The objective of this study was to assess the stink bug economic threshold for soybean integrated pest management decisions. For this purpose, a replicated experiment was implement in a commercial soybean crop located in Arapongas, Parana State, Brazil, during two crop seasons: 2010/2011 and 2011/12. Treatments consisted of different stink bug densities triggering the application of insecticides, ¼ of the economic threshold (ET) (= 0.5 stink bugs m?1) and ET (= 2 stink bugs m?1), and without applying an insecticide (control). The stink bugs were quantified weekly and all specimens were identified to the species level. At harvest, yield and quality of the seeds were also measured. In all crops, Euschistus heros was the most abundant species. The highest yield and percentage of viable seeds were found in the 'BMX Power RR? cultivar (indeterminate growth cultivar), indicating a better seed quality. At the end of the experiment, there was no observed difference in yield between different stink bug management thresholds, indicating the effectiveness of the control when adopting ET. This study demonstrates that decreasing the economic threshold increased the number of required insecticide applications, but did not increase yield or bean quality neither the net income when an economic analysis was performed. |

Few studies have addressed the diversity of cultivable fungi from marine sediments, especially those from Antarctica. In the present study, we evaluated the presence and distribution of cultivable fungi in marine core sediments obtained from 100, 500, 700 and 1,100 m below the Antarctic Ocean surface. Fifty-two fungal isolates were identified as Penicillium solitum by their physiological and morphological characteristics, and the identity of 12 representative isolates was further confirmed by sequencing of the ITS1-5.8S-ITS2 and b-tubulin genes. P. solitum displayed high sequence similarity to Penicillium taxa that have been described from other marine habitats. Conidial germination of P. solitum occurred at low temperatures and high salinities. In addition, P. solitum displayed extracellular amylasic and esterasic activities. The isolation of P. solitum from marine sediments in Antarctica and its survival at low temperatures and high salt concentrationssuggest that it is adapted to the cold and halophilic environment of the Antarctic oceans. Because P. Solitum produces extracellular enzymes, it is an interesting eukaryotic model for the study of structure?function relationships during enzymatic biocatalysis and biotransformation under extreme conditions. Marine sediments from Antarctica may represent a unique source for obtaining extremophilic fungi. New studies using different culture media, temperatures ranges and pressure conditions as well as metagenomic techniques can assist in understanding the extremophilic fungal communities in marine sediments across the Antarctic Ocean.
