A common technique used to control phorid fly infestations on stingless bee?s nests is the use of traps with commercial vinegars, especially the red wine vinegar, which is stated to be more efficient than the white wine vinegar. However, the claims on its greater efficacy are only circumstantial, not based on experiments. Thus, the aim of this work was to test the efficacy of traps composed of red wine or white wine commercial vinegars on the attractiveness of adult Pseudohypocera kerteszi Enderlein (Diptera Phoridae) females that infested colonies of Melipona fasciculata Smith, and Melipona seminigra Friese. The comparisons were made by placing one trap of red wine vinegar and other of white wine vinegar in infested colonies of the studied species for a week to check for possible differences in their attractiveness on phorids. We also tested the possibility that traps could attract phorid flies from outside the nests, thus potentially increasing an infestation. This was tested by placing traps of red wine vinegar in empty hives in the meliponary, thus eliminating bee?s odours and food stores as factors that could attract phorid flies. There was no difference on the attractiveness of traps composed of red wine or white wine vinegars (Wilcoxon matched-pairs test), and traps did not any attract phorid flies from the outside to the interior of hives. Thus, the red wine and white wine vinegars can be equally used to capture phorid flies that invade nests of stingless bees, and they do not attract flies from outside the nests, thus not increasing infestations. The other objective of this work was to correlate the body size, particularly the maximum head width of the captured phorids and their abundance, with the monthly rainfall levels during the experimental period. We noticed an increase of abundance of phorid flies on the rainy periods, but there was no correlation with body size, which we suggest to be a consequence of the weakening of bee colonies that normally occur during the rainy season, which ease the invasion of them by phorid flies from the environment.

Abstract - The objective of this work was to determine the macronutrient dynamics in leaves and bunches of black pepper (Piper nigrum) throughout the plant reproductive cycles. The experiment was carried out in a commercial field of 'Bragantina' black pepper. Leaves and bunches were sampled every 21 days for one year, during two crop cycles. The bunches were sampled from the twenty eighth day after the appearance of inflorescences until the complete fruit maturation. Samples of leaves and bunches were dried, and the contents of N, P, K, Ca, Mg, and S were determined. N, K, and Ca were the most common macronutrients found in the bunches and leaves of black pepper. The accumulation of dry matter in the bunches was similar for both cycles and it was adjusted to the linear and quadratic models. The accumulation and content of macronutrients followed the dry matter behavior trend. Macronutrient contents in leaves oscillate during the year, and K and Mg vary more than N, P, Ca, and S. The macronutrient contents in black pepper leaves and bunches depends on the plant vegetative stage, and this variation should be considered in the planning of the fertilization management. Resumo - O objetivo deste trabalho foi determinar a dinâmica de macronutrientes em folhas e cachos de pimenta-do-reino (Piper nigrum), ao longo dos ciclos reprodutivos da planta. O experimento foi realizado em uma lavoura comercial de pimenta-do-reino 'Bragantina'. Folhas e cachos foram amostrados a cada 21 dias, por um ano, durante dois ciclos de cultivo. Os cachos foram amostrados desde o vigésimo oitavo dia após o lançamento das inflorescências até a maturação completa dos frutos. As amostras de folhas e cachos foram secas, e os conteúdos de N, P, K, Ca, Mg e S foram determinados. N, K e Ca foram os macronutrientes mais comuns nos cachos e nas folhas de pimenta-do-reino. O acúmulo de matéria seca nos cachos de pimenta-do-reino foi similar nos dois ciclos e foi ajustado aos modelos linear e quadrático. O acúmulo e o conteúdo de macronutrientes seguiram a tendência de comportamento da matéria seca. O conteúdo de macronutrientes nas folhas oscila durante o ano, e K e Mg variam mais do que N, P, Ca e S. O conteúdo de macronutrientes em folhas e cachos de pimenta-do-reino depende do estádio vegetativo da planta, e essa variação deve ser considerada no planejamento do manejo de adubação.
