My research program addresses the development of environmentally sound pest management options, with emphasis on tropical fruit and nut crops. My main research interest is biological control and its integration with other pest management options. A major component of my interest in biological control understanding how to quantify non-target risks and to plan introductions of biological control agents to have minimal impact on indigenous species, yet maximal impact upon pest populations.
Insect conservation is another of my research interests. Hawai'i provides an interesting location for the study of impacts of agriculture and other disturbances on endemic species. I hope to one day launch some projects on patterns of gall-insect diversity in the islands.
Extension projects include developing sampling plans and thresholds for pests of bananas and macadamia nuts, and training growers in IPM approaches, sampling and insect identification for the purpose of pest scouting. Click here for a short video on green stinkbug sampling. Training in sustainable pest management is also offered as part of a multidisciplinary project.
A Pacific Distance Diagnostics by Digital Imaging and Recommendation System is also being implemented, in an effort to enhance diagnostic and recommendation capacity for isolated islands throughout the Pacific.
