Aedes aegypti (Ae. aegypti) is the primary vector for dengue, Zika and chikungunya, which represent major global public health concerns. The use of Wolbachia as a biological control agent in Ae. aegypti has gained significant international attention following the successful establishment of field-released mosquitoes in Australia, Malaysia, Brazil, Indonesia and Singapore. This study presents a comprehensive scientometric analysis of the research landscape of Wolbachia and Ae. aegypti. Data comprising 662 English-language publications from 2000 to 2025 were extracted from the Scopus database. Analytic tools, including VOSviewer and R-based Biblioshiny, were employed to quantify author productivity, transcontinental collaboration networks, thematic evolution, research gaps and future directions, while Bradford’s Law of Scattering was used to identify core dissemination channels. Publications have shown a steady upward trajectory since 2000, with an overall relative growth rate of 0.3%, while annual citations peaked in 2009 and 2011 (3337 and 3460 citations, respectively). The dataset strictly conformed to Bradford’s distribution (0.16% error), identifying PLOS Neglected Tropical Diseases (11.9%) and Parasites and Vectors (5.6%) as the core journals. Global research networks are predominantly led by Australia and the United States, supported primarily by the National Institutes of Health (14.8%) and the National Health and Medical Research Council (14.2%). Crucially, thematic analysis using a methodological triangulation approach demonstrates a progressive maturation in the field, shifting from foundational laboratory mechanisms toward large-scale deployment logistics and microbiome dynamics. Overall, this study highlights the intellectual landscape, underscores the vital role of global collaboration, and provides strategic insights to guide future evidence-based policies in Wolbachia–Aedes aegypti research.

Introduction: The prevalence of youth e-cigarette use has risen markedly, while traditional cigarette smoking rates have declined in recent years. Restricting access to electronic cigarettes (ECs) is regarded as a potential strategy to reduce their use among adolescents. However, there is a...

BACKGROUND Aedes aegypti is one of the vectors of dengue, Zika and Chikungunya. The use of Wolbachia as a biological control agent in Aedes aegypti has gained significant global attention following the successful establishment of field-released mosquitoes in Australia, Malaysia, Brazil, Indonesia and Singapore. OBJECTIVE This study presents a scientometric analysis of research on Wolbachia and Aedes aegypti, and quantifying key findings. METHODS Data were extracted from the Scopus database, including English-language articles, reviews, books and book chapters published between 2000 and 2025. Relative growth rate was generated to examine the change in the number of publications per year. Analysis tools such as Vosviewer, CiteSpace, and the R-based Biblioshiny were employed to examine prolific authors, publication and citation trends, collaboration networks, and thematic evolution. Bradford’s Law analysis was used to examine the core journals that contribute most to the dissemination of research in this area. RESULTS The findings reveal that Ary Hoffmann is the most prolific author, while Australia leads as the most productive country. Research activity across 13 thematic clusters has intensified over time, with emerging focus areas including “prevalence distribution”, “Wolbachia strain” and “Wolbachia-mediated sterility”. The low percentage of error (0.6%) suggests that the data fits the Bradford’s distribution pattern, with PLoS Neglected Tropical Diseases (79) and Parasites and Vectors (39) as top journal. CONCLUSIONS Overall, the study provides a comprehensive overview of the intellectual landscape, collaboration patterns, and emerging trends in Wolbachia-Aedes aegypti research, underscoring global collaboration and emerging trends that have the potential to advance innovative and sustainable approaches to vector control for dengue and other arboviral diseases.

BACKGROUND Malaysia is recognized as a leading contributor to global malaria research, especially after the identification of Plasmodium knowlesi as a significant zoonotic agent of human malaria. OBJECTIVE Comprehensive bibliometric analyses assessing research volume, collaborative networks, and thematic evolution in Malaysian malaria research remain limited. METHODS This scientometric study examined malaria-related publications from Malaysia indexed in Scopus between 1956 and 2024. A total of 674 records were analyzed using descriptive statistics, collaboration metrics, citation analysis, and bibliometric laws, including Lotka's, Bradford's, and Zipf's. VOSviewer was utilized to generate visual networks of authors, institutions, countries, keywords, and their interrelationships. RESULTS Research output was limited until the late 2000s, then grew at an average annual rate of 11.88%, peaking in 2022. Collaboration was strong (coefficient 0.66), with Malaysia serving as a central hub connecting Australia, United Kingdom, United States, and other Asian countries. Author productivity was skewed, deviating from Lotka’s Law, while a core set of journals, led by Malaria Journal, dominated publication in line with Bradford’s Law. Keyword analysis, following Zipf’s Law, highlighted clinical management, P. knowlesi diagnostics, and epidemiology as key research themes. CONCLUSIONS The rapid expansion of Malaysian malaria research is marked by a strong thematic focus and robust international collaboration, particularly in zoonotic malaria. To support malaria elimination objectives and strengthen the broader One Health and biomedical research ecosystem, increased institutional participation is recommended to ensure the sustainability of future interdisciplinary research.
