Insect I‐Type Lysozymes Function as Antiviral Proteases by Forming Biomolecular Condensates

Advanced Science, Volume 13, Issue 1, 5 January 2026.
Upon rice viral infection, the insect vector activates the Toll–MyD88–Dorsal signaling cascade, inducing i‐type lysozyme (Lyz‐I1) expression. Lyz‐I1 functions as an antiviral protease through its conserved catalytic dyad Glu/Asp (E/D), mediating cleavage of viral proteins at specific Lys (K) residues.

Contribution of Anopheles gambiae sensu lato mosquitoes to malaria transmission during the dry season in Djoumouna and Ntoula villages in the Republic of the Congo

Parasites & Vectors
Background Mosquitoes belonging to the Anopheles gambiae sensu lato complex play a major role in malaria transmission across Africa. This study assessed the relative importance of members of An. gambiae s.l.

Emergence of knock-down resistance in the Anopheles gambiae complex in the Upper River Region, The Gambia, and its relationship with malaria infection in children

Malaria Journal, 2018
BackgroundInsecticide resistance threatens malaria control in sub-Saharan Africa. Knockdown resistance to pyrethroids and organochlorines in Anopheles gambiae sensu lato (s.l.) is commonly caused by mutations in the gene encoding a voltage-gated sodium ...

The physicochemical and environmental factors affecting the distribution of Anopheles merus along the Kenyan coast

Parasites & Vectors, 2015
Background Members of the Anopheles gambiae complex are the main transmitters of malaria. Anopheles merus is a member of the complex found along the Kenyan coast because it breeds in saline waters.

Investigating insecticide resistance and knock-down resistance (kdr) mutation in Dielmo, Senegal, an area under long lasting insecticidal-treated nets universal coverage for 10 years

Malaria Journal, 2018
Background The use of insecticides, through indoor residual spraying and long-lasting insecticide-treated nets (LLINs), is essential to control malaria vectors.

Responses of Anopheles gambiae complex mosquitoes to the use of untreated bednets in The Gambia

Medical and Veterinary Entomology, 1989
ABSTRACT. Population dynamics of the Anopheles gambiae complex of malaria vector mosquitoes were studied in four small hamlets in The Gambia. Bednets were used to reduce man/vector contact in two of the hamlets. High densities of An. gambiae, sensu lato,

Presence of Plasmodium vivax in Anopheles gambiae and absence in other malaria vectors in Cove-Zagnanando-Ouinhi health zone in southern Benin, West Africa

Malaria Journal
Background Malaria remains a major public health problem in sub-Saharan Africa, particularly in Benin. The present study aims to evaluate the different Plasmodium species transmitted by malaria vectors in the communes of Cove, Zagnanado and Ouinhi ...

Malaria vectors and transmission dynamics in coastal south-western Cameroon

Malaria Journal, 2007
Background Malaria is a major public health problem in Cameroon. Unlike in the southern forested areas where the epidemiology of malaria has been better studied prior to the implementation of control activities, little is known about the distribution and

ANOPHELES GAMBIAE, A COMPLEX OF SPECIES.

Bulletin of the World Health Organization, 1996
The author reports on some 200 laboratory crossings of 36 strains of Anopheles gambiae from many different parts of Africa which show the existence of five mating-types in what was until recently considered a single species. Three of these mating-types are freshwater forms and have been provisionally called A, B and C. Two are saltwater forms: A. melas,
