Both larvae and adults are harmless. Once an orchard is infested, it is difficult to prevent increase and spread of the beetle to nearby trees. Samples collected from an infested sweet cherry orchard in Utah found a majority of smaller larvae (< 1-1/2 inches in length) in roots (72%) and a predominance of larger larvae (1-1/2 3 inches) in crowns (59%) of trees (the crown is the region of the trunk at or near the soil surface where roots transition into the above-ground stem) . Systemic materials, such as imidacloprid (Admire, Merit, and Bayer Advanced Garden Tree and Shrub Insect Control) may be options, but recent research indicated that this material may be effective only on the younger larvae on roots, and not against the older larvae in the crown or lower trunk. The California Prionus beetle, Prionus californicus, can be as large as two to two-and-a-half inches. The feeding injury is often associated with rot and decay, particularly in wet soils.
