sick white pine

Asked May 16, 2014, 8:33 AM EDT

Hello -- I have two big white pines. One has almost died (of a "sap beetle") and the other has a lot of brown needles but not sap running down. How can I send in a small branch to have it analyzed for disease or pests? I live in Iowa City. Thank you. Alan MacVey
