A Study on the Use of New Media in Museums to Forge the Consciousness of Chinese National Community: A Case Study of Museums in Guangxi Zhuang Autonomous Region

In the era of "Internet +," the vigorous development of digital media technology has provided a new way and a new method for forging a sense of community in the Chinese nation. As an important cultural position, museums should conform to the trend of The Times, give full play to the advantages of new media communication, and play an active role in education and publicity. This paper takes the Museum of Guangxi Zhuang Autonomous Region (hereinafter referred to as Guangxi Museum) as an example, sorts out the application of short videos in Guangxi Museum, and puts forward the path for Guangxi Museum to use short videos to spread awareness of the community of the Chinese nation. The first is to refine the short video theme in-depth exploration of different cultural themes. Second, we should optimize the short video content, pay attention to the innovation of form and content, and give play to the advantages of interactivity and fun. Third, it is necessary to enrich the presentation of short videos and use the platforms of major institutions to allow the public to experience the charm of culture without leaving home. Fourth, it is necessary to expand the transmission channels of short videos and use the combination of online and offline methods to display cultural content in a three-dimensional manner. Guangxi Museum integrates the consciousness of building the Chinese national community into the whole process of organizing the exhibition, and it empowers Guangxi Museum through short videos to strive for a better communication effect.

Factors of Positive Leadership Affecting Optimistic Attitude toward Self-Efficacy in Clinic Staff in Universities

Nursing department workers are the largest group in a school clinic. They are also the most important of the human resources. The emotional burden of witnessing the stages of life is accompanied by the heavy work that creates an extremely high level of pressure. This is also an obstacle to a good doctor-patient relationship. Therefore, it emerges as an important research topic that can help to improve the situation as well as promote psychological health and self-efficacy of the school clinic staff. In order to fill in this research gap, school clinic staff of universities in Guangxi Zhuang autonomous region were selected as the research participants. A total of 450 copies of the questionnaire were distributed to the potential respondents. After removing the invalid and incomplete ones, 364 valid copies were retrieved, with a retrieval rate of 81%. The collected data were tested using Amos to understand the relationships among positive leadership, optimistic attitude, and self-efficacy. As a result of the analyses, it was found out that when they have a positive attitude, leaders of the clinic staff in universities can improve the attachment and self-confidence of the school clinic staff. This encourages them to have a higher level of willingness to contribute to the development of the institution. Another finding of the study was that a university leader should adopt a hands-on, positive paradigm to enable continuous development and create a positive working environment. Finally, it was found out that if a university leader builds a positive energy network, he can improve the coherence among the staff and encourage them to be willing to contribute by modelling other workers. According to the results, it is expected that this study will help clinic staff to generate optimistic attitude which promotes self-efficacy.

Spatial analysis of the impact of urban built environment on cardiovascular diseases: a case study in Xixiangtang, China

BackgroundThe built environment, as a critical factor influencing residents' cardiovascular health, has a significant potential impact on the incidence of cardiovascular diseases (CVDs).MethodsTaking Xixiangtang District in Nanning City, Guangxi Zhuang Autonomous Region of China as a case study, we utilized the geographic location information of CVD patients, detailed road network data, and urban points of interest (POI) data. Kernel density estimation (KDE) and spatial autocorrelation analysis were specifically employed to identify the spatial distribution patterns, spatial clustering, and spatial correlations of built environment elements and diseases. The GeoDetector method (GDM) was used to assess the impact of environmental factors on diseases, and geographically weighted regression (GWR) analysis was adopted to reveal the spatial heterogeneity effect of environmental factors on CVD risk.ResultsThe results indicate that the built environment elements and CVDs samples exhibit significant clustering characteristics in their spatial distribution, with a positive correlation between the distribution density of environmental elements and the incidence of CVDs (Moran’s I > 0, p < 0.01). Further factor detection revealed that the distribution of healthcare facilities had the most significant impact on CVDs (q = 0.532, p < 0.01), followed by shopping and consumption (q = 0.493, p < 0.01), dining (q = 0.433, p < 0.01), and transportation facilities (q = 0.423, p < 0.01), while the impact of parks and squares (q = 0.174, p < 0.01) and road networks (q = 0.159, p < 0.01) was relatively smaller. Additionally, the interaction between different built environment elements exhibited a bi-factor enhancement effect on CVDs. In the local analysis, the spatial heterogeneity of different built environment elements on CVDs further revealed the regional differences and complexities.ConclusionsThe spatial distribution of built environment elements is significantly correlated with CVDs to varying degrees and impacts differently across regions, underscoring the importance of the built environment on cardiovascular health. When planning and improving urban environments, elements and areas that have a more significant impact on CVDs should be given priority consideration.

