Gregariousness as a defence strategy of moderately defended prey: experiments with Pyrrhocoris apterus and avian predators

Popis výsledku v původním jazyce

Aggregations in insects carry out diverse functions, and gregariousness may also act as an antipredatory strategy, especially when combined with warning signalling. Despite many studies focused on the antipredatory function of gregariousness, there are still aspects needing further investigation: What aspects of predator behaviour are affected by prey gregariousness? Which of the antipredatory effects of aggregations are linked with aposematic coloration, and which will also work for non-aposematic prey? Does gregariousness of an aposematic species affect its mimetic relationships? We have studied these topics in the firebug, Pyrrhocoris apterus (Heteroptera), an aposematic red-and-black true bug with moderate chemical defence. Firebugs alternate between solitary and gregarious lifestyles throughout the year. We used hand-reared great tits (Parus major) as naive predators, and subjected them to avoidance training with either solitarily or gregariously presented firebugs, followed by a
