Life cycle, biological behavior, host plants and biological control agents of Oregmopyga peruviana (Granara de Willink & Díaz) (Hemiptera: Coccoidea:
Eriococcidae) in Vitis vinifera

Oregmopyga peruviana, pest of the V. vinifera, reduces the production of the grape and in strong infestations provokes the death of the plant. This 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 alternative host plants were found, and there was a presence of a parasite insect (Hymenoptera: Encyrtidae), a predator Sympherobius sp. (Neuroptera: Hemerobiidae), and Pyroderces sp. (Lepidoptera: Cosmopterigidae). The results show that O. peruviana is a specific V. vinifera pest and only attacks exclusively below the bark of trunks and lignified branches, the nymphs apparently being the colonizers. O. peruviana has native biological control agents.
