  1. The models are based on a logistic growth function \(y = \frac{Asym}{{1 + e^{{\frac{xmid - x}{{scal}}}} }}\). y stands for the number of larvae, x is the number of days after setup, and the parameters estimated by the models are the asymptote (Asym), the timing of the growth (xmid) and the rate of the growth (scal)