Forest above-ground biomass estimation based on strongly collinear variables derived from airborne laser scanning data

Airborne laser scanning technique (ALS) is the most appealing remote sensing technique for the precise estimation of forest above-ground biomass (AGB). Significantly strong correlations (collinearity) among the independent variables derived from ALS data decrease the accuracy of developed AGB models. To address this issue, we propose a novel variable selection algorithm-an improved sure independence screening (SPV), which integrates the Pearson correlation coefficient, threshold μ, and variance inflation factor. We further compared the performance of SPV-based, stepwise feature selection (SFS)-based, and least absolute shrinkage and selection operator (LASSO)-based AGB models developed with different regression approaches that were sensitive to strong collinearity. Field-measured data and corresponding ALS data, acquired from 1002 sample plots distributed across four distinct forest types within the Guangxi Zhuang Autonomous Region in Southern China, were used to evaluate variable selection techniques and develop AGB models. Results indicated that ALS variables selected by SPV exhibited weaker collinearity compared to those selected by SFS and LASSO. SPV-based AGB models outperformed SFS-based AGB models with higher leave-one-out cross-validation adjusted R2 (LOOCV Radj2) by 0.1% − 27.8%. SPV-based AGB models outperformed LASSO-based AGB models with higher LOOCV Radj2 by 0.4% − 16.3%. Hence, for variable selection in constructing AGB models (linear regression model, log–log regression model, and generalized additive model (GAM)) based on strongly collinear ALS variables, SPV is most preferred, followed by SFS and LASSO. The smooth curves from our GAMs developed using SPV-selected variables revealed that five canopy height variables (whp40, hmean, hp25, hp70, hskew), one canopy density variable (whp85), three density-related variables (nVegPts, bcc, and mcc), and one vertical structural variable (LADmean) were positively correlated with AGB. The canopy height variables (whp40, hmean, hp25, and hp70) were identified as the most important variables in estimating AGB for four forest types. The canopy density variable wdp85 showed a strong effect on AGB of the coniferous forests, whereas it had almost no effect on the AGB of broadleaved forests. Overall, this manuscript proposes a novel variable selection algorithm named SPV, aimed at addressing collinearity of variables derived from ALS data, which has significant implications for the application of ALS in forest inventory and forest modeling.

Zircon U-Pb geochronology, major, trace elemental, and Sr-Nd-Pb isotopic geochemistry: constraints on the age and magmatic origin of Mesozoic mafic dykes in the Guangxi Zhuang Autonomous Region, South China

