Abstract
Taylor’s Power Law was performed on mean and variance estimates of eggs and viviparae of walnut aphids, Chromaphis juglandicola (Kaltenbach). Highly significant correlation coefficients suggested that Taylor’s Power Law fit the data well. Means and estimated variances of walnut aphid eggs and viviparae were used to develop proportion-infested relationships and generate optimal numerical and binomial sample size curves for these life stages of the aphid. Information presented in this paper should help improve accuracy and efficiency in sampling of the walnut aphid in the future.This publication has 4 references indexed in Scilit:
