AbstractThe larvae of Rhinocyllus conicus Froel. feed within the flowerheads of Carduus nutans by tunneling through callus that appears near feeding sites, by forming chambers of callus beneath developing florets, or by tunneling within pith of the peduncle. The induction of callus by R. conicus is a gall-like response providing the larvae with additional nutriment and a shelter. Callus formation also reduces plant resources destined for developing additional flowerheads.
