seasonal phenology of aphis glycines (hemiptera: aphididae) and other aphid species in cultivated bean and noncrop habitats in wisconsin. | the occurrence of aphid-transmitted viruses in agricultural crops of the midwest and northeastern united states has become more frequent since the arrival and establishment of the soybean aphid, aphis glycines matsumura (hemiptera: aphididae). a. glycines is a competent vector of plant viruses and may be responsible for recent virus epidemics in wisconsin snap bean, phaseolus vulgaris l., fields. to determine whether vegetation surrounding crop fields could serve as sources of virus inocula, we ... | 2010 | 21061967 |
seasonal population dynamics of thrips (thysanoptera) in wisconsin and iowa soybean fields. | with the discovery of neohydatothrips variabilis (beach) as a vector of soybean vein necrosis virus (family bunyaviridae genus tospovirus), a relatively new pathogen of soybean, a multiyear study was initiated in wisconsin (2013 and 2014) and iowa (2014 and 2015) to determine the phenology and species composition of thrips in soybean fields. yellow sticky card traps were used to sample thrips at regular intervals in five counties within each state's primary soybean-growing region. the assemblage ... | 2017 | 28011679 |
rag virulence among soybean aphids (hemiptera: aphididae) in wisconsin. | soybean aphid, aphis glycines matsumura, a pest of soybean, glycine max (l.) merr., and native of asia, invaded north america sometime before 2000 and rapidly became the most significant insect pest of soybean in the upper midwest. plant resistance, a key component of integrated pest management, has received significant attention in the past decade, and several resistance (rag) genes have been identified. however, the efficacy of rag (resistance to aphis glycines) genes in suppressing aphid abun ... | 2015 | 26470137 |
