Abstract

Ophelimus near migdanorum, a foliage gall wasp-inducer of Eucalyptus, is recorded for the first time in Colombia, infesting both mature ornamental trees of Eucalyptus globulus (Labill.) and monoculture plantations in the periurban forest in the city of Bogotá. The parasitoid Closterocerus chamaeleon was also emerged from the galled foliage. The spread of this pest and its parasitoid in other Eucalyptus species planted in Colombia has not been evaluated.

Highlights

Eucalyptus (Myrtaceae) is the most planted tree genus for commercial purposes in Colombia
Eucalyptus globulus (Labill.) was introduced in Colombia at the beginning of the 20th century, and during the decades of 20 ́s and 30 ́s was used in reforestation programs to protect soils around the rivers San Cristóbal, San Francisco, and Arzobispo, around the city of Bogotá (Bustos and Venegas 1975)
Four Ophelimus species are known to occur outside Australia attacking eucalypts
