  • Taxonomy, Phylogeny and Resource Use of Glyptapanteles (Hymenoptera: Braconidae, Microgastrinae), Genus Highly Diversified in the Neotropics
    TAXONOMY, PHYLOGENY AND RESOURCE USE OF GLYPTAPANTELES (HYMENOPTERA: BRACONIDAE, MICROGASTRINAE), GENUS HIGHLY DIVERSIFIED IN THE NEOTROPICS BY DIANA CAROLINA ARIAS PENNA DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Entomology in the Graduate College of the University of Illinois at Urbana-Champaign, 2014 Urbana, Illinois Doctoral Committee: Professor James B. Whitfield, Chair, Director of Research Professor May R. Berenbaum Professor Sydney A. Cameron Dr. Marianne Alleyne Dr. Kevin P. Johnson ABSTRACT Among hymenopteran parasitoid wasps, Ichneumonoidea is one of the superfamilies with the highest number of species and includes the highly diverse Microgastrinae subfamily. Microgastrinae wasps are very abundant and can be collected in many different terrestrial habitats. A considerable number of species have been used in successful biological pest control programs, making it one of the most important insect groups. Glyptapanteles is one of the larger genera within Microgastrinae, which was segregated after several attempts to subdivide the gigantic genus Apanteles Foerster 1862. To date, 122 species have been described worldwide, of which only six are Neotropical, despite unpublished evidence that this genus is one of the largest in the Neotropics. Glyptapanteles are diminutive parasitoid wasps, which are free-living as adults, but as immatures, they attack exclusively larvae of Lepidoptera as a food resource for their developing larvae. These parasitoid wasps play a preponderant role in regulating their lepidopteran host populations and in maintaining high biological diversity in terrestrial ecosystems. A reliable revision for the Neotropics has not yet been attempted and many Glyptapanteles species remain undescribed. The scarcity of both taxon sampling and biological information is no longer standard for some Neotropical groups of insects.

  • When Species Matches Are Unavailable Are DNA Barcodes
    Wilson et al. BMC Ecology 2011, 11:18 http://www.biomedcentral.com/1472-6785/11/18 RESEARCH ARTICLE Open Access When species matches are unavailable are DNA barcodes correctly assigned to higher taxa? An assessment using sphingid moths John James Wilson1*, Rodolphe Rougerie1,5, Justin Schonfeld1, Daniel H Janzen2, Winnie Hallwachs2, Mehrdad Hajibabaei1, Ian J Kitching3, Jean Haxaire4 and Paul DN Hebert1 Abstract Background: When a specimen belongs to a species not yet represented in DNA barcode reference libraries there is disagreement over the effectiveness of using sequence comparisons to assign the query accurately to a higher taxon. Library completeness and the assignment criteria used have been proposed as critical factors affecting the accuracy of such assignments but have not been thoroughly investigated. We explored the accuracy of assignments to genus, tribe and subfamily in the Sphingidae, using the almost complete global DNA barcode reference library (1095 species) available for this family. Costa Rican sphingids (118 species), a well-documented, diverse subset of the family, with each of the tribes and subfamilies represented were used as queries. We simulated libraries with different levels of completeness (10-100% of the available species), and recorded assignments (positive or ambiguous) and their accuracy (true or false) under six criteria. Results: A liberal tree-based criterion assigned 83% of queries accurately to genus, 74% to tribe and 90% to subfamily, compared to a strict tree-based criterion, which assigned 75% of queries accurately to genus, 66% to tribe and 84% to subfamily, with a library containing 100% of available species (but excluding the species of the query).

  • MOTH SPECIES RICHNESS and SIMILARITY AMONG HABITATS in a Eucalyptus - DOMINATED LANDSCAPE
    Floresta e Ambiente MOTH SPECIES RICHNESS AND SIMILARITY AMONG HABITATS IN A Eucalyptus - DOMINATED LANDSCAPE Marcos Antonio Lima Bragança1 Paulo De Marco Jr.2 José Cola Zanuncio3 ABSTRACT Effects of fragments of native forest between Eucalyptus spp. stands on the Lepidoptera community was studied. A total of 790 morphospecies was collected at five sites along a transect: a residual forest and its edge, and into Eucalyptus spp. plantation (at 200, 400 and 600 m from the edge). The residual forest and its edge showed similar numbers of moth species, but these were significantly larger than those of the sites in the Eucalyptus plantation. Cluster analysis indicated that the sites with eucalyptus have a more similarly structured moth community when compared to these of residual forest and its border. Key words: Lepidoptera, Atlantic Forest, species richness INTRODUCTION restricted to the Eucalyptus spp. plantation? How similar are the residual forests, the residual forest edge and the Eucalyptus spp. plantations have become an Eucalyptus spp. plantation? How are Lepidoptera pest important component of the Atlantic Forest region of Brazil species distributed throughout residual forests and in recent years.

