ADLARD, BARTHOLOMEW CLOSE. 7U62UG9901 ; PEEFACE. On introducing this concluding volume to the reader, I tender my sincere thanks to the Members of the Council of the Ray Society for undertaking the publication of my Monograph, and for the courtesy which they have shown me in fulfilling my wishes as to the form it should assume. Prof. Helmholtz well remarks that " The materials of a monograph must be united by a logical process and the first step is to connect like with like, and to elaborate a general conception embracing them all." Again, elsewhere, "A digest or catalogue may be likened to a good lexicon ; with which almost a tyro of the present day can achieve results in the interpretation of the classics, which an Erasmus, with the erudition of a lifetime, could hardly attain." Some may perchance think that this Monograph has attained proportions unnecessarily large. The general reader, on the one hand, may take exception to its detail. The competent biologist, with more truth perhaps, may complain of omissions as well as com- missions. The first may call to remembrance and apply the causticity of Montaigne when he says, " The trade of the rhetorician is to make things appear and : VI PKEFACE. seem great, just as a shoemaker can make great shoes for little feet." An attempt has been made so to blend the life-history of Aphides with their morphology, as to render the subject not wholly uninteresting to the general reader, and yet to furnish details necessary for the systematist but the latter may reasonably ask that the facts shall not be put before him in a form unnecessarily dry. The depths of Biology are as unfathomable as those of any other science. The long list of authors I furnish at the end of this volume, though far from exhaustive, will show how much attention has been already paid to this group of insects ; and yet I am sensible of many omissions, and that much has yet to be discovered with reference to my subject. It would almost seem that more may be written on this one single insect family than on the life-history of a family of the carnivorous Vertebrata ; —we may instance the Felida3. Indeed, several years' study is required to pro- duce a complete life-history of some insects, and they may require special treatises to exhaust the subject. Through the kindness of M. J. Lichtenstein, I am enabled to give a short but compendious history of the grape-vine pest, Phylloxera vastatrix. His researches and familiarity with the whole tribe will make his observations acceptable to all. Although not strictly within the province of a treatise on British Aphides, a chapter has been devoted to the question of the general existence of Aphides in early geological times. The author has freely consulted several important memoirs of Prof. Oswald Heer, and also his valuable treatise on the ' Primeval World of Switzerland.' .Much help lias likewise been obtained PREFACE. Vll from Mr. Samuel Scudder's numerous published papers on Fossil Insects; particularly from those sections bearing on the fossil Aphides found in the beds of the Florissant basin of Colorado. This gentleman has most liberally allowed me to draw from some of his plates which have not yet been published. Although these forms are American, they have characters almost identical with our recent European genera. To these sections I have also added a short account of some of the Aphides which have been included in masses of amber. The author trusts that the preliminary remarks of this and the preceding volumes will be a sufficient acknowledgment of the sources from which much of his information has been drawn. Towards the close of this volume I have thrown together some of the principal known facts relating to the reproduction and embryology of Aphis ; and by way of introducing this subject, I have attempted a sketch bearing on the general growth of the ovum of insects. I wish here to acknowledge my indebtedness to the works of Dr. Allen Thomson, Professors Huxley, Forster, and Balfour, Ray Lankester, Ernst Haeckel, Dr. A. Brandt, E. Balbiani, and others. The late Prof. Balfour's recent treatise on ' Comparative Embryology ' is a mine of wealth to all biologists. In my former volumes I expressed, as strongly as I was able, my obligations to many friends ; and I will not here repeat my thanks. One gratification in the study and illustration of natural phenomena is a con- tinual growth of genial correspondence with those of kindred thoughts and tastes. I must here, specially offer my thanks to Prof. Vlll PREFACE. Huxley, who kindly made some valuable criticisms on reading my proofs on the ' Morphology and ; Reproduction of Aphis ' and also to Prof. Thomas Wiltshire and Prof. Rupert Jones, both of whom have suggestively helped me to get all my four volumes through the press. The subscripture to the Greek verse on my title page is very obscure : and it will invite and test the ingenuity of many, as to whether the author be ancient or modern. Recently I have received from an anonymous writer, who shrouds himself in euphonious but somewhat " stiff " Greek, a witty suggestion as to the vexed derivation of Linneus' word Aphis. It may be fairly inferred that both these effusions are the product of the same, or of kindred spirits.

  • 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).

