  • Liste Commentée Des Pentatomoidea De La Manche
    Liste commentée des Pentatomoidea de la Manche Deuxième partie : les Pentatominae Cet article constitue donc le deuxième volet de l’inventaire provisoire des pentatomoïdes de la Manche. Le premier, rappelons-le, paru dans L’Argiope 73 (LIVORY , 2011) traitait les Acanthosomatidae, les Cydnidae, les Thyreocoridae, les Scutelleridae et deux sous-familles de Pentatomidae, les Podopinae et les Asopinae. Nous terminons ce recensement avec la sous-famille des Pentatominae. Avant de poursuivre notre énumération, je voudrais rendre hommage à Jean PÉRI C ART (1928-2011) qui nous a quittés l’année passée. Cet éminent entomologiste avait rédigé la plupart des ouvrages de la Faune de France consacrés aux punaises, soit comme auteur unique soit en tant que co-auteur. Les travaux de PÉRI C ART sur les hétéroptères ont une valeur immense et une portée internationale. Les volumes sur les pentatomoïdes étaient en cours de parution et sur les cinq prévus, seuls deux actuellement ont vu le jour. Nous espérons que la disparition de cet auteur n’empêchera pas la poursuite de cette publication et qu’elle conservera le même niveau scientifique. Sous-famille des Pentatominae Ces punaises possèdent un scutellum triangulaire qui ne dépasse guère en arrière le milieu de l’abdomen, ce qui les distingue nettement des Podopinae. Le rostre est mince et atteint au moins les hanches moyennes. Son premier article est logé dans un sillon qui occupe toute la longueur de la tête. Ce caractère sépare sans ambiguïté les Pentatominae des Asopinae. La 28 Bull. trim. ass. Manche-Nature, L’Argiope N° 76-77 (2012) plupart des Pentatominae sont phytophages mais quelques-uns complètent ce régime par une nourriture animale.

  • Punaises » De Savoie Etat Des Connaissances En 2019 Familles Des Pentatomidae, Scutelleridae, Cydnidae, Acanthosomatidae, Thyreocoridae, Plataspidae
    Novembre 2019 « Punaises » de Savoie Etat des connaissances en 2019 Familles des Pentatomidae, Scutelleridae, Cydnidae, Acanthosomatidae, Thyreocoridae, Plataspidae Les « PUNAISES » de Savoie Liste illustrée des espèces, état 2019 André MIQUET Conservatoire d’Espaces naturels de Savoie (CEN Savoie), décembre 2019 Méconnues et mal aimées … Il n’est pas exagéré de dire que les punaises ne bénéficient ni de bataillons de naturalistes dédiés, ni d’un capital sympathie démesuré auprès du grand public. L’imaginaire collectif ne trouve aucune vertu à ces insectes exclusivement associés à des nuisances, notamment olfactives ... Le sous-ordre des hétéroptères (punaises et gendarmes) sont des insectes souvent plus ou moins aplatis, aux ailes en partie durcie, souvent colorées. Prédateurs ou phytophages, leur appareil buccal piqueur-suceur leur permet d’aspirer la lymphe des chenilles comme la sève des plantes. Le CEN Savoie pend en charge leur connaissance dans ce département dans le cadre de sa stratégie envers les « groupes orphelins ». Les Hétéroptères comportant 1400 espèces en France, il est proposé de focaliser sur le groupe des Pentatomoides, et ce pour trois raisons : - « seulement » 120 espèces en France, - la plupart identifiables sur (bonnes) photos macros, - guide national et atlas régional (Franche-Comté) récemment parus. Ce groupe est donc à même de bénéficier d’une meilleure prise en compte, en attendant un atlas de répartition, une liste d’espèces déterminantes ZNIEFF, une liste rouge, et une stratégie de conservation. Au- delà de leurs deux espèces exogènes, bien loin de n’être qu’une « nuisance », les punaises sont avant tout une partie intégrante de notre patrimoine naturel ! … désormais prêtes à « sortir de l’ombre » en Savoie Afin de promouvoir et faciliter leur identification en vue d’un pré-atlas de répartition, 79 espèces connues ou à rechercher en Savoie sont présentées.

INFORMATION TO USERS This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image.

The contents of each chapter generally reflect the special interests of the contributors. Some have presented a detailed taxonomic review of the families concerned; some have referred the readers to standard taxonomic works, in view of the breadth and complexity of the subject concerned, and have concentrated on ecological or physiological aspects; others have chosen to review insects of a specific set of habitats.

McDonald Department of Entomology Quaestiones Entomologicae University of Alberta 2:7-150. 1966 The male genitalia of 85 and the female genitalia of 80 species of North American pentatomoid bugs are described. The male genitalia were found to vary very widely in the tribes Pachycorini and Odontoscelini of the Scutellerinae. The female genitalia were less variable. Species in the tribe Scutellerini are very easily defined on the basis of the male genitalia. The Pentatominae, Asopinae, and Podopinae are very uniform in the structure of the genitalia and are closely related to one another. The spermatheca of all species examined in the above sub­ families except Trichopepla semivittata (Say) (Pentatominae), has an elongate membraneous dilation with a central sclerotized rod. Median penal lobes occur only in the Pentatominae, Asopinae and Podopinae with the exception of one scutellerine, Symphylus carribeanus(Kirkaldy). The Cydnidae exhibit great diversity of form both in the male and female genitalia. The status of this family will remain obscure until further species have been examined. The Acantho- somidae posses pentatomine type genitalia. The genitalia of Piezostemum subulatum (Thunberg) do not resemble those of other species of the Tessaratomidae so far described. On the basis of this work it is suggested that the Scutellerinae be accorded family status; the Asopinae and Podopinae should be reduced to tribes within the Pentatominae; the Acanthosomidae reduced to subfamily status ivithin the Pentatomidae and Piezostemum should be raised to subfamily status within the Tessaratomidae.

