| population genetic structure of aphis glycines. | the soybean aphid (aphis glycines matsumura) is an invasive pest of cultivated soybean (glycine max l.) in north america. after the initial invasion in 2000, the aphid has quickly spread across most of the united states and canada, suggesting large-scale dispersal and rapid adaptation to new environments. using microsatellite markers from closely related species, we compared the genetic diversity and the amount of genetic differentiation within and among 2 south korean and 10 north american popu ... | 2009 | 19689913 |
| ovarian development and ovipositional preference of the western corn rootworm (coleoptera: chrysomelidae) variant in east central illinois. | the rotation of maize, zea mays l., and soybean, glycine max (l.) merr., has been the traditional cultural tactic to manage the western corn rootworm, diabrotica virgifera virgifera leconte, in the corn belt. the reduced effectiveness of this rotation as a pest management tool in east central illinois, northern indiana, and southern michigan can be explained by the shift in the ovipositional behavior of the new variant of western corn rootworm. the objective of this study was to evaluate the inf ... | 2004 | 15154460 |
| determination of isoflavone (genistein and daidzein) concentration of soybean seed as affected by environment and management inputs. | isoflavones, such as genistein and daidzein, are produced in soybean seed [glycine max (l.) merr.] and may be associated with health benefits in the human diet. more research is required to determine the effect of agronomic soybean treatments on isoflavone concentration. in this study from 2012 to 2014 at michigan state university and breckenridge locations, we have evaluated agronomic input management systems which are marketed to increase or protect potential soybean grain yield, including: ni ... | 2016 | 27981593 |
| feeding behavior comparison of soybean aphid (hemiptera: aphididae) biotypes on different soybean genotypes. | soybean aphids have become a serious pest of soybean, glycine max l. (merrill), since they were first detected in north america in 2000. three soybean aphid biotypes have been documented in the united states in the last 10 yr, but few studies have been done on their feeding behavior in the united states the electrical penetration graph is a convenient and successful tool to study the feeding behavior of piercing and sucking insects. this is the first attempt to study the feeding behavior differe ... | 2013 | 24224269 |
