                                    Citation: Manoukis, N., Hall, B., Geib, S.M. 2014. A computer model of insect traps in a landscape. Scientific Reports. 4:7015.Interpretive Summary: This paper describes a novel model representing insect traps at a landscape level. The model is based on a mathematical function relating distance from a trap to probability of capture, applied across many traps in specific locations. The model may be particularly useful for studying detection networks of diverse invasive pest species.
                                Technical Abstract: Attractant-based trap networks are important elements of invasive insect detection, pest control, and basic research programs. We present a landscape-level spatially explicit model of trap networks that incorporates variable attractiveness of traps and a movement model for insect dispersion. We describe the model and validate its behavior using field trap data for networks targeting two species, Ceratitis capitata and Anoplophora glabripennis. Our model will assist efforts to optimize trap networks by 1) introducing an accessible and realistic mathematical characterization of the operation of a single trap that lends itself easily to parametrization via field experiments and 2) allowing direct quantification and comparison of sensitivity between trap networks. Results from the two case studies indicate that the relationship between number of traps and their spatial distribution and capture probability is qualitatively dependent on the attractiveness of the traps, a result with important practical consequences.