ABSTRACT As a direct product of lithospheric extension, the mafic dyke group have become an ideal object for studying the formation, evolution and dynamics of both the crust and continental orogenic belts. Given the scientific significance of mafic dykes and their utility in addressing outstanding questions concerning the origin and development mafic dyke swarms Mesozoic age with-in the South China Plate, in this study, 54 representative mafic dykes within the Guangxi Zhuang Autonomous Region, South China, were examined. Research methods include laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) U-Pb age-dating, whole rock geochemistry, and the Sr-Nd-Pb isotope geochemistry of the studied mafic dykes. The results indicate that these rocks formed between 139 Ma and 113 Ma and have typical doleritic and lamellar textures. They fall into the alkaline and shoshonitic series, are characterized by enrichment of light rare earth elements, some large ion lithophile elements (Rb, Ba, and Sr), Th, U, and Pb, and have depleted Nb, Ta, Hf, and Ti. Moreover, the mafic dykes studied have high initial87Sr/86Sr ratios (0.7055–0.7057), negative εNd(t) values (from −15.2 to −11.4), and relatively constant initial Pb isotopic ratios (that are Enriched Mantle-1 (EM I)-like; 206Pb/204Pb = 16.765–16.816, 207Pb/204Pb = 15.429–15.476, and208Pb/204Pb = 36.882–37.144). The above results indicate that the group of dolerites and lamprophyres studied herein were likely derived from magma generated via low-degree partial melting (1.0%–10%) of an EM1-like garnet-lherzolite mantle source. The parental magmas to these fractionated olivine-, clinopyroxene-, plagioclase, and Ti-bearing phases, with negligible crustal contamination during ascent and dyke emplacement. On the basis of existing research and evidence from this study, we propose a reasonable model for the origin of the mafic dykes: the ancient Pacific Plate subducting below the South China plate led to extension of the lithosphere, an upsurge of the asthenosphere, which triggered partial melting of the lower mantle lithosphere in the Early Cretaceous, and the formation of the parent magma to the Mesozoic mafic dykes in the Guangxi Zhuang Autonomous Region study area. The involvement of slab-derived fluids from the subduction of the ancient Pacific Plate was responsible for metasomatism of the mantle source to these mafic magmas.

Rural Industry Revitalization Can Be Energized by Land Transfer: A Case Study in Guangxi Zhuang Autonomous Region, China, 2013–2022

The Chinese government has vigorously promoted the transfer of land use rights, aiming to promote the scale, intensification, and efficiency of agricultural operations and achieve rural industry revitalization (RIR). However, whether and how land transfer energizes RIR remains unclear. Taking five representative cities (Nanning, Guigang, Baise, Fangchenggang, and Guilin) in Guangxi Zhuang Autonomous Region as a case study, we quantificationally characterized RIR during 2013–2022 using eleven variables and land transfer using three difference indices. We evaluated the contribution of land transfer to RIR and compared it among cities. Results showed that all five cities in Guangxi displayed an increasing trend of land transfer and RIR over the last decade. The increase in RIR was largely contributed by the improvement in infrastructure construction and industry convergence, and, to a lesser extent, by the enhancement in agricultural production efficiency. There was a strong city-specific correlation between RIR and the land transfer indices, indicating a beneficial role of land transfer in RIR. Structural equation modeling further indicated that land transfer promoted RIR, likely through facilitating infrastructure construction, enhancing industry convergence, and improving agricultural production efficiency. These results provide strong evidence that the transfer of land use rights can promote RIR and practical reference for advancing farmers’ well-being and the overall goal of rural revitalization in the future. The framework and the methodology proposed here are applicable elsewhere in China and other countries where scattering allocation of land resources represents a key limitation to agricultural production and economic development.

The correlation between healthy lifestyle habits and all-cause and cardiovascular mortality in Guangxi

BackgroundAdherence to healthy lifestyle habits has become a mainstream approach for lessening the burden of cardiovascular disease (CVD) during initial prevention efforts. The purpose of this study was to investigate the prevalence of four healthy lifestyle habits, the associated factors, and their impact on all-cause and cardiovascular mortality among residents of Guangxi Zhuang Autonomous Region.MethodsFrom 2015 to 2019, individuals between the ages of 35 and 75 from Guangxi Zhuang Autonomous Region were recruited through the ChinaHeart Million Person Project. Our study examined four healthy lifestyle habits: not smoking, no or moderate amounts of alcohol, sufficient leisure time physical activity (LTPA) and a balanced diet.ResultsOut of the 19,969 individuals involved, the majority, 77.3% did not smoke, while 96.7% had limited alcohol intake, 24.5% engaged in sufficient LTPA, 5.5% followed a balanced diet, and merely 1.7% adhered to all four healthy lifestyle habits. Participants who were women, older, nonfarmers, living in cities, with a high income or level of education, or had hypertension or diabetes were more likely to follow all four healthy lifestyle habits (p < 0.001). People who followed the three healthy lifestyle habits had reduced chances of death from all cause (HR 0.34[95% CI:0.15,0.76]) and cardiovascular-related death (HR 0.23 [95% CI: 0.07, 0.68]) (p < 0.01) over a median period of 3.5 years.ConclusionsIn Guangxi Province, the level of adherence to healthy lifestyle habits is very minimal. Therefore, population-specific health promotion strategies are urgently needed.

