Anopheles stephensi is an urban malaria vector native in some Asian countries and recently emerged in Africa as an invasive vector competent in transmitting Plasmodium falciparum and P. vivax. The coexistence of An. stephensi and Aedes arboviral vectors offers an optimal opportunity for successful integrated vector management with limited resources.

Preventing local transmission of malaria from imported cases is crucial for achieving and maintaining malaria elimination. This study aimed to investigate the epidemiological characteristics of imported malaria cases and assess the distribution of malaria vectors in Qatar. Data from January 2016 to December 2022 on imported malaria, including demographic and epidemiological characteristics, travel-related information, and diagnostic results, were collected and analysed using descriptive statistics.

Background And Objectives: Salivary glands proteins but not glycoconjugates have been previously studied in mosquito vectors of human diseases. Glycoconjugates from salivary gland-derived proteins from human-feeding tick vectors can elicit hypersensitivity reactions which may also occur with mosquito bites. Protein glycoconjugate in salivary glands of the principal arboviral vector Aedes aegypti and the rapidly spreading malaria vector Anopheles stephensi were therefore investigated.

Background: The swift expansion of the invasive malaria vector throughout Africa presents a major challenge to malaria control initiatives. Unlike the native African vectors, thrives in urban settings and has developed resistance to multiple classes of insecticides, including pyrethroids, organophosphates, and carbamates.
Methods: Insecticide susceptibility tests were performed on field-collected mosquitoes from Awash Sebac Kilo, Ethiopia, to assess insecticide resistance levels.

The emergence of parasites partially resistant to artemisinins (ART-R) poses a significant threat to recent gains in malaria control. ART-R has been associated with PfKelch13 (K13) mutations, which differ in fitness costs. This study investigates the gametocyte production and transmission fitness of African and Asian isolates with different K13 genotypes across multiple mosquito species.

The peritrophic matrix (PM) acts as a physical barrier that influences the vector competence of mosquitoes. We have previously shown that gut microbiota promotes PM formation in Anopheles stephensi, although the underlying mechanisms remain unclear. In this study, we identify that the cell wall components of gut commensal bacteria contribute to PM formation.
