An Improved Saratoga Spittlebug Nymphal Appraisal Survey
Abstract:The traditional Saratoga spittlebug nymphal appraisal survey was made more accurate and more efficient by: (1) restricting the time for sampling; (2) sampling only high risk acreage stands; (3) tallying the nymphs by using percentage of sample-frames infested; and (4) providing a broader range of decision options for the forest manager. The new survey reduced sampling time by one-third to one-half that of the traditional method. North. J. Appl. For. 7:83-86, June 1990.
