The actual (not average) ratios (%) of dropping individuals of the different beetle species and developmental stages in response to the Tactile Stimulation, Vibration and CO2 treatments.

Due to the very low dropping rates in the tactile and vibration treatments, only in the CO2 treatment each group was statistically compared to the respective group in the control treatment (McNemar's test, α = 0.01). No result was statistically significant.
