          Abstract

          El objetivo de esta investigación fue evaluar el efecto de la alimentación de cinco especies de chinches (Hemiptera: Pentatomidae y Coreidae) sobre frutos de nogal pecanero, en distintas fases fenológicas de crecimiento y desarrollo de la nuez, en Delicias, Chihuahua, México. Mediante la técnica de inclusión-exclusión de insectos en campo y con el análisis electroforético del tracto digestivo de las chinches en laboratorio. El experimento se llevó a cabo de 2000-2003 en la región de Delicias. La especie Brochymena sulcata (Van Duzee) no causó ni caída de frutos ni manchado de la almendra; en contraste, Leptoglossus zonatus (Dallas), Leptoglossus clypealis Heidemann y Chlorochroa ligata (Say) sí causaron caída de nueces, cuya intensidad varió con la fase de crecimiento y desarrollo del fruto. Durante el período de llenado de la almendra y apertura del ruezno, L. zonatus y C. ligata causaron manchado significativo de la almendra, mientras que Euschistus servus (Say) sólo lo hizo de manera leve. El análisis del tracto digestivo de B. sulcata mostró la presencia de isoenzimas de masa molecular similar a las del brote del nogal y diferentes a las del ruezno o la almendra. En la digesta de L. zonatus se encontraron isoenzimas similares a las de la almendra, pero no a las del brote. Los estudios demostraron que B. sulcata no es plaga del fruto, mientras que L. zonatus, L. clypealis y C. ligata son plagas potenciales del fruto durante la fase final de crecimiento del mismo, en el llenado de la almendra y hasta la cosecha. E. servus es una especie de importancia menor en las huertas de nogal en Delicias, Chihuahua.

          Translated abstract

          The objective of this study was to evaluate the feeding damage that five different bug species (Hemiptera: Pentatomidae and Coreidae) cause on pecan nuts at different fruit phenological stages. Throughout the technique of including-excluding, stink bugs in pecan shoot terminals were sampled in the field and electrophoretical techniques were used to analyze the content of the digestive track of the bugs in the laboratory. The experiment was carried out from 2000 to 2003 at Delicias, Chihuahua, Mexico. The species Brochymena sulcata (Van Duzee) did not provoke fruit drop or staining on the pecan kernel. On the contrary, Leptoglossus zonatus, L. clypealis, and Chlorochroa ligata caused nut drop whose intensity was related to nut development phase. During the period from nut filling to shuck opening, L. zonatus and C. ligata caused most of the kernel staining damage, while Euschistus servus showed a slight staining effect during this period. The analysis of the digestive track of B. sulcata, showed isoenzymes closely related to the plant growing points and different from these of nut shuck or kernel. While for L. zonatus isozymes closely resembling kernel isoenzymes were found, and different to these from the shoot tissue. Results indicate that B. sulcata does not feed on nuts, whereas L. zonatus L. clypealis and C. ligata are potential fruit pests during the late development stage of the nut, kernel filling and until harvest maturity. E. servus should not be considered an important pecan pest in Delicias, Chihuahua.
