Charlet, USDA, ARS Research Entomologist he sunflower stem weevil, Cylindrocopturus adspersus T(LeConte), is an insect pest that has caused economic damage to sunflower in the northern and southern Great Plains of the USA and into Canada. It belongs in the order Coleoptera (beetles) and family Curculionidae (weevils), and has also been called the spotted sunflower stem weevil. It is native to North America and has adapted to wild and cultivated Figure 1.

The sunflower moth is most commonly controlled w"ith pesticides. Resistânt plants would provide an environmentally friendly approach to con- trolling this pest. Evaluation of 680 cultivated sunflower accessions in the U.S. National Plant Germplasm System's sunflower (Flelianthus spp.) collection at the North Central Regional Plant Introduction Stauon, Ames, IA, USA. revealed 51 accessions resistant to sunflower moth feeding. A 1-3-5-7-9 rating scale is presented to compare accessions damaged by the pest. The proceeding evalua- tion data were entered into the Germplasm Resources Information Network (GRIN) and made available to researchers worldwide. Key words: Sunflower, Helio,nthus, Homoeosoma electellum, plarfi germplasm, host plant resistance to insects, sunflower moth. INTRODUCTION The United States National Plant Germplasm System's collection of sunflower, Helianthus spp., contains 3,670 accessions of which 1,495 are cultivated (H. clnnllus L.). From l9B5 to 1992, 680 cultivated accessions were evaluated for sun- flower moth, Homoeosoma electellum (Hulst)(Lepidoptera: Pgraltdae), resistance. The procedure used for these evaluations involved placing eggs on sunflower heads and covering with a Delnet@ bag until harvest. -

São Paulo 2017 ! ______________________ ______________________ ______________________ ______________________ ______________________ ! RESUMO Em 1988, John Cage inventou Anarchy , livro em que, a partir de escritos experimentais, valorizou as vidas de mulheres e homens anarquistas que marcaram seu percurso ético-estético libertário desde meados dos anos 1940 até a década de 1990, quando em seus últimos trabalhos, “number pieces” (1987-1992), apresentou o que denominou “harmonia anárquica”. Foi a partir da coexistência com artistas e militantes na Black Mountain College, no final da década de 1940, assim como em Nova York com o The Living Theatre (TLT) , que o artista já conhecido por seu corajoso “piano preparado” passou a elaborar o anarquismo como prática de vida. “4’33” (1952), ação direta contra a representação musical dos sons e em favor da incorporação dos ruídos excluídos pelas salas de concerto, irrompeu empolgada por essa aproximação libertária. Nas décadas seguintes, vivendo ao lado de artistas e anarquistas, afastado da cidade, em Stonypoint, iniciou a publicação de how to improve the world (you only make matters worse) (1965-1982), diário mantido por mais de quinze anos e no qual apresentou a lida com os escritos de Henry David Thoreau, preocupações antimilitares e ecológicas. -

Working List of Prairie Restricted (Specialist) Insects in Wisconsin (11/26/2015)
Working List of Prairie Restricted (Specialist) Insects in Wisconsin (11/26/2015) By Richard Henderson Research Ecologist, WI DNR Bureau of Science Services Summary This is a preliminary list of insects that are either well known, or likely, to be closely associated with Wisconsin’s original native prairie. These species are mostly dependent upon remnants of original prairie, or plantings/restorations of prairie where their hosts have been re-established (see discussion below), and thus are rarely found outside of these settings. The list also includes some species tied to native ecosystems that grade into prairie, such as savannas, sand barrens, fens, sedge meadow, and shallow marsh. The list is annotated with known host(s) of each insect, and the likelihood of its presence in the state (see key at end of list for specifics). This working list is a byproduct of a prairie invertebrate study I coordinated from1995-2005 that covered 6 Midwestern states and included 14 cooperators. The project surveyed insects on prairie remnants and investigated the effects of fire on those insects. It was funded in part by a series of grants from the US Fish and Wildlife Service. So far, the list has 475 species. However, this is a partial list at best, representing approximately only ¼ of the prairie-specialist insects likely present in the region (see discussion below). Significant input to this list is needed, as there are major taxa groups missing or greatly under represented. Such absence is not necessarily due to few or no prairie-specialists in those groups, but due more to lack of knowledge about life histories (at least published knowledge), unsettled taxonomy, and lack of taxonomic specialists currently working in those groups. -
Macrolepidoptera Inventory of the Chilcotin District
Macrolepidoptera Inventory of the Chilcotin District Aud I. Fischer – Biologist Jon H. Shepard - Research Scientist and Crispin S. Guppy – Research Scientist January 31, 2000 2 Abstract This study was undertaken to learn more of the distribution, status and habitat requirements of B.C. macrolepidoptera (butterflies and the larger moths), the group of insects given the highest priority by the BC Environment Conservation Center. The study was conducted in the Chilcotin District near Williams Lake and Riske Creek in central B.C. The study area contains a wide variety of habitats, including rare habitat types that elsewhere occur only in the Lillooet-Lytton area of the Fraser Canyon and, in some cases, the Southern Interior. Specimens were collected with light traps and by aerial net. A total of 538 species of macrolepidoptera were identified during the two years of the project, which is 96% of the estimated total number of species in the study area. There were 29,689 specimens collected, and 9,988 records of the number of specimens of each species captured on each date at each sample site. A list of the species recorded from the Chilcotin is provided, with a summary of provincial and global distributions. The habitats, at site series level as TEM mapped, are provided for each sample. A subset of the data was provided to the Ministry of Forests (Research Section, Williams Lake) for use in a Flamulated Owl study. A voucher collection of 2,526 moth and butterfly specimens was deposited in the Royal BC Museum. There were 25 species that are rare in BC, with most known only from the Riske Creek area. -
197 Section 9 Sunflower (Helianthus
SECTION 9 SUNFLOWER (HELIANTHUS ANNUUS L.) 1. Taxonomy of the Genus Helianthus, Natural Habitat and Origins of the Cultivated Sunflower A. Taxonomy of the genus Helianthus The sunflower belongs to the genus Helianthus in the Composite family (Asterales order), which includes species with very diverse morphologies (herbs, shrubs, lianas, etc.). The genus Helianthus belongs to the Heliantheae tribe. This includes approximately 50 species originating in North and Central America. The basis for the botanical classification of the genus Helianthus was proposed by Heiser et al. (1969) and refined subsequently using new phenological, cladistic and biosystematic methods, (Robinson, 1979; Anashchenko, 1974, 1979; Schilling and Heiser, 1981) or molecular markers (Sossey-Alaoui et al., 1998). This approach splits Helianthus into four sections: Helianthus, Agrestes, Ciliares and Atrorubens. This classification is set out in Table 1.18. Section Helianthus This section comprises 12 species, including H. annuus, the cultivated sunflower. These species, which are diploid (2n = 34), are interfertile and annual in almost all cases. For the majority, the natural distribution is central and western North America. They are generally well adapted to dry or even arid areas and sandy soils. The widespread H. annuus L. species includes (Heiser et al., 1969) plants cultivated for seed or fodder referred to as H. annuus var. macrocarpus (D.C), or cultivated for ornament (H. annuus subsp. annuus), and uncultivated wild and weedy plants (H. annuus subsp. lenticularis, H. annuus subsp. Texanus, etc.). Leaves of these species are usually alternate, ovoid and with a long petiole. Flower heads, or capitula, consist of tubular and ligulate florets, which may be deep purple, red or yellow. -