    PEST MANAGEMENT OF JAPANESE BEETLE (COLEOPTERA: SCARABAEIDAE) AND A STUDY OF STINK BUG (HEMIPTERA: PENTATOMIDAE) INJURY ON PRIMOCANE-BEARING CANEBERRIES IN SOUTHWEST VIRGINIA Laura Michele Maxey Thesis submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN LIFE SCIENCES in Entomology Douglas G. Pfeiffer, Chair Thomas P. Kuhar Jeremy A. Pattison February 17, 2011 Blacksburg, VA Keywords: Caneberry, raspberry, blackberry, Rubus , Japanese beetle, Popillia japonica , stink bug, Pentatomidae, insecticides, cultivar susceptibility, and geranium toxicity © Laura Michele Maxey PEST MANAGEMENT OF JAPANESE BEETLE (COLEOPTERA: SCARABAEIDAE) AND A STUDY OF STINK BUG (HEMIPTERA: PENTATOMIDAE) INJURY ON PRIMOCANE- BEARING CANEBERRIES IN SOUTHWEST VIRGINIA Laura Michele Maxey ABSTRACT Field experiments (2007-2009) and laboratory bioassays (2009) tested the efficacy of insecticides with short pre-harvest intervals, caneberry cultivar susceptibility, and geranium toxicity for reducing Japanese beetle (JB) activity on primocane-bearing caneberries. Deltamethrin, chlorantraniliprole, bifenthrin, lime-alum, and thyme oil reduced JB activity in the field. Deltamethrin, chlorantraniliprole, acetamiprid, an azadirachtin and pyrethrin mixture, an azadirachtin and neem oil extract mixture, and an extract of Chenopodium ambrosioides reduced JB activity during the bioassays. ‘Prelude’ had significantly more JB than ‘Anne’, ‘Caroline’, ‘Heritage’, ‘Dinkum’, or ‘Himbo Top’ and ‘Prime-Jan’ had significantly more JB than ‘Prime-Jim’. Compared to certain cultivars, ‘Heritage’, ‘Caroline’, ‘Himbo Top’, and ‘Prime-Jan’ had higher percentages of injured fruit and ‘Autumn Bliss’, ‘Heritage’, and ‘Caroline’ produced greater marketable and overall yields. ‘Prime-Jan’ produced more overall yield than ‘Prime-Jim’; marketable yields from both blackberry cultivars were similar.

Abstract. The list of 44 species of true bugs of the family Pentatomidae of the Central Ciscaucasia is given. 10 Аннотированный список species are recorded for this territory for the first time. Pentatomidae Центрального Предкавказья Несмотря на хорошую изученность полужесткокрылых Кавказа, Центральное Предкавказье Подсемейство Podopinae остается «белым пятном» в исследовании этой группы насекомых. В частности, до настоящего момента не был Vilpianus galii (Wolff, 1802) уточнен видовой состав клопов-щитников – крупного семейства полужесткокрылых, насчитывающего 100 Материал.

  • On the Fore Legs of Seed Bugs (Heteroptera: Lygaeidae): Aggression and Allometric Scaling in Scolopostethus Affinis Schilling
    21 December 2000 JOURNAL OF THE KANSAS ENTOMOLOGICAL SOCIETY 73( I), 2000, pp. 6-10 On the Fore Legs of Seed Bugs (Heteroptera: Lygaeidae): Aggression and Allometric Scaling in Scolopostethus affinis Schilling RAFAELLUCAS RODRIGUEZ S. Department of Entomology, Haworth Hall, University of Kansas, Lawrence, Kansas 66045, USA ABSTRACT: Males and females of the seed bug Scolopostethus affinis used their fore legs with modified femora in intra-sexual aggression. Males were smaller than females, but had larger fore femora. Allometric scaling of the fore femora on body size was similar in both sexes. This argues against hypotheses that the often spiny and enlarged fore legs of seed bugs serve to move seeds or to aid in movement in confined spaces. Instead, they may function primarily in aggression. The fore legs of many seed bugs (Lygaeidae), especially among the Rhy- parochrominae, are strikingly modified with enlarged and spiny femora (Schuh and Slater, 1995) so that they seem raptorial (Borror et al., 1992). This is puzzling for bugs which are primarily herbivorous (Sweet, 1979; Schuh and Slater, 1995), and two main hypotheses have been proposed as explanations: that the fore legs are used to manipulate seeds along irregular substrates (Sweet, 1964a), or that they aid in movement within enclosed spaces (Schuh and Slater, 1995). However, another pos- sibility is that the modified legs of these bugs are used in aggressive contests, as for example in coreid bugs with their hind legs (Mitchell, 1980; Miyatake, 1993, 1997; Eberhard, 1998). There are some descriptions of fights involving the fore legs in seed bugs. Males of Neacoryphus bicrucis grapple to defend patches of their host plant (McLain, 1984).
