Emergence of the invasive malaria vector Anopheles stephensi in Khartoum State, Central Sudan

Parasites & Vectors, 2021
The emergence of the Asian invasive malaria vector, Anopheles stephensi , has been identified in Khartoum, the capital city of Sudan. This is the first report that confirms the geographical expansion of this urban mosquito into Central Sudan. We urgently

Anopheles stephensi: a guest to watch in urban Africa

Tropical Diseases, Travel Medicine and Vaccines, 2022
AbstractMalaria vector control programs in Sub-Saharan Africa have invested many efforts and resources in the control of eight-sibling species of Anopheles gambiae complex and An. funestus group. The behaviour of sibling species of these vectors is well known and used for implementing the current intervention tools. The reports of An.

Possible potential spread of Anopheles stephensi, the Asian malaria vector

BMC Infectious Diseases
Background Anopheles stephensi is native to Southeast Asia and the Arabian Peninsula and has emerged as an effective and invasive malaria vector. Since invasion was reported in Djibouti in 2012, the global invasion range of An.

Malaria mosquito antimicrobial defence requires immunity and detoxification gene regulation by Lola

Insect Molecular Biology, EarlyView.
Malaria mosquito antimicrobial defence requires upregulation of lola. Attenuation of lola in the midgut of Anopheles albimanus mosquitoes inhibits the upregulation of immunity genes induced by challenge. Putative target genes of the Lola transcription factor were revealed by lola attenuation, including Cecropin‐C, Draper, PPAF2, Clip‐domain serine ...

Preimaginal development of Aedes aegypti L. (Diptera: Culicidae) in brackish water gives rise to adult mosquitoes with thicker cuticles and greater insecticide resistance

Medical and Veterinary Entomology, EarlyView.
The principal arboviral vector Aedes aegypti can develop in coastal brackish water field habitats (0.5–15 g/L salt) with larvae possessing thicker cuticles and greater resistance to the larvicide Temephos. Females emerging from brackish water‐developing preimaginal stages are now shown to have thicker and remodelled leg and abdominal cuticles and ...

Anopheline bionomics, insecticide resistance and transnational dispersion in the context of controlling a possible recurrence of malaria transmission in Jaffna city in northern Sri Lanka

Parasites & Vectors, 2020
Background Malaria was eliminated from Sri Lanka in 2013. However, the influx of infected travelers and the presence of potent anopheline vectors can re-initiate transmission in Jaffna city, which is separated by a narrow strait from the malaria-endemic ...

Gene drive-based population suppression in the malaria vector Anopheles stephensi

bioRxiv
Gene drives are alleles that can bias the inheritance of specific traits in target populations for the purpose of modification or suppression. Here, we constructed a homing suppression drive in the major urban malaria vector Anopheles stephensi targeting

A new malaria vector in Africa: Predicting the expansion range of Anopheles stephensi and identifying the urban populations at risk

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance In 2012, an unusual outbreak of malaria occurred in Djibouti City followed by increasingly severe annual outbreaks. Investigations revealed the presence of an Asian mosquito species; Anopheles stephensi, which thrives in urban environments ...

A multiplex assay to detect mosquito species, bloodmeal host source and Plasmodium in malaria vectors using Nanopore amplicon sequencing

Medical and Veterinary Entomology, Volume 40, Issue 3, Page 465-477, September 2026.
Insectary‐reared mosquitoes were simultaneously assessed for species identification, bloodmeal source analysis and Plasmodium detection, using a single multiplexed sequencing run on the MinION sequencing platform. The method was applied to 150 insectary‐reared mosquitoes, representing nine species blood‐fed with five vertebrate hosts and 40 samples for

Susceptibility of wild and colonized Anopheles stephensi to Plasmodium vivax infection

Malaria Journal, 2018
Background As much as 80% of global Plasmodium vivax infections occur in South Asia and there is a shortage of direct studies on infectivity of P. vivax in Anopheles stephensi, the most common urban mosquito carrying human malaria.
