ESQUIVEL-RIVERA, J.A. et al. Vegetable extracts evaluation as an control alternative For two stored corn pests, Sitophilus zeamais (Motschulsky) and Prostephanus truncatus (Horn). Revista bio ciencias [online]. 2022, vol.9, e1282. Epub 12-Abr-2024. ISSN 2007-3380. https://doi.org/10.15741/revbio.09.e1282.
Weed plants associated with the corn agroecosystem were collected in three municipalities of Aguascalientes with the aim of evaluating, under laboratory conditions, the effect of ethanolic and infusion extracts for the control of Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae) and Prostephanus truncatus (Horn) (Coleoptera: Bostrichidae) in stored corn grains. Through olfactometric tests, it was determined that infusions of Bromus catharticus Vahl. (80 %) and Verbena bipinnatifida Nutt. (40 %) were those that generated the greatest repellency. In ethanolic extracts, the highest repellency occurred with Parthenium hysterophorus L. (80 %) followed by Pennisetum clandestinum Hochst. ex Chiov. (75 %) and Nicotiana glauca Graham. (70 %). In a second toxicity test with the extracts with the highest repellency, the highest mortality on S. seamaiz was produced by the infusion of Bromus cathartiucus Val. (57.5 %) followed by the ethanolic extract of Nicotiana glauca (Graham) (47.5 %). In the case of P. truncatus also the infusion extract of B. catharticus produced 70 % mortality and 62.5 % with the ethanolic extract of Reseda luteola L. According to these results, extracts of these plants could be used for the control of S. zeamais and P. truncatus in an ecological pest management program of stored corn.
