Beating Tray:  You can purchase one or make your own.  Cut a black or white cloth and sew the corner edges down to make a pocket.  Bind two sticks or rods to make an “x”, and wrap the cloth corners into the edges of each stick.  Alternatively, wrap a cloth tightly around an old window frame and attach a stick or rod to hold it.  (Nymphs are easiest to see on black cloth.)2.  Beating Stick:  Use a stiff rubber hose or wrap a stick or PVC pipe with padding and duct tape.3.  16 - 20x magnifying lens.  Sampling Procedure:1.  Select at least 10 trees to sample in blocks of 5 acres or less and at least 20 trees in blocks of larger than 5 acres.2.  Hold beating tray under one limb on each tree and hit limb three times with the beating stick.  Choose limbs that have the most flower clusters. 3.  Tip tray slightly so that larger debris falls away.4.  Count all the campylomma nymphs that fall onto the tray and record for each tree.  Treatment Thresholds:Pink to bloom, 0.1 nymphs per tray on ‘Golden Delicious’ and 1.0 nymph per tray on ‘Red Delicious’.Bloom to petal fall, 0.2 nymphs per tray on ‘Golden Deli-cious’ and 1.75 nymphs per tray on ‘Red Delicious’.Utah State University is committed to providing an environment free from harassment and other forms of illegal discrimination based on race, color, religion, sex, national origin, age (40 and older), disability, and veteran’s status.
