Dynamic model and simulation
Host and parasitoid emergence counts were used to parameterize a
stochastic age-structured Nicholson-Bailey model. We calculated the
number of generations host and parasitoid populations persisted before
going extinct and statistically compared which factors promoted the
probability of host-parasitoid persistence. The methods used for
developing the mathematical model, fitting with data, simulating
host-parasitoid interactions across generations, and statistical
analyses are described in SI Materials and Methods .
