The Cooperative Agricultural Pest Survey (CAPS) Program in Idaho Agriculture

What is the CAPS Program?
The Cooperative Agricultural Pest Survey Program (CAPS) is a federal program coordinated by the United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) Plant Protection and Quarantine (PPQ) in collaboration with state departments of agriculture, universities and similar agencies or organizations. The program monitors insects and other plant pests that threaten Idaho's agricultural and natural ecosystems, facilitating early detection, rapid response and management actions needed to address introduced pests. The CAPS Program provides funding and support for the state partners to conduct science-based surveys for exotic plant pests, diseases and weeds that have been identified as threats to U.S. agriculture.

For many years, the Idaho State Department of Agriculture (ISDA) has partnered with CAPS to protect Idaho agriculture from introductions of high risk invasive pests that could damage Idaho crops and forests and negatively impact export activities.

Every year, USDA APHIS PPQ enters into cooperative agreements with state departments of agriculture, universities and other entities. Surveys conducted through the CAPS Program in Idaho fields and other facilities represent an important line of defense against the entry and establishment of harmful plant pests and weeds.

Idaho's 2017 CAPS Surveys are:

Corn Commodity Survey
Corn is a major agronomic crop in Idaho. The USDA National Agricultural Statistical Service reported 555,000 acres of corn were planted in the state during 2015. Idaho is currently the sixth largest U.S. sweet corn producer, as well as the top production state for hybrid sweet corn seed varieties.

A complex of established insect pests on corn exists in Idaho which contains, among others, wireworms, corn rootworm, two species of armyworms, corn earworm, several types of cutworms, grasshoppers, aphids, false chinch bug, thrips and European earwig. Idaho farmers routinely inspect for these pests and treat when found at levels that may have an economic impact. Periodically; surveys for other potential pests that are not currently known to be in the state are undertaken by the Idaho State Department of Agriculture to be proactive.

During 2017, ISDA staff will be conducting a trapping survey in the following counties: Ada, Canyon, Cassia, Elmore, Gem, Gooding, Jerome, Owyhee and Twin Falls. The pests of concern are: European Corn Borer and Silver Y Moth. Traps will be set out in early June and serviced by an ISDA staff member every two weeks. ISDA will also conduct two visual surveys, one in July and the final one in August, for Cucurbit Beetle and Brown Stripe Downy Mildew.

Small Grain Commodity Survey
Wheat, which is grown in 42 of 44 Idaho counties, is a prominent crop in Idaho with its largest production areas in the eastern part of the state and the north central Palouse region. Idaho ranks ninth nationally in production of all U.S. wheat. In 2015, Idaho farmers planted approximately 1.2 million acres of wheat, which produced 60.2 million bushels of spring wheat and 57.4 million bushels of winter wheat with the combined production value of $479 million. The success of the Idaho wheat industry depends greatly on its ability to export crops to external markets.

A complex of established insect pests exists in Idaho which contains, among others, Hessian fly, wheat curl mite, a complex of six species of aphids, cereal leaf beetle, wheat stem sawfly, grasshoppers, plant bugs, wheat headworm, wheat jointworm, wheat strawworm, wheat stem maggot, wireworms and army cutworm. Idaho farmers routinely inspect for these pests and treat when found at levels that may have an economic impact. Periodically; surveys for other potential pests that are not currently known to be in the state are undertaken by the Idaho State Department of Agriculture to be proactive.

During 2017, ISDA staff will be conducting a trapping survey in the following 14 counties: Ada, Bingham, Bonneville, Canyon, Elmore, Fremont, Gooding, Jefferson, Latah, Madison, Minidoka, Owyhee, Power and Twin Falls. The pests of concern are: Egyptian Cotton Leafworm and Old World Bollworm. Traps will be set out in mid-May and serviced by an ISDA staff member every two weeks. ISDA will also conduct two visual surveys, one in June and the final one in July, for Cucurbit Beetle and Wheat Bug.

Karnal Bunt Survey
Here in the Gem State, wheat is grown in 42 of Idaho's 44 counties and is a prominent crop, with its largest production areas in the eastern part of the state and the north central Palouse region. Idaho is ranked sixth for wheat and wheat product exports. In 2015, Idaho farmers planted approximately 1.2 million acres of wheat, which produced 60.2 million bushels of spring wheat and 57.4 million bushels of winter wheat with the combined production value of $479 million.

The success of the Idaho wheat industry depends on its ability to export product to external markets, including the Asian market where a significant amount of the soft white wheat grown in the state is used in pastry and noodle making. The occurence of Karnal Bunt (KB), a seed-borne fungal disease that was first identified in India in 1931, would adversely impact the state's export markets and give rise to major regulatory actions. Karnal Bunt was detected in the United States in March 1996 in durum wheat seed by Arizona Department of Agriculture. A KB-free designation for the state of Idaho's wheat crop is critical to the industry's well-being since, a high percentage of the wheat from Idaho is shipped or distributed to export markets, and many countries have a zero tolerance for KB in import shipments.

During 2017, ISDA inspectors will be pulling 44 grain samples from the following 19 counties: Ada, Bannock, Benewah, Bonneville, Butte, Camas, Caribou, Clark, Franklin, Gem, Gooding, Idaho, Jerome, Kootenai, Latah, Minidoka, Oneida, Payette and Twin Falls. Sampling will start in mid-July and finish up by October. The samples will be tested for the presence of KB at a federal lab.
