摘要: Individual Leptogenys kitteli (Hymenoptera: Formicidae) workers produce stridulatory
pulses at faster rates after exposure to prey larvae placed nearby the nest and after air-puff disturbances
at the nest entrance than during unstimulated social interactions within the nest. Workers produce
chirps (trains of stridulatory pulses) at faster rates after exposure to prey larvae than during unstimulated
social interactions, including groups of chirps (bursts) where the intervals between chirps
decrease below 60 ms. Such bursts do not occur in unstimulated social interactions. Chirp bursts with
intervals 10 ms (disturbance bursts) occur immediately after air puffs at the nest entrance. Disturbance
bursts are not observed after exposure to prey larvae or during unstimulated social interactions.
The rates of disturbance bursts decline rapidly within 10 s after an air puff, whereas episodes
of chirp bursts extend over periods of 30 s or longer when groups of ants are moving prey larvae into
the nest. The differences in the rates of stridulatory pulses and chirps and in the durations of
stridulatory activity observed in the context of different types, intensities, and durations of stimulation
contribute to evidence that stridulation has a signi�cant communicatory role in colony activities of
many ant species, even in genera, such as Leptogenys, in which a stridulatory organ has not been
retained in every species. A better understanding of how ants produce and interpret vibrations may
lead to new methods that to improve attractiveness of baits, or repel ants from electrical equipment
housings where opportunistic colonies frequently nest.
