7.2.5. Recommendations for providing carbohydrates to caged adult workers in the laboratory

The use of a self made sucrose solution is easy, reduces chances of contamination, and depending on type of sugar used, can sustain honey bees for several weeks. Therefore, a good option for providing workers maintained in the laboratory with carbohydrates is to feed 50% (weight/volume) sucrose-tap water solution ad libitum (Barker and Lehner, 1978) using a feeder that meets the minimum criteria described previously (section 7.2.2.). Refer to section 7.5 for providing water to caged honey bees.
