One of the factors that affect the control of brown - roots environmental bedbug is the wide availability of plant species. Thus, this study aimed to evaluate the migration of nymphs of the brown - roots between plant species of economic importance and invasive stinkbug. Eight species of plants have been established in a set formed by eight circular PVC containers, connected symmetrically with free communication to a central circular container. The experiment was arranged in a completely randomized design and consisted of eight treatments and six replications. The test evaluations were performed on 15o , 30o , 45o and 60o days after the release of the nymphs, by counting the insects that migrated to the roots of different plants. It was observed that by the 30o day of early release nymphs, no significant differences (P < 0,05) in the choices nymph by plants. B. alata at 15 days of initial release and B. alata and grass-dictyoneura at 30 days were plants that had higher migration. All counts were carried out on 45o and 60o days, the migration of U. brizantha cv. Marandu presented significantly higher than all other species tested plants nymphs.
