Supplementary material S24: Time course of the loudest Varroa jolting pulse compared to that of a honeybee colony and single bee individual.

<p>Time course of the loudest <em>Varroa </em>jolt on brood-comb with the signal from the full colony and a single bee. The signal seen here in each panel is the integral of the magnitude of acceleration with respect to time. The background vibration that is inherent to the room was calculated and subtracted from this data. The loudest jolt (red) is here compared to the signal of a single bee (black) and the vibrations of the full colony at low and high signal (black). High signal is captured when the frame containing the accelerometer is empty of brood. Low signal is captured when the frame is fully loaded with brood and/or honey. The whooping signal (panel a) was captured during a period of high signal.</p>