  • The Saturniidae of the Loreto Road, Napo Province, Ecuador (Lepidoptera) by Luigi Racheli 1 & T Ommaso Racheli
    -1 6 3 - The Saturniidae of the Loreto Road, Napo Province, Ecuador (Lepidoptera) by Luigi Racheli 1 & T ommaso Racheli Abstract Seventy five taxa of Saturniidae along the Loreto road, Napo province, Ecuador were surveyed. Data on the phenology, species richness and biogeographical information on the recorded taxa are re­ ported. Pattern of coloration of male specimens of Eacles masoni and Eacles ormondei is discussed. Elusive species such as Rhescyntis descimoni Lemaire , 1975, Rachesa adusta (Rothschild , 1907) and Hylesiopsis festiva Bouvier , 1929 were collected in the study area. Introduction During the last years, many papers on the Ecuadorian Saturniidae were published by various authors (Lemaire , 1977; Lemaire & V enedictoff , 1989; Lemaire & T erral , 1994; Racheli , 1994, 1995a, 1995b; Racheli & R acheli , 1997). Actually, the Ecuadorian Saturniid fauna (275 species) is one of the best known in the Neotropical region (Racheli & R acheli , 1998). Faunistic studies on the Saturniidae of restricted areas in the Neotropical region are very scarce. The recent papers on the Mexican, Costarican and Peruvian Saturniidae are the only isolated examples (Beutelspacher 1978, 1982a, 1982b, 1986; Janzen , 1982, 1984, 1986; Lamas , 1989). According to Clench (1979), faunistic lists are of great importance for several aspects. Ecological and biological data are often included in this kind of studies, and these constitute basic information for further researches on taxonomy, zoogeography, ecology and conservation. From a recent study carried out on an Ecuadorian locality, Misahualli in the Napo province, a total of 92 species of Saturniidae, 33 % of the total Ecuadorian Saturniid fauna, were recorded (Racheli , 1995c; Racheli & R acheli 1998).

Alessandro Bione TUTORE COORDINATORE Dott. Antonio Martini Chiar.mo Prof. PIERO BARONIO Dipartimento di Scienze e Tecnologie Dipartimento di Scienze e Tecnologie Agroambientali Agroambientali Esame Finale anno 2010 Noi siamo un sottile strato di muschio su un masso voluminoso. Siamo un piccolo fenomeno biologico che produce parole, pensieri, e bambini, ma non arriviamo neanche a solleticare le piante dei piedi al pianeta. Kary Mullis ABSTRACT Il ginandromorfismo è il fenomeno per il quale un organismo manifesta contemporaneamente caratteristiche fenotipiche maschili e femminili. Per quanto riguarda la Classe degli Insetti, numerose segnalazioni di tale manifestazione sono reperibili in letteratura, ma un’ interpretazione generale sulle origini e sulle cause che la generano non è ancora stata fornita. Lo scopo di questa tesi è stato quello di studiare il fenomeno per quanto riguarda l’Imenottero Diprionide Diprion pini (Linnaeus, 1758) attraverso l’allevamento controllato dell’insetto, esperimenti di inincrocio, studio del cariotipo e la valutazione della comparsa e la distribuzione dei tessuti maschili e femminili negli individui ginandromorfi. Altri parametri biologici (quali i pesi degli individui) sono stati presi in considerazione nel tentativo di fornire una spiegazione riguardo i meccanismi genetici che regolano la determinazione del sesso in questa specie. Parole chiave: Ginandromorfismo, Diprion pini , inincrocio, cariotipo, determinazione del sesso. Gynandromorphism is the phenomenon by which an organism manifests phenotypic characteristics both male and female.
