  • Morphology and Adaptation of Immature Stages of Hemipteran Insects
    © 2019 JETIR January 2019, Volume 6, Issue 1 www.jetir.org (ISSN-2349-5162) Morphology and Adaptation of Immature Stages of Hemipteran Insects Devina Seram and Yendrembam K Devi Assistant Professor, School of Agriculture, Lovely Professional University, Phagwara, Punjab Introduction Insect Adaptations An adaptation is an environmental change so an insect can better fit in and have a better chance of living. Insects are modified in many ways according to their environment. Insects can have adapted legs, mouthparts, body shapes, etc. which makes them easier to survive in the environment that they live in and these adaptations also help them get away from predators and other natural enemies. Here are some adaptations in the immature stages of important families of Hemiptera. Hemiptera are hemimetabolous exopterygotes with only egg and nymphal immature stages and are divided into two sub-orders, homoptera and heteroptera. The immature stages of homopteran families include Delphacidae, Fulgoridae, Cercopidae, Cicadidae, Membracidae, Cicadellidae, Psyllidae, Aleyrodidae, Aphididae, Phylloxeridae, Coccidae, Pseudococcidae, Diaspididae and heteropteran families Notonectidae, Corixidae, Belastomatidae, Nepidae, Hydrometridae, Gerridae, Veliidae, Cimicidae, Reduviidae, Pentatomidae, Lygaeidae, Coreidae, Tingitidae, Miridae will be discussed. Homopteran families 1. Delphacidae – Eg. plant hoppers They comprise the largest family of plant hoppers and are characterized by the presence of large, flattened spurs at the apex of their hind tibiae. Eggs are deposited inside plant tissues, elliptical in shape, colourless to whitish. Nymphs are similar in appearance to adults except for size, colour, under- developed wing pads and genitalia. 2. Fulgoridae – Eg. lantern bugs They can be recognized with their antennae inserted on the sides & beneath the eyes.

The neococcoids form a mono- phyletic group supported by both morphological and genetic data. In contrast, the monophyly of the archaeococcoids is uncertain and the higher level ranks within it have been controversial, particularly since the late Professor Jan Koteja introduced his multi-family classification for scale insects in 1974. Recent phylogenetic studies using molecular and morphological data support the recognition of up to 15 extant families of archaeococcoids, including 11 families for the former Margarodidae sensu lato, vindicating Koteja’s views. Archaeococcoids are represented better in the fossil record than neococcoids, and have an adequate record through the Tertiary and Cretaceous but almost no putative coccoid fos- sils are known from earlier.

  • San Jose Scale and Its Natural Enemies: Investigating Natural Or Augmented Controls
    California Tree Fruit Agreement Research Report 2002 SAN JOSE SCALE AND ITS NATURAL ENEMIES: INVESTIGATING NATURAL OR AUGMENTED CONTROLS Project Leaders: Kent M. Daane Cooperators: Glenn Y. Yokota, Walter J. Bentley, Karen Sime, and Brian Hogg ABSTRACT San Jose scale (SJS) and its natural enemies were studied from 1999 through 2002. Natural populations were followed in stone fruit and almond blocks, with orchard management practices divided into “conventional” and “sustainable” practices, based on dormant and in-season insecticide use. Results generally show higher fruit damage at harvest-time in sustainably managed fields, although, these results are not consistent among orchards and exceptions to this pattern were found. In conventionally managed blocks, later harvest dates resulted in higher SJS fruit damage, although this did not hold true in sustainably managed orchards. Results from SJS pheromone-baited traps show a predominant seasonal pattern of SJS densities progressively increasing and parasitoid (Encarsia perniciosi) densities progressively decreasing. These data are discussed with respect to SJS fruit damage and parasitoid establishment and efficiency. SJS and parasitoid sampling methodology and distribution were investigated. Comparing SJS pheromone trap data to numbers of crawlers on double-sided sticky tape and SJS infested fruit at harvest show a significant correlation between pheromone trap counts of SJS males and numbers of SJS crawlers. Results suggest that there is a small window in the season (April-May) when sticky tape provides important information on crawler abundance and damage. Results show a negative correlation between the early season abundance of Encarsia (as measured by pheromone traps) and SJS damage at harvest. These results suggest that early-season ratios of parasitoid : SJS can not be used to predict fruit damage or biological control (these data require more analysis).

