NATIVE HABITAT RESTORATION IN EASTERN WASHINGTON WINE VINEYARDS AS A PEST MANAGEMENT STRATEGY
(2019)Perennial crop systems such as wine grapes have begun using cover crops and hedgerows to increase beneficial insects and promote sustainable vineyard management in areas such as New Zealand and California. However, in arid ... -
SYSTEM-WIDE STUDY OF WOOLLY APPLE APHID
(2018)Woolly apple aphid, Eriosoma lanigerum (Hausmann), is an increasingly important pest in apple orchards worldwide and is difficult to manage with currently available tactics. To address the need for new knowledge and tactics ... -
RECIPROCAL INTERACTIONS BETWEEN NON-VECTOR COMMUNITY MEMBERS AND AN INSECT-TRANSMITTED PLANT PATHOGEN
(2017)Plant viruses interact with arthropod vectors in complex ecosystems consisting of many different components. Non-vector insect herbivores and plant-mutualistic bacteria are often present in these systems, and may have ... -
USING NEW MOLECULAR TOOLS TO EXPLORE HOW ORGANIC FARMING IMPACTS TOP-DOWN AND BOTTOM-UP REGULATION OF POTATO HERBIVORES
(2017)Herbivorous agricultural pests are simultaneously threatened by predatory natural enemies and by toxic plant defenses. Both these “top down” and “bottom up” forces might be enhanced under organic farm management. For ... -
Proximate mechanisms of condition-dependent exaggerated weapon growth in the Asian rhinoceros beetle Trypoxylus dichotomus (Kono)
(2016)Sexual selection as an evolutionary force is responsible for generating some of the most iconic morphologies in the animal kingdom. My dissertation utilizes the Asian rhinoceros beetle, Trypoxylus dichotomus (Kono), to ... -
Lethal and non-lethal effects of predators on Culex mosquitoes: implications for pathogen transmission
(2016)Biodiversity loss, especially at higher trophic levels, can degrade critical ecosystem services such as disease regulation. Predators play pivotal roles in regulating ecosystem services by impacting the abundance, distribution, ... -
Psyllid ecology and biodiversity in the Pacific Northwest
(2016)Potato is the fourth-most-valuable commodity in Washington State. The emergence of zebra chip disease (“ZC”) has triggered economic losses in the U.S. Pacific Northwest (“PNW”) with a ca. 7% increment in the total cost of ... -
Pollinator-mediated gene flow in and among fields of alfalfa produced for seed
(2015)Cross-pollination by bees is necessary for commercial alfalfa seed production. To maintain varietal purity in alfalfa, seed producers adhere to spatial isolation standards to minimize or prevent bee flight and subsequent ... -
Phytoseiids as biological control agents of phytophagous mites in Washington apple orchards
(2015)The integrated mite management (IMM) program in Washington has depended on the biological control of spider mites provided by Galendromus occidentalis (Nesbitt). We explored methods of improving this program. A series of ... -
COMPARATIVE BIOLOGY OF POTATO PSYLLID, BACTERICERA COCKERELLI (HEMIPTERA: TRIOZIDAE) HAPLOTYPES
(2014)Zebra chip, a new and economically important disease of potato, is threatening potato production in the United States, Mexico, Central America, and New Zealand. The disease is associated with the bacterium `Candidatus ... -
EPIGEAL INSECT COMMUNITIES & NOVEL PEST MANAGEMENT STRATEGIES IN PACIFIC NORTHWEST HYBRID POPLAR PLANTATIONS
(2013)Hybrid poplars are a short rotation woody crop grown for a variety of target markets including paper pulp, saw timber, and biofuels in the Pacific Northwest. Development of pest control strategies within hybrid poplar ... -
PHEROMONE-BASED MONITORING OF Pseudococcus maritimus AND INTRA AND INTERSPECIFIC VECTOR EFFICIENCY OF Parthenolecanium corni AND Pseudococcus maritimus AMONG AND BETWEEN Vitis x labruscana L. AND Vitis vinifera
(2013)Grapes have a major economic impact on the state of Washington, which is the number one producer of Concord juice grapes in the United States and the second largest producer of wine grapes in the United States, after ... -
Exploring consumption by two generalist hemipteran predators in potatoes using molecular gut content analysis and behavioral studies
(2013)Molecular gut-content analysis is an established and increasingly important approach for tracking arthropod predation in the field. Previously, it is difficult to know what hemipteran generalist predators consume because ... -
Diversity by design: Exploring the use of trap crops and companion plants to control Phyllotreta cruciferae, the crucifer flea beetle, in broccoli
(2012)The crucifer flea beetle (CFB), -
RESOURCE PARTITIONING BY PREDATORS IMPACTS INSECT COMMUNITIES
(2011)More-diverse consumer communities typically extract more resources, a phenomenon often attributed to resource partitioning. However, convincingly demonstrating this role of resource partitioning has been difficult. In some ...
