Abstract
Las plagas del género Ethmia Hubner, desempeñan un importante papel dentro del complejo de defoliadores que atacan a Cordia gerascanthus en Cuba. En este trabajo se hace una descripción de tres especies de este género, detectadas en la provincia de La Habana: Ethmia subsimilis Wals., E. phylacis ornata Busck y E. phylacops Powell. Se ofrecen datos de su distribución nacional, hábitos y fluctuación de la densidad de población. Ethmia subsimilis resultó ser la más abundante en el período de estudio y para esta especie fue posible determinar el ciclo de vida y la relación entre la brotación de las plantas y su población.
