Predator-prey interactions involving the soybean aphid (Hemiptera: Aphididae) in Missouri
(University of Missouri--Columbia, 2007)
The recently introduced soybean aphid, Aphis glycines Matsumura, is found in all soybean growing areas within Missouri. Despite soybean aphid's widespread distribution, it has reached economic threshold in few soybean fields in Missouri. We...
Application of CRISPR/Cas9-mediated genome editing for studying soybean resistance to soybean cyst nematode
(University of Missouri--Columbia, 2016)
Soybean cyst nematode (SCN) Heterodera glycines has become one of the most economically important pathogens of soybean in the world. The main strategy of SCN management is planting resistant soybean cultivars. The main ...
Cover crop and rotation intensity effects on soil health and yield in corn-soybean cropping systems
(University of Missouri--Columbia, 2020)
soil health and cash crop yields for the long-term. The implementation of cover crops and crop rotation are widely promoted management strategies that have been shown to enhance soil health in agricultural systems, and may lead to increases in cash crop...
Comparing the diversity, geographic distribution, and intraspecific variation of subterranean termites (Reticulitermes: Isoptera: Rhinotermitidae) occuring in woodlands and urban environments of Missouri using morphology and 16s mtDNA
(University of Missouri--Columbia, 2007)
. In urban environments they feed upon dead wood, and therefore infest and destroy man-made wooden structures. Missouri is considered to have a moderate risk for termite infestations when compared with the states of the southeast part of the country. Despite...
Soybean emergence, growth, and development following corn stover removal
(University of Missouri--Columbia, 2012)
Columbia, Missouri in 2010 and 2011. The effects of two residue removal treatments (Baled and Not Baled), three cover crop treatments (rye, radish, and no cover crop) and two emergence class treatments (Early emergence and Late emergence) were analyzed...
Factors that influence the movement of Cauliflower mosaic virus in susceptible and resistant plants
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Since the first description of Cauliflower mosaic virus (CaMV), it has been the subject of many research papers, both as a model system for plant molecular virology...
Exploring the symbiotic relationship of plants and microbes by mass spectrometry imaging
(University of Missouri--Columbia, 2019)
Current practices in agriculture make use of chemical inputs including nitrogen fertilizers to provide high crop yields since nitrogen is often the limiting nutrient in field soil. However, nitrogen fertilizer use has negative impacts; such as due...
Influence of entomopathogenic fungi from forest and urban habitats on founding pairs of reticulitermes flavipes (rhinotermitidae)
(University of Missouri--Columbia, 2015)
termite colonies survive fungal invasions. This research focused on founding pairs of primary reproductives when colonies are smallest and there are only two termites. Because most termite colonies invading newer homes in Missouri are started...
