Sampling Variation

AbstractA study of sampling variation in the white grubs Phyllophaga fusca Froelick and P. anxia LeConte in a permanent meadow showed that inter-plot differences occurred in 70% of the samples. Block differences were rarely significant. For all stages, the most appropriate sample unit was a 1 ft cube of soil and sod. The number of samples required was inversely proportional to population density; this relationship was graphed for three levels of sampling precision.
