Abstract The Aedes aegypti mosquito is generally associated with arboviruses that cause yellow fever, dengue, zika and chikungunya. most efficient way to control their populations through application in breeding sites of highly toxic insecticides can also impact non‐target organisms generate resistant populations. Therefore, the use compounds desirable.

Harnessing traits to predict economic impacts from biological invasions

Trends in Ecology & Evolution, Journal Year: 2025, Volume and Issue: unknown

Published: April 1, 2025

Biological invasions stand among the main anthropogenic threats to ecosystems globally while causing multitrillion-dollar impacts. Surprisingly, trait-based frameworks have been designed predict invasion success and invader ecological impacts, no such approaches exist understand economic We propose first framework by bridging evolutionary biology of traits escalation costs. Previously acquired can benefit performance, their rapid change could exacerbate impacts through adaptive non-adaptive processes during invasion, as natural selection, genetic drift, or phenotypic plasticity. Emerging evidence suggests that some organismal determine impact magnitudes. discuss new transdisciplinary avenues inform cost forecasting management responses for current future biological invasions.

The incidence of climate-sensitive infectious diseases (CSIDs), such as dengue, chikungunya and Zika, has been rising in Latin America the Caribbean (LAC). Reported cases these nearly doubled between 2022 2023, with highest figure reported from Brazil. However, evidence regarding economic cost CSIDs is limited region. This scoping review aims to identify available on impacts LAC countries potential costs benefits adaptation interventions.

Context-specific variation in life history traits and behavior of Aedes aegypti mosquitoes

Frontiers in Insect Science, Journal Year: 2024, Volume and Issue: 4

Published: Sept. 25, 2024

Aedes aegypti , the vector for dengue, chikungunya, yellow fever, and Zika, poses a growing global epidemiological risk. Despite extensive research on Ae. ’s life history traits behavior, critical knowledge gaps persist, particularly in integrating these findings across varied experimental contexts. The plasticity of throughout its cycle allows dynamic responses to environmental changes, yet understanding variations within heterogeneous study designs remains challenging. A aspect often overlooked is impact using lab-adapted lines which may have evolved under laboratory conditions, potentially altering their behavioral compared wild populations. Therefore, incorporating field-derived populations essential capture natural variability adaptability . relationship between larval conditions adult behavior significantly influenced by specific context mosquitoes are studied. Laboratory not replicate ecological complexities faced populations, leading discrepancies observed behavior. These highlight need ecologically relevant allowing mosquito reflect field distributions. One effective approach semi-field studies involving field-collected housed fewer generations lab conditions. This trend provides researchers with desired control over while maintaining genetic diversity By focusing contexts, this review highlights intricate It underscores significance transstadial effects necessity adopting reporting practices that acknowledge considering due rearing Embracing such approaches paves way comprehensive contextual integrated perspective enables synthesis laboratory, semi-field, field-based investigations, crucial devising targeted intervention strategies tailored contexts combat health threat posed formidable disease effectively.

Mosquitoes are regarded as the most dangerous creatures on earth, spreading deadly pathogens through their bites. Human activities driving range expansions of many mosquito species by unintentionally introducing them beyond native ranges. Despite often dire consequences for human health, a global picture introduction trends and resulting mosquitoes is missing.
