Research Description

My research broadly explores the relationship between biodiversity and ecosystem service provisioning in agriculture. More specifically, my dissertation project will evaluate how changes in biodiversity at multiple spatial scales (landscape- and field-scale) influences biological control of arthropod pests in North Coast wine grape vineyards. Previous studies have shown that the area and diversity of natural habitats surrounding an agroecosystem (landscape-scale diversity) can influence biological control of pests. Similarly, additional studies have demonstrated that increasing habitat diversity within an agroecosystem (field-scale diversity) can also influence biological control of pests. As such, it is thought that the ability of on-farm habitat diversification to enhance biological control may be contingent upon the type of landscape within which the farm is situated.

My project evaluates the performance of a specific on-farm habitat diversification practice (floral resource provisioning using flowering summer cover crops) in 25 vineyards situated in different landscapes ranging from low to high diversity. The goal of this study is to better understand how natural habitats surrounding vineyards contribute to biological control and attempt to determine thresholds of landscape diversity within which the use of floral resource provisioning most effectively enhances biological control.

The focal pest of this study is the western grape leafhopper (Cicadellidae: Erythroneura elegantula) and it's key egg-parasitoids in the genus Anagrus (Mymaridae: Anagrus erythroneura and Anagrus daanei). This study is being conducted in collaboration with 30 commercial wine grape growers in Napa and Sonoma County who we have been working with since 2008.

Following graduate school my intention is to work in Cooperative Extension or the USDA Agriculture Research Service (USDA-ARS).
