Estimative of Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) development time with non linear models
Neotropical Entomology 33 (2), 141-148
Abstract: The objective of this study was to evaluate the precision of the non linear models of Davidson (1942, 1944), Stinner et al. (1974), Sharpe and DeMichele (1977), and Lactin et al. (1995) to describe relationship between developmental rate of different stages of Podisus nigrispinus (Dallas) and temperature. Lower values of R² for the models of Davidson (0.1593 to 0.2672, and 0.1406 to 0.2804 for males and females, respectively) and of Stinner et al. (0.2136 to 0.6389, and 0.1417 to 0.3045 for males and females, respectively) showed that these models were not adequate to estimate developmental rate of P. nigrispinus as function of temperature. However, high values of R² for the models of Sharpe and DeMichele (0.9226 to 0.9893, and 0.8818 to 0.9914 for males and females, respectively), and of Lactin et al. (0.9485 to 0:9997, and 0.8961 to 0.9997 for males and females, respectively) showed that these models, are suitable to estimate developmental rate of P. nigrispinus as function of temperature. Females of P. nigrispinus showed high tolerance to high temperature which is represented by high values of H_H for immature stages of this insect obtained with the Sharpe and DeMichele model. According to this model females of P. nigrispinus present thermal stress at 33.3°C, which indicates that maximum thermal estimated by this model was close to the real one.
