Abstract

The 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.

Résumé

Les larves de Rhinocyllus conicus Froel. se nourissent à l'intérieur des capitules de Carduus nutans en formant des tunnels à travers du cal qui se trouve près des sites d'alimentation ou en formant des chambres de cal sous les fleurs en développement ou en creusant la moelle du pédoncule. L'induction du cal par R. conicus est une réponse quasi-cécidologique qui donne à la larve des nutriments additionels et un gîte. La formation du cal réduit aussi les ressources qui étaient destinées au développement des capitules futurs de la plante.
