- Susceptibility of pepper weevil (anthonomus eugenii cano) (coleoptera: curculionidae) to seven insecticides in rural areas of Baja California Sur, Mexico José L. Martínez Carrillo Rosalía Servín Villegas José. L. García Hernández Armando Tejas Romero M. A. Toapanta Biología México peeper weevil susceptibility Anthonomus eugenii Baja California Sur The susceptibility of the pepper weevil (Anthonomus eugenii), collected from Baja California Sur,Mexico, to seven insecticides was determined. Acontact, residual exposition method was used to obtainthe lethal concentrations fifty (LC50) and the diagnostic concentration (LC95) of organophosphates (OF),carbamates (CA), pyrethroids (PIR), and organochlorine (OC) insecticides used to control pepperweevils from two agricultural areas (Los Planes and Todos Santos) in Southern Baja CaliforniaPeninsula, as well as on a pepper weevil population not exposed to insecticides (PWIF) for two years.The highest LC50´s were obtained for methomyl (CA) and oxamyl (CA), followed by methamidophos(OF), endosulfan (OC), cyfluthrin (PIR) and azinphos-methyl (OF). The lowest LC50´s were observedfor carbaryl (CA). The field population from Todos Santos showed lower susceptibility than thepopulation from Los Planes to insecticides as methomyl, oxamyl, and carbaryl, while with methamidophos, azinphos-methyl, and cyfluthrin, the LC50 showed higher values. The PWIF populationpresented the lowest LC50 values of all three populations tested. However, in most cases, the differencewas not significant in relation to the two field populations, thus the PWIF population needs to be keptfree of insecticides for longer periods to establish a susceptibility baseline for Anthonomus eugenii. 2008 artículo científico 0065-1737 https://www.redalyc.org/articulo.oa?id=57524304 en http://www.redalyc.org/revista.oa?id=575 Acta Zoológica Mexicana (nueva serie) application/pdf Instituto de Ecología, A.C.
