For T. infestans in the Amamá core under sustained vector surveillance and control, in (A) surveys 1 (October 1993) to 7 (May 1997) and (B) surveys 8 (November 1997) to 13 (October 2002), TL described the relationship between y = log₁₀ v and x = log₁₀ m of the relative abundance of T. infestans. Each point represents the mean and variance of bug abundance for one habitat at one survey. The solid straight lines are fitted by least-squares regression to the data from each survey separately. (C) Values of the parameters a (solid gray line) and b (dashed black line) of TL at each of the 13 surveys. (D) Slope b as a function of the range (maximum log₁₀ mean minus minimum log₁₀ mean) of the number of bugs. The greater the range, the smaller the variability in b. Key as in Fig 2.
