Anopheles stephensi in Africa requires a more integrated response

Malaria Journal, 2022
There are increasing reports of the Asian malaria mosquito, Anopheles stephensi invading and spreading in Eastern Africa. We discuss the importance of these invasions in the context of broader challenges facing malaria control in Africa and argue against

Characterization of midgut microbiome of Anopheles stephensi Liston

Journal of Vector Borne Diseases, 2021
Background & objectives: Anopheles stephensi is an important vector of malaria in South East Asia. The abundance and diversity of gut microbiota in the disease vectors affect their development, digestion, metabolism and immunity. The immatures of An.

An update on the distribution, bionomics, and insecticide susceptibility of Anopheles stephensi in Ethiopia, 2018–2020

Malaria Journal, 2021
Anopheles stephensi, an invasive malaria vector, was first detected in Africa nearly 10 years ago. After the initial finding in Djibouti, it has subsequently been found in Ethiopia, Sudan and Somalia.

Identification of a biological form in the Anopheles stephensi laboratory colony using the odorant-binding protein 1 intron I sequence.

PLoS ONE, 2022
BackgroundAnopheles stephensi Listen (1901) is a major vector of malaria in Asia and has recently been found in some regions of Africa. The An. stepehnsi species complex is suspected to have three sibling species: type, intermediate, and mysorensis, each

Metabolic pathways inAnopheles stephensimitochondria [PDF]

Biochemical Journal, 2008
No studies have been performed on the mitochondria of malaria vector mosquitoes. This information would be valuable in understanding mosquito aging and detoxification of insecticides, two parameters that have a significant impact on malaria parasite transmission in endemic regions.

Odorant Binding Proteins (OBPs) and Odorant Receptors (ORs) of Anopheles stephensi: Identification and comparative insights.

PLoS ONE, 2022
Anopheles stephensi is an important vector of malaria in the South Asia, the Middle East, and Eastern Africa. The olfactory system of An. stephensi plays an important role in host-seeking, oviposition, and feeding.

Laser induced mortality of Anopheles stephensi mosquitoes [PDF]

Scientific Reports, 2016
AbstractSmall, flying insects continue to pose great risks to both human health and agricultural production throughout the world, so there remains a compelling need to develop new vector and pest control approaches. Here, we examined the use of short (<25 ms) laser pulses to kill or disable anesthetized femaleAnopheles stephensimosquitoes, which ...

Mapping current and future thermal limits to suitability for malaria transmission by the invasive mosquito Anopheles stephensi

bioRxiv, 2022
Background Anopheles stephensi is a malaria-transmitting mosquito that has recently expanded from its primary range in Asia and the Middle East, to locations in Africa. This species is a competent vector of both Plasmodium falciparum and Plasmodium vivax
