**The Temperate Tree Fruit and Vegetable Research Unit conducts research in three areas: Biology and management of pests and pathogens of tree fruits, biology and management of pests and pathogens of potatoes, and potato germplasm improvement. We also contribute to national IR-4 efforts to provide data needed for regulatory approval of pesticides in specialty and minor use crops.**
 **We conduct research on biology and management of tree fruit pests, including fruit flies, codling moth, pear psylla, northern giant hornet, and leafhopper vectors of the X-disease pathogen.  Research areas include plant-insect interactions, ecology, biological control, chemical ecology, physiology, and genetics.**
 **We conduct research on biology and management of insects that vector pathogens of potato and other vegetable crops.  Top left photo shows a parasitoid emerging from a beet leafhopper.  The bottom right photo shows zebra chip symptoms in potato tubers.**
 **We strive to develop new potato cultivars with superior pest and disease resistance, enhanced amounts of phytonutrients, and better quality that enhance food security, sustainability and protect profitability and jobs.**
 The mission of the IR-4 Project is to facilitate regulatory approval of sustainable pest management technology for specialty crops and specialty uses to promote public well-being. In this picture an IR-4 technician at the Temperate Tree Fruit and Vegetable Research Laboratory checks on an experiment.
