Use of Taylor's Power Law in examining the spatial distribution of free-living Boophilus microplus (Acari: Ixodidae) larvae in pastures in Puerto Rico.
Taylor's power law (y = amb) was used to analyze the spatial pattern of Boophilus microplus (Canestrini) larvae in tropical pastures. The index of aggregation b was 2.75 and showed that larvae were highly aggregated. The b-values differed significantly among certain pastures (LSD, P less than 0.05), and pasture type and use could have contributed to differences in b. The use of Taylor's power law to adjust for sampling inconsistencies that occur in tropical pastures where regimented sampling cannot always be followed is discussed.
