Skeeter Buster: A Stochastic, Spatially Explicit Modeling Tool for Studying Aedes aegypti Population Replacement and Population Suppression Strategies

Figure 3

Density-dependence within a typical container (1-gallon bucket) in Skeeter Buster.

The development of a single mature egg cohort (with Neggs eggs) is tracked in a single container (10 replicated simulations). A: mortality from egg to pupa, expressed as a k-value: if Npup is the final number of surviving pupae, k = −log(Npup/Neggs). ‘+’ symbols represent the outcomes of individual simulations. Solid line is the fit of the model Npup = λ. Neggs.exp(−αNeggsβ) [26]. Dashed line represents the point at which the slope of the curve is exactly one (Neggs* = 253), marking the transition from undercompensatory (slope<1) to overcompensatory (slope>1) density-dependence (see text). B: average dry weight (in mg) of the surviving pupae.
