����������� The community of insects inhabiting stalks of wild and cultivated sunlfower, Helianthus annus, was examined by dissecting overwintered stalks.� The sunflower stem weevil, Cylindrocopturus adspersus, (Coleoptera: Curculionidae) was the dominant herbivore in vascular tissues of both wild and cultivated stalks, although infestation averaged 30-40% lower in wild plants, and the rate of parasitism seven fold higher.�� The tumbling flower beetle, Mordella sp. (Mordellidae) infested 52% of both plant types, but larval densities were 4.5 times greater in wild stalks.� The longhorned beetle Ataxia hubbardi (Cerambycidae) infested the central pith core of 43% of wild stalks and 55% of cultivated stalks.� Another cerambycid, Dectes texanus, infested 45% of cultivated plants, but was not found in wild plants.� Predaceous larvae of a small tiger beetle (Cicindellidae) were found in 2.4% of wild stalks.� Among Lepidoptera, the sunflower root moth, Pelochrista womanana (Tortricidae), occurred in the roots of 20% of cultivated plants and 6.1% of wild.� The sunflower budmoth, Suleima helianthana (Tortricidae) was recovered from 26.5% of wild stalks, but only 2% of cultivated.� Two gelechiids, Isophrictis similiella and Isophrictis sp. occurred exclusively in wild stalks, infesting 2.4% and 24.6% of plants, respectively.� Two species of Diptera (Ottitidae and Drosophilidae) were found as maggot clusters in 8% of cultivated stalks and assumed to be saprovores.� One cluster of maggots was parasitized by a Eulophid wasp.� The potential significance of divergent insect community structure between wild and cultivated sunflower is discussed in the context of resource concentration associated with plant domestication.�
