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.

墨西哥杜兰戈的 Meteorus laphygmae 和 Meteorus arizonensis 之间的形态变化
摘要由于形态鉴定和 bank® 基因的遗传比较非常复杂(没有 M. arizonensis 的序列可作比较),因此对在杜兰戈州三个地方采集的 Meteorus 属寄生虫进行了形态计量分析,以了解其种类。为此,我们记录了表型变化,计算了形态比例,并使用贝叶斯推断法进行了系统发育重建。通过形态分析,我们可以将雌性和雄性划分为两组,与体色无关。 此外,我们还观察到它们的比例测量值存在重叠,这表明差异与标本的性别有关。在遗传标记 COI mDNA 方面,来自杜兰戈的标本,无论其颜色和肤色模式如何,都形成了一个单一的系统发生群,遗传变异在 0 至 0.8%之间。这表明,在杜兰戈只发现了 Meteorus 属的一种寄生虫,其颜色变化很大,显然与分类学或地理差异无关。摘要对墨西哥杜兰戈三个地点的 Meteorus 属寄生虫进行了形态计量分析,以确定其种类,因为形态鉴定和基因库®中的基因比较非常复杂(没有 M. arizonensis 序列可与之比较)。我们记录了表型变异,计算了形态比例,并使用贝叶斯推断法进行了系统发育重建。通过形态计量分析,我们可以将雌雄两类动物(不论体色如何)分成两组。此外,在测量它们的比例时也发现了重叠,这表明差异取决于标本的性别。在 COI DNAm 遗传标记方面,来自杜兰戈的标本,无论其体色和颜色模式如何,都形成了一个单一的系统发生群,遗传变异在 0 至 0.8%之间。这表明,在杜兰戈只发现了 Meteorus 属的一种寄生虫,其颜色变化很大,显然与分类学或地理差异无关。

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.
