Special Issue Information

Dear Colleagues,

Vector-borne diseases are no longer restricted by borders, climates, or seasons. In a rapidly changing world, climate warming, shifting rainfall patterns, and accelerated environmental transformations are expanding the habitats of disease vectors, creating unprecedented opportunities for pathogens to invade new territories. These shifts are rewriting the global map of disease risk, often faster than our ability to respond.

At the heart of this challenge lies a complex and dynamic network constituting hosts, vectors, pathogens, and the environment, locked in constant interaction. Understanding the relationships within this network is not simply an academic exercise; it is the foundation for predicting outbreaks, protecting vulnerable populations, and designing effective, sustainable interventions.

This Special Issue seeks to bring together cutting-edge research and integrative reviews that illuminate these ecological dynamics and point toward innovative solutions. By bridging disciplines—from field ecology and molecular biology to epidemiology, climate science, and public health—we aim to generate knowledge that can inform action in the face of a growing global threat.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Biology is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Phlebotomine sand flies remain poorly studied in southeastern Peru, a region with a high burden of cutaneous leishmaniasis (CL). Using modified ultraviolet (UV) light traps, we surveyed sand fly assemblages at Manu Biological Station during the wet season within secondary forest, Guadua bamboo forest, fruit crop plots, and peridomicile habitats. We collected 2641 sand flies representing 32 species. Habitat type was the primary driver of assemblage composition, with minimum nightly temperature as the strongest environmental correlate. Sand fly abundance was highest in secondary forest (n = 921) and peridomicile habitats (n = 836), where assemblages were dominated by Nyssomyia shawi, a generalist species. Although Guadua bamboo forests harbored lower abundance (n = 386), potential vector species comprised 92% of the assemblage compared to 42–86% in other habitats, suggesting that expanding bamboo forests may favor a higher proportion of potential CL vectors. Peridomicile assemblages consisted largely of generalist species that overlapped with adjacent forested habitats, indicating potential pathways for sylvatic-to-peridomestic spillover. Although the study’s limited scope (i.e., limited to a single season and locality) does not allow broad generalization, our findings suggest the importance of habitat in structuring patterns of potential vector exposure.

Malaria remains a major public health issue worldwide and a repeated cause of illness and death in tropical and subtropical areas. It is caused by protozoan parasites of the genus Plasmodium and transmitted through bites of infected female Anopheles mosquitoes, but it can also be transmitted via blood transfusions, organ transplants, and congenitally from mother to child. Despite decades of intervention efforts, millions of new cases and hundreds of thousands of deaths still occur each year, primarily in low- and middle-income countries. This review summarizes current epidemiological data on the global burden of malaria, mainly from the World Health Organization’s (WHO) World Malaria Report 2024 and Global Burden of Disease estimates. It brings together the latest evidence on worldwide malaria epidemiology, regional trends, determinants, and control strategies, with a particular focus on socio-economic factors, intervention methods, and emerging challenges such as drug resistance, climate change, and limited funding. Disease prevention and management require global, multifactorial approaches that are tailored to the local environment. Strengthening health education with locally relevant knowledge is important to improving outcomes in primary health prevention, secondary health prevention, and tertiary health prevention. The review concludes with a discussion of policy priorities needed in the future to meet the WHO Global Technical Strategy goals for malaria elimination by 2030. Full article
