Targeting mosquitoes to target malaria Anopheline transmit the parasite, but insects themselves are prone their own infections. Lovett et al. engineered a specific fungal pathogen of anophelines carry insect-selective toxins. The effectiveness this fungus for controlling was trialed in near-field conditions Burkina Faso setup called MosquitoSphere. Approximately 75% wild insecticide-resistant released into environment became infected with transgenic fungus, causing population collapse within...
Malaria control demands the development of a wide range complementary strategies. We describe properties naturally occurring, non-genetically modified symbiotic bacterium,
Malaria control programs are being jeopardized by the spread of insecticide resistance in mosquito vector populations. It has been estimated that could lead to an additional 120000 deaths per year, and interfere with prospects for sustained or feasibility achieving malaria elimination. Another complication development management strategies is that, addition resistance, behavior evolves a manner diminishes impact LLINs IRS. Mosquitoes may circumvent LLIN IRS through preferential feeding...
Abstract Background Malaria, a disease transmitted by Anopheles mosquitoes, is major public health problem causing millions of deaths worldwide, mostly among children under the age 5 years. Biotechnological interventions targeting parasite-vector interactions have shown that microsporidian symbiont Microsporidia MB has potential to disrupt and block Plasmodium transmission. Methods A prospective cross-sectional survey was conducted in Zinder City (Zinder), Niger, from August September 2022,...

Background: Genetic control tools, such as the sterile insect technique (SIT) and genetically modified mosquitoes (GMMs), require releasing males comparable to their wild counterparts. Ensuring that released do not exhibit higher insecticide resistance is critical. This study assessed phenotypic characteristics susceptibility of key dengue malaria vector species. Methods: Phenotypic deltamethrin (0.05%) was tested in two-to-five-day-old male female Aedes aegypti (Linnaeus, 1762) (Borabora...
Genetically enhanced Metarhizium pingshaense are being developed for malaria vector control in Burkina Faso. However, not much is known about the local prevalence and pathogenicity of this fungus, so we prospected mosquitoes plant roots (a common habitat spp.) entomopathogenic fungi. Our investigations showed that spp. represented between 29–74% fungi isolated from root rhizospheres diverse collection sites. At low spore dosages (1 × 106 conidia/ml), two mosquito-derived M. isolates (Met_S26...
The continued success of malaria control efforts requires the development, study and implementation new technologies that circumvent insecticide resistance. We previously demonstrated fungal pathogens can provide an effective delivery system for mosquitocidal or malariacidal biomolecules. Here we compared genes from arthropod predators encoding insect specific sodium, potassium calcium channel blockers their ability to improve efficacy Metarhizium against wild-caught, insecticide-resistant...
Abstract Dengue represents an increasing public health burden worldwide. In Africa, underreporting and misdiagnosis often mask its true epidemiology, dengue is likely to be both more widespread than reported data suggest in incidence distribution. Wolbachia ‐based control underway Asia the Americas but has not date been deployed Africa. Due genetic heterogeneity of African Aedes aegypti populations complexity host‐symbiont interactions, characterization key parameters ‐carrying mosquitoes...
Abstract Symbiotic and pathogenic microorganisms such as bacteria fungi represent promising alternatives to chemical insecticides respond the rapid increase of insecticide resistance vector‐borne disease outbreaks. This study investigated interaction two strains Wolbachia , w AlbB Au, with natural entomopathogenic from Burkina Faso Metarhizium pingshaense known be lethal against Anopheles mosquitoes. In addition showing potential African Aedes aegypti wild‐type populations, our shows that Au...
Current malaria control strategies have cut down the burden in many endemic areas, however emergence and rapid spread of insecticide drug resistance undermine success these efforts. There is growing concern that eradication will not be achieved without introduction novel tools. One approach has been developed last few years based on house screening to reduce indoor mosquito vector densities consequently decrease transmission. Here trapping were combined one tool populations. The trap does...
Using bacteria to express and deliver anti-parasite molecules in mosquitoes is among the list of genetic tools control malaria. The introduction spread transgenic through wild adult one major challenges this strategy. In prospect future field experiments, an open study with blank (without bacteria) attractive sugar bait (ASB) was performed under assumption that would be all fed mosquitoes. Two types ASB stations were developed, clay pots (CP) placed at mosquito resting sites window entry...
Vector control tools are urgently needed to malaria transmission in Africa. A native strain of Chromobacterium sp. from Burkina Faso was recently isolated and preliminarily named anophelis nov. IRSSSOUMB001. In bioassays, this bacterium showed a promising virulence against adult mosquitoes reduces their blood feeding propensity fecundity. The current study assessed the entomopathogenic effects C. IRSSSOUMB001 on larval stages mosquitoes, as well its impacts infected reproductive capacity...
Transgenic Metarhizium pingshaense expressing the spider neurotoxin Hybrid (Met-Hybrid) kill mosquitoes faster and at lower spore doses than wild-type strains. In this study, we demonstrate that approach dovetails with cornerstone of current malaria control: pyrethroid-insecticides, which are control. We used World Health Organization (WHO) tubes, to compare impact on insecticide resistance Met-Hybrid red fluorescent M. (Met-RFP), as a proxy for fungus. Insecticides killed less 20% Anopheles...
Abstract Background This is now a concern that malaria eradication will not be achieved without the introduction of novel control tools. Microbiological might able to make greater contribution vector in future. The interactions between bacteria and mosquito microbiota really promising from disease perspective. Here, impact Chromobacterium violaceum infections, isolated both larvae adult wild-caught Anopheles gambiae sensu lato mosquitoes Burkina Faso, was evaluated on survival, blood feeding...
Vector mosquito control is an integral part of malaria control. The global emergence insecticide resistance in malaria-transmitting Anophelines has become impediment and created urgent need for novel approaches. Here, we show that a biopesticide derived from the soil-dwelling bacterium Chromobacterium sp. Panama ( Csp_P ) kills insecticide-resistant Anopheles mosquitoes, regardless their mechanisms. In addition, sublethal dose acts as synergist to now used chemical insecticides across...
