Development response of Spodoptera exigua to eight constant temperatures: Linear and nonlinear modeling

Temperature-dependent development of Lista haraldusalis (Walker) (Lepidoptera: Pyralidae) on Platycarya strobilacea

“…However, the linear models underestimated these two parameters (Howe, 1965;Karimi-Malati et al 2014), the linear relationship was only applicable to a temperature range of 15°C to 30°C (Campbell et al, 1974;Syrett and Penman, 1981;Gilbert and Raworth, 1996;Kontodimas et al, 2004). Therefore, a linear range of 19°C-31°C was indicated by the high values of R 2 adj (0.981-0.998) in our study and the two linear models described the data adequately.…”

“…The performance of the Logan-6 model was better than the other five nonlinear models and provided satisfactory estimates of critical temperature for each immature stage and overall immature stages. SSI could estimate the intrinsic optimum temperature (T Φ ) at which the population can achieve the maximum fitness (Karimi-Malati et al 2014). In conclusion, the Logan-6 and SSI models had the best fit based on the observed relationship between developmental rate and temperature in the seven nonlinear models.…”

“…Common linear model tended to give higher T min and lower K values than the Ikemoto The survival rate of L. haraldusalis at constant temperature was analyzed using Tukey's-b test and Chi-square analysis, p b 0.05; n, number of individuals. linear model (Pakyari et al, 2011;Karimi-Malati et al 2014); the lower temperature thresholds for the immature developmental stages were 11.34°C and 11.20°C using Common and Ikemoto linear models, which are significantly lower than those of other warehouse moth species, i.e., P. interpunctella with 16.6°C-18°C, 15.35°C, and 15.2°C (Johnson et al, 1992;Subramanyam and Hagstrum, 1993;Na and Ryoo, 2000), Corcyra cephalonica with 14.75°C (Subramanyam and Hagstrum, 1993), M. sieboldii with 16.47°C (Shang et al, 2012), and P. farinalis with 14.82°C (Shang et al, 2013). The T min values for Ephestia cautella, E. calidella, E. figulilella (Subramanyam and Hagstrum, 1993), and P. interpunctella (Savov, 1973) (11.52°C, 11.95°C, 12.33°C, and 13.5°C, respectively) are close to the values obtained in the present Table 4 The fitted coefficients and measurable parameters (value ± SE) of seven nonlinear models fitting to temperature-dependent developmental rates of L. haraldusalis fed on P. strobilacea.…”

“…The lower temperature thresholds (T min ) and thermal constants (K) were predicted using linear (degree-day) models in numerous previous studies (Gilbert and Gutierrez, 1973;Campbell et al, 1974;Ikemoto and Takai, 2000;Roy et al, 2002;Arbab et al, 2008;Zahiri et al, 2010;Karimi-Malati et al 2014). However, the linear models underestimated these two parameters (Howe, 1965;Karimi-Malati et al 2014), the linear relationship was only applicable to a temperature range of 15°C to 30°C (Campbell et al, 1974;Syrett and Penman, 1981;Gilbert and Raworth, 1996;Kontodimas et al, 2004).…”

Occurrence and predictive utility of isochronal, equiproportional, and other types of development among arthropods

“…This finding is perhaps not so surprising, given that an increasing body of work in recent years has shown that many (and possibly all?) arthropod species exhibit at least some plasticity in their immature developmental pathways (Jarošík et al, 2002, 2004; Oliphant et al, 2013; Karimi-Malati et al, 2014; Quinn, 2016). Many species of decapod crustaceans (e.g., Boyd and Johnson, 1963; Hamasaki et al, 2009) and insects (e.g., Karimi-Malati et al, 2014) develop through additional or alternative stages or instars under suboptimal conditions, such as extreme temperatures, low food supply, presence of contaminants, or limited availability of substrate for settlement (Oliphant et al, 2013; Quinn, 2016 and references therein).…”
