In the Lactin and Logan models, [T.sub.opt] can be estimated as the parameter value for which the first derivative equals zero.
In general, all the models gave a good fit with [r.sup.2] values above 0.85, except for the modified Lactin model, where the [r.sup.2] value was 0.53.
All nonlinear models gave a good fit with [r.sup.2] values above 0.87 with the exception of the modified Lactin model, which gave a poor fit with an [r.sup.2] value of 0.34.
In contrast, the Lactin model gave the best fit for temperature-dependent development of X.
Temperature can also determine the number of times an individual molts, which alters both time-to-adult and adult body size (Willott & hassall 1998; Lactin & Johnson 1998a; Maeno & Tanaka 2010).
Because temperature strongly influences their biology, grasshoppers have evolved mechanisms to regulate their temperature (Chappell & Whitman 1990; Lactin & Johnson 1996; Miller et al.
For example, the effect of temperature may change over time (Whitman 2009) and among instars, populations, and species (Whitman 1987; Lactin & Johnson 1995; Telfer & hassall 1999), and are difficult to interpret (Shi & Ge 2010).
A novel antiproliferative and antifungal lactin from Amaranthus viridis Linn seeds.
(1976) exp([rho][T.sub.m] - [T.sub.m] - T/[delta])] Lactin r = exp([rho]T) = Lactin et al.
where r(T) is the rate of development, T is the temperature and, Tmax (the upper temperature threshold), [rho], [DELTA], and [lambda] are fitted parameters (Lactin et al.
Lactin model curves were fit by iterative nonlinear regression (PROC NLIN, SAS Institute 2003).
Parameter estimates and statistics from the Lactin regressions are reported in Table 4.
