UI potato psyllid scouting program started
The University of Idaho, in collaboration with Miller Research and several crop consultants across the state, has initiated a scouting program that covers commercial potato fields throughout southern Idaho. The project is funded in part by ISDA. The primary means of sampling psyllids will be by the use of yellow sticky cards, although vacuum samples and leaf samples are being taken from some fields as well. The first traps were deployed during the week of May 13; thus far, no potato psyllids have been found in any samples. Details of the monitoring program and results of monitoring efforts (by county) will be available soon.
Western Cherry Fruit Fly
The following information was submitted to the PestAlert Network by Jodie Ellis, Program Manager with ISDA.
"On Thursday, May 23rd, seven adult Western cherry fruit flies were found on an ISDA trap near Caldwell (Sunnyslope Road) in Canyon County. If growers observe that their cherries are yellowing, they may wish to start control measures for this pest before oviposition in the fruit begins. Pesticides commonly used for Western cherry fruit fly are carbaryl, malathion, spinosad, Delegate, Imidan, or Asan. Always use pesticides according to label recommendations."

cereal leaf beetle
Last week I found cereal leaf beetle larvae in winter wheat at the UI Parma R and E Center. There were not many, but they are out there. You may want to keep a look out for these pests, especially as spring grains begin to increase in foliage, since they are the preferred host.
colorado potato beetle
Colorado potato beetles were found in volunteer potatoes late last week in the Parma area. So far, only overwintered adults have been observed, and they will do little damage to potatoes. Scouting should begin soon for eggs and for larvae, which can cause considerable damage to commercial potatoes.
