Abstract

Co-occurrence of cotton, maize and soybean in spatio-temporal dimensions (called cross-contamination) may be important for maintenance of multiple polyphagous pests during crop time or postharvest. In these conditions, information focused on movement strategies and competition between immatures is scarce. Understanding when, how, where and why insects move in the larval stage as way for exploitation and survival in different patches is an important question in studies emphasizing evolutionary dynamics of pre-adapted individual to genetically modified technologies. Taking into account the possibility of interspecific and intraspecific competition, involving Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) and Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) the mathematical structure of game theory may be useful to describe the decision-making dilemma between dispersal or stay in the plant. This mathematical approach will also be useful to evaluate the consequences of competitive behavior for maintenance and propagation of allele(s) conferring resistance to transgenic technology for both pest species. In this sense, we intend to analyze how the simultaneous occurrence of cotton, maize and soybean plants expressing or not genes of Bacillus thurigiensis (Bt) (Berliner), affect the larval movement dynamics and competition of S. frugiperda and H. armigera. Subsequently, we intend to simulate these ecological interactions with game theory in order to understand how the interactions influence the dynamics of local adaptation in scenarios with pure and cross contamination. With association to the Thematic Project (Process: 14/16609-7), this proposal aims to serve as a basis to guide strategies of resistance management to make possible proactive action of agronomic practices with the objective of delaying in isolation or simultaneously the resistance evolution in relevant pest species.
