Evaluation of synthetic repellents on mosquito nets in experimental huts against insecticide-resistant Anopheles gambiae and Culex quinquefasciatus mosquitoes.

open access: yes, 2006
Owing to the development of pyrethroid resistance in Anopheles gambiae, there is a need to develop chemical alternatives for use on mosquito nets. Synthetic insect repellents are widely used for personal protection as skin or clothing applications.

Maltase 1 regulates DENV2 infection and life history in Aedes aegypti

open access: yesInsect Science, EarlyView.
Our study employed CRISPR/Cas9 to generate a MAL1 knockout strain of Aedes aegypti, demonstrating that the absence of MAL1 significantly suppresses DENV2 replication in the midgut and impairs viral transmission. The mutation also altered life‐history (hatching/pupation/emerging rates and sex‐specific survival), identifying MAL1 as a novel target for ...

Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Effects of Vector Density on Blood Parasite Spread and Health Consequences for Avian Hosts: An Experimental Epidemiology Blueprint

open access: yesIntegrative Zoology, EarlyView.
In an experimental epidemiology setup, groups of pigeons were exposed to different numbers of infective malaria vectors. Vector number explained the speed of transmission, the final prevalence, and changes in host behavior. ABSTRACT Vector density plays a critical role in the transmission dynamics of vector‐borne diseases and thus in their health and ...

Unraveling Occurrence Patterns and Diversity of Avian Malaria Parasites in Iberian Obligate and Facultative Scavenger Birds

open access: yesIntegrative Zoology, EarlyView.
Low overall haemosporidian occurrence (3.4%; 13/383). Unexpected high lineage diversity (10 new host–parasite interactions). Novel Leucocytozoon lineage (GYPBAR01) in all European vultures except the griffon vulture. Plasmodium relictum (lineage SGS1) in adult red kites.

Urbanization and Vector Species Shape Avian Malaria Prevalence in Mosquitoes

open access: yesIntegrative Zoology, EarlyView.
Avian malaria prevalence was assessed in two mosquito species across urban and peri‐urban habitats. No infections were detected in either species in urban areas, while a 2.53% prevalence was found in the native Culex pipiens from peri‐urban sites, highlighting the influence of urbanization on parasite transmission dynamics.

Imperative for a health‐centred focus on climate change in radiology

open access: yesJournal of Medical Imaging and Radiation Oncology, EarlyView.
Summary Climate change negatively impacts individual and population‐level health through multiple pathways, including poor air quality, extreme heat and changes in infectious disease. These health effects will lead to higher health system and medical imaging utilisation.

Achieving high coverage of larval-stage mosquito surveillance: challenges for a community-based mosquito control programme in urban Dar es Salaam, Tanzania [PDF]

open access: yes, 2009
Background: Preventing malaria by controlling mosquitoes in their larval stages requires regular sensitive monitoring of vector populations and intervention coverage.

Agrarian counterpoint

open access: yesAmerican Ethnologist, EarlyView.
Abstract In Colombia's northeastern borderlands, agrarian economies shape how disease risk and stigma are understood and managed. As shown in ethnographic fieldwork in and around the Catatumbo region, cutaneous leishmaniasis—a sandfly‐transmitted disease that produces chronic skin lesions—appears in two radically different guises across adjacent ...

No detectable fitness cost of infection by cell-fusing agent virus in Aedes aegypti mosquitoes

open access: yesRoyal Society Open Science
Aedes mosquitoes are well-known vectors of arthropod-borne viruses (arboviruses). Mosquitoes are more frequently infected with insect-specific viruses (ISVs) that cannot infect vertebrates.
