Beyond birds: rethinking bird‐centered pathogen models in light of insect migration

Ecography, EarlyView.
Migration redistributes biomass, nutrients, and pathogens across ecosystems. For decades, migratory birds have been treated as the default long‐distance pathogen vectors, shaping both conceptual frameworks and empirical models of disease ecology.

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.

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

Aspects of the blood meal of mosquitoes (Diptera: culicidae) during the crepuscular period in Atlantic Forest remnants of the state of Rio de Janeiro, Brazil

Frontiers in Ecology and Evolution
Identifying their food sources provides insights into mosquito foraging behaviors and directly impacts the epidemiology of mosquito-borne pathogens such as dengue, Zika, and chikungunya.

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 ...

Bamboo (Poales, Poaceae): An Important Maintainer of Immature Mosquitoes (Diptera: Culicidae) in a Biodiversity Hotspot in the City of Rio de Janeiro, Brazil

Life
Although tropical forests are home to most of the global diversity, they suffer from the most significant knowledge gaps concerning their fauna. Despite its high biodiversity, Brazil is facing an alarming destruction of habitats, with species becoming ...

New records of associations between species of Reduviidae (Hemiptera: Heteroptera) and plants in Argentina

Revista Chilena de Entomología, 2022
Almost all reduviids are predators; however, recent observations have shown that certain reduviids, particularly members of tribe Harpactorini (Harpactorinae) may be associated with specific plants as a strategy of predation and complementary nectarivory.

Understanding the effects of patch‐burn grazing management on aboveground grassland invertebrate biodiversity

Oikos, EarlyView.
Landscape heterogeneity is widely recognized as a driver of biodiversity, yet its consequences for above‐ground, foliage‐dwelling insect communities under active grassland management remain underexplored. Patch‐burn grazing (PBG), which rotates fire across patches within a grazed landscape, is designed to promote spatial and temporal heterogeneity by ...
