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.

The aim of this study was to correlate the chemical control efficacy in post-emergence of Brachiaria decumbens Stapf. (signal grass) and Brachiaria plantaginea Hitchc. (alexandergrass) through ACCase-inhibitor enzyme herbicide application in function of the stage of development of the plant in order to contribute to the chemical management of these weed species. B. decumbens and B. plantaginea were sown in plastic pots filled with soil and kept in a greenhouse. For chemical control evaluation, the following herbicides were tested (g ha-1): fluazifop-p-butyl at 150, haloxyfop-methyl at 50, and sethoxydim at 230. The herbicides were applied in all three plant development phases: stage 1 (plants presenting 4-6 leaves at 15 days after emergence), stage 2 (plants presenting 3-4 tillers at 23 days after emergence), and stage 3 (adult plants in the beginning of flowering at 48 days after emergence). Evaluations were done at 4, 7, 10, 14, 17, 21, 24, and 28 days after herbicide application. The developmental stage of the two Brachiaria species was instrumental in the efficiency of the control provided by different herbicides. Sethoxydim was the most efficient herbicide in controlling Brachiaria species in the three evaluated development stages.
