Taylor's power law and Iwao's patchiness regression were used to analyze spatial distribution of eggs of the Diaprepes root weevil, Diaprepes abbreviatus (L.), on silver buttonwood trees, Conocarpus erectus, during 1997 and 1998. Taylor's power law and Iwao's patchiness regression provided similar descriptions of variance-mean relationship for egg distribution within trees. Sample size requirements were determined. Information presented in this paper should help to improve accuracy and efficiency in sampling of the weevil eggs in the future. (author) [Spanish] Se utilizaron la ley de Taylor y la regresion de Iwao para analizar la distribucion de los huevos del picudo Diaprepes, Diaprepes abbreviatus (L.) en arboles de boton plateado, Conocarpus erectus. Los estudios fueron realizados durante 1997 y 1998. Tanto la ley de Taylor como la regression de Iwao dieron resultados similares en cuanto a la relacion de la varianza y el promedio para la distribucion de huevos del picudo en los arboles. Se determinaron los requerimentos del tamano del numero de muestras. En un futuro, la informacion que se presenta en este articulo puede ayudar a mejorar la eficiencia del muestreo de huevos de este picudo. (author)
