Special Issue Information

Dear Colleagues,

Insects are by far the most diverse class of arthropods. Within the class, Diptera is the second most diverse order, with diversity of more than 170 thousand species cataloged thus far in mid-2024 (catalogue of life). Despite the immense number of species already described, more conservative estimates indicate that this number is still greatly underestimated, especially in the Tropics. Furthermore, studies on phylogenetic relationships, cryptic species, ecological aspects, evolution, and biogeography are still poorly known for most Dipterans. This Special Issue, “Ecology and Diversity of Diptera in the Tropics”, aims to provide an opportunity to publish high-quality original papers and reviews on the diversity, phylogeny, and ecology of tropical Diptera.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Diversity is an international peer-reviewed open access monthly 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 2100 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Vector-borne diseases (VBDs) remain a major public health burden, particularly in tropical and subtropical regions. Aedes aegypti mosquitoes are primary vectors of several VBDs, and understanding their population dynamics is critical for developing effective control strategies. This study investigates seasonal sex ratio variation in A. aegypti populations within urban environments of El Salvador’s seasonally dry neotropical biomes. Using data from an ongoing surveillance program, we analyzed the temporal distribution of male and female mosquitoes across eight sampling events. Our results reveal significant deviations from the expected 1:1 sex ratio, with a pronounced female bias during the dry season and a shift toward parity in the wet season. These findings suggest that environmental and anthropogenic factors influence sex ratio dynamics, potentially affecting reproductive success and population persistence. The observed sex ratio distortion has important implications for vector ecology and biocontrol, emphasizing the need to incorporate seasonal and urban ecological variation into vector management strategies. Integrating these ecological insights into biocontrol programs could enhance the effectiveness of interventions aimed at reducing VBD transmission in seasonally dry tropical regions. Full article

Cocoa (Theobroma cacao L.) relies on insect pollination for fruit production, making it essential to understand the pollinators involved. This study aimed to identify the insects associated with cocoa pollination and their relationship with effective natural pollination in a cocoa agroforestry system in Yopal, Colombia. Indirect (wood traps) and direct (manual aspiration in flowers) methods were used to capture pollinators. The number of captured insects was correlated with the percentage of pollinated, fertilized, aborted, and transitioning flowers using Pearson’s correlation coefficient. Additionally, the natural transfer of pollen was assessed by evaluating the coverage of near-opening flowers and staining pollen grains on the stigma under natural conditions. This study identified Diptera from the Ceratopogonidae family, specifically the genera Forcipomyia and Dasyhelea, as key pollinators. The findings highlight the presence of these pollinators in the Yopal cocoa agroforestry system and suggest the need for further pollinator capture and identification efforts on local farms. A positive correlation was found between the number of pollinating insects and the percentage of fertilized flowers, emphasizing the crucial role of these insects in cocoa pollination and the importance of promoting their presence to optimize fruit production.
