Results from the final General Additive Models (GAMs) for the flight activity of H. ligniperda.

GAMs have a parametric component and a smoothing part, hence the distinction between parametric coefficients and the smoothing terms. s() = smooth term for a continuous variable, SE = standard error of the estimate, t = t-statistic, P = P-value, edf = estimated degrees of freedom, F = F-statistic. Wdspd = Wind speed, PAR = Photon flux density, and RH = Relative humidity. Significant values are denoted with P <0.05 = *, P <0.01 = **, P <0.001 = ***.
