Chrysomya megacephala (F.), a exemplo de muitas outras moscas-varejeiras, utiliza recursos discretos e efêmeros para alimentação e oviposição, tais como carcaças em decomposição. O contexto espacial em que ocorre competição por alimento em C. megacephala caracteriza-se por duas populações: indivíduos adultos dispersando-se e imaturos que são depositados nos substratos pelas fêmeas adultas. O objetivo do estudo foi investigar aspectos da bionomia associados com competição larval por alimento em populações experimentais de C. megacephala, incluindo comportamento de ovipostura e peso mínimo necessário para pupação. Os resultados indicaram que fêmeas depositam parte de seus ovos produzidos, contrastando com estudos anteriores que consideraram apenas ovipostura completa. A percentagem de eclosão de larvas foi alta (90 %) e o peso mínimo necessário para pupação situou-se entre 30 e 32 mg.

The experiment aimed to verify the effect of maturation stage on the quality of minimally processed peaches. Fruits were used in two stages of maturity, on time corresponding to the background color yellow-green, and mature, which corresponds completely to the background color yellow. The minimum process consisted of washing, sanitizing, enzyme peel, cut lengthwise and removed the stone fruits. Halves obtained were immersed in water chlorinated to 10 mg L-1 of water and left on standing to drain the excess liquid. Afterwards, it was proceeded the packaging of the halves in containers of polyethylene terephthalate (PET) and with transparent lid, and the storage at 3 ± 2 ° C and RH = 65% for 12 days, with assessments every three days. The variables evaluated were appearance, weight loss, firmness, soluble solids, titratable acidity, soluble and reduced sugars, ascorbic acid, total and soluble pectin, coloring and activity of polyphenoloxidase. The storage of minimally processed peaches 'Aurora-1' mature harvested was limited mainly by the loss of freshness and firmness, and because they have darker appearance, and lower levels of reduced sugars and ascorbic acid. Peaches 'Aurora-1', harvested at the maturity stage on time, had better quality and longer duration of their minimally processed products.
Influência da seleção dos estágios incrementais sobre a intensidade de lactato mínimo: Estudo piloto

The purposes of this study were to assess the influence of stage selection from the incremental phase and the use of peak lactate after hyperlactatemia induction on the determination of the lactate minimum intensity (iLACmin). Twelve moderately active university students (23±5 years, 78.3±14.1 kg, 175.3±5.1 cm) performed a maximal incremental test to determine the respiratory compensation point (RCP) (initial intensity at 70 W and increments of 17.5 W every 2 minutes) and a lactate minimum test (induction with the Wingate test, the incremental test started at 30 W below RCP with increments of 10 W every 3 minutes) on a cycle ergometer. The iLACmin was determined using second order polynomial adjustment applying five exercise stage selection: 1) using all stages (iLACmin P); 2) using all stages below and two stages above iLACminP(iLACminA); 3) using two stages below and all stages above iLACminP(iLACminB); 4) using the largest and same possible number of stages below and above the iLACminP(iLACminI); 5) using all stages and peak lactate after hyperlactatemia induction (iLACminD). No differences were found between the iLACminP(138.2±30.2 W), iLACminA(139.1±29.1 W), iLACminB(135.3±14.2 W), iLACminI(138.6±20.5 W) and iLACmiD(136.7±28.5 W) protocols, and a high level of agreement between these intensities and iLACminPwas observed. Oxygen uptake, heart rate, rating of perceived exertion and lactate corresponding to these intensities was not different and was strongly correlated. However, the iLACminBpresented the lowest success rate (66.7%). In conclusion, stage selection did not influence the determination of iLACmin but modified the success rate. © Creative Commom.
