Abstract
Gini’s (1912) coefficient of concentration is recommended as the basis for a significance test to compare the dispersions of two negative binomial populations. The data are assumed to be quadrat counts, and the jackknife technique is used to estimate standard error. Simulation studies indicate that as few as 20 quadrats may be adequate for some negative binomial populations. Application is made to the comparison of dispersions of the adult southern green stinkbug (Nezara Viridula) on three row crops.
