Social Buffering In A Eusocial Invertebrate: Termite Soldiers Reduce The Lethal Impact Of Competitor Cues On Workers, Li Tian, Evan L. Preisser, Kenneth F. Haynes, Xuguo Zhou

Entomology Faculty Publications

While the impact of predator‐induced stress on prey has received considerable attention, there has been far less research into the effect of competitors. Cues from aggressive competitors should be particularly likely to evoke behavioral and/or physiological responses, since they may be indicative of both direct (interference) and indirect (exploitative) threats. The danger posed by such competitors, and the “fear” they evoke, should be reduced at lower competitor densities and by the presence of individual conspecifics specialized for defense. We assessed how Reticulitermes flavipes termite workers and soldiers were affected by cues from conspecific nestmates, conspecific non‐nestmates, and the heterospecific competitor …
