Malaria in China: a discourse-historical perspective

Frontiers in Medicine
The translation, transmission, and re-conceptualization of malaria in late Qing and Republican China exemplifies how knowledge on an ancient disease is reshaped through linguistic and cultural mediation.

Lack of fitness cost associated to CYP9K1‐mediated insecticide resistance in Anopheles funestus, represents a threat to vector control

Pest Management Science, EarlyView.
The 454A‐CYP9K1‐mediated resistance confers fitness advantages regarding pupation and longevity in Anopheles funestus, resulting to a slow susceptibility reversion. By contrast, the 119F‐GSTe2 resistance allele rapidly declines. Abstract BACKGROUND Resistance management is critical to maintain insecticide effectiveness in malaria control, and ...

Long‐term impact of exposure to Royal Guard, a pyriproxyfen‐based bed net, on pyrethroid‐resistant malaria vectors from Cameroon using DNA‐based metabolic resistance markers

Pest Management Science, Volume 81, Issue 4, Page 2165-2180, April 2025.
We used recently detected P450 DNA‐based markers of pyrethroid resistance in both Anopheles funestus and Anopheles gambiae to demonstrate that although pyrethroid‐resistant mosquitoes have higher ability to survive and live longer after exposure to Royal Guard, this net significantly affects their lifespan, blood feeding ability and interestingly ...

Malaria vector density entomological surveillance system evaluation, Zambezia, Mozambique, 2017-2019

Journal of Interventional Epidemiology and Public Health
Introduction: Vector density is the degree of domiciliation of malaria vectors that influence the vectorial capacity of mosquito populations in different regions and at different times.

Illegal Gold Mining in the Brazilian Amazon: Environmental Degradation in Yanomami Indigenous Lands, and Regulatory Failures

Sustainable Development, EarlyView.
ABSTRACT Illegal gold mining has emerged as a major sustainability threat in the Amazon, eroding Indigenous rights, forest integrity, and climate mitigation efforts. This study examines how international market incentives relate to the expansion of illegal mining and associated deforestation within the Yanomami Indigenous Territory (YIT) from 2008 to ...

Salivary gland proteins of the human malaria vector, Anopheles dirus B (Diptera Culicidae) [PDF]

, 2007
Salivary gland proteins of the human malaria vector, Anopheles dirus B were determined and analyzed. The amount of salivary gland proteins in mosquitoes aged between 3--10 days was approximately 1.08 +/- 0.04 microg/female and 0.1 +/- 0.05 microg/male ...

Prostaglandin E2 (PGE2) signaling regulates fluid excretion and uric acid metabolism in the mosquito Anopheles gambiae

Insect Science, EarlyView.
Prostaglandin E2 (PGE2) signaling via its receptor has integral roles in mosquito physiology, mediating fluid excretion, stimulating hindgut contractions, and in modulating uric acid levels. Together, these results uncover previously unrecognized roles of prostaglandin signaling in osmotic balance and metabolic homeostasis in mosquitoes.

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

Integrative 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 ...

Impact of full coverage of population with Long-Lasting Insecticidal Nets (LLINs) on malaria vector density in Gadchiroli district of Maharashtra, India

Journal of Vector Borne Diseases
Background & objectives: Long-lasting insecticidal nets (LLINs) are a major weapon in the fight against malaria. But protection of each family member is not possible with current distribution system with 80% coverage.
