Surveying for Illinois Invasives with the CAPS Program

Gathering data on recently introduced pests. Information gathered during surveys is summarized and entered into National Agricultural Pest Information System (NAPIS) database. The NAPIS database stores and manages pest survey data that is collected by CAPS and other USDA-APHIS-PPQ programs. Maps are summarized and made available to the public through the NAPIS Pest Tracker Website. The Pest Tracker Website provides maps detailing surveys conducted around the U.S. for different invasive species as well as sharing links to pest news and information for the different states.

Also in 2013, we will be starting a new survey targeting oak pests. Over 53% of the forest cover in Illinois consists of oak and hickory – and this doesn’t include any oaks planted in urban areas. There are several invasive oak pests that if established in Illinois, would not only threaten the diversity of our natural areas, but dramatically impact our forest product industry and nursery trade. Pheromone traps will be placed targeting the oak ambrosia beetle, Egyptian cottonworm moth, rosy gypsy moth, and golden tortrix moth. We are also excited to be utilizing a new biosurveillance survey technique that monitors Cerceris wasp colonies. This buprestid-hunting wasp offers another approach to monitor for not only emerald ash borer, but also the oak splendour beetle, goldspotted oak borer, and European oak borer. The thousand cankers disease survey will continue with both walnut twig beetle trapping and monitoring the visual health of walnuts across the state.