All these species are limited to the Northern Hemisphere: many of them are distributed in eastern Asia and North America, and much fewer ones in western Asia and the Mediterranean Region. In Eurasia most species have been recorded from particular plants and many are associated with Fagaceae, while in North America polyphagy is rather prevailing and the hosts are scattered over much more diverse plants. In the number and arrangement of the modified macroducts in the 2nd instar males many eastern Asian species are uniform, while North American species show diverse patterns.

Information about the scientific collections is made available more and more often. The digitisation of such resources allows us to verify their value and share these records with other scientists – and they are usually rich in taxa and unique in the world. Moreover, such information significantly enriches local and global knowledge about biodiversi- ty. The digitisation of the resources of the Zoology Research Group, University of Silesia in Katowice (Poland) allowed presenting a substantial collection of scale insects (Hemiptera: Coccomorpha). The collection counts 9369 slide-mounted specimens, about 200 alcohol-preserved samples, close to 2500 dry specimens stored in glass vials and 1319 amber inclu- sions representing 343 taxa (289 identified to species level), 158 genera and 36 families (29 extant and seven extinct).

  • Precious but Not Precious UP-RE-CYCLING
    The sounds of ideas forming , Volume 3 Alan Dunn, 22 July 2020 presents precious but not precious UP-RE-CYCLING This is the recycle tip at Clatterbridge. In February 2020, we’re dropping off some stuff when Brigitte shouts “if you get to the plastic section sharpish, someone’s throwing out a pile of records.” I leg it round and within seconds, eyes and brain honed from years in dank backrooms and charity shops, I smell good stuff. I lean inside, grabbing a pile of vinyl and sticking it up my top. There’s compilations with Blondie, Boomtown Rats and Devo and a couple of odd 2001: A Space Odyssey and Close Encounters soundtracks. COVER (VERSIONS) www.alandunn67.co.uk/coverversions.html For those that read the last text, you’ll enjoy the irony in this introduction. This story is about vinyl but not as a precious and passive hands-off medium but about using it to generate and form ideas, abusing it to paginate a digital sketchbook and continuing to be astonished by its magic. We re-enter the story, the story of the sounds of ideas forming, after the COVER (VERSIONS) exhibition in collaboration with Aidan Winterburn that brings together the ideas from July 2018 – December 2019. Staged at Leeds Beckett University, it presents the greatest hits of the first 18 months and some extracts from that first text that Aidan responds to (https://tinyurl.com/y4tza6jq), with me in turn responding back, via some ‘OUR PRICE’ style stickers with quotes/stats. For the exhibition, the mock-up sleeves fabricated by Tom Rodgers look stunning, turning the digital detournements into believable double-sided artefacts.

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).

As principais características dos ‘Homoptera’ e dos Formicidae que favorecem as interações trofobióticas, tais como a excreção de honeydew por insetos sugadores, atendimento por formigas e necessidades fisiológicas dos dois grupos de insetos, são discutidas. Aspectos da sua evolução convergente são apresenta- dos. O sistema mais arcaico não é exatamente trofobiótico, as forrageadoras coletam o honeydew despejado ao acaso na folhagem por indivíduos ou grupos de ‘Homoptera’ não associados. As relações trofobióticas mais comuns são facultativas, no entanto, esta forma de mutualismo é extremamente diversificada e é responsável por numerosas adaptações fisiológicas, morfológicas ou comportamentais entre os ‘Homoptera’, em particular Sternorrhyncha. As trofobioses mais diferenciadas são verdadeiras simbioses onde as adaptações mais extremas são observadas do lado dos ‘Homoptera’. Ao mesmo tempo, as formigas mostram adaptações comportamentais que resultam de um longo período de coevolução. Considerando-se os inse- tos sugadores como principais pragas dos cultivos em nível mundial, as implicações das rela- ções trofobióticas são discutidas no contexto das comunidades de insetos em geral, focalizan- do os problemas que geram em Manejo Integrado de Pragas (MIP), em particular.
