Cepeda Museo Entomológico Luis Peña, Departamento de Sanidad Vegetal Universidad de Chile Casilla 1004, Santiago, Chile [email protected] Abstract. A new genus and species of Yponomeutidae (Lepidoptera: Yponomeutoidea) from Chile, Chileporter huemeri n. gen. and n. sp., is described based on adults, larvae and pupae. This is the second record of a specific herbivore associated with Maytenus boaria Molina. Key words. Yponomeutinae, Zelleria, Neotropical, taxonomy, chaetotaxy. Resumen. Se describe un nuevo género y especie de Yponomeutidae (Lepidoptera: Yponomeutoidea) de Chile, Chileporter huemeri n. gen. y n. sp., basado en caracteres morfológicos del adulto, larva y pupa. Este corresponde al segundo registro de un herbívoro específico asociado aMaytenus boaria Molina. Palabras clave. Yponomeutinae, Zelleria, Neotropical, taxonomía, quetotaxia. Introduction The moths in the family Yponomeutidae usually have the following combination of diagnostic morphological characters: ocellus absent, galea elongated, forewing elongated oval, labial palpus never recurved, male with pleural expansions of abdominal segment 8, abdominal terga with spines, sternum 2 of tineoid type, larvae with group L trisetose on prothorax, and pupae lacking abdominal dorsal spines (Dugdale et al. 1998; Gershenson and Ulenberg 1998). The family Yponomeutidae is poorly known from the Neotropical region; comprising less than 6% of total known species (Lewis and Sohn 2015). In Chile, the family is represented by one species, Kessleria ematynus Cepeda. This species is associated with Maytenus boaria Molina (Celastraceae); but the immature stages have not been described (Cepeda 2016). The purpose of this paper is to describe a new genus and species of Yponomeutidae from Chile, which is also associated with M. boaria. This includes figures of male and female genitalia and a description of the immature stages. Natural history observations of its development on the host are provided. The new genus is compared with three genera that are thought to be closely related, based on morphological similarities: Zelleria Stainton, Kessleria Nowicki and Paradoxus Stainton. Materials and Methods The specimens examined in this study, including permanent slides, are deposited in: MEUC Luis Peña Entomology Museum Department of Plant Protection, College of Agronomic Sciences, University of Chile, Santiago. TLMF Tiroler Landesmuseum Ferdinandeum. Innsbruck, Austria. USNM National Museum of Natural History, Smithsonian Institution, Washington, D.C., USA. ZMUC Zoological Museum University of Copenhagen, Denmark. In September and November of 2016 and 2017, larvae and pupae were collected from the host M. boaria, in Metropolitan Region, Chile. The material was separated into two groups, one for studies of immature stages and another to be reared in the laboratory until emergence of adults. Adult specimens deposited in the MEUC collection from previous rearing were also included. The larval integument was 2 • INSECTA MUNDI 0647, July 2018 CEPEDA examined using the methodology of Cepeda and Cubillos (2011). Terms for larvae and pupae follow MacKay (1972), Heppner (1987), Vargas (2007) and Patočka (1997). The adult descriptions follow Cepeda (2016). A Leitz 50× stereoscopic magnifier was used to observe the adults. A Leica DM500 microscope was used to observe the genitalia, and the photographs were taken with a 14 megapixel resolution Fujifilm HD Movie digital camera. The photographs and drawings were processed using Adobe Photoshop CS5.1. Results Chileporter Cepeda, new genus Type species. Chileporter huemeri Cepeda, new species. Diagnosis. (Fig. 1–5). Chileporter n. gen. can be separated from other yponomeutids by morphological characters of the male and female genitalia. The male differs by the absence of the cornuti and by the unique shape of the uncus, socii, and gnathos, and the female differs by the form of the corpus bursae and signum. Also, the forewing lacks a pterostigma and has an open discal cell, and the hindwing has veins M3+CuA1 not at a right angle with M1, and vein A3 absent. This genus is likely in a clade with the yponomeutid genera

SELF-REPAIR AND SELF-CLEANING OF THE LEPIDOPTERAN PROBOSCIS A Dissertation Presented to the Graduate School of Clemson University In Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy ENTOMOLOGY by Suellen Floyd Pometto August 2019 Accepted by: Dr. Peter H. Adler, Major Advisor and Committee Co-Chair Dr. Eric Benson, Committee Co-Chair Dr. Richard Blob Dr. Patrick Gerard i ABSTRACT The proboscis of butterflies and moths is a key innovation contributing to the high diversity of the order Lepidoptera. In addition to taking nectar from angiosperm sources, many species take up fluids from overripe or sound fruit, plant sap, animal dung, and moist soil. The proboscis is assembled after eclosion of the adult from the pupa by linking together two elongate galeae to form one tube with a single food canal. How do lepidopterans maintain the integrity and function of the proboscis while foraging from various substrates? The research questions included whether lepidopteran species are capable of total self- repair, how widespread the capability of self-repair is within the order, and whether the repaired proboscis is functional.

