# Ecology: Mosquito Life Stages A mosquito immature life-stage model. **Tracks eggs, larvae, and pupae through development and mortality, and exposes the stage composition** so you can see whether a population is egg-heavy, larval-heavy, or balanced. ## What it simulates - Three immature life stages (eggs, larvae, pupae) with stage-specific development and mortality rates. - ODE dynamics solved by Tellurium directly from the original SBML. - Stage-fraction diagnostics that always sum to 1.0.  ## Run it on the Hub 1. Open the [Turner2015 Mosquito Life-Stage Ecology Model Lab](https://hub.biosimulant.com/labs/4465424c-70ed-4f7a-a851-be77a3f44cc2) on the public Hub. 2. Click **Run**. The default scenario runs for 365 days. ## Inputs you can tune | Input | Meaning | |---|---| | `integration_step` | ODE solver step size (default 0.1 day). Smaller is more precise but slower. | | `model_path` | Relative path to the SBML file. Usually leave at the default. | Biological parameters (development rates, mortality rates, initial populations) live in the SBML file `model/data/BIOMD0000000922.xml` — edit it directly to change the biology. ## What results to expect - **Life-stage abundances**: egg, larval, and pupal counts over time. After an initial transient, the populations settle into a stable composition. - **Stage fractions**: proportion of total immature population in each stage. The default settles around 46% eggs, 39% larvae, 15% pupae. - **Summary table**: final and extremal values per stage, plus the total immature population.  ## Reference SBML wrapper for Turner et al.
