posted on 2023-05-16, 19:26 authored by Walker, PW, Allsopp, PGAll models indicated that the cysts were aggregated in distribution. Taylor's power law generally gave better or equivalent fits to the population dispersion parameters than did Iwao's regression model. Relationships to determine sample sizes for fixed levels of precision and fixed-precision-level stop lines for sequential sampling were developed for each margarodid genus. There were functional relationships between the variance and mean of untransformed population counts for all margarodids and crop ages, and the suitability of three transformation functions is assessed. -from Authors
