Interaction between mosquito (Diptera: Culicidae) diversity and phytotelmata used as traps in an Atlantic forest ecosystem, state of Rio de Janeiro, Brazil

Frontiers in Ecology and Evolution
The structural complexity of host plants plays a significant role in shaping the heterogeneity of phytotelmata, influencing the taxonomic composition and ecological dynamics of associated communities, including medically important organisms such as ...

Environmental suitability for Lutzomyia (Nyssomyia) whitmani (Diptera: Psychodidae: Phlebotominae) and the occurrence of American cutaneous leishmaniasis in Brazil

Parasites & Vectors, 2018
Background Leishmaniasis represents an important public health problem in Brazil. The continuous process of urbanization and expansion of human activities in forest areas impacts natural habitats, modifying the ecology of some species of Leishmania, as ...

Lack of Evidence for Natural Wolbachia Infections in Aedes aegypti (Diptera: Culicidae)

Journal of medical entomology, 2018
Wolbachia is a genus of endosymbiotic bacteria that infects 66% of all insect species. Its major impact on insects is in reproduction: sterility, production of one sex, and/or parthenogenesis.

A roadmap to key traits of invasive Drosophilidae

Biological Reviews, EarlyView.
ABSTRACT Biological invasions have intensified in recent decades, mostly driven by international trade and travel, raising significant concerns, particularly regarding insect pests. Once non‐native species establish, they can disrupt natural ecosystem stability, undermine agroecosystem sustainability and cause substantial economic losses.

Characterization of External Female Genitalia in Five Triatoma Laporte Species of South America (Hemiptera: Reduviidae: Triatominae)

Tropical Medicine and Infectious Disease, 2023
Currently, there are 158 valid species of triatomines, all of which are potential vectors of Trypanosoma cruzi, the etiological agent of Chagas disease.

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

First description of the male of Volesus nigripennis Champion, 1899, with new records from Ecuador and Panama, taxonomical notes, and an updated key to the genera of Sphaeridopinae (Hemiptera, Reduviidae) [PDF]

ZooKeys, 2019
The genus Volesus Champion, 1899 is redescribed and the male of V. nigripennis Champion, 1899 is described for the first time and found to be similar to the female in both structure and coloration.

Comprehensive inventory of true flies (Diptera) at a tropical site

Communications Biology, 2018
Estimations of tropical insect diversity generally suffer from lack of known groups or faunas against which extrapolations can be made, and have seriously underestimated the diversity of some taxa. Here we report the intensive inventory of a four-hectare

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Assessment of the Variation in Faunistic Parameters of Mosquitoes (Culicidae: Diptera) Across Different Forest Gradients in the Tijuca National Park Area, Rio de Janeiro, Brazil

Diversity
The assessment of mosquito diversity in remnants of the Atlantic Forest, which are considered biodiversity hotspots, is crucial for studying patterns of behavior and adaptation, performing environmental monitoring, and public health.
