In Brazil this pest was detected in1955 in South Brazil and has been spread to Southeast in last 50 years. The ESB has beenconsidered under control due the parasitism by its egg parasitoid Anaphes nitens (Hymenoptera:Mymaridae) in five Brazilian States. In December 2012 a new outbreak was recorded in Southregion of Sao Paulo State, causing intense defoliation in clonal plantations. Early evaluationshave demonstrated a reduced parasitism rate in this region (30-60%). Nowadays, ESB hasspread for new areas in Sao Paulo State and in Parana State, affecting more than 20,000 ha ofEucalyptus plantations in 2016 and reducing the MAI in 10.2 to 42.8 m3/ha/year, accordingEucalyptus clone and age. Ongoing studies have showed the reduced A. nitens effectivenessmay be related with the occurrence of some endosymbionts (Rickettsia, Serratia and Yersinia)in the parasitoid, affecting parasitoid reproduction. Other possible cause is the occurrence of aparasite mite in egg clusters (genus Pyemotes), affecting viability of G. platensis eggs, includingparasitized eggs. New management strategies have been proposed, including introduction ofnew Anaphes species (A. tasmaniae and A. inexpectatus) for eggs, bioinseticides application,with Beauveria bassiana, Metarhizium anisopliae and Bt var. tenebrionis for larvae, use ofentomopathogenic nematodes to control pupae in soil and predatory bugs (Podisus nigrispinus)to control adultsKeywords: Eucalyptus snout beetle, biological control, IPM, forest pest, parasitoid∗Speaker†Corresponding author: cwilcken@uol.com.br186
