Ecology and management of wireworms (Coleoptera: Elateridae) in conventional and organic production systems
Wireworms are the subterranean larval stage of click beetles (Coleoptera: Elateridae), generalist herbivores that feed on a wide range of crops and cause serious damage. Wireworm management is challenging due to their long life cycle, subterranean habitat, wide range of host plants, and lack of …

A morphological study of some of the immature stages of Cryptohypnus nocturnus eschscholtz, and a study of some ecological factors concerning wireworms : a preliminary study
Wireworms, the larvae of the Elateridae, are among the most common and widely distributed pests of cultivated crops. They have undoubtedly caused some losses from the earliest days of agriculture, since their importance has been recognized from the beginning of economic entomology. Several species …

Effect of Nitrogen Rates, Planting Dates, and Irrigation Regimes on Potato Production in the Eastern Shore of Virginia
… Ca and H saturation percentages were linked to wireworm damage levels using classification algorithms. Similarly, K saturation percentage was identified as a potential predictor of nematode presence in this region. A second study was established with the objective of evaluating the effect of N …

Ecology of Root-Feeding Insect Assemblages in Fire-Manipulated Longleaf Pine-Wiregrass Ecosystems
Root-feeding insects can have top-down influence on vegetative composition and ecosystem processes; however, they may respond to bottom-up factors such as soil resources, site productivity, and disturbance. My research addressed the following questions: (1) Do disturbance (fire), vegetative …

Pest Management Studies of Early Season and Stalk-Boring Insects on Corn in Virginia
… white grubs (Coleoptera: Scarabaeidae) and wireworms (Coleoptera: Elateridae) in cornfields. In the first study, model variables included corn growth stage and larvae per plant. In both years of this study, larvae per plant had a significant effect on grain yield. Grain yield was reduced by …
