![]() ![]() By doing so, this review may open new doors for research on mosquito-borne diseases. In this article, the current state of knowledge on the different mosquito control strategies in general, and on repellent and mosquitocidal plant-mediated synthesis of nanoparticles in particular, has been reviewed. As a single-step, eco-friendly, and biodegradable method that does not require the use of toxic chemicals, the green synthesis of nanoparticles using active toxic agents from plant extracts available since ancient times exhibits antagonistic responses and broad-spectrum target-specific activities against different species of vector mosquitoes. Adapting the principles of nanobiotechnology to mosquito vector control is one of the current approaches. ![]() Therefore, the development of novel and effective methods of control is urgently needed to manage mosquito vectors. However, these different strategies are facing important and timely challenges that include the rapid spread of highly invasive mosquitoes worldwide, the development of resistance in several mosquito species, and the recent outbreaks of novel arthropod-borne viruses (e.g., Dengue, Rift Valley fever, tick-borne encephalitis, West Nile, yellow fever, etc.). To reduce the transmission of these mosquito-borne diseases in humans, several chemical, biological, mechanical, and pharmaceutical methods of control are used. Mosquitoes act as vectors of pathogens that cause most life-threatening diseases, such as malaria, Dengue, Chikungunya, Yellow fever, Zika, West Nile, Lymphatic filariasis, etc. Our study reports provide potential candidates for the identification of active molecules to be developed for strengthening the biological control of infectious diseases agents transmitted by mosquitoes. The Streptomyces species we isolated seem to be potential new species, and 3/5 (60%) of them exhibited insecticidal activity. nealsonii, which is not a well-known bacterium, had the highest larvicidal effect with 70% of the larval mortality, which is highlighted for the first time. A total of 4/11 (36.36%) of the isolated species exhibited insecticidal activity. Then, we tested their secondary metabolites, which were obtained from the supernatant fraction, and their cell wall and cytoplasmic compounds, which were found in the pellet fraction, in Aedes albopictus larvae, and compared the larval mortality rate with that obtained by using a commercial product. Among bacterial strains isolated from dry sandy soil from Senegal, eleven strains from the Bacillales and Actinomycetales orders were chosen for the entomopathogenic activity experiments. Here, we attempted to identify bacterial species with potential anti-mosquito actions. Currently, the development of new alternative molecules is urgently needed, in order to use them in mosaics or in rotation with already known insecticides for the control of vectors, especially mosquitoes. Biological control has been performed by using formulations of Bacillus sphaericus and Bacillus thuringiensis, but their intensive use has led to the emergence of resistance. Chemical compounds often have devastating side effects, leading to the abandonment of the majority of them. They are transmitted by several vectors, among which the mosquito is the most important. Vector-borne deadly pathogens cause more than 700,000 deaths annually. Microbial metabolites from actinobacteria, bacteria, fungi and viruses. This review paper communicates the insect problem in the transmission ofĭiseases in human, animals, plants and problem of chemical insecticides control of insects using Microbial insecticides are generally pest-specific, readily biodegradable and usually lack toxicity Many viruses that belong to the family Baculoviridae are pathogenic in insects. Fungi are applied directly in the form of spores, mycelia or blastospores or by their Only four Bacillus species namely Bacillus thuringiensis,īacillus popilliae, Bacillus lentimorbus, Bacillus sphaericus have been closely examined as insectĬontrol agents. Insects belong to the family Bacillaceae. Most spore-forming bacteria pathogenic to Than actinobacteria showed the insecticidal activity. Representatives of 18 genera, 28 unidentified aerobic actinobacteria, 70 fungi and 40 bacteria other The isolates included 302 streptomycetes, 502 novel actinobacteria including Metabolites from 942 microbial isolates were screened for insecticidalĪnd properties. Approximately 1500 naturally occurring microorganisms have been identified as potentially
