Confirmation of the presence of Anopheles stephensi among internally displaced people’s camps and host communities in Aden city, Yemen

Malaria Journal, 2023
Background Declines in global malaria cases and deaths since the millennium are currently challenged by multiple factors including funding limitations, limits of, and resistance to vector control tools, and also recent spread of the invasive vector ...

Temperature impacts the environmental suitability for malaria transmission by Anopheles gambiae and Anopheles stephensi

Ecology, 2022
Extrinsic environmental factors influence the spatiotemporal dynamics of many organisms, including insects that transmit the pathogens responsible for vector-borne diseases (VBDs).

Gene copy number and function of the APL1 immune factor changed during Anopheles evolution

Parasites & Vectors, 2020
Background The recent reference genome assembly and annotation of the Asian malaria vector Anopheles stephensi detected only one gene encoding the leucine-rich repeat immune factor APL1, while in the Anopheles gambiae and sibling Anopheles coluzzii, APL1

Effect of temperature on fecundity and lifetime of Anopheles stephensi

Di-san junyi daxue xuebao, 2020
Objective To determine the effect of ambient temperature on fecundity of Anopheles stephensi and investigate its molecular mechanisms. Methods After Anopheles stephensi were divided into 5 groups, they were maintained in a mosquito cage at environment ...

The impact of climatic variables on the population dynamics of the main malaria vector, Anopheles stephensi Liston (Diptera: Culicidae), in southern Iran

Asian Pacific Journal of Tropical Medicine, 2020
Objective: To determine the significance of temperature, rainfall and humidity in the seasonal abundance of Anopheles stephensi in southern Iran. Methods: Data on the monthly abundance of Anopheles stephensi larvae and adults were gathered from earlier ...

Population genomic analyses reveal population structure and major hubs of invasive Anopheles stephensi in the Horn of Africa

Molecular Ecology, 2023
Anopheles stephensi invasion in the Horn of Africa (HoA) poses a substantial risk of increased malaria disease burden in the region. An understanding of the history of introduction(s), establishment(s) and potential A.

PCR cloning of a histone H1 gene from Anopheles stephensi mosquito cells: comparison of the protein sequence with histone H1-like, C-terminal extensions on mosquito ribosomal protein S6

BMC Genomics, 2005
Background In Aedes and Anopheles mosquitoes, ribosomal protein RPS6 has an unusual C-terminal extension that resembles histone H1 proteins. To explore homology between a mosquito H1 histone and the RPS6 tail, we took advantage of the Anopheles gambiae ...

Citizen Science as an Approach for Responding to the Threat of Anopheles stephensi in Africa

Citizen Science: Theory and Practice, 2023
Even as novel technologies emerge and medicines advance, pathogen-transmitting mosquitoes pose a deadly and accelerating public health threat. Detecting and mitigating the spread of Anopheles stephensi in Africa is now critical to the fight against ...

Vector competence of Anopheles stephensi for O’nyong-nyong virus: a risk for global virus spread

Parasites & Vectors, 2023
Background O’nyong-nyong virus (ONNV) is a mosquito-borne alphavirus causing sporadic outbreaks of febrile illness with rash and polyarthralgia. Up to now, ONNV has been restricted to Africa and only two competent vectors have been found, Anopheles ...
