Se realizó un estudio para determinar el efecto que ocasiona el disturbio en la vegetación sobre la riqueza, diversidad y abundancia de familias de Coleoptera presentes en un fragmento de Matorral, en Ciudad Victoria, Tamaulipas. El muestreo se realizó durante un año, mediante recolectas en cuadrantes de 100 m2 con red entomológica de golpeo sobre la vegetación herbácea y arbustiva en tres zonas con diferente grado de conservación: conservada, semiconservada y perturbada. Se obtuvieron un total de 2,358 ejemplares pertenecientes a 24 familias, siendo Chrysomelidae la familia dominante en los tres sitios. La abundancia y riqueza de coleópteros aumenta con el disturbio, mientras que la diversidad es mayor en la zona semiconservada. Por otra parte, el número de familias disminuye con el aumento en el grado de conservación de las zonas. Los resultados aquí obtenidos constituyen uno de los primeros análisis en la zona norte del país sobre este importante tema y representan una base para estudios posteriores en la región. Se establece como prioritaria la protección de la vegetación del Matorral en el noreste de México, ya que los efectos particulares sobre las especies de este grupo aún no se conocen, y es posible que muchas puedan desaparecer.
