Effects of Environmental Temperature on Capnodis tenebrionis Adult Phenology
Table 1
The parameter estimate of a nonlinear model describing Capnodis tenebrionis adult phenology. The comparison with the linear regression for each year of the observed cumulative percentage versus the predicted values with the global logistic equation. Degree-day values at 50% of cumulative adults calculated with ordinary least squares regression for Capnodis tenebrionis adults (overwintering and emerging adults of the year) for two different Mediterranean areas (S: Sicily; C: Calabria).
