Applications of nanomaterials in mosquito vector control: A review

Abstract

The periodic outbreak of mosquito-borne diseases like dengue fever, zika fever, and yellow fever all over the world highlights the need for effective mosquito control methods targeting the biological system. Due to the lack of therapeutic measures, preventive treatments or vaccines against pathogens, insecticide resistance eventually lead the research focus towards novel technological applications in mosquito management. Nanomaterials with ovicidal, larvicidal, adulticidal, and repellent properties for controlling mosquito vectors are under research. A literature search was carried out for advancements in nanomaterials, insecticides, and mosquito control in PubMed/MEDLINE, Scopus, Google Scholar, ScienceDirect, and Web of Science. This paper aims to provide insights into various nanomaterials relevant to mosquito-borne diseases, in vivo and in vitro toxicity evaluation against mosquito species, mode of action, effect on non-target organisms, and ecological risks. Organic and inorganic materials that provide controlled release, target delivery, less dosage, prolonged efficacy, a reduction in the use of organic solvents and emulsifiers, and minimum pollution to the environment have already been explored. Indeed, further research on the ecological risk and economic feasibility of nanomaterials in mosquitocidal applications should be done prior to commercialization.
