| population genetic structure and genetic diversity of soybean aphid collections from the usa, south korea, and japan. | following its recent invasion of north america, the soybean aphid (aphis glycines matsumura) has become the number one insect pest of soybean (glycine max l. merr.) in the north central states of the usa. a few studies have been conducted on the population genetic structure and genetic diversity of the soybean aphid and the source of its invasion in north america. molecular markers, such as simple sequence repeats (ssrs) are very useful in the evaluation of population structure and genetic diver ... | 2013 | 23957674 |
| development of soybean aphid genomic ssr markers using next generation sequencing. | simple sequence repeats (ssrs) or microsatellites are very useful molecular markers, owing to their locus-specific codominant and multiallelic nature, high abundance in the genome, and high rates of transferability across species. the soybean aphid ( aphis glycines matsumura) has become the most damaging insect pest of soybean ( glycine max (l.) merr.) in north america, since it was first found in the midwest of the united states in 2000. biotypes of the soybean aphid capable of colonizing newly ... | 2011 | 21529140 |
| phenology and abundance of bean leaf beetle (coleoptera: chrysomelidae) in eastern south dakota on alfalfa and soybean relative to tillage, fertilization, and yield. | phenology and abundance of bean leaf beetles, cerotoma trifurcata (förster), were examined throughout two eastern south dakota growing seasons in relation to grain yields in chisel- and ridge-tilled soybeans [glycine max (l.) merrill] grown in 2-yr rotation with corn (zea mays l.) with and without added nitrogen (n). populations were also sampled early and late season in alfalfa (medicago sativa l.). beetles were present in alfalfa by late may and most were reproductively active within a week, b ... | 2010 | 20550786 |
| field and laboratory evaluations of soybean lines against soybean aphid (hemiptera: aphididae). | the soybean aphid, aphis glycines matsumura (hemiptera: aphididae), is a major pest of soybean, glycine max (l.). merr., that significantly reduces yield in northern production areas of north america. insecticides are widely used to control soybean aphid outbreaks, but efforts are underway to develop host plant resistance as an effective alternative management strategy. here, previously identified resistant lines were evaluated in laboratory tests against field-collected populations of soybean a ... | 2012 | 22606833 |
