Abstract/Contents: | "Four of 26 St. Augustinegrass locations found to harbor lance nematodes were sampled using single 2.2-cm-d cores. These data were used to approximate the number of samples necessary to estimate a lance nematode population with a confidence interval of 20% of the population mean. A single site, representing a worse-case scenario, was then chosen for intensive study. The site was divided into horizontal quadrats on the basis of visual cues and into vertical quadrats by depth. Each quadrat was sampled proportionally in relation to size. Two sampling units were used: the standard 2.2-cm-d core was nested within a 10-cm-d core. A total of 258 samples (43 locations × 3 depths) were processed by a sieving-centrifugation technique with occasional processing checks. Lance nematodes were counted by life-stage. All steps were timed and the optimal sampling strategy determined using time as a cost factor. Sample types and depths differed greatly in their costs; for equal population estimates, 2.2-cm-d cores were more costefficient than 10-cm-d cores." |