    SYSTEMATICS OF THE MEGADIVERSE SUPERFAMILY GELECHIOIDEA (INSECTA: LEPIDOPTEA) DISSERTATION Presented in Partial Fulfillment of the Requirements for The Degree of Doctor of Philosophy in the Graduate School of The Ohio State University By Sibyl Rae Bucheli, M.S. ***** The Ohio State University 2005 Dissertation Committee: Approved by Dr. John W. Wenzel, Advisor Dr. Daniel Herms Dr. Hans Klompen _________________________________ Dr. Steven C. Passoa Advisor Graduate Program in Entomology ABSTRACT The phylogenetics, systematics, taxonomy, and biology of Gelechioidea (Insecta: Lepidoptera) are investigated. This superfamily is probably the second largest in all of Lepidoptera, and it remains one of the least well known. Taxonomy of Gelechioidea has been unstable historically, and definitions vary at the family and subfamily levels. In Chapters Two and Three, I review the taxonomy of Gelechioidea and characters that have been important, with attention to what characters or terms were used by different authors. I revise the coding of characters that are already in the literature, and provide new data as well. Chapter Four provides the first phylogenetic analysis of Gelechioidea to include molecular data. I combine novel DNA sequence data from Cytochrome oxidase I and II with morphological matrices for exemplar species. The results challenge current concepts of Gelechioidea, suggesting that traditional morphological characters that have united taxa may not be homologous structures and are in need of further investigation. Resolution of this problem will require more detailed analysis and more thorough characterization of certain lineages. To begin this task, I conduct in Chapter Five an in- depth study of morphological evolution, host-plant selection, and geographical distribution of a medium-sized genus Depressaria Haworth (Depressariinae), larvae of ii which generally feed on plants in the families Asteraceae and Apiaceae.

  • Molecular Characterization of Fall Armyworm (Spodoptera Frugiperda) Resistant to Vip3aa20 Protein Expressed in Corn
    Molecular Characterization of Fall Armyworm (Spodoptera frugiperda) Resistant to Vip3Aa20 Protein Expressed in Corn Dissertation Presented in partial fulfillment of the requirements for the degree of doctor of philosophy in the Graduate School of The Ohio State University Julio Cesar Fatoretto, B. Sc. Graduate Program in Translational Plant Science The Ohio State University 2017 Dissertation Committee: Andrew P. Michel, Advisor Marcio C. Silva Filho Thomas Mitchell Fernando Consoli Copyright by Julio Cesar Fatoretto 2017 Abstract Transgenic plants containing genes from Bacillus thuringiensis have been used as an alternative to chemical insecticides for insect pest control. The vegetative insecticidal proteins (Vip) secreted during the vegetative growth phase of bacteria are considered a second generation of insecticidal proteins since they do not share any structural or sequence homology with previously used crystal proteins (Cry) as well as having a wide insecticidal spectrum. One of the target pests for this protein is the fall armyworm (FAW) (Spodoptera frugiperda), the most important corn pest in South America. Previously it has been controlled by insecticides and corn expressing Cry proteins, but has rapidly evolved resistance to many control practices and remains a top concern for sustainable biotechnology control efforts. Thus, resistance characterization involving mode of action and genetics of resistance can help with Insect Resistance Management strategies, and improve the durability of control. In this dissertation, using selected FAW population resistant to Vip3Aa20 Bt protein (Vip-R1and Vip-R2) we generated comparative proteomic and transcriptomic data among resistant and susceptible colonies. In the chapter 2, we bring FAW biology/ecology and Brazilian agriculture landscape data to support the high adaptive potential of this pest to genetically modified corn expressing Bt Cry proteins in Brazil.

