Abstract

In October 2015, sixteen 3.5-year-old teak trees were found dead in commercial plantations in São José de Quatro Marcos, Mato Grosso, Brazil. These trees had holes and ejected frass along the trunk. Based on morphology, the woodborers were identified as Steirastoma breve. This species is usually associated with Cecropia sp. (Urticaceae) and Wisteria sp. as natural hosts. It has been reported affecting cacao, Theobroma cacao, in Ecuador, Guadeloupe, Grenada, Martinique, Venezuela, Suriname and Trinidad and more recently in Rondônia, Brazil. This study reports the first occurrence of S. breve in teak plantations and characterize the damage caused by this beetle.
