This implements differential equation model for aquatic mosquito ecology. The equations have been modified slightly from a version published by Smith DL, et al. (2013); this version includes delayed maturation i in response to mean crowding.

Variables:

  • \(L\): the density of mosquito larvae in each habitat

Parameters and Terms:

  • \(\eta\) or eta: egg deposition rate (from F_eggs)

  • \(\psi\) or psi: maturation rate

  • \(\xi\) or xi: delayed maturation parameter in response to mean crowding

  • \(\phi\) or phi: density-independent death rate

  • \(\theta\) or theta: the slope of the mortality rate in response to mean crowding

Dynamics:

$$dL/dt = \eta - (\psi\;e^{-\xi L} + \phi + \theta L)L$$

Per-capita mortality is thus \(\phi + \theta L\), and the emergence rate of adult mosquitoes is \(\psi e^{-\xi L} L \)
