σ Maximum per capita migration rate \( \frac{individual}{day\cdot individual} \) 0.1 -

  1. σ and η (included in equation 4) were approximated using a simple assumption about the per-capita migration rate of insects in a patch, which also depends on the number of nymphs and adults. L is a matrix that represents which connections, with origin j and destiny i, have light at patch i. Each L ji takes a binary value 0 (no light) or 1 (light). Accordingly, D is a matrix that represents the distance between connections and D ji is the Euclidean distance in meters between patch j and i
