%X . Monalonion velezangeli is considered one of the most harmful pests of avocado cv. Hass, as far as it attacks vegetative buds, flowers and fruits during all the productive stages of the crop. This situation is aggravated by the lack of knowledge on insect preferences and their relationship with crop phenology. As a contribution to the management of this insect, we studied the relationship between plant phenology and the presence of M. velezangeli, as well as its preferences across tree strata and structures. Data were obtained from six orchards located in the Colombian departments of Antioquia, Caldas and Quind赤o. After randomly selecting 20 trees at each orchard, 12 branches were marked on each tree, covering the combinations of the four cardinal points with three plant strata (low, medium and high). During a period of 12 months, each branch was monitored by recording its phenological stage (vegetative, flowering and fruiting), the number of individuals of M. velezangeli and the presence of fresh damages on it. An analysis of variance determined that the presence of the insect and its damage were more abundant on the flowering and fruiting branches than on the vegetative ones, as well as in the medium and upper strata of the trees. The damage caused by M. velezangeli was observed to be significantly higher in the reproductive structures (flowers and fruits) as compared to the vegetative structures. Resumen. Monalonion velezangeli es considerada una de las principales plagas del aguacate cv. Hass en Colombia, debido a que ataca brotes vegetativos, flores y frutos, durante todas las etapas productivas del cultivo. Esta situaci車n se ve agravada por el desconocimiento de las preferencias del insecto, as赤 como de su relaci車n con la fenolog赤a de la planta. Como un aporte al manejo de este insecto, se estudi車 la relaci車n entre la fenolog赤a de la planta y la presencia de Monalonion, as赤 como sus preferencias por estructura y estrato. Las observaciones se hicieron en seis huertos ubicados en los departamentos de Antioquia, Caldas y Quind赤o (Colombia). Se eligieron 20 芍rboles por finca; en cada uno, se marcaron 12 ramas que correspond赤an a las combinaciones de los cuatro puntos cardinales en tres estratos (bajo, medio y alto). En la rama seleccionada se registr車, durante 12 meses, su estado fenol車gico (vegetativo, floraci車n o fructificaci車n), el n迆mero de individuos de M. velezangeli y los da os frescos presentes. Mediante an芍lisis de varianza, se determin車 que la presencia del insecto, as赤 como su da o fueron mayores sobre las ramas en floraci車n y fruc
