ABSTRACT
Eucalyptus are hosts of several psyllid species. Among them, Ctenarytaina eucalypti (Maskell) is considered the most harmful to Eucalyptus globulus plantations. In Brazil, this pest has been observed in the state of Parana, and in 2005, it was found causing damage to plantations of E. globulus in Arroio Grande and Piratini cities, RS. The monophagous endoparasitoid Psyllaephagus pilosus Noyes was also observed parasitizing nymphs of C. eucalypti. This parasitoid has been shown to be highly efficient in controlling this psyllid species, making unnecessary the use of any other control method.
