| dc.description | The teak (Tectona grandis L.T.) is a forest species of economic importance for many countries worldwide. Its wood is highly appreciated and demanded for its quality. In cultivation there are a diverse entomofauna of beneficial organisms and those considered pests. Among these insects are the so-called scolithids belonging to the subfamily Scolytinae. The small beetles are classified into two large ecological groups, the bark beetles, and the ragweed beetles. The first are more specialized and carry out their development based on the feeding of the nutritional substances produced by the tree. The second group is characterized by being associated with symbiotic fungi, from which it obtains its food. Both groups are important in ecosystems because they are recyclers and some of these are considered important pests. The objective of this research was to compile information on the different genera that are related to the cultivation of teak in America. According to the information collected, it was determined that in all the countries where teak is grown, some genus of the scolithid group is present. The genera found were the following: Xyleborus, Xylosandrus, Euwallacea, Premnobius, Coccotrypes, Hypothenemus, Coptoborus, Xyleborinus, Trischidias, Cryptocarenus, Ambrosiodmus, Cnesinus, Araptus, Scolytus. Within the genera are the two ecological groups of scolithids, distributed in all the countries where teak is grown in America. | es_ES |

| dc.description.abstract | La teca (Tectona grandis L.T.), es una especie forestal de importancia económica para muchos países a nivel mundial. Su madera es muy apreciada y demandada por la calidad de esta. En el cultivo se encuentran una entomofauna diversa de organismos benéficos y los considerados plaga. Entre estos insectos se encuentran los llamados escolítidos pertenecientes a la subfamilia Scolytinae. Los pequeños escarabajos se clasifican en dos grandes grupos ecológicos, los escarabajos de corteza y los escarabajos de ambrosia. Los primeros son más especializados y realizan su desarrollo en base de la alimentación de las sustancias nutritivas que produce el árbol. El segundo grupo se caracterizan por estar asociados a hongos simbiontes, de los cuales obtienen su alimento. Los dos grupos son importantes en los ecosistemas por ser recicladores y algunos de estos son considerados plagas de importancia. El objetivo de la presente investigación fue copilar información sobre los diferentes géneros que se encuentran relacionados al cultivo de teca en América. De acuerdo con la información recabada, se logró determinar que en todos los países donde se cultiva la teca está presente algún género del grupo de los escolítidos. Los géneros encontrados fueron los siguientes: Xyleborus, Xylosandrus, Euwallacea, Premnobius, Coccotrypes, Hypothenemus, Coptoborus, Xyleborinus, Trischidias, Cryptocarenus, Ambrosiodmus, Cnesinus, Araptus, Scolytus. Dentro de los géneros se encuentran los dos grupos ecológicos de escolítidos, distribuidos en todos los países donde se cultiva la teca en América. | es_ES |
