Oregmopyga peruviana, plaga de Vitis vinifera, reduce la producción de uva y en infestaciones fuertes puede provocar la muerte de la planta. La investigación tuvo como objetivo obtener información del ciclo de vida, comportamiento biológico, plantas hospederas y agentes de control biológico de la plaga mediante observación en laboratorio y campo, a través de análisis descriptivos. Se determinó que O. peruviana tiene un ciclo de vida de 22,4 ± 2,06 días, con una capacidad de oviposición de 12,6 ± 1,9 huevos*hembra-1, periodo de incubación de 5,5 ± 0,52 días y periodo ninfal de 16,8 ± 2,13 días; por su comportamiento biológico, las ninfas son móviles y las hembras adultas estacionarias, sensibles a la alteración de su hábitat y mueren cuando la corteza es retirada; no se encontraron plantas hospederas, se destaca la presencia de un insecto parasitoide (Himenóptera: E...

Oregmopyga peruviana, pest of the V. vinifera, reduces the production of the grape and in strong infestations provokes the death of the plant. The research aimed to obtain information on the life cycle, biological behavior, host plants and biological control agents of the pest through laboratory and field observation, through descriptive analysis. O. peruviana was determined to have a life cycle of 22.4 ± 2.06 days, with an oviposition capacity of 12.6 ± 1.9 eggs*female-1, incubation period of 5.5 ± 0.52 days and nymphal period of 16.8 ± 2.13 days; biological behavior, nymphs are mobile and adult females are stationary, sensitive to the alteration of its habitat and die when the bark is removed. No host plants were found, highlights the presence of a parasite insect (Hymenoptera: Encyrtidae), a predator Sympherobius sp. (Neuroptera: Hemerobiidae), and Pyroderces sp. (Lepidoptera: Cos...

Oregmopyga peruviana, pest of the vine, causes damage that reduce the yield and strong infestations provoke the death of the plant. It is present along the Peruvian coast, being a very important pest. The objective of the study is to determine the individual efficacy of nine treatments (buprofezin 25 g·hL-1, chlorpyrifos 96 g·hL-1, pure vinasse, spirotetramat 474.3 g·hL-1, imidacloprid SC 1435 g·hL-1, imidacloprid WG 17.5 g·hL-1, M. anisopliae and B. bassiana 333.3 x 1012 CFU·hL-1, thiamethoxam 900 g·hL-1 and dinotefuran 680 g·hL-1) in different phenological periods. Each treatment was compared with its control using the Student's t-test for independent variables (p ≤ 0.05). In addition, the control percentage was determined using the Henderson and Tilton formula, obtaining for buprofezin 87.4%, chlorpyrifos 84.2%, vinasse 70.1%, spirotetramat 97.2%, imidacloprid WG 95.5%, imid...
