Abstract
Resumen. Se realizó un análisis morfométrico de parasitoides del género Meteorus colectados en tres localidades de Durango, para conocer su especie, debido a la complejidad en la identificación morfológica y su comparación genética en el gen bank® (no existen secuencias de M. arizonensis con quien comparar). Para lo cual, se registró la variación fenotípica, se calcularon proporciones morfométricas y se realizó una reconstrucción filogenética mediante el método de inferencia bayesiana. El análisis morfométrico permitió formar dos grupos, correspondientes a machos y hembras, independientemente del color de su cuerpo, además se observó un solapamiento en las medidas de sus proporciones, lo que indicó que las diferencias son dependientes del sexo de los especímenes. Respecto al marcador genético COI ADNm, los ejemplares provenientes de Durango, independientemente del color y del patrón de coloración de éste, conformaron un sólo grupo filogenético, con una variación genética entre 0 y 0.8%. Lo anterior indica que, en Durango se encuentra una sola especie de parasitoides del género Meteorus, con una fuerte variación de color que, al parecer, no responde a diferencias taxonómicas o geográficas.

期刊介绍:
Manuscripts submitted for consideration for publication in the Southwestern Entomologist should report results of entomological research in the southwestern United States or Mexico or should report results of studies on entomological species, relevant to this region, which may be done elsewhere, provided such results are geographically applicable. Manuscripts that report results of routine laboratory or field experiments for which the primary purpose is gathering baseline data or those that report results of a continuous evaluation program such as preliminary pesticide evaluation experiments, species lists with no supporting biological data, or preliminary plant resistance evaluations are not acceptable. However, reports of experiments with insecticides, acaricides, and microbials are acceptable if they are comprehensive and include data related to economics, resistance, toxicology, or other broad subject areas. Bibliographies will not be published in Southwestern Entomologist.
