Escarabajos de la corteza presentes en plantaciones de Pinus radiata en Chile

Abstract

The flight curves of Hylurgus ligniperda, Hylastes ater, Xileborinus saxeseni, Orthotomicus erosus (introduced species) and Gnathotrupes spp. (native species) in Pinus radiata stands are presented in this study. We used funnel traps in four stands, two located in the Valdivia province and two in the Malleco province. The captures were carried out bimonthly over five months, and the greatest abundance was found in spring-summer populations, when the majority of the forest companies concentrate their harvests. For this reason, the probability is very high that these bark beetles colonize the wood, with subsequent damage to the primary products.
