A detecção de Pissodes castaneus em plantios de Pinus spp. no Brasil foi registrada em 2001 no município de São José dos Ausentes, RS, e, em função dos plantios extensivos de Pinus, o inseto já se encontra distribuído em vários municípios na região Sul. O principal dano é ocasionado pelas larvas que broqueiam os ponteiros de Pinus, construindo galerias e anelando ramos e troncos em árvores jovens e adultas. As árvores atacadas apresentam copa marrom avermelhada e punturas na casca resultantes da oviposição e alimentação pelos adultos. Assim, o objetivo desta pesquisa foi determinar o período de maior ocorrência dessa praga na região madeireira do planalto norte do Estado de Santa Catarina. |

Stratification and mixing patterns of a water body are influenced by the variability of atmospheric systems, which can also modify their biogeochemical properties. The primary goal of this study was to analyze the effect of atmospheric cold fronts (CFs) on thermal stratification and water quality parameters in 4 embayments of the Furnas Hydroelectric Reservoir (FHR) (southeastern Brazil), a warm monomictic water body. A secondary goal was to evaluate the implications of this effect on the aquaculture of Nile tilapia Oreochromis niloticus (L.) in net cages. A 2 yr dataset of meteorological and water quality parameters was used to compute heat flux balance components and buoyancy frequency. These parameters were used to evaluate the influence of CFs on FHR water column stability and water quality. It was observed that the passing of CFs increased net heat loss and wind velocity, resulting in a partial mixture of surface waters with deeper layers. These changes in the physical structure of the water column altered the diel cycle of water temperature, led to a slight decrease in dissolved oxygen concentrations and pH values during the stratification period, and contributed to the increase in dilution power at the fish cultivation sites. However, following CF passages, no significant changes were observed in water quality parameters that influenced Nile tilapia cultivation in the FHR. Nevertheless, the understanding of meteorological systems and their influence on the physical and biogeochemical properties of an aquatic system is important for optimal management of aquaculture activities.