Unveiling the dynamic evolution of comparative advantage: assessing the competitiveness of China’s main winter and spring vegetable production regions

IntroductionChina is the world’s largest producer and consumer of vegetables, with all provinces, cities, and autonomous regions cultivating vegetables. The main production areas for winter and spring vegetables have higher accumulated temperatures, allowing for multiple planting seasons throughout the year. Therefore, this article examines the competitiveness of vegetable production in China’s main winter and spring vegetable producing areas from the perspective of the dynamic evolution of comparative advantages.MethodsDrawing on statistical data from 2000 to 2018 on the development of the vegetable industry in these key provinces, our analysis incorporates methods such as the Resource Endowment Coefficient, the Comprehensive Comparative Advantage Index, the entropy method, and systematic cluster analysis to explore the evolution of competitive advantages in vegetable production across various provinces and cities.Results and discussionThe findings reveal significant regional disparities in resource endowments and overall advantages in vegetable production during the winter and spring seasons. Notably, Chongqing, Hubei Province, and Shanghai exhibit a Resource Endowment Factor (EF) averaging above 1, indicating a relative abundance of production resources and a comparative advantage. Similarly, Hainan Province, the Guangxi Zhuang Autonomous Region, Guangdong Province, Fujian Province, Shanghai, and Zhejiang Province each demonstrate an average Comprehensive Advantage Index (AAI) exceeding 1, affirming their comprehensive comparative strengths. Overall, the competitiveness of vegetable production in these regions exhibits a fluctuating yet ascending trend, with notable disparities in competitive strengths across different areas. The ranking of annual average competitiveness scores in vegetable production is as follows: Shanghai &amp;gt; Zhejiang &amp;gt; Hubei &amp;gt; Hunan &amp;gt; Guangdong &amp;gt; Sichuan &amp;gt; Chongqing &amp;gt; Fujian &amp;gt; Guangxi &amp;gt; Jiangxi &amp;gt; Hainan &amp;gt; Yunnan. Based on these outcomes, the study proposes tailored strategic recommendations for provinces and cities according to their unique resource endowments and comparative advantages, aiming to enhance the sector’s productivity and competitive stance.

Volatiles and bacterial composition of pickled bamboo shoots within 10 pre-packaged Chinese Luosifen disclosed by GC–MS, GC-IMS, and high-throughput sequencing

