Background: Inflammatory bowel diseases affect mostly young patients and have a huge impact on their quality of life and growing treatment costs. Currently, there are few Brazilian studies concerning their epidemiological profile.
Objective: The aim of this study was to describe the regional clinical and epidemiological profile of these pathological conditions in Caxias do Sul, Brazil.
Article Synopsis
- The rice stalk stink bug (Tibraca limbativentris) is a significant pest for paddy rice in South America, but there is limited information on its economic impact.
- This study established economic injury levels (EILs) and economic thresholds (ETs) by analyzing the relationship between the presence of stink bugs and rice yield loss at different growth stages (V4 and R2).
- Findings showed that infestation during the V4 stage led to greater yield loss (5.91 kg/ha per insect-day/m2) compared to the R2 stage (3.16 kg/ha), highlighting that management strategies should account for the growth stage of rice and associated costs.
Root rots are a constraint for staple food crops and a long-lasting food security problem worldwide. In common beans, yield losses originating from root damage are frequently attributed to dry root rot, a disease caused by the Fusarium solani species complex. The aim of this study was to model the current potential distribution of common bean dry root rot on a global scale and to project changes based on future expectations of climate change.
