T = mean temperature, RH = mean % relative humidity, k = stage specific Erlang parameter in eqn. 1. Scripts E, L, P, A = egg, larval, pupal, and adult stages, f(x) = per capita reproductive rate per day on age (x) at 25°C, stageΔ = developmental time constant in dd above the lower threshold for a stage, stageΔx = (stage developmental time multiplied by stage developmental rate), 0 ≤ F(T or RH, min, max) ≤1 is a symmetrical function between min and max values equal 1 at (max + min)/2). ϕRH and ϕT are scalars for reproduction, and μstage is the temperature-dependent stage mortality rate. Fits for all BDFs had R2>0.85.
