Our extension program covers molecular diagnostics and examination of insects important in agriculture in New York. We perform identification of invasive/exotic insects and differentiation of species that are morphologically difficult to identify, so as to provide information of insect pest occurrence to government regulatory staff, researchers and growers. We also examine insect population differentiation and movement, so as to provide information on insect pest populations to Cornell colleagues and other researchers in IPM. With this unique extension emphasis which combines both field and laboratory research expertise, our extension program is an integrative component with other extension programs at Cornell to identify and monitor invasive insect pests, identify insect pests that are unidentifiable using conventional morphological criteria with field specimens (such as morphologically damaged specimens and immature stages of many insect species) and differentiate insect populations using molecular techniques.
