The stingless bee keeping has been improved considerably in the last years and, consequently, the demand for colonies has increased. However, the breeding techniques still need to be improved to reach the necessary production scale. The feeding system is one of the issues that must be studied and improved, because long periods of low availability of food resources constraint the production of new colonies. The present study aimed to test an artificial diet to replace the pollen for Melipona flavolineata. It was investigated the nutritional composition of their natural food (stored pollen) and of the artificial diet (based on soybean extract). The effect of the artificial diet was tested at the survival and size of brood and longevity of adult workers. The artificial diet presented a different nutritional composition compared to the stored pollen. It was richer in carbohydrates and lipids, but poorer in proteins. However, this difference did not affect the survival and size of brood and longevity of adult workers, but not drastically. It is recommended to reduce the amount of sugar and to add new ingredients with higher protein content in future diets. The diet based on soybean extract showed to be a good substitute for pollen, but not perfect. Small changes can be adressed based on the results of the present contribution to reach an artificial diet with better quality.

Stingless beekeeping is an old practice in the Americas. However, the activity is still undeveloped, requiring management techniques improvements. This study evaluated nutritional alternatives for the Amazonian stingless bee Melipona flavolineata, looking for a food replacement for honey and fermented pollen. The following food replacement were compared to honey (T1): inverted sugar syrup with minerals (T2), inverted sugar syrup with amino acids and vitamins in the following concentrations: 0.5% (T3), 1.0% (T4) and 10% (T5). It was compared to fermented pollen (T1), fermented foods with inoculum of fermented pollen of M. flavolineata consisting of: commercial pollen of A. mellifera (T2); brewers yeast (T3), and soybean extract in two different concentrations of proteins (T4, 12%; and T5, 18%). The nutritional value of the diet was based on the daily intake, on the weight of workers, on the size of hypopharyngeal glands acini and on the size of oocytes. The cost of the ingredients of the diets was also evaluated. The results showed that among the alternatives to honey, there were no significant differences between the control and all treatments. Differences were found only between the sizes of acini of workers that were fed by treatments 2 and 4, in which treatment 4 was superior. The costs of ingredients indicated the treatment 2 as cheaper than the others. Among the alternatives to the fermented pollen, larger differences were found. Consumption of treatment 4 was significantly higher than treatment 3, indicating a greater acceptance of soybean extract in relation to yeast. For other parameters evaluated, treatment 5 was superior to all others and its cost was much lower than the T2 and similar to T3 and T4. We concluded that the best alternative for the nutrition of M. flavolineata are the sugar inverted syrup with minerals, and semi-artificial fermented pollen based in soybean extract (T5, 18% proteins). Newly formed colonies, having 500-600 bees, must receive 10 to 20 ml of syrup and 25 g of semi-artificial fermented pollen weekly.
