PIS CERANA in low-cost hive making, tested in Bangladesh. The

clay block hives are easy to make

once the set of moulds are made. The hives are durable, especially when reinforced with 2 kg of Portland cement. The trials suggested that the hives were acceptable to the bees. The hives are heavy and unsuitable for migratory

beekeeping. However families with few hives usually do not practise this type of beekeeping.
