Research Focus

Develop a rearing technique

Six different designs of nest boxes were produced:

icipe-cb1     icipe-cb4
icipe-cb2     icipe-cb5
icipe-cb3    icipe-cb6

Each design differs in size of burrow and type of tunnels. However, more assays in the field for setting nest boxes in different habitats are required to measure the effect of the habitat type on the success rate to colonise the nest boxes. Reliability of this experiment in different habitats will give full general spectra of the nest boxes success to broad range of carpenter bee species.

Species characterisation using morphometrics and molecular tools
Samples have partially been collected in Kenya and in Ethiopia. Because of differences in some carpenter bees species in the two countries, more fieldwork is required in all the 5 project countries.

Future research:
•    Stimulation of stingless bee foragers with a specific floral odour inside and outside the hive, to enhance targeted pollination, especially in greenhouses.
•    Artificial queen production in stingless bees using in vivo and in vitro techniques.
•    Pollination efficiency of stingless bees, honey bee, hand pollination on strawberry, water melon, onion.
•    Carpenter bee developmental cycle and rearing.
•    Species characterisation of stingless bees and carpenter bees.
•    Pollen and nectar resources of stingless bees.
