Figure 3From: Strong oviposition preference for Bt over non-Bt maize in Spodoptera frugiperda and its implications for the evolution of resistanceThe effects of random and damage-avoiding oviposition behavior and female fecundity on evolution of resistance under the sprayed refuge scenario. In these simulations the spray action threshold for refugia was 0.25 egg masses per plant, the initial frequency of resistance = 0.001 and we assumed partially dominant resistance (h = 0.1).Back to article page
