water at er treatment with 30 percent sucrose solution. High-strain bees
were signii cantly more responsive to water following sensitization and
maintained a higher responsiveness to water throughout the process of
habituation (Figure 5.11).
Finally, Kolavennu tested the ef ects of single and repeated stimula-
tion with a 50 percent sucrose solution. Newly emerged high- and low-
strain workers were exposed to 1, 3, and 6 stimulations with a 50 per-
cent sucrose solution, respectively. Four minutes at er stimulation, they
were tested with 10 stimulus treatments of water touched to the antenna.
h e total number of responses demonstrated the degree of sensitization
and resistance to habituation. h e number of sucrose stimulations

Habituation curves of high- and low-strain bees tested for response
sensitivity using an increasing series of concentrations. h e last sucrose
concentration used to test for sensitivity was 30 percent. At erward, bees were
presented with 10 trials of water. h e i gure shows the proportion of highs and
lows responding to 0 to 10 water trials of 92 bees.
