An Overview of Different Control Methods of Invasive Aedes Aegypti and Aedes Albopictus
Abstract
Background and purpose: Aedes mosquitoes, especially Aedes aegypti and A. albopictus, due to their special biological and ecological characteristics, have high adaptability and establishment power in different weather conditions, including Iran, and for this reason, they are called invasive mosquitoes. These mosquitoes, which are known as a serious problem for human health, are very important in terms of transmission of very important arboviral diseases such as dengue fever, chikungunya, Zika virus, and yellow fever. Considering the importance of these diseases on the health system and human health, as well as numerous reports of the spread of arboviral diseases through Aedes mosquitoes in different countries, various programs have been proposed to control Aedes mosquitoes. As a result, introducing suitable methods to control Aedes mosquitoes can play a significant role in reducing the transmission of these diseases and maintaining human health. Therefore, in this review, we evaluate the use of each of the Aedes mosquito control methods. Materials and methods: This article is a narrative review of the introduction and effectiveness of different methods of controlling Aedes mosquitoes. Collecting information about control methods of A. aegypti and A. albopictus has been compiled without time and language restrictions from international scientific databases including Pub Med, Web of Science, Google Scholar, (ScienceDirect, Scopus, Elsevier, Lilacs) and Internal databases including, Scientific Information Database(SID), Iranian Medical Library(MedLib), Magiran, Civilica. The information collected based on the performance of each of the mentioned methods was extracted, categorized, analyzed, and used in compiling this article. Finally, out of a total of 10202 extracted articles, 123 articles were used in this research considering the inclusion and exclusion criteria. Results: In general, the goals related to the use of different methods of controlling Aedes mosquitoes are different depending on the country, epidemiological conditions, resources, and local priorities. But overall, disease prevention, reduction of mosquito population, stopping of disease transmission, prevention of mosquito establishment, disease spread, reduction of nuisances and finally identification of new invasive species are prioritized. The most appropriate methods of controlling Aedes are divided into five categories: 1. Environmental methods that include reducing the habitats and growth resources of mosquitoes 2. Chemical methods that are based on the use of various insecticides chemicals and insect growth regulators 3. Mechanical methods that include the use of various traps 4. Biological methods that include the use of natural enemies 5. Genetic methods include genetic engineering and mosquito sterilization techniques. It should be noted that each of these methods can play a significant role in the establishment of Aedes mosquitoes and the spread of arboviral diseases, and as a result, reducing the number of cases of infection and death in the health system. Conclusion: Considering the introduction of different control methods for A. aegypti and A. albopictus and the priority of each of the control methods presented; it is important to mention that the method of controlling Aedes depends a lot on the environmental conditions of the region, the stage of mosquito establishment, the population phase of mosquitoes and diseases caused by it. Therefore implementation of Aedes mosquito control programs through integrated vector management strategy is recommended, which requires the effective collaboration and coordination of national and local authorities and the general public for cost-effective control and lasting effects.
