Welcome to the most recent Southern Idaho Aphid Monitoring Network update. In collaboration with the Idaho Crop Improvement Association, Idaho Potato Commission, agronomists and potato growers, the network monitors over 35 sites across Southern Idaho. Our goal is to track aphid movements in Southern Idaho to help inform decisions regarding aphid-borne plant virus management. If you are looking for the Northern Idaho Aphid Monitoring Network (the Legume Virus Project) click here.
For the Southern Idaho Aphid Monitoring Network, we use the standard yellow bucket trap (pan trap) (Figure 1) to collect flying insects. These traps are checked weekly and number of aphids are counted. Crude identification of the types of aphids observed at each location is underway and may be available in the future. For more information on yellow pan trapping, check out this great resource here. In addition to pan traps, we also incorporate privately owned and operated suction traps at selected sites (Figure 2).
