ORTIZ GARCIA, Karla Paulina et al. Agroecological management of Macrodactylus nigripes (Coleoptera: Melolonthidae) in corn. Rev. Mex. Cienc. Agríc [online]. 2023, vol.14, n.1, pp.13-24.  Epub 19-Jun-2023. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v14i1.2859.

Macrodactylus nigripes (Bates) is a pest that attacks corn crops, causing economic losses in production. In order to find agroecological alternatives for its management, the objective was to evaluate the effect of the application of Argemone mexicana L., Ricinus communis L, Beauveria bassiana (Bals) Vuill and Metharrizium anisoplae (Metschnikoff) Sorokin, as well as the collection of M. nigripes with a beating net in corn crops. The experiment was conducted under a completely randomized block design with four repetitions, where the five control methods were tested and compared with the control treatment (water). R. communis and A. mexicana significantly decreased plant infestation by M. nigripes, increasing production by 36% and 30%, respectively. These results show that both treatments alternated with zote soap can be a good alternative for the management of this pest species.
