Abstract: Chestnut honey is an important revenue for beekeepers in Aquitaine. This study aims to understand the influence of different factors: weather, the condition of the colonies, flowering, and the state of the stands of chestnut. The optimum flowering is reached in early July, but these dates seem to vary gretly from one year to another. Two hives were followed with a continuous system register of the weight and weather conditions (temperature, humidity and rainfall). The locations of the two hives have an abundant forest cover, but often older and abandoned. The Gelos hive had a superior production. Within 1500 m, the two apiaries were located in a heavily forested area, dominant chestnut, 65% and 42% of forest land, for Gelos and Ordiarp respectively. Honey production is concentrated in about 8-10 days (late July). This pattern was maintained in two years and in two apiaries. During this period the colonies increased by about 15kg. The period of weight gain corresponds to the flowering chestnut. This is evidence that these two sites chestnut is the main source of nectar. From the peak of flowering, the colonies begin to lose or maintain weight, ie consumption is greater than the harvest. In a daily or hourly variation there was a positive correlation with temperature, but the high relative humidity had a negative influence on increases in weight. Rainfall had no significant influence on the added weight. Honey´s pollen analyses confirm that the chestnut is the main source of nectar in these two areas, but particularly in the Gelos hive. Concerning the Honey production origin designation in Ordiarp designation must be considered all floral flowers with chestnut honey as dominant ; in the Gelos‟s the chestnut pollen was the main source. Considering the value of 10 Euros per kg of honey, and an average production of 15 kg per hive, the beekeeper with 100 hives have an income, on average 15 000 Euros per year. We can conclude of the importance of this product in the local economy and rural development.
