Quantifying Reductions in Plasmodium falciparum Infectivity to Mosquitos: A Sample Size Calculator to Inform Clinical Trials on Transmission-Reducing Interventions

Frontiers in Immunology, 2022
Malaria transmission depends on the presence of mature Plasmodium transmission stages (gametocytes) that may render blood-feeding Anopheles mosquitos infectious.

HYBRIDIZATION BETWEEN ANOPHELES CRUCIANS AND ANOPHELES BRADLEYI [PDF]

Evolution, 1971
In the southeastern United States there exists the so-called crucians complex which consists of three species of the genus Anopheles: crucians, bradleyi and georgianus. They are morphologically very similar, and may be separated with certainty only as fourth instar larvae.

Advanced Techniques to Control Mosquitoes and their Disease Transmission: A Review

Journal of Pure and Applied Microbiology
Mosquitoes transmit life-threatening diseases to humans. The conventional mosquito control techniques that have been focused on population reduction by the application of insecticides or through source reduction by removing the larval habitat have become

Anopheles gambiae and Anopheles arabiensis population densities and infectivity in Kopere village, Western Kenya

Journal of Infection in Developing Countries, 2012
Introduction: This study was conducted in a sugar belt region of western Kenya interfacing epidemic and endemic malaria transmission. We investigated Anopheles gambiae sensu stricto (ss) and Anopheles arabiensis species compositions and densities, human

Genetic Surveillance Reveals Differential Evolutionary Dynamic of Anopheles gambiae Under Contrasting Insecticidal Tools Used in Malaria Control. [PDF]

Mol Ecol
ABSTRACT Malaria, a febrile disease caused by the Plasmodium parasites and transmitted by mosquitoes, is a leading cause of mortality in children under 5 in endemic countries. The widespread deployment of insecticide‐treated bed nets (ITNs) has significantly reduced malaria transmission, but rising levels of insecticide resistance threaten to halt the ...

Naturally acquired antibodies to gametocyte antigens are associated with reduced transmission of Plasmodium vivax gametocytes to Anopheles arabiensis mosquitoes

Frontiers in Cellular and Infection Microbiology, 2023
Naturally acquired antibodies may reduce the transmission of Plasmodium gametocytes to mosquitoes. Here, we investigated associations between antibody prevalence and P. vivax infectivity to mosquitoes. A total of 368 microscopy confirmed P.

The influence of late-stage pupal irradiation and increased irradiated:un-irradiated male ratio on mating competitiveness of the malaria mosquito Anopheles arabiensis Patton [PDF]

, 2009
Competitiveness of released males in genetic control programmes is of critical importance. In this paper, we explored two scenarios to compensate for the loss of mating competitiveness after pupal stage irradiation in males of the malaria mosquito ...
