Biological control of insect pests is the main focus of my research including native and exotic scarabs in New Zealand pastures, coconut rhinoceros beetle in the Pacific, as well as pests on eucalypts and cotton. My work on host range testing of biological control agents has led to an interest in native insects that have become pests on introduced crops. I also work more generally on integrated pest management in agriculture, horticulture and forestry.
