Bee speciesApis mellifera and Apis cerana are the only honey-producing bees known in Nepal. A. cerana lives in Nepal at an altitude of 60 to 3500 m (Thapa, 2001) and produces honey two times a year. The first time is during the summer (March to May) and the second time during the winter (November to December). A. cerana is much more resistant than Apis mellifera to cold and predators. During the winter, most Apis cerana colonies are reduced because of the harsh weather and the low amount of flowers. Nevertheless, compared to A. mellifera, A. cerana can survive in low temperatures (i.e. -0,1 °C) (Thapa, 2001) because their beehives (i.e. log hive) can protect themselves from the cold. Furthermore, A. cerana is resistant to the parasite, Varroa destructor. The acarid breed feeds on bees’ larva. A. melifera is very sensitive to this parasite and causes an incapacity to fly, an abdomienal malformation and appearance of cannibalism (Experimental and Applied Acarology, 2000). A. cerana is very famous in Nepal because of the low cost of its beehive, the log hive. Farmers can build their own beehives. The principle is to dig a hole in a trunk (the size is about 50 cm in diameter and 65 cm in height), and then a cap is necessary to protect the top of the beehive from cold and predators (e.g. Marte flavigula). Honey developmentIn the Teraï, a region located at an altitude of 60 to 300 m (FAO), there are counts of about 120 000 colonies of A. cerana (Thapa, 2001). The flora is also favourable to honey-production thanks to tropical plants. The weather is moderate all year long. The log hives permit honey production from A. cerena. References
