shaped lesions, as well as indistinct, circular to irregular, chlorotic or necrotic lesions of various sizes. At the time symptoms were observed, approximately 5% of the scapes had lodged as a result of extensive lesions resembling those caused by IYSV. The crop was 2 to 3 weeks from harvest. Symptomatic tissue from two plants (two samples from one plant and four samples from the other plant) was tested for IYSV by reverse-transcriptase (RT)-PCR. Total RNA was extracted from symptomatic scape tissue with the SV Total RNA Isolation System (Promega, Madison, WI) according to the manufacturer's instructions. First strand cDNA was synthesized with the RevertAid H Minus First Strand cDNA Synthesis kit (Fermentas Inc., Hanover, MD), followed by PCR amplification with primers IYSV-For (TGG YGG AGA TGY RGA TGT GGT) and IYSV-Rev (ATT YTT GGG TTT AGA AGA CTC ACC), which amplify the nucleocapsid (NP) gene of IYSV. An amplicon of expected size (approximately 750 bp) was observed for each of the symptomatic plants assayed and was sequenced. Comparison of the sequence (GenBank Accession No. EF579801) with GenBank sequences revealed 95% sequence identity with the NP gene of IYSV GenBank Accession No. EF419888, with eight amino acid differences. The known geographic distribution of IYSV in onion bulb or seed crops has increased rapidly in recent years in many areas of the world (1). To our knowledge, this is the first confirmation of IYSV in South Africa. Approximately 6,100 ha of onion bulb crops are grown annually in South Africa in the Western Cape, Kwazulu Natal, Limpopo, and Northern Cape provinces, and 600 ha of onion seed crops are grown primarily in the semi-arid regions of the Western Cape. Examination of an additional 10 onion seed crops in the Klein Karoo during January 2007 revealed the presence of iris yellow spot in three more crops at approximately 5% incidence in each crop. The four symptomatic crops had all been planted as bulb-to-seed crops, using vernalized bulbs produced on the same farm. This suggests that IYSV may have been disseminated into the seed crops on the vernalized bulbs, either as infected bulb tissue or in viruliferous thrips on the bulbs. Reference: (1) D. H. Gent et al.
