The influence of pheromone dispenser release rates, trap height and pheromone dispenser height on captures of leafrollers in Virginia apple orchards
… rates and longevities of several designs of pheromone dispensers for mating disruption of leafrollers and codling moth, Cydia pomonella (Linneaus). Release rates were described by linear equations for at least four months, but by the end of the season release rates tended to become erratic. …

Quantification and use of pheromone-baited milk-carton traps to monitor gypsy moth populations
… understanding of the dynamics of male gypsy moth-pheromone trap interactions and the ecological factors that influence moth capture in pheromone traps. Defoliation, the most obvious expression of high density gypsy moth populations, may have a significant influence on gypsy moth population …

Bionomics of Platynota flavedana Clemens and P. idaeusalis (Walker)(Lepidoptera: Tortricidae) in Virginia apple orchards
The effects of pheromone trap placement on male moth catches of both species were studied. For P. flavedana, traps hung at 2.1 and 3.0 meters captured the greatest number of moths. Trap heights of 1.2, 2.1, and 3.0 meters caught the greatest number of P. idaeusalis moths. The outside-the-canopy …

Effect of trap height on abundance and species diversity of cerambycid beetles captured in forests of east-central Illinois
Trapping surveys that target wood-boring insects are usually deployed in the forest understory simply for convenience, but the abundance and species diversity of captured insects may be greatly influenced by the height of traps above the ground. Here, I assess how the vertical position of traps …

Surveillance of grape berry moth, Paralobesia viteana Clemens (Lepidoptera: Tortricidae), in Virginia vineyards
My research addressed pheromone lure design and the activity of the grape berry moth, Paralobesia viteana, flight and infestation across three years of study. In my lure evaluations, I found all commercial lures contained impurities and inconsistencies that have implications for management. First, …

Survey of different mealybug species and attending ants and their management in Virginia vineyards
… ficus remained absent. Commercially available pheromone delta traps and adhesive bands were deployed to capture the male mealybugs, while numerically higher efficacy was observed in the adhesive band trap. Notably, the placement of adhesive band traps on the cordon and trunk revealed …

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 …
