Abstract
En el año 1978, se produjo en dos regiones de la Sierra Maestra, una fuerte defoliación de masas semilleras de Pinus maestrensis (Bisse), provocada por el brote de la mosca de sierra Neodiprion merkeli Ross, cuya existencia no se había localizado en Cuba hasta la fecha. En el trabajo presentado se ofrecen detalles de la morfología de la plaga, y datos sobre su bionomía y sobre los factores limitantes del nivel de población. Además, se describen condiciones en las cuales ocurrió la aparición nociva de la plaga; se caracterizan los síntomas de los estragos y, en consecuencia, la magnitud de daños en la cosecha de las semillas. En conclusión, se recomiendan los métodos adecuados para la protección contra la plaga.
