Apratylenchoides joenssoni sp. nov. differs from the only other known spe- cies of Apratylenchoides, A. belli Sher, 1973, in having a pumpkin-like spermatheca, shorter dorsal gland lobe, longer tail, and crenate tail tip. Pratylenchus andinus Lordello, Zamith et Boock, 1961, Tylenchorhynchus maximus Allen, 1955, Aglenchus agricola (de Man, 1884) Meyl, 1961 and Paratylenchus nanus Cobb, 1923 were also recorded for the first time in Antarctica. The rather unexpected presence of plant parasitic nematodes in habitats devoid of vascular plants and some biogeographical implications of the findings are discussed.

  • (Pentatomidae) DISSERTATION Presented
    Genome Evolution During Development of Symbiosis in Extracellular Mutualists of Stink Bugs (Pentatomidae) DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Alejandro Otero-Bravo Graduate Program in Evolution, Ecology and Organismal Biology The Ohio State University 2020 Dissertation Committee: Zakee L. Sabree, Advisor Rachelle Adams Norman Johnson Laura Kubatko Copyrighted by Alejandro Otero-Bravo 2020 Abstract Nutritional symbioses between bacteria and insects are prevalent, diverse, and have allowed insects to expand their feeding strategies and niches. It has been well characterized that long-term insect-bacterial mutualisms cause genome reduction resulting in extremely small genomes, some even approaching sizes more similar to organelles than bacteria. While several symbioses have been described, each provides a limited view of a single or few stages of the process of reduction and the minority of these are of extracellular symbionts. This dissertation aims to address the knowledge gap in the genome evolution of extracellular insect symbionts using the stink bug – Pantoea system. Specifically, how do these symbionts genomes evolve and differ from their free- living or intracellular counterparts? In the introduction, we review the literature on extracellular symbionts of stink bugs and explore the characteristics of this system that make it valuable for the study of symbiosis. We find that stink bug symbiont genomes are very valuable for the study of genome evolution due not only to their biphasic lifestyle, but also to the degree of coevolution with their hosts. i In Chapter 1 we investigate one of the traits associated with genome reduction, high mutation rates, for Candidatus ‘Pantoea carbekii’ the symbiont of the economically important pest insect Halyomorpha halys, the brown marmorated stink bug, and evaluate its potential for elucidating host distribution, an analysis which has been successfully used with other intracellular symbionts.

New host plant and distributional records of A. bifasciata Stål are given; habitus illustrations and drawings of male and female gen- italia are included as well as a key to the known species. The group feeds on bromeli- ads. Key Words: Insecta, Heteroptera, Coreidae, Leptoscelini, Amblyomia, Bromeliaceae RESUMEN El género Amblyomia Stål es revisado y dos nuevas especies, A. foreroi y A. prome- ceops, recolectadas en Colombia, son descritas. Plantas hospederas y nuevas local- idades para A. bifasciata Stål son incluidas; se ofrece una clave para la separación de las especies conocidas, las cuales son ilustradas incluyendo los genitales de ambos sexos. Las preferencias tróficas del grupo están orientadas hacia bromelias. Palabras clave: Insecta, Heteroptera, Coreidae, Leptoscelini, Amblyomia, Bromeli- aceae The neotropical genus Amblyomia Stål was previously known from a single Mexi- can species, A. bifasciata Stål 1870. In the present paper the genus is redefined to in- clude two new species collected in Colombia. This genus apparently is restricted to feeding on members of the Bromeliaceae, and specimens were collected on the heart of Ananas comosus and Aechmea bracteata.