  • POPULATION DYNAMICS of the SYCAMORE APHID (Drepanosiphum Platanoidis Schrank)
    POPULATION DYNAMICS OF THE SYCAMORE APHID (Drepanosiphum platanoidis Schrank) by Frances Antoinette Wade, B.Sc. (Hons.), M.Sc. A thesis submitted for the degree of Doctor of Philosophy of the University of London, and the Diploma of Imperial College of Science, Technology and Medicine. Department of Biology, Imperial College at Silwood Park, Ascot, Berkshire, SL5 7PY, U.K. August 1999 1 THESIS ABSTRACT Populations of the sycamore aphid Drepanosiphum platanoidis Schrank (Homoptera: Aphididae) have been shown to undergo regular two-year cycles. It is thought this phenomenon is caused by an inverse seasonal relationship in abundance operating between spring and autumn of each year. It has been hypothesised that the underlying mechanism of this process is due to a plant factor, intra-specific competition between aphids, or a combination of the two. This thesis examines the population dynamics and the life-history characteristics of D. platanoidis, with an emphasis on elucidating the factors involved in driving the dynamics of the aphid population, especially the role of bottom-up forces. Manipulating host plant quality with different levels of aphids in the early part of the year, showed that there was a contrast in aphid performance (e.g. duration of nymphal development, reproductive duration and output) between the first (spring) and the third (autumn) aphid generations. This indicated that aphid infestation history had the capacity to modify host plant nutritional quality through the year. However, generalist predators were not key regulators of aphid abundance during the year, while the specialist parasitoids showed a tightly bound relationship to its prey. The effect of a fungal endophyte infecting the host plant generally showed a neutral effect on post-aestivation aphid dynamics and the degree of parasitism in autumn.

  • Aspects of the Biology and Taxonomy of British Myrmecophilous Root Aphids
    Aspects of the biology and taxonomy of British myrmecophilous root aphids. by Richard George PAUL, BoSc.(Lond.),17.90.(Glcsgow). Thesis submitted for the Degree of Doctor of Philosopk,. of the University of London and for the Diploma of Imperial Colleao Decemi)or 1977. Dopartaent o:vv. .;:iotory)c Cromwell Road. 1.0;AMOH )t=d41/: -1- ABSTRACT. This thesis concerns the biology and taxonomy of root feeding aphids associated with British ants. A root aphid for the purposes of this thesis is defined as an aphid which, during at least part of its life cycle feeds either (a) beneath the normal soil surface or (b) beneath a tent of soil that has been placed over it by ants. The taxonomy of the genera Paranoecia and Anoecia has been revised and some synonomies proposed. Chromosome numbers have been discovered for Anoecia spp. and are used to clarify the taxonomy. The biology of Anoecia species has been studied and new facts about their life cycles have been discovered. A key is given to the British r European, African and North American species of Anoeciinae and this is included in a key to British myrmecophilous root aphids. Suction trap catches (1968-1976) from about twenty British traps have been used as a record of seasonal flight patterns for root aphids. All the Anoecia species caught in 1975 and 1976 were identified on the basis of new taxonomic work. Catches which had formerly all been identified as Anoecia corni were found to be A. corni, A. varans and A. furcata. The information derived from the catches was used to plot relative abundance and distribution maps for the three species.

  • Aphid–Plant–Phytovirus Pathosystems: Influencing Factors from Vector Behaviour to Virus Spread
    agriculture Review Aphid–Plant–Phytovirus Pathosystems: Influencing Factors from Vector Behaviour to Virus Spread Junior Corneille Fingu-Mabola * and Frédéric Francis Entomologie Fonctionnelle et Évolutive, Terra, Gembloux Agro-Bio Tech, Liège-Université, Passage des Déportés 2, 5030 Gembloux, Belgium; [email protected] * Correspondence: jcfi[email protected] Abstract: Aphids are responsible for the spread of more than half of the known phytovirus species. Virus transmission within the plant–aphid–phytovirus pathosystem depends on vector mobility which allows the aphid to reach its host plant and on vector efficiency in terms of ability to transmit phytoviruses. However, several other factors can influence the phytoviruses transmission process and have significant epidemiological consequences. In this review, we aimed to analyse the aphid behaviours and influencing factors affecting phytovirus spread. We discussed the impact of vector host-seeking and dispersal behaviours mostly involved in aphid-born phytovirus spread but also the effect of feeding behaviours and life history traits involved in plant–aphid–phytovirus relationships on vector performances. We also noted that these behaviours are influenced by factors inherent to the interactions between pathosystem components (mode of transmission of phytoviruses, vector efficiency, plant resistance, ... ) and several biological, biochemical, chemical or physical factors related to the environment of these pathosystem components, most of them being manipulated as means to control vector-borne diseases in the crop fields.