Zoogeography of the Holarctic Species of the Noctuidae (Lepidoptera): Importance of the Bering Ian Refuge
© Entomologica Fennica. 8.XI.l991 Zoogeography of the Holarctic species of the Noctuidae (Lepidoptera): importance of the Bering ian refuge Kauri Mikkola, J, D. Lafontaine & V. S. Kononenko Mikkola, K., Lafontaine, J.D. & Kononenko, V. S. 1991 : Zoogeography of the Holarctic species of the Noctuidae (Lepidoptera): importance of the Beringian refuge. - En to mol. Fennica 2: 157- 173. As a result of published and unpublished revisionary work, literature compi lation and expeditions to the Beringian area, 98 species of the Noctuidae are listed as Holarctic and grouped according to their taxonomic and distributional history. Of the 44 species considered to be "naturall y" Holarctic before this study, 27 (61 %) are confirmed as Holarctic; 16 species are added on account of range extensions and 29 because of changes in their taxonomic status; 17 taxa are deleted from the Holarctic list. This brings the total of the group to 72 species. Thirteen species are considered to be introduced by man from Europe, a further eight to have been transported by man in the subtropical areas, and five migrant species, three of them of Neotropical origin, may have been assisted by man. The m~jority of the "naturally" Holarctic species are associated with tundra habitats. The species of dry tundra are frequently endemic to Beringia. In the taiga zone, most Holarctic connections consist of Palaearctic/ Nearctic species pairs. The proportion ofHolarctic species decreases from 100 % in the High Arctic to between 40 and 75 % in Beringia and the northern taiga zone, and from between 10 and 20 % in Newfoundland and Finland to between 2 and 4 % in southern Ontario, Central Europe, Spain and Primorye. -
A Systematic Study of the Family Rhynchitidae of Japan(Coleoptera
Humans and Nature. No. 2, 1 ―93, March 1993 A Systematic Study of the Family Rhynchitidae of Japan (Coleoptera, Curculionoidea) * Yoshihisa Sawada Division of Phylogenetics, Museum of Nature and Human Activities, Hyogo, Yayoi~ga~oka 6, Sanda, 669~ 13 fapan Abstract Japanese RHYNCHITIDAE are systematically reviewed and revised. Four tribes, 17 genera and 62 species are recognized. Original and additional descriptions are given, with illustrations of and keys to their taxa. The generic and subgeneric names of Voss' system are reviewed from the viewpoint of nomenclature. At the species level, 12 new species Auletobius planifrons, Notocyrtus caeligenus, Involvulus flavus, I. subtilis, I. comix, I. aes, I. lupulus, Deporaus tigris, D. insularis, D. eumegacephalus, D. septemtrionalis and D. rhynchitoides are described and 1 species Engnamptus sauteri are newly recorded from Japan. Six species and subspecies names Auletes carvus, A. testaceus and A. irkutensis japonicus, Auletobius okinatuaensis, Aderorhinus pedicellaris nigricollis and Rhynchites cupreus purpuleoviolaceus are synonymized under Auletobius puberulus, A. jumigatus, A. uniformis, Ad. crioceroides and I. cylindricollis, respectively. One new name Deporaus vossi is given as the replacement name of the primally junior homonym D. pallidiventris Voss, 1957 (nec Voss, 1924). Generic and subgeneric classification is revised in the following points. The genus Notocyrtus is revived as an independent genus including subgenera Notocyrtus s. str., Exochorrhynchites and Heterorhynchites. Clinorhynckites and Habrorhynchites are newly treated as each independent genera. Caenorhinus is newly treated as a valid subgenus of the genus Deporaus. The genera Neocoenorrhinus and Piazorhynckites are newly synonymized under Notocyrtus and Agilaus, respectively, in generic and subgeneric rank. A subgeneric name, Aphlorhynehites subgen.
