"El cultivo de la papa afronta muchos problemas parasitológicos, uno de los cuales es la enfermedad conocida como punta morada, que en los últimos años ha causado pérdidas considerables en México y otros países; la zona productora de papa en Coahuila (Sierra de Arteaga)- Nuevo León (Navidad, Galeana), no es la excepción. Recientemente se ha considerado que este síndrome es ocasionado por la intervención de hongos, virus y fitoplasmas. estos últimos organismos son trasmitidos, entre otros por hemípteros de las familias Cicadellidae y Psyllidae."

"Potato crop face many parasitological problems, one of the them is the disease well known as purple top that in the last years caused important losses in México and others countries; the potato producing zone Coahuila (Sierra of Arteaga)- Nuevo León (Navidad, Galeana) is not the exception. Recently, it was considered that this syndrome is caused by fungus, virus and phytoplasmas. These last organisms are transmited, among others, by species of the families Cicadellidae and Psyllidae. In the potato region of Coahuila- Nuevo Leon, the entomofauna of natural enemies present in cultivated potato and adjacent weed is unknown, reason for that this work emphasize in parasitoids of the superfamilies Ichneumonoidea, Chalcidoidea, Cynipoidea, Proctotrupoidea, Bethyloidea and Scolioidea in the Order Hymenoptera. So, in adjacent weed to cultivated potato, 1,911 insects belonging to Order Hymenoptera were collected; 1, 775 were parasitoids from six superfamilies, 22 families, 32 subfamilies and 64 genera, whereas in cultivated potato only 98 specimens belonging to four superfamilies, six families, four subfamilies and four genera were obtained. Chalcidoidea and Eulophidae were the groups with more specimens as much weed as potato; Tetrastichus was the only genera obtained from Bactericera (= Paratrioza) cockerelli, the main pest in the crop at this moment"
