The present research was to identify and determine the diversity of the scolitids, their abundance and diversity index associated with plantations of Tectona grandis L. f. This study was carried out at the La Mont, Santa Rosa and La Valentina sites, located in the Balzar canton, province of Guayas. To determine diversity, 36 flight intersection traps were placed at a height of 1.30 m, at ground level, the traps were primed with alcohol (96%) and distilled water. Insects were collected every eight days, during August, September and October. The identification was carried out in the microbiology laboratory of the State Technical University of Quevedo with the help of a stereomicroscope and dichotomous keys. To determine the abundance and diversity index, we proceeded to identify trees that presented symptoms of regressive death and vascular wilt, then nine diseased trees were removed per site and sectioned every four meters, later the wood was opened for the collection of insects, which were deposited in bottles with 70 ° alcohol, for the respective identification. The scolitids that were collected using the traps had a total of 9560 insects.

Palabras clave : Diversity; abundance; scolitids; symptomatology; dichotomous keys.
