The growing interest in the production of red sparkling wines has encouraged research into their chemical composition and the contributions of these characteristics to enhance their quality and complexity. This study aimed to evaluate a novel method for winemaking red sparkling wines, using pre-fermentation cold maceration of the grapes. The impact of pre-fermentation cold maceration time (at 8ºC) on the volatile profile of ‘Syrah’ red sparkling wine elaborated by the traditional method was assessed during the autolysis period (3 and 18 months). The following treatments were tested: NM: without cold maceration; M24: maceration for 24 hours; M72: maceration for 72 hours. The volatile compounds were extracted and identified by HS-SPME-GC/FID-GC/MS. Sixty-five volatile compounds were identified and semi-quantified in the samples, including aldehydes, terpenes, ketones, acids, alcohols, and esters, with the latter three classes being more abundant, notably the esters. The use of cold maceration promoted higher concentrations of esters such as ethyl octanoate, ethyl decanoate, and ethyl hexanoate, regardless of the autolysis time of the red sparkling wines. Furthermore, esters such as isoamyl acetate, hexyl acetate, and phenethyl acetate decreased their concentrations after 18 months of autolysis. Additionally, twenty-one compounds presented concentrations above the odor threshold, and the hierarchical cluster and heat map analysis showed that red sparkling wines produced using pre-fermentation cold maceration and 3 months of autolysis stood out in these compounds. In this way, these sparkling wines may potentially exhibit greater aromatic intensity. To assess the accuracy of these findings, a sensory evaluation should be considered to complement this study about the impact of winemaking practices on the quality of red sparkling wines.

Abstract - The objective of this work was to evaluate the circadian feeding rhythm of the green-belly stink bug (Dichelops melacanthus) on corn (Zea mays), and to correlate it with meteorological parameters. The experiments were conducted in corn fields in the first (summer) and second (fall) crop seasons, in the municipality of Chapecó, in the state of Santa Catarina, Brazil. Plants in the V3 and V5 stages were covered with cages and infested with adults of D. melacanthus. After 24 hours of acclimation, the number of insects feeding on the plant stem was counted every three hours (at 6:00, 9:00, 12:00, 15:00, 18:00, 21:00, and 0:00 h). At night, a red led flashlight was used to visualize the insects without interfering with their behavior. Meteorological parameters were monitored and correlated to the number of insects feeding on the plants. In the first and second crop seasons, the number of insects feeding on the corn stem differed among evaluation times, with peak in the afternoon, in the evening, and at night. Few insects were found feeding at 6:00 and 9:00 h. There was a positive correlation between air temperature and feeding in both seasons. In milder temperature regions, the preferred feeding time of D. melacanthus on corn is during the afternoon, evening, and night hours, which should be taken into account for a precise management of this insect. Resumo - O objetivo deste trabalho foi avaliar o ritmo circadiano de alimentação do percevejo barriga-verde (Dichelops melacanthus) em milho (Zea mays), e correlacionar esse comportamento com parâmetros meteorológicos. Os experimentos foram realizados em cultivos de milho de primeira (verão) e segunda safras (outono), no município de Chapecó, no estado de Santa Catarina, Brasil. Para isso, plantas nos estágios V3 e V5 foram cobertas por gaiolas e infestadas com adultos de D. melacanthus. Após 24 horas de aclimatização, o número de insetos que se alimentava no colmo das plantas foi mensurado a cada três horas (às 6:00, 9:00, 12:00, 15:00, 18:00, 21:00 e 0:00 h). Para avaliações noturnas, utilizou-se uma lanterna com led vermelho, para visualizar os insetos sem interferir em seu comportamento. Parâmetros meteorológicos foram monitorados e correlacionados com o número de insetos que se alimentava nas plantas. Nas primeira e segunda safras, o número de insetos que se alimentava nos colmos de milho diferiu entre os horários avaliados, com maior abundância à tarde e à noite. Poucos insetos foram observados alimentando-se às 6:00 e 9:00 h. Houve correlação positiva entre a temperatura do ar e a alimentação, em ambas as safras. Em regiões de clima mais ameno, o período preferido para alimentação de D.melacanthus em milho é nas horas da tarde e da noite, o que deve ser levado em consideração para um manejo eficiente desse inseto.
