“…Maximum likelihood (ML) method with 1000 bootstraps was used based on the Tamura & Nei (1993) model, with uniform substitution rates among sites, all sites (gaps and/or missing data) used, and the ML heuristic method Nearest-Neighbour-Interchange. Included in the analyses were COI and CytC sequences from S. graminum collected in the USA (Shufran et al , 2000; Shufran, 2011; Shufran & Puterka, 2011) (table 4). DNA sequences were submitted to GenBank with accession numbers JN383531–JN383591 (COI) (table 3) and JN383592–JN383595 (CytC).…”

The greenbug, Schizaphis graminum (Rondani), is a major pest of cereals in some parts of the world and is of particular concern because it can be resistant to some insecticides and overcome the resistance of crops. In the UK, it has never been found on crops, but two rather little-known and closely-related species (Schizaphis holci and Schizaphis agrostis) are associated with the wild grasses, Holcus lanatus and Agrostis stolonifera. Since 1987, winged (alate) aphids morphologically resembling the greenbug have been found in increasing numbers in 12.2 m high suction-trap samples of the Rothamsted Insect Survey (RIS); hence, studies were undertaken to establish their identity. Clones (=asexual lineages) established from populations collected from H. lanatus in southern England showed strong preference for Holcus over Agrostis and Hordeum in laboratory tests and produced sexual morphs when transferred to short-day conditions, the males being apterous, as expected for S. holci. Multivariate morphometric comparisons of alatae caught in UK RIS suction traps in 2007 and 2011 with named specimens from museum collections, including S. graminum from many countries, indicated that the suction-trapped alatae were mostly S. agrostis and S. holci. Cytochrome c oxidase subunit I (COI) mtDNA obtained from 62 UK specimens from suction-traps had 95.4-100% sequence identity with US specimens of S. graminum. Two of the UK specimens had identical COI sequence to the US sorghum-adapted form of S. graminum, and these specimens also had 100% identity with a 640 bp fragment of nDNA CytC, indicating that this form of S. graminum may already be present in the UK. Present and future economic implications of these results are discussed.

Its cultivation over a very broad range of environments and its versatile utilization for the production of raw material for feed and food render it a top-four crop plant worldwide. Representing the temperate cereals of the Triticeae tribe (wheat, rye, triticale), barley has been used as experimental model since the era of classical genetics and cytogenetics-a role that has been reinforced along the development of contemporary biology and crop plant research.The generation of comprehensive genome sequence data is regarded as a cornerstone with major impact into all areas of modern barley research. Thus, we are convinced of the timeliness and importance to survey and reflect the current state of biotechnologically oriented barley research in the present volume of the Springer series Biotechnology in Agriculture and Forestry. Besides genome sequencing, major progress was achieved by deep sequencing-based transcriptomics, the establishment of comprehensive mutant panels and TILLING platforms, the generation of high-resolution genetic maps, efficient site-directed mutagenesis using customizable endonucleases, as well as the establishment of automa...

“…El pulgón verde de los cereales está ampliamente distribuido en Asia, África, Australia y América, convirtiéndose en una plaga de importancia económica. En México se registró por primera vez en 1972 (Peña & Sifuentes, 1972), siendo sus hospederos preferidos la avena, cebada, centeno, trigo, sorgo y otras gramíneas silvestres (Shufran, 2011). Así mismo, el pulgón amarillo del sorgo se reportó para México en 2013, en el estado de Tamaulipas, donde atacó principalmente cultivos de sorgo y causó pérdidas hasta del 100% (Maya-Hernández & Rodríguez-del-Bosque, 2014).…”

El pulgón amarillo del sorgo Melanaphis sacchari y el verde Schizaphis graminum son especies que coexisten en cultivos de sorgo. El pulgón verde se reportó por vez primera para México en 1972 en cultivos de avena, y el amarillo en 2013 en cultivo de sorgo, este último causando pérdidas hasta del 100%. Desde entonces, se realizan esfuerzos para su control, por ello, el objetivo de este estudio fue conocer los parasitoides de M. sacchari y S. graminum en cultivos de sorgo en Colima y Tamaulipas. En 2014 se realizaron muestreos en cinco localidades de Tamaulipas afectadas por el pulgón amarillo, donde se colectaron pulgones parasitados. La recolecta en Colima fue en 2016, realizándose semanalmente durante un ciclo completo del sorgo con red de barrido y colecta directa. Se registraron dos especies de parasitoides: Lysiphlebus testaceipes, donde se reconocieron a nivel molecular dos haplotipos, uno por estado, 15 especímenes en Tamaulipas emergiendo del pulgón amarillo y seis en Colima también emergiendo del pulgón amarillo y 127 recolectados con red en Colima y, Pachyneuron aphidis hiperparasitoide de L. testaceipes, se registraron tres individuos emergiendo de momias de M. sacchari en Tamaulipas y dos en Colima, además de 12 especímenes recolectados con red en este estado. En Colima, el pulgón verde y L. testaceipes mostraron mayor presencia durante el desarrollo de las hojas e iniciación de la panoja, mientras que el pulgón amarillo fue más abundante durante el desarrollo y llenado de los granos, durante esa etapa la presencia de parasitoides fue casi nula. Concluyendo que L. testaceipes y P. aphidis aparentemente muestran preferencia por S. graminum en el área de estudio.
