El presente trabajo de investigación se desarrolló en tres caseríos de la provincia de Santiago de Chuco: Muchucayda ubicado a 3411 m.s.n.m., Muycan ubicado a 3091 m.s.n.m. y Chambuc ubicado a 2694 m.s.n.m. el objetivo fue evaluar las principales plagas insectiles en Vicia faba Var. Señorita. El diseño que se utilizó para realizar las evaluaciones de plagas insectiles fue utilizando un monitoreo en forma de zigzag. Los resultados demuestraron que la principal plaga insectil que se registró en el caserío de Muchucayda fue: Ridopsidius piercei con un índice de plantas cortadas de 11% y 24 % de infestación. En el caserío de Muycan la plaga insectil con mayor daño fue: Diabrotica spp. Cabrera con un grado de infestación del 54% y 60% de infestación y la plaga insectil con menor daño fue: Agrotis latifolia Massaro con un grado de infestación del 13% y 10% de infestación. En el caserío de Chambuc la principal plaga insectil con mayor daño fue: Diabrotica spp. Massaro con un grado de infestación del 65% y 71% de infestación; la plaga insectil con menor daño fue: Epitrix yanasara L. con un grado de infestación del 27% y 12% de infestación; estos daños de registraron en las etapas fenológicas de: ramificado, botón floral y floración; las plagas insectiles fueron controladas con un insecticida Cypermetrina, en una dosis 36 ml/mochila 18 l.
ABSTRACT The present investigation work was developed in three villages of the province of Santiago de Chuco: Muchucayda located at 3411 m.s.m., Muycan located at 3091 m.s.n.m. and Chambuc located at 2694 m.s.n.m. The objective was to evaluate the main insect pests in Vicia faba Var. Miss. The design that was used to perform the evaluations of insect pests was using a monitoring in the form of a zigzag. The results show that the main insect pest registered in the village of Muchucayda was: Ridopsidius piercei with an index of cut plants of 11% and 24% of infestation. In the farm of Muycan, the insect pest with the greatest damage was: Diabrotica spp. Cabrera with a degree of infestation of 54% and 60% of infestation and the insect pest with minor damage was: Agrotis latifolia Massaro with a degree of infestation of 13% and 10% of infestation. In the hamlet of Chambuc, the main insect pest with the greatest damage was: Diabrotica spp. Massaro with a degree of infestation of 65% and 71% of infestation; the insect pest with the least damage was: Epitrix yanasara L. with a degree of infestation of 27% and 12% of infestation; These damages were recorded in the phenological stages of: branched, floral bud and flowering; the insect pests were controlled with an insecticide Cypermethrin, in a dose 36 ml / backpack 18 l.
