Abstract

We have recorded the sounds produced by a strong colony of the stingless bee Trigona biroi. Data gathered were in the form of sound pressure versus time graphs. Fast Fourier Transforms of these data show frequency peaks of sound emitted by queenright and queenless colony. The frequency peaks of queenright colony are 324 ± 11 Hz and 147 ± 9 Hz and were attributed to fanning. The frequency peaks of queenless colony are 322 ± 6 Hz, 167 ± 3 Hz, 223 ± 3 Hz and 438 ± 3 Hz, two of which correspond to fanning (same as the queenright) and the two others are attributed to the "stress" felt by the bees in being queenless.
