Special attention was given to essential oils and their active constituents, as well as current advancements in formulation technologies, stability issues, and standardization practices.</p><p><strong>Results: </strong>The utilization of conventional chemical insecticides for controlling mosquitoes has resulted in the development of biological resistance and has detrimental environmental impacts. Consequently, researchers have made significant efforts in recent years to develop sustainable and economical alternatives, with a particular focus on botanical mosquito-repellent compounds. This has led to a marked increase in interest in the use of plant derieved products as mosquito repellents. Limonene, citronellol, eucalyptol, geraniol, eugenol, carvacrol, and citronellal are the primary essential oil components extracted from plants that exhibit mosquito repellent activity. Owing to their complex chemical structures, mosquitoes are unable to develop resistance to these molecules.</p><p><strong>Conclusion: </strong>Plant-based mosquito repellents represent a promising and sustainable alternative to synthetic repellents. However, challenges such as variability in composition, lack of standardization, stability issues, and limited mechanistic understanding hinder their widespread adoption. Molecular and cellular mechanistic studies may increase product safety and efficacy by identifying specific targets and detoxification pathways.</p>","PeriodicalId":6932,"journal":{"name":"Acta Parasitologica","volume":"70 3","pages":"117"},"PeriodicalIF":1.2,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144155410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
