[Protease inhibitors] extracted from Acacia [food bodies] were biologically active, as they effectively reduced the trypsin-like and elastase-like proteolytic activity in the guts of seed-feeding beetles (Prostephanus truncatus and Zabrotes subfasciatus), which were used as non-adapted herbivores representing potential exploiters. By contrast, the legitimate mutu- alistic consumers maintained high proteolytic activity dominated by chymotrypsin 1, which was insensitive to the FB PIs.

We have highlighted what we believe are limitations to genetic risk prediction as well as the most important pitfalls to befall researchers, and we have discussed how these can be avoided. Most problems occur in the validation stage, when data are not fully independent from those in the dis- covery phase, but care is also needed to ensure that the discovery and validation samples are representative of the popula- tion in which the predictor will be applied.
