High-throughput phenotyping technology for corn ears
… that allows for high-throughput phenotyping of corn ears, based on an existing imaging arrangement that produces frontal views of the ears. This thesis describes the development of machine vision algorithms that measure overall ear parameters such as ear length, ear diameter, and cap percentage …

Stink bug-Fusarium interactions and mitigation of associated mycotoxin contamination of corn in the mid-Atlantic, U.S.
… damage to a variety of crops including field corn (Zea mays). Frequency and size of stink bug infestations have increased in corn fields in the Mid-Atlantic U.S., and there are growing concerns that these infestations may contribute to reductions in grain quality including increased mycotoxin …

Stenocarpella Maydis: Identification, Management, and Population Diversity
<p>Diplodia ear rot (DER) has been a persistent corn disease across the Midwest, and in recent years it has become an annual problem. The objectives of this study were to i) develop a molecular assay for the identification of Stenocarpella maydis, causal agent of DER, ii) evaluate the effect of …

Development of microbial control for lepidopteran pests of the corn ear
… evaluated in the laboratory and in the field on corn. The virulence of the entomopathogens for Ostrinia nubilalis (Hubner) and Spodoptera frugiperda (J. E. Smith) was also evaluated in the laboratory;Three Bt products (HD-1-S-1980, Javelin°ler, and XenTari°ler) and AfMNPV were tested in the …

Improving Integrated Pest Management in Sweet Corn System
Corn earworm (CEW), Helicoverpa zea (Boddie), (Lepidoptera: Noctuidae) is a common insect pest of sweet corn in the United States. The larvae cause chewing damage on corn ears rendering them unmarketable. Traditionally, growers have controlled CEW in sweet corn using multiple applications of …

Modeling insect resistance to transgenic corn and cowpea
… on the IRM requirements of both Bt cotton and Bt corn plant-incorporated protectants (PIPs) since the late 1990s. For my dissertation research, I built four species-specific, simulation models to study the evolution of resistance by four insect pests of corn or cowpea to transgenic crops to 1) …