Pickled bamboo shoots represent a type of fermented bamboo shoot product. In China, pickled bamboo shoots are regarded as the soul of Luosifen, which is a local specialty food in Liuzhou (Guangxi Zhuang Autonomous Region, China). To exemplify the uniqueness of the pickled bamboo shoots, we analyzed the pickled bamboo shoots within 10 pre-packaged Chinese Luosifen to determine the composition of volatiles and bacteria, and subsequently examined the correlation between them. The volatiles were identified using gas chromatography–mass spectrometry (GC–MS) and gas chromatography-ion mobility spectrometry (GC-IMS). Meanwhile, high-throughput sequencing technology was employed to investigate the bacterial composition. The results indicated that the pH values of the samples exhibited minimal variance (ranging from 3.71 to 4.53), while the total acid (measured as g lactic acid /L) varied (from 4.65 to 10.3 g lactic acid /L). Lactic acid, acetic acid, and succinic acid were the predominant organic acids. 50 volatiles were detected by HS-GC-MIS, and 108 volatiles were identified by HS-SPME-GC–MS. p-Cresol (76,541.67 < OAV < 248,166.67), acetic acid (482.31 < OAV < 1164.62), and hexanoic acid (108.33 < OAV < 1333.33) were the common distinctive volatiles among the 10 samples. Proteobacteria and Firmicutes, as the dominant phyla, were positively and negatively related to 1-butanol (R = 0.66, − 0.66), respectively. Industrial relevanceIn China, Luosifen, as a local delicacy, enjoys popularity among the public for its sour, smelly, spicy, fresh, and oily features. Among them, pickled bamboo shoots are highly sought after for their distinctive sour and refreshing flavor. Nevertheless, some individuals cannot tolerate the sour smell of pickled bamboo shoots yet still have a desire to consume Luosifen. To address this issue, it is crucial to determine what constitutes the pungent odor in pickled bamboo shoots and subsequently regulate it to meet the requirements of diverse consumers and enhance the economic benefits of the Luosifen industry. This study disclosed the stimulant flavor substances of pickled bamboo shoots in 10 pre-packaged Luosifen detected by GC–MS and GC-IMS, offering a theoretical foundation for subsequent regulation.

The study suggests that incorporating traditional instruments like the Dong Pipa into modern educational practices can enhance cultural literacy and support preservation efforts.

A case report of disseminated cysticercosis in Guangxi Zhuang Autonomous Region, Southwest China

BackgroundCysticercosis is a zoonotic parasitic disease that poses a serious threat to public health. It is widely distributed and has a high incidence rate in China. Reports of disseminated cysticercosis worldwide are rare. This article presents a case of disseminated cysticercosis in the Guangxi Zhuang Autonomous Region of southwestern China.Case presentationThe patient, a 46-year-old male belonging to the Miao ethnic group, hailed from a region in Guangxi Zhuang Autonomous Region known for its high incidence of cysticercosis. He had a habit of consuming raw pork and beef. With a history of recurrent consciousness disturbances and limb convulsions for five years, he presented with headaches and dizziness nine days prior. Comprehensive examinations were conducted on the patient. Ultimately, based on epidemiological history, imaging findings, pathogen testing, and pathological results, he was diagnosed with disseminated cysticercosis. Following anthelmintic treatment, the patient was discharged with clear consciousness, free from headaches, dizziness, nausea, vomiting, and seizures. The patient is currently under follow-up care.ConclusionIt is crucial to enhance public awareness, promote health education, and cultivate good hygiene habits, as these are essential measures in reducing the incidence of cysticercosis.

Integrated risk assessment of landslide in karst terrains: Advancing landslides management in Beiliu City, China

Beiliu City, Guangxi Zhuang Autonomous Region, China, like other karst landscape areas, is also suffering from the threat of landslides. This research applied the circular variance method to delineate 31,465 slope units and then combined it with a geographic information system and a well-established risk assessment system to synthesize three perspectives-susceptibility, hazard, and vulnerability to realize the risk assessment of karst landslides in Beiliu City. Using perennial field surveys, aerial images-derived landslide inventories, slope unit investigations, and a literature review combined with a Fully Convolutional Neural Networks approach, we present a culminating in the derivation of landslide susceptibility assessment outcomes within the study area. Because Beiliu City is located in a karst area, this research employs the quantification of soil erosion intensity as a metric to assess landslide hazard. In this study, based on a comprehensive analysis of the basic characteristics of landslides and their associated disaster-bearing bodies, a robust landslide vulnerability assessment index system was constructed for risk assessment of karst landslides in Beiliu City. The landslide risk assessment model in karst area is constructed by combining the landslide susceptibility and the vulnerability in the danger range. Detailed field surveys verified the scientific validity and accuracy of the assessment results. This research extends beyond merely furnishing scientific data support for local governmental efforts in disaster prevention and mitigation. It impressively enhances the methodological framework for conducting landslide risk assessments within karst landscapes, thereby offering a robust foundation for both immediate and strategic responses to the inherent geological vulnerabilities of these areas.

