Abstract
En el presente trabajo se estiman las pérdidas en el volumen de madera activa existentes en el rodal a causa del ataque de Dioryctria horneana al fuste de Pinus cubensis. Se halló que el cambio de la madera a surtidos de menor valor (leña y desechos), se produce en mayor magnitud en el menor espaciamiento evaluado (2x2) y que esta pérdida (138 m³/ha) es altamente significativa en comparación con la reconocida para los cinco espaciamientos restantes considerados. La mayor pérdida registrada, multiplicada por la diferencia entre los precios de pino del país en bolo y la madera para combustible, asciende a 3 496 pesos por hectárea.
