E-mail: [email protected] Abstract A new scale insect, Aolacoccus angophorae gen. nov. and sp. nov. (Eriococcidae), is described from the bark of Ango- phora (Myrtaceae) growing in the Sydney area of New South Wales, Australia. These insects do not produce honeydew, are not ant-tended and probably feed on cortical parenchyma. The adult female is pupillarial as it is retained within the cuticle of the penultimate (second) instar. The crawlers (mobile first-instar nymphs) emerge via a flap or operculum at the posterior end of the abdomen of the second-instar exuviae. The adult and second-instar females, second-instar male and first-instar nymph, as well as salient features of the apterous adult male, are described and illustrated. The adult female of this new taxon has some morphological similarities to females of the non-pupillarial palm scale Phoenicococcus marlatti Cockerell (Phoenicococcidae), the pupillarial palm scales (Halimococcidae) and some pupillarial genera of armoured scales (Diaspididae), but is related to other Australian Myrtaceae-feeding eriococcids.

  • Fungi and Their Potential As Biological Control Agents of Beech Bark Disease
    Fungi and their potential as biological control agents of Beech Bark Disease By Sarah Elizabeth Thomas A thesis submitted for the degree of Doctor of Philosophy School of Biological Sciences Royal Holloway, University of London 2014 1 DECLARATION OF AUTHORSHIP I, Sarah Elizabeth Thomas, hereby declare that this thesis and the work presented in it is entirely my own. Where I have consulted the work of others, this is always clearly stated. Signed: _____________ Date: 4th May 2014 2 ABSTRACT Beech bark disease (BBD) is an invasive insect and pathogen disease complex that is currently devastating American beech (Fagus grandifolia) in North America. The disease complex consists of the sap-sucking scale insect, Cryptococcus fagisuga and sequential attack by Neonectria fungi (principally Neonectria faginata). The scale insect is not native to North America and is thought to have been introduced there on seedlings of F. sylvatica from Europe. Conventional control strategies are of limited efficacy in forestry systems and removal of heavily infested trees is the only successful method to reduce the spread of the disease. However, an alternative strategy could be the use of biological control, using fungi. Fungal endophytes and/or entomopathogenic fungi (EPF) could have potential for both the insect and fungal components of this highly invasive disease. Over 600 endophytes were isolated from healthy stems of F. sylvatica and 13 EPF were isolated from C. fagisuga cadavers in its centre of origin. A selection of these isolates was screened in vitro for their suitability as biological control agents. Two Beauveria and two Lecanicillium isolates were assessed for their suitability as biological control agents for C.

  • Insect Classification Standards 2020
    RECOMMENDED INSECT CLASSIFICATION FOR UGA ENTOMOLOGY CLASSES (2020) In an effort to standardize the hexapod classification systems being taught to our students by our faculty in multiple courses across three UGA campuses, I recommend that the Entomology Department adopts the basic system presented in the following textbook: Triplehorn, C.A. and N.F. Johnson. 2005. Borror and DeLong’s Introduction to the Study of Insects. 7th ed. Thomson Brooks/Cole, Belmont CA, 864 pp. This book was chosen for a variety of reasons. It is widely used in the U.S. as the textbook for Insect Taxonomy classes, including our class at UGA. It focuses on North American taxa. The authors were cautious, presenting changes only after they have been widely accepted by the taxonomic community. Below is an annotated summary of the T&J (2005) classification. Some of the more familiar taxa above the ordinal level are given in caps. Some of the more important and familiar suborders and families are indented and listed beneath each order. Note that this is neither an exhaustive nor representative list of suborders and families. It was provided simply to clarify which taxa are impacted by some of more important classification changes. Please consult T&J (2005) for information about taxa that are not listed below. Unfortunately, T&J (2005) is now badly outdated with respect to some significant classification changes. Therefore, in the classification standard provided below, some well corroborated and broadly accepted updates have been made to their classification scheme. Feel free to contact me if you have any questions about this classification.

A redescription and illustration of the adult female of Neoacanthococcus tamaricicola Borchsenius, 1948, are given, and a key for Tamarix- feeding eriocococids in the Palaearctic zoogeographic region is provided. Key words: Eriococcidae, Neoacanthococcus, Tamarix sp., Turkey. Anahtar sözcükler: Eriococcidae, Neoacanthococcus, Tamarix sp., Türkiye. Introduction The family Eriococcidae (felt scales) is the fourth richest, and presumably one of the oldest families of Coccoidea (Hoy, 1962, 1963; Miller & Kosztarab, 1979; Koteja, 1985; Miller & Miller, 1992; Foldi, 1997; Miller & Gimpel, 2000; Gullan & Cook, 2007). However, in comparison with most other scale insect families, our taxonomic knowledge on this family is far from complete. It has been postulated that this family or family group arose in temperate Antarctica during the Cretaceous period (Hoy, 1962) and the generic and species richness of eriococcids in the Southern Hemisphere also suggests a southern origin for the family (Williams 1984).
