The resistance of rice stalk stink bug, Tibraca limbativentris Stal 1860 (Hemiptera: Pentatomidae) to five insecticides was investigated in the present study. The tested insecticides were bifenthrin, carbosulfan, etophenprox, λ-cyhalothrin, and thiametoxam. The five field-collected populations of rice stalk stink bugs from Luis Alves-GO, Flores de Goiás-GO, Formoso do Araguaia-TO, Lagoa da Confusão-TO and Itajaí-SC were investigated in relation the insecticide resistance occurrence. A further Santo Antônio de Goiás population, from natural environment was used as standard-population of susceptibility. Insects of these populations were submitted to discriminating concentrations (LC95s) with objective to determine the frequences of individuals resistants. The insects population from Formoso do Araguaia were the most resistant to all tested insecticides. The mortality values observed in this population were 76%, 86%, 72%, 80%, and 80% for carbosulfan, bifenthrin, etofenprox, λ-cyhalothrin, and thiamethoxam, respectively. The frequencies of resistant individuals ranged from 9% a 23% and were classified as moderate. The more expressive values of the resistance rate (RR) were found to the insecticide thiamethoxan 17-fold in the population of Formoso do Araguaia and 12-fold to the Luís Alves population. This first findings about insecticide resistance in T. limbativentris shows the seriousness of the problem in the region and suggests the possible occurrence of cross-selection in this species, confering insecticide resistance to one or more products of different groups. These results are usefuls as information to integrated pest management (IPM) in the regions producers of flooded rice in Brazil, as technical guidance to rice farmers and open news perspectives of investigation in this research area.

This chapter presents and discusses the avulsive nature of the Pantanal rivers and shows how the ever-changing drainage network influences the surface hydrology and ecology. Besides, the systemic portrait here outlined provides new insights concerning the Pantanal hydrodynamics, in its particularities and as a whole system. A simple model of the avulsion process is illustrated, and several realistic examples of the processes leading to river avulsions are shown and discussed. The north-to-south flood-pulse wave due to the presence of bottlenecks is further described in detail. This systemic approach allows identifying that the fluvial ?avulsive and bottleneck? dynamics seasonally affects both local and regional ecohydrological processes. Moreover, it shows that avulsive processes are commonplace in Pantanal, and changes in land use, particularly in river headwaters in the highlands, accelerate the avulsions, making the sustainable use of the Pantanal lowland areas difficult. |