Association between Copper Exposure and Cognitive Function: A Cross-Sectional Study in a County, Guangxi, China.

There has been growing attention to the impact of copper exposure on cognitive function; however, current research on the specific information regarding urinary copper and cognitive function is limited, particularly detailed analyses in the Chinese adult population. This study aimed to explore the association between copper exposure and cognitive function in a cross-sectional design. A total of 2617 participants in a county, Guangxi Zhuang Autonomous Region (Guangxi), China, were included. The mini-mental state examination (MMSE) was used to assess cognitive function, and inductively coupled plasma mass spectrometry was used to measure urinary metal levels. Spearman's rank correlation was used to analyze the correlation between urinary copper levels and various cognitive function assessment indices. After adjusting for potential confounders, binary logistic regression was used to explore the association between urinary copper levels and the risk of cognitive impairment (CI) as revealed by MMSE, and restricted cubic spline regression was further used to explore the dose-response relationship. The results showed a negative correlation between urinary copper levels and orientation, attention and calculation, memory, language ability, and MMSE total scores (P < 0.05). Compared with the low copper exposure group, the high exposure group showed a 58.5% increased risk of CI (OR = 1.585, 95%CI: 1.125 to 2.235, P = 0.008). A significant linear dose-response relationship was observed between urinary copper levels and the risk of CI (P overall = 0.045, P nonlinearity = 0.081). Our findings suggest that higher copper exposure may be associated with CI in the population of a county, Guangxi, China.

Predictive analysis of college students’ academic procrastination behavior based on a decision tree model

Predicting academic procrastination among college students in the context of a public crisis could provide essential academic support and decision-making strategies for higher education institutions to promote student psychological health. Notably, research focusing on predicting academic procrastination behavior among college students in the context of a global crisis is still limited. The purpose of this study is to address this gap by constructing a predictive model based on the decision tree algorithm to predict academic procrastination behavior among college students. A total of 776 college students from the Guangxi Zhuang Autonomous Region of China participated in this study. The study gathered data from multiple aspects relevant to academic procrastination behavior, including demographic information, academic achievements, subjective well-being, smartphone addiction, negative emotions, self-esteem, life autonomy, pro-environmental behavior, academic achievement, and sense of school belonging. Descriptive statistical analysis was conducted utilizing SPSS version 26.0, and decision tree model analysis was performed with Modeler 18.0. The findings of this study identified eight predictive factors of college students’ academic procrastination in order of importance: subjective well-being, smartphone addiction, negative emotions, self-esteem, life autonomy, pro-environmental behavior, academic performance, and sense of school belonging. The model accuracy was 85.78%, and indicating a relatively high level of prediction. The findings of this study not only provided a new perspective for understanding academic procrastination but also offered practical guidance for educators on how to mitigate this behavior.

A dataset of social-economic and environmental parameters at township and county levels in Guangxi Zhuang Autonomous Region

Guangxi Zhuang Autonomous Region is located in the southwest of China, boasting rich natural ecological resources and diverse social and cultural backgrounds. To carry out sustainable development research in the provincial (regional) area, it is essential to have accurate socio-economic and environmental data at township and county levels across spatial and temporal scales. In this study, we gathered environmental, infrastructure, and industrial and agricultural production data from various sources, and produced the environmental parameter data, infrastructure and industrial and agricultural production data for 1,241 township units through extracting parameters and superposing township boundary vectors with environmental parameters, infrastructure data as well as industrial and agricultural production raster data. Additionally, based on the statistical yearbook of Guangxi issued by Guangxi Zhuang Autonomous Region Statistical Bureau, we compiled the socio-economic data for 111 counties in Guangx, resulting in the formation of a dataset of social-economic and environmental parameters at township and county levels in Guangxi Zhuang Autonomous Region. The dataset maintains the accuracy of the original data and meets the requirements for data completeness, positional accuracy, and attribute accuracy, as verified by multiple reviewers in accordance with relevant technical regulations and standards. This dataset is publicly available, featuring a long time series and multiple types. The parameter dimensions as well as the spatial and temporal dimensions of the dataset can be expanded, providing data support for sustainable development in the region at multiple scales.