  • The Mechanism by Which Aphids Adhere to Smooth Surfaces
    J. exp. Biol. 152, 243-253 (1990) 243 Printed in Great Britain © The Company of Biologists Limited 1990 THE MECHANISM BY WHICH APHIDS ADHERE TO SMOOTH SURFACES BY A. F. G. DIXON, P. C. CROGHAN AND R. P. GOWING School of Biological Sciences, University of East Anglia, Norwich, NR4 7TJ Accepted 30 April 1990 Summary 1. The adhesive force acting between the adhesive organs and substratum for a number of aphid species has been studied. In the case of Aphis fabae, the force per foot is about 10/iN. This is much the same on both glass (amphiphilic) and silanized glass (hydrophobic) surfaces. The adhesive force is about 20 times greater than the gravitational force tending to detach each foot of an inverted aphid. 2. The mechanism of adhesion was considered. Direct van der Waals forces and viscous force were shown to be trivial and electrostatic force and muscular force were shown to be improbable. An adhesive force resulting from surface tension at an air-fluid interface was shown to be adequate and likely. 3. Evidence was collected that the working fluid of the adhesive organ has the properties of a dilute aqueous solution of a surfactant. There is a considerable reserve of fluid, presumably in the cuticle of the adhesive organ. Introduction The mechanism by which certain insects can walk on smooth vertical and even inverted surfaces has long interested entomologists and recently there have been several studies on this subject (Stork, 1980; Wigglesworth, 1987; Lees and Hardie, 1988). The elegant study of Lees and Hardie (1988) on the feet of the vetch aphid Megoura viciae Buckt.

  • PRA Cerataphis Lataniae
    CSL Pest Risk Analysis for Cerataphis lataniae CSL copyright, 2005 Pest Risk Analysis for Cerataphis lataniae Boisduval STAGE 1: PRA INITIATION 1. What is the name of the pest? Cerataphis lataniae (Boisduval) Hemiptera Aphididae the Latania aphid Synonyms: Ceratovacuna palmae (Baehr) Aphis palmae (Baehr) Boisduvalia lataniae (Boisduval) Note: In the past C. lataniae has been confused with both C. brasiliensis and C. orchidearum (Howard, 2001). As a result it is not always clear which of the older records for host plants and distribution refer to which species. BAYER CODES: CEATLA 2. What is the reason for the PRA? This PRA was initiated following a second interception of this species. Cerataphis lataniae was first intercepted in the UK in 1999 on a consignment of Archontophoenix alexandra and Brahea drandegai, from South Africa. Since then it has been intercepted twice more; on 30/05/02 on Cocos spp. and then again on 13/06/02 on Cocos nucifera. Both the findings in 2002 were at the same botanic garden and there is some suggestion the Coco plants were supplied by the nursery where the first interception was made in 1999. 3. What is the PRA area? As C. lataniae is present within the EU (Germany, Italy, Spain) (See point 11.) this PRA only considers the UK. STAGE 2: PEST RISK ASSESSMENT 4. Does the pest occur in the PRA area or does it arrive regularly as a natural migrant? No. Although Cerataphis lataniae is included on the British checklist this is likely to be an invalid record as there is no evidence to suggest it is established in the UK (R.

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).

Copyright 2014 Stellenbosch University All rights reserved ii Stellenbosch University http://scholar.sun.ac.za Abstract Diuraphis noxia (Kurdjumov, Hemiptera, Aphididae) commonly known as the Russian wheat aphid (RWA), is a small phloem-feeding pest of wheat (Triticum aestivum L). Virulent D. noxia biotypes that are able to feed on previously resistant wheat cultivars continue to develop and therefor the identification of factors contributing to virulence is vital. Since energy metabolism plays a key role in the survival of organisms, genes and processes involved in the production and regulation of energy may be key contributors to virulence: such as mitochondria and the NAD+/NADH that reflects the health and metabolic activities of a cell. The involvement of carotenoids in the generation of energy through a photosynthesis- like process may be an important factor, as well as its contribution to aphid immunity through mediation of oxidative stress.

The current classification includes two tribes: the Chaitophorini associated with deciduous trees and shrubs, and Siphini that feed on monocotyledonous plants. We present the first phylogenetic OPEN ACCESS hypothesis for the subfamily, based on molecular and morphological datasets. Molecular Citation: Wieczorek K, Lachowska-Cierlik D, analyses were based on the mitochondrial gene cytochrome oxidase subunit I (COI) and the Kajtoch è, Kanturski M (2017) The relationships within the Chaitophorinae and Drepanosiphinae nuclear gene elongation factor-1α (EF-1α). Phylogenetic inferences were obtained individu- (Hemiptera, Aphididae) inferred from molecular- ally on each of genes and joined alignments using Bayesian inference (BI) and Maximum based phylogeny and comprehensive likelihood (ML).

Periphyllus forms independent lineages from Chaitophorus Editor: Daniel Doucet, Natural Resources Canada, CANADA and Siphini. Within this genus two clades comprising European and Asiatic species, respec- tively, were indicated.
