Cotton stem borer, Eutinobothurs brasffiensis damage showed a graded distribution from the margin of the field to the middle. Infestation was considerably higher in the: border rows than in the center of the field. The study documented the beliavior of this pest during the period when it migrates from overwintering sites around the field to cotton. The results confirm fórmer observations that: the: levels of infestation are higher near humíd overwintering areas with permanent vegetation. Early planted blocks of cotton had the highest rates of infestation, often reaching 70% of plant mortality. In later plantings a 20% reduction in plant mortality was observed every time planting was delayed for ten days. The data suggest that this pest may be controlled with insecticide applications in border rows. This procedure would eliminate lhe need of chemical treatments which are environmentally unsoutid. The data also suggest that plantíng densitics of nine to tert plants per m would help to reduce: the impact of this pest on cotton yield, The relationship.between yield loss and plant mortality was assessed and the economic damage estimated.

Abstract: The aim of this study was to evaluate the variations in the stability and nutrient concentration in concentrates for piglet feeding. Five treatments were established: T1 - Control, standard concentrate formulation (SCF); T2 - PXMore5, SCF with more 5% vitamin-mineral premix (VMP); T3 - PXLess5, SCF with less 5% VMP. All these three treatments used 400kg batches in an INTECNIAL mixer; T4 - FeedMixer, SCF using a 4,000kg batch in an IMOTO mixer; T5 - PremixMixer, SCF using a 1,200kg batch in an MUYANG mixer. For each treatment, bags of 20kg were stored in three storage places for four months where room temperature and relative humidity was recorded daily. The concentration of nutrients was evaluated through centesimal and mineral analysis. The water activity of concentrate was affected by temperature and relative air humidity in different storage places. The greatest variation in concentration of crude protein, mineral residue, copper, zinc, and selenium was due to the PremixMixer treatment. Regarding the guaranteed levels, the critical value was verified only for the chrome concentration. Resumo: O objetivo deste estudo foi avaliar as variações na estabilidade e na concentração de nutrientes em concentrados para alimentação de leitões. Foram estabelecidos cinco tratamentos: T1 - controle, concentrado com formulação padrão (CFP); T2 - PXMais5, CFP com 5% a mais de vitaminas e minerais da pré-mistura (PVM); T3 - PXMenos5, CFP com 5% a menos de PVM (todos os três tratamentos utilizaram lotes de 400kg em um misturador INTECNIAL); T4 - FeedMixer, CFP usando um lote de 4.000kg em um misturador IMOTO; T5 - PremixMixer, CFP usando um lote de 1.200kg em um misturador MUYANG. Para cada tratamento, sacos de 20kg foram armazenados em três ambientes distintos por quatro meses, onde a temperatura ambiente e a umidade relativa do ar foram registradas diariamente. A concentração de nutrientes foi avaliada por meio de análises centesimal e mineral. A atividade de água do concentrado foi afetada pela temperatura e a umidade relativa do ar nos diferentes locais de armazenamento. A maior variação na concentração de proteína bruta, resíduo mineral, cobre, zinco e selênio foi devido ao tratamento ?MistPremix?. Em relação aos níveis de garantia, foi verificado valor crítico apenas para a concentração de cromo.