A new species of the stonefly genus Neoperla Needham, 1905, Neoperla xuanena sp. n., is described from southwestern Hubei Province of China. Paragnetina insignis Banks, 1939 is redescribed on the basis of male specimen from northeastern Guangxi Zhuang Autonomous Region of China, and the aedeagus of this species is described for the first time. http://zoobank.org/urn:lsid:zoobank.org:pub:02FE17BD-D99D-403E-86C3-7B6177CADC07

Sinobdella longitubulus, a new species of spiny eel (Pisces, Mastacembelidae) from the Zhu-Jiang Basin, with a note on the type locality of S. sinensis (Bleeker, 1870)

The spiny eel genus Sinobdella belongs to the family Mastacembelidae of the order Synbranchiformes. Kottelat and Lim (1994) utilised Rhynchobdella sinensis as the type species to propose the genus. Currently, it contains a single species widespread in eastern and southern China and northern Vietnam. Sinobdella longitubulus, a new species of spiny eel, is here described from the Xi-Jiang of the Zhu-Jiang Basin in Guangxi Zhuang Autonomous Region, southern China. It differs from the single congeneric species S. sinensis in having a more or less white-brown reticulated pattern on the flank, two tubular anterior nostrils longer than or equal to the rostral appendage, an anal fin heavily mottled with dark brown markings and white spots and bearing a narrow white distal margin; shorter pre-anal length; and fewer abdominal vertebrae. The validity of this new species is corroborated by its monophyly recovered in a COI gene-based phylogenetic analysis and its significant sequence divergence with S. sinensis. A note on the type locality of S. sinensis is also given; its type specimen is possibly from mountain streams of Jiangxi Province, in the lower Chang-Jiang Basin.

Entomophagy and entomo-therapeutic practices in a mountainous territory in southeast Guangxi Zhuang Autonomous Region, China

BackgroundAlthough China has a long history of using insects as food and medicine and has developed numerous associated knowledge and practices, especially in its rural and mountainous areas, systematic surveys concerning this subject are limited. In-depth ethnobiological research is needed to compile a comprehensive database of edible and medicinal insects and record the associated knowledge of these food and medicinal resources.MethodsData on edible and medicinal insects and associated knowledge about them were collected by interviewing 216 local villagers in a mountainous territory in southeast Guangxi Zhuang Autonomous Region, China.ResultsLocal villagers used at least 16 edible and 9 medicinal insects, of which 4 wasp species were used in both entomophagy and medicinal practices. Parapolybia varia, Polistes olivaceus, and Anomala chamaeleon were newly recorded edible insects in China. The wasps, Euconocephalus sp., Gryllotalpa orientalis, and Cyrtotrachelus longimanus, were preferred and culturally important edible insects. Populations of Euconocephalus sp. and G. orientalis were reported to have substantially decreased in recent years. Wasps and a bamboo bee were used to treat rheumatism, while cockroaches and antlions were used to treat common cold symptoms in infants. Insect-related knowledge was positively correlated with the interviewees’ age.ConclusionsVillagers have accumulated considerable local and traditional knowledge of entomophagy and entomo-therapeutic practices. However, this knowledge is in danger of being lost, which highlights the urgent need to document this information. Edible insects enrich local diets, and a more sustainable supply (such as through insect farming) could maintain local entomophagy practices. Medicinal insects are a part of local folk medicine, and pharmacological and chemical techniques could be applied to identify various biologically active substances in these insects.
