Mosquito survival and dispersal is described by a demographic matrix, denoted \(\Omega.\) It is computed using several parameters:
gmortality rate
sigmapatch emigration
muemigration-related loss
Ka dispersal matrix
The matrix is computed as:
$$ \Omega = \mbox{diag} \left( g + \sigma \mu \right) - K \cdot \mbox{diag} \left( \sigma \left(1-\mu\right) \right) $$
In delay differential equations with a constant EIP (\(\tau\)), survival and dispersal through the EIP is given by: $$ \Upsilon = e^{-\Omega \tau} $$
