Abstract

Stem fauna of the native sunflower species, Helianthus annuus L., H. petiolaris ssp. petiolaris Nuttall, H. maxmiliani Schrader, and H. rigidus ssp. subrhomboideus (Rydberg) Heiser, which occur in western North Dakota are reported. Species of insects recovered in order of relative abundance were: Cylindrocopturus adspersus(LeConte) (Coleoptera: Curculionidae), Mordellistena sp. (Coleoptera: Mordellidae), Suleima helianthana (Riley) (Lepidoptera: Tortricidae), Isophrictis similiella (Chambers) (Lepidoptera: Gelechiidae), and Dectes sayi Dillon and Dillon (Coleoptera: Cerambycidae). A single species of parasitoid, Nealiolus curculionis (Fitch) (Hymenoptera: Braconidae), was reared from C. adspersus larvae.
