Lottka-Volterra predator-prey model:
where
Pb = pest bug population
Pbm = maximum pest bug population, i.e. carrying capacity
μ = ideal growth rate
for pest bugs
Kw = killer
wasp population
k = predation constant for
pest bugs (how fast they decline based on wasp population)
k’ = predation constant for killer wasps (how fast they
increase based on pest bug population)
