Se estimó la diversidad y fluctuación anual de cerambícidos asociados al borde e interior de una selva tropical. La captura de insectos se realizó con trampas de intercepción cebadas con alcohol etílico y luz ultravioleta como atrayente. Se recolectaron 295 especímenes de tres subfamilias, pertenecientes a 56 especies de 38 géneros. Lamiinae fue la subfamilia con mayor riqueza, con 40 especies distribuidas en 20 géneros, para Cerambycinae se recolectaron 14 especies de 12 géneros y para Parandrinae dos especies de un género. El género con mayor abundancia fue Leptostylus con ocho especies. Se identificaron seis especies como nuevos registros para México y 29 para Tabasco. En el borde de la selva se recolectaron 155 especímenes de dos subfamilias, pertenecientes a 37 especies de 26 géneros. En el interior se recolectaron 140 especímenes de tres subfamilias pertenecientes a 36 especies de 26 géneros. Se determinó que las comunidades comparten 17 especies. El mayor valor de diversidad verdadera se obtuvo en el borde con 15,96 y la menor en el interior con 12,69. Se determinó que los valores de Δ, Δ* y Δ+ implican una baja separación filogenética entre las especies de cerambícidos en ambas comunidades. La fluctuación temporal de la comunidad de cerambícidos presentó los máximos valores de abundancia en febrero, mayo y agosto, meses donde se registra una reducción en la precipitación. Finalmente, la curva de acumulación de especies aún no presenta una asíntota, por lo que se podría incrementar los nuevos registros
<p><strong>Background.</strong> In tropical ecosystems, a great diversity of bark beetles and borers can be recognized, however, this diversity could be underrepresented due to the fact that the studies have been carried out mostly below 2 m in height, which makes it necessary to study them more widely and effectively. <strong>Objective</strong>. To analyze the vertical distribution of Scolytinae, Platypodinae (Curculionidae) and Bostrichidae at the edge and interior of a tropical forest in Tabasco, Mexico. <strong>Methodology. </strong>The study was carried out in the high evergreen rainforest of the Sierra el Madrigal in the municipality of Teapa, Tabasco, Mexico. The capture of insects was carried out with flight interception traps baited with 70% ethanol at three different heights: 1.5, 6 and 12 m. <strong>Results.</strong> The diversity index (<sup>1</sup>D) showed that the greatest diversity at the edge and interior of the forest is at 1.5 m. However, the traps at the edge located 12 m high captured the greatest richness, and the maximum richness in the interior was recorded at 1.5 m. Stratification of species richness was presented at the edge and interior of the forest. Statistical differences in abundance were found between the evaluated heights: at the edge, these occurred in January, April, October and November; and in the interior, in April. According to the diversity estimation (<sup>1</sup>D), statistical differences were presented in the months of April and October at the edge of the vegetation, and in the interior in March, April and June.<strong> Implications.</strong> The results provide a broader picture of the vertical distribution of the insects studied here, which are important in the dynamics of forest ecosystems. <strong>Conclusion. </strong>The diversity and abundance of insects change over time, and that more detailed studies are lacking to know the degree of variations associated with environmental variables.</p>
