Perimeter Cropping As a Means of Reducing Insect Injury and Increasing Crop Yield
… insect known to injure a broad range of cucurbit crops. Many studies have focused on insecticide management of this insect in squash (<em>Cucurbita</em>) and pumpkin (<em>Cucurbita pepo</em> Linnaeus) production; however, little work has been documented on organic approaches to reduce or eliminate …

Investigating host plant selection of harlequin bug, Murgantia histrionica (Hahn), in order to improve a trap cropping system for its management
… Murgantia histrionica (Hahn), is a pest of cole crops. Alternative control strategies were investigated for control of HB, including trap cropping and systemic neonicotinoid insecticide applications. Potential trap crops, mustard (Brassica juncea "Southern Giant Curled" ), rapeseed (B. napus …

Interactions between nematodes, potato and soil-borne micro-organisms and their effect on the management of potato cyst nematodes
… (PCN) cause significant damage to the potato crop worldwide and growers experience economic losses related to yield loss and the cost of control measures. Experiments were set up to further elucidate the complex tritrophic PCNpotato-soil bacteria relationship. Bacterial strains isolated from …

Pest Management of Japanese Beetle (Coleoptera: Scarabaeidae) and a Study of Stink Bug (Hemiptera: Pentatomidae) Injury on Primocane-bearing Caneberries in Southwest Virginia
… Therefore, the efficacy of geranium as a trap crop for JB may be limited. The stink bug species within the caneberries were identified (2008-2009) and Euschistus servus (Say) made up 48.1 % of the overall species composition. Stink bug injury to ripening raspberries was identified as small …

Ecology and management of wireworms (Coleoptera: Elateridae) in conventional and organic production systems
… 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 effective chemical approach in most crops. Thus, developing an effective alternative …

Investigations of the integrated pest management of Colorado potato beetle, Leptinotarsa decemlineata (Say): Host plant preference, development of semiochemical-based strategies, and evaluation of a novel insecticide
… Chrysomelidae), a major pest of solanaceous crops in the U.S., there has been little use of this knowledge in pest management. To better understand host plant selection by CPB, field and laboratory-choice experiments were conducted in Virginia. In laboratory studies, CPB preferred potato over …

Aggregation Pheromone Biosynthesis and Engineering in Plants for Stinkbug Pest Management
… pathways in plants to develop new forms of trap crops and agricultural practices for pest management. The harlequin bug, Murgantia histrionica, a specialist pest on crucifer crops, produces the sesquiterpene, murgantiol, as a male-specific aggregation pheromone. Similarly, the southern green …

Toward developing pheromone emitting trap crops: Metabolic engineering of an aggregation pheromone for enhanced attraction of Phyllotreta cruciferae
Pheromone lures and trap crops are appealing pest management tools that use insect and/or plant volatiles to reduce pest populations on crops of interest. Generating pheromone-emitting trap plants may allow for a continuing and highly-specific attraction of insect pests without repeated and costly …
