LEYVA, Maureen et al. Insecticidal activity plants: A natural alternative against mosquitoes. Current status of the topic in the America´s region. Rev. biomédica [online]. 2017, vol.28, n.3, pp.139-181. ISSN 2007-8447.  https://doi.org/10.32776/revbiomed.v28i3.571.

The following paper aims to gather the existing information regarding the evaluation of the insecticidal activity of plants against mosquitoes made in the region of the Americas in the last twenty years. Pubmed Central, SCielo regional and BioOne were used and search engines such as Google and Bing were used. As an inclusion criterion, the categories were introduced: larvicidal, adulticidal-repellent, ovicidal activity and inhibitor of the development of essential oils and extracts of plants under conditions of Laboratory in the area of the Americas in a period from 1995-2015. The most studied mosquito species was Ae aegypti followed by Cx. quinquefascitus, Ae. albopictus and Cx tarsalis, Cx. pipiens, An. albimanus. The country at the forefront in studies on this subject is Brazil followed by Cuba Mexico, United States. The United States stands out by evaluating commercially registered herbal products with repellent activity. The larvicidal activity was evaluated in 239 plants. 64% of the reviewed articles study this type of activity with essential oils. The repellency is the most studied section after the larvicidal activity, among which the evaluation of commercial formulations with natural active principles. With little representation, there are studies on ovicidal and developmental inhibitory activity. More than 85 plants have been evaluated in the form of extracts and the most evaluated extract has been ethanolic followed by methanolic and aqueous.

Keywords : larvicidal; adulticidal repellence activity; essential oils; mosquitoes.
