Gene drive mosquitoes are a novel approach to vector control being developed to help tackle malaria. A gene drive increases the frequency of a desired gene and its phenotypic effect into a mosquito population through reproduction in relatively few generations . Combining gene drive with the precision of gene editing, scientists are able to modify the Anopheles mosquito genome and push modifications through natural vector populations.
Plasmodium falciparum parasite is the most deadly species of human malaria, and the development of an effective vaccine that prevents P. falciparum infection and transmission is a key target for malarial elimination and eradication programmes. P. falciparum cell-traversal protein for ookinetes and sporozoites (PfCelTOS) is an advanced vaccine candidate. A comparative study was performed to characterize the immune responses in BALB/c mouse immunized with Escherichia coli-expressed recombinant PfCelTOS (rPfCelTOS) in toll-like receptor (TLR)-based adjuvants, CpG and Poly I:C alone or in combination (CpG + Poly I:C), followed by the assessment of transmission-reducing activity (TRA) of anti-rPfCelTOS antibodies obtained from different vaccine groups in Anopheles stephensi.
Anopheline’ is both an adjective (‘anopheline mosquito’) and a noun. Don’t use an upper case ‘A’, except at the beginning of a sentence; and do not italicize the word as if it is a Latinized genus name.
The continual monitoring of these vectors during the late operational phase may be useful in order to understand how anophelines will behave in this area.
Anopheles cracens has been incriminated as the vector of human knowlesi malaria in peninsular Malaysia.
We initiated a longitudinal mosquito surveillance study with carbon dioxide-baited Heavy Duty Encephalitis Vector Survey traps at four sampling sites to analyse the spatio-temporal pattern of the (i) mosquito species composition and diversity, (ii) functional groups of mosquitoes (oviposition sites, overwintering stage, and number of generations), and (iii) the occurrence of potential West Nile virus (WNV) vectors.
The vector composition in Papua, Indonesia is consistent with certain northern areas of PNG, but the behaviours of anophelines sampled in this region, such as early and indoor human biting of An. farauti 4, may enable them to act as major vectors of malaria.
This study showed a high variation in malaria incidence and Anopheles between kebeles.
The aim of this study was to analyse esterase activity levels at different ages during the life-span of adult Anopheles funestus Giles in order to better understand the complex biological processes in this species.
The study shows evidence of considerable heterogeneity in both insecticide susceptibility and the level of bio-efficacy of commonly available types of LLINs against wild A. funestus and A. gambiae from Balama, Mocuba and Milange districts, located in north and centre of Mozambique.
