“…The use of H. riparia leaves that grow predominantly in areas cultivated and controlled by man for the production of potential larvicides of plant origin has several advantages, including their easy achievement, cultivation, and little economic investment for their maintenance, a trend observed in South Asia [26] . Additionally, plants, in general, are a rich source of alternative (ecologically friendly) agents for the control of disease-vectoring mosquitoes since they have bioactive chemicals that act against a limited number of species, including target species [27] . A recent literature review [28] shows that compounds derived from plants such as tannins, quinones, flavonoids, sterols, coumarins and alkaloids are widely used as potential larvicides, secondary metabolites present in the species evaluated.…”

Plant extracts and secondary metabolites extracted from plants can produce natural pesticides. Compared to synthetic insecticides, they degrade quickly and threaten the environment and public health less. It was feasible to discover the formation of the important secondary metabolites, phenols, flavonoids, and alkaloids by the Homonoia riparia leaf extract as the investigation progressed. Because phenolic chemicals are renowned for their antioxidant activity, they have a lot of interest. At low doses, the larvicidal activity of Homonoia riparia leaf extract implies that it could be utilized as a domestic larvicide to restrict the spread of the mosquito vector Aedes aegypti. Following the WHO guidelines, a dose-response bioassay was done on Aedes aegypti larvae collected from the municipality of Guntur rural areas. After 48 hours, the extracts of Homonoia riparia (692.6%±125.89) required less concentration to kill 95% of the larvae. Ethanolic extract (EE) obtained from Homonoia riparia leaves, and their effect on Aedes aegypti was evaluated at concentrations of 40, 60, 80, 85, and 95% for EE, in a completely randomized design with a 2x5 factorial arrangement. There were also substantial differences (p<0.01) across the concentrations tested, yielding a 95% death rate at 60%. At high concentrations, the secondary metabolites in the EE were effective, causing acceptable death values in Aedes aegypti, recommending its usage as a preventive control.

“…La utilización de especies arvenses (especies que crecen de forma predominante en zonas cultivadas y/o controladas por el hombre) para la elaboración de potenciales larvicidas de origen vegetal presenta varias ventajas, entre estas su fácil consecución, cultivo y poca inversión económica para su mantenimiento, una tendencia observada en el Sur de Asia (Yadav et al 2015). Adicionalmente, las plantas en general son una fuente rica de agentes alternativos (ecológicamente amigables) para el control de mosquitos vectores de enfermedades, dado que poseen productos químicos bioactivos que actúan en contra de un número limitado de especies, incluyendo las especies diana (Govindarajan 2016).…”

ResumenEl dengue, chikunguña y Zika, todas transmitidas por Aedes aegypti, son enfermedades que afectan ampliamente la población mundial. La evaluación de extractos vegetales permite el establecimiento de productos efi cientes para el control de éste mosquito. Este trabajo evaluó la actividad larvicida en A. aegypti de 23 especies de la familia Asteraceae, y su composición fi toquímica preliminar. El material vegetal utilizado se recolectó en el Departamento del Quindío, Colombia. Con este material se prepararon los extractos vegetales etanólicos utilizados en la caracterización fi toquímica y en los bioensayos. Para cada extracto se realizó un bioensayo dosis-respuesta con larvas provenientes del municipio de Armenia (Quindío, Colombia) siguiendo el protocolo de la OMS. Estos indican que, después de 48 h, los extractos de Jaegeria hirta (694,8% ± 149,9), Austroeupatorium inulaefolium (753,3% ± 198,8) y Heliopsis oppsitifolia (764,4% ± 170,0) requieren menor concentración para matar el 95% de las larvas. Adicionalmente, se construyó un modelo matemático que describe el comportamiento de las poblaciones, con el fi n de evaluar diferentes estrategias de control con los extractos; las simulaciones obtenidas a partir de la solución numérica del sistema permiten concluir que la aplicación de extractos de estas plantas constituye una herramienta viable para el control de A. aegypti. Por su parte, la marcha fi toquímica preliminar de las 23 especies muestra la presencia de taninos, quinonas, fl avonoides, esteroles, cumarinas y alcaloides. Se concluye que J. hirta, A. inulaefoliu y H. oppsitifolia ameritan ser estudiadas en profundidad, dado su potencial larvicida para el control de A. aegypti.

This work evaluated the larvicidal activity of 23 species of the family Asteraceae, and its preliminary phytochemical composition, to control populations of A. aegypti. The vegetable material was collected in the department of Quindío, Colombia. We prepared the plant extracts used in the phytochemical characterization and bioassays with the material collected. For each extract, a dose-response bioassay was performed with larvae from the municipality of Armenia (Quindío, Colombia) following the WHO protocol.

Additionally, a mathematical model that describes the behavior of the mosquito populations was constructed, in order to evaluate different control strategies using the extracts; the simulations obtained from the numerical solution of the system allow us to conclude that the application of extracts from these plants constitutes a viable tool for A...
