I do not know of this information, but would suggest looking at the bee bibliography: http://alembic.nal.usda.gov:8088/ Some examples I found are: AUTHOR: Yes'kov, Y. K. (Res. Inst. Apic., Rybnoye (Ryazan Region), U.S.S.R.) ARTICLE TITLE: Sound Apparatus Of The Bee Apis mellifera L. JOURNAL TITLE: Biophysics 14(1):166-176, Figs. Refs YEAR OF PUBLICATION: 1969 NOTES: Translation From Russian In: Biofizika 14(1):158-166, 1969. 'In The Work We Investigated The Mechanism Of Emission Of Sounds By Bees Based On The Vibration Of The Thorax Effected By The Indirect Action Of Wing Muscles. These Sounds Are Amplified Through The Vibration Of The Wings. The Presence In The Sound Of Bees Of Maximum Intensity At Frequencies Of 400-500 C/S Is To Be Explained By The Fact That The Longitudinal Muscles Vibrate The Thorax At This Frequency. The Pulsating Sounds Emitted By Dancing Bees Are Produced Chiefly Under The Action Of The Same Muscles. The Wing Plates Perform Two Functions In The Production Of Sounds: A) Emit The Sounds As Any Vibrating Plate; The Fundamental Frequency Of These Sounds Is Determined By The Frequency Of The Sweeps By The Wings; And B) Are Diffusers Amplifying The Vibration Of The Thorax.'