  • Acoustic Communication in the Nocturnal Lepidoptera
    Chapter 6 Acoustic Communication in the Nocturnal Lepidoptera Michael D. Greenfield Abstract Pair formation in moths typically involves pheromones, but some pyra- loid and noctuoid species use sound in mating communication. The signals are generally ultrasound, broadcast by males, and function in courtship. Long-range advertisement songs also occur which exhibit high convergence with commu- nication in other acoustic species such as orthopterans and anurans. Tympanal hearing with sensitivity to ultrasound in the context of bat avoidance behavior is widespread in the Lepidoptera, and phylogenetic inference indicates that such perception preceded the evolution of song. This sequence suggests that male song originated via the sensory bias mechanism, but the trajectory by which ances- tral defensive behavior in females—negative responses to bat echolocation sig- nals—may have evolved toward positive responses to male song remains unclear. Analyses of various species offer some insight to this improbable transition, and to the general process by which signals may evolve via the sensory bias mechanism. 6.1 Introduction The acoustic world of Lepidoptera remained for humans largely unknown, and this for good reason: It takes place mostly in the middle- to high-ultrasound fre- quency range, well beyond our sensitivity range. Thus, the discovery and detailed study of acoustically communicating moths came about only with the use of electronic instruments sensitive to these sound frequencies. Such equipment was invented following the 1930s, and instruments that could be readily applied in the field were only available since the 1980s. But the application of such equipment M. D.

  • Non-Expressway Master Plant List
    MASTER PLANT LIST GENERAL INTRODUCTION TO PLANT LISTS Plants are living organisms. They possess variety in form, foliage and flower color, visual texture and ultimate size. There is variation in plants of the same species. Plants change: with seasons, with time and with the environment. Yet here is an attempt to categorize and catalogue a group of plants well suited for highway and expressway planting in Santa Clara County. This is possible because in all the existing variety of plants, there still remains a visual, morphological and taxonomical distinction among them. The following lists and identification cards emphasize these distinctions. 1 of 6 MASTER PLANT LIST TREES Acacia decurrens: Green wattle Acacia longifolia: Sydney golden wattle Acacia melanoxylon: Blackwood acacia Acer macrophyllum: Bigleaf maple Aesculus californica: California buckeye Aesculus carnea: Red horsechestnut Ailanthus altissima: Tree-of-heaven Albizia julibrissin: Silk tree Alnus cordata: Italian alder Alnus rhombifolia: White alder Arbutus menziesii: Madrone Calocedrus decurrens: Incense cedar Casuarina equisetifolia: Horsetail tree Casuarina stricta: Coast beefwood Catalpa speciosa: Western catalpa Cedrus deodara: Deodar cedar Ceratonia siliqua: Carob Cinnamomum camphora: Camphor Cordyline australis: Australian dracena Crataegus phaenopyrum: Washington thorn Cryptomeria japonica: Japanese redwood Cupressus glabra: Arizona cypress Cupressus macrocarpa: Monterey cypress Eriobotrya japonica: Loquat Eucalyptus camaldulensis: Red gum Eucalyptus citriodora: Lemon-scented

  • Thuja (Arborvitae)
    nysipm.cornell.edu 2019 Search for this title at the NYSIPM Publications collection: ecommons.cornell.edu/handle/1813/41246 Disease and Insect Resistant Ornamental Plants Mary Thurn, Elizabeth Lamb, and Brian Eshenaur New York State Integrated Pest Management Program, Cornell University Thuja Arborvitae Thuja is a genus of evergreens commonly known as arborvitae. Used extensively in ornamental plantings, there are numerous cultivars available for a range of size, form and foliage color. Many can be recognized by their distinctive scale-like foliage and flattened branchlets. Two popular species, T. occidentalis and T. plicata, are native to North America. Insect pests include leafminers, spider mites and bagworms. Leaf and tip blights may affect arbor- vitae in forest, landscape and nursery settings. INSECTS Arborvitae Leafminer, Argyresthia thuiella, is a native insect pest of Thuja spp. While there are several species of leafminers that attack arborvitae in the United States, A. thuiella is the most common. Its range includes New England and eastern Canada, south to the Mid-Atlantic and west to Missouri (5). Arborvitae is the only known host (6). Heavy feeding in fall and early spring causes yellow foliage that later turns brown. Premature leaf drop may follow. Plants can survive heavy defoliation, but their aesthetic appeal is greatly diminished. Re­ searchers at The Morton Arboretum report significant differences in relative susceptibility to feeding by arborvitae leafminer for several Thuja species and cultivars.

Patterns of flammability across the vascular plant phylogeny, with special emphasis on the genus Dracophyllum A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of philosophy at Lincoln University by Xinglei Cui Lincoln University 2020 Abstract of a thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of philosophy. Abstract Patterns of flammability across the vascular plant phylogeny, with special emphasis on the genus Dracophyllum by Xinglei Cui Fire has been part of the environment for the entire history of terrestrial plants and is a common disturbance agent in many ecosystems across the world. Fire has a significant role in influencing the structure, pattern and function of many ecosystems. Plant flammability, which is the ability of a plant to burn and sustain a flame, is an important driver of fire in terrestrial ecosystems and thus has a fundamental role in ecosystem dynamics and species evolution. However, the factors that have influenced the evolution of flammability remain unclear.
