Methods are proposed as a contribution towards the formalization of an approach to the selection and introduction of entomophagous insects. Once the critical resources necessary for the reproduction and survival of a predator or parasitoid have been identified, sites are arranged to sample these insects in different grades of the same critical factor. These grades of a resource may be ranked, and organized on gradients, or unranked, but in both cases the range of samples represents a resource set. The entomophagous insect distributions on these sets are analyzed and quantified by formulae that show the breadth of a species distribution, the similarity between distributions, and the interaction species will experience on each of the resource sets. These calculations can assist in selecting the best species for introduction into an area with a known species composition and distribution.
