| Spanish abstract | En México, Bactericera cockerelli es una plaga primaria en solanáceas. En los últimos años, se ha incrementado el uso de insecticidas para disminuir sus altas densidades; sin embargo, el uso irracional de éstos genera problemas de resistencia, mediante el incremento de enzimas. En la zona papera de Coahuila y Nuevo León, se desconocen los mecanismos y niveles enzimáticos involucrados en la resistencia a insecticidas por B. cockerelli, por lo anterior se determinaron los mecanismos enzimáticos de resistencia en 20 poblaciones de B. cockerelli, provenientes de la región papera de Coahuila y Nuevo León. Los resultados mostraron la presencia de todas las enzimas; las β-EST y OX fueron los grupos de enzimas con mayor presencia, por su parte, las GST y ACE no presentaron relevancia como mecanismo detoxificativo |
| English abstract | In Mexico, Bactericera cockerelli is a main plague in solanaceous crops. In recent years, there has been an increase use of insecticides in order to reduce high densities of this plague. Irrational use of these agrochemicals has resulted in insect resistance problems, due to increased production of insecticide detoxifying enzymes esterases (EST), oxidases (OX), glutathione s-transferase (GST) and acetylcholinesterase (ACE). The mechanisms and enzyme levels involved in tolerance to insecticides of B. cockerelli from potato-growing regions in Coahuila and Nuevo Leon remain unknown. Therefore, the enzymatic mechanisms for resistance in 20 B. cockerelli populations from potato-growing regions in Northeastern Mexico were determined. The results revealed the presence of all enzymes, although β-esterases and oxidases were the groups with a greater presence. On the other hand, glutathione s-transferase and acetylcholinesterase showed little relevance as detoxifying mechanisms |
