Allsopp, P.G. 1991a Binomial sequential sampling of adult Saccharicoccus sacchari on sugarcane.. Entomologia Experimentalis et Applicata 60: 213-218.

Notes: The between-stalk dispersion characteristics of adults of the pink sugarcane mealybug were determined in southern Queensland; Iwao's patchiness regression was inappropriate to describe the relationship between mean and variance; Taylor's power law indicated that adults were aggregated, especially at the beginning and end of the ratoon growth period; binomial data were modelled by the Nachman model; the model of Grout and two models of Wilson & Room were inappropriate to describe the relationship bhetween proportion of stalks infested and mean numbers of adults per stalk; relationships to determine sample sizes for fixed levels of precision and binomial fixed-precision-level stop lines are developed for different sampling times using Taylor's power law and Nachman's equation.
