Abstract

Galls induced by the aphid Tamalia coweni (Cockerell) were sampled from greenleaf manzanita (Arctostaphylos patula E. Greene) in Shasta County, California. Thirty galls from each of four sites were collected over a 5-year period (1990–1994) at roughly weekly intervals (N = 5010). The contents of each gall were examined and recorded. Excluding T. coweni, 25 taxa were encountered representing eight arthropod orders: Acari, Thysanoptera, Hemiptera, Neuroptera, Coleoptera, Diptera, Lepidoptera, and Hymenoptera. All play a minor role in the gall community with the exception of two species of Diptera. The data suggest that Leucopis sp. and Heringia sp. are obligatory predators of T. coweni and coexist by partitioning the aphid resource with different exploitation strategies. Heringia sp. has a relatively low infestation rate (10.8%) but is a superior competitor. Leucopis sp. compensates for its inability to compete effectively with Heringia sp. by maintaining a higher infestation rate (41.4%).

Résumé

Des galles provoquées par la présence du puceron Tamalia coweni (Cockerell) ont été recueillies sur des plants de la busserole Arctostaphylos patula E. Greene dans le comté de Shasta, en Californie. Trente galles ont été récoltées environ toutes les semaines, à quatre sites, pendant 5 ans (1990–1994) (N = 5010). Le contenu de chaque galle a été examiné et noté. À part T. coweni, 25 taxons appartenant à huit ordres d’arthropodes, acariens, thysanoptères, hémiptères, neuroptères, coléoptères, diptères, lépidoptères et hyménoptères, ont été identifiés. Tous jouent un rôle négligeable au sein des communautés gallicoles, à l’exception de deux espèces de diptères. Les données indiquent que Leucopis sp. et Heringia sp. sont des prédateurs obligés de T. coweni et ces espèces se partagent la ressource des pucerons en l’exploitant par des stratégies différentes. Heringia sp. a un taux d’infestation relativement faible (10,8%) mais est un meilleur compétiteur. Leucopis sp. compense son efficacité moins grande dans la compétition avec Heringia sp. en maintenant des taux élevés d’infestation (41,4%).
