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 Auricle Moray Beekeepers Association Newsletter Hot off the ‘press’ Au gust Issue No: 5/09 T HIS MONTH’S NEWSLETTER IS ANONYMOUSLY SPONSORED BY AN M.B.A. MEMBER – THANK YOU! ‘I’M A BEEKEEPER, GET ME OUT OF HERE!!!’ Approximately 30 members attended the August meeting at Andrew Tassell’s apiary in Fochabers and those who managed to forge the swollen burn, scramble up the muddy bank, overcome the assault course and navigate through the ‘jungle’ enjoyed an informative talk and demonstration by Andrew entitled, ‘Preparing Bees for the Heather.’ Heather honey is the ‘Rolls Royce’ of honey and Scottish heather honey is much sought after demanding premium prices so it is worth making the effort to get some, particularly as most of us live within easy reach of the heather. Andrew demonstrating how to secure a hive watched by MBA member Adrian Wardlaw Andrew moves his best hives to the heather during the last weekend of July for about five weeks and if the heather secretes nectar for a couple of weeks there should be at least one super of honey on each hive. Hives for the heather should be absolutely packed full with bees so Andrew adds up to 2 frames of emerging brood from another disease free hive a couple of weeks before the move. Other tips include moving frames of eggs and brood to the outside of the brood frame and frames of honey to the centre. As the bees usually like to store honey in the outside frames, leaving the centre frames for the queen to lay in, they usually move this honey to a super, and this should be done a couple of weeks before and then again a couple of days before the move. -

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. -
Native and Invasive Ants Affect Floral Visits of Pollinating Honey Bees in Pumpkin Flowers (Cucurbita Maxima)
www.nature.com/scientificreports OPEN Native and invasive ants afect foral visits of pollinating honey bees in pumpkin fowers (Cucurbita maxima) Anjana Pisharody Unni1,3, Sajad Hussain Mir1,2, T. P. Rajesh1, U. Prashanth Ballullaya1, Thomas Jose1 & Palatty Allesh Sinu1* Global pollinator decline is a major concern. Several factors—climate change, land-use change, the reduction of fowers, pesticide use, and invasive species—have been suggested as the reasons. Despite being a potential reason, the efect of ants on fowers received less attention. The consequences of ants being attracted to nectar sources in plants vary depending upon factors like the nectar source’s position, ants’ identity, and other mutualists interacting with the plants. We studied the interaction between fower-visiting ants and pollinators in Cucurbita maxima and compared the competition exerted by native and invasive ants on its pollinators to examine the hypothesis that the invasive ants exacerbate more interference competition to pollinators than the native ants. We assessed the pollinator’s choice, visitation rate, and time spent/visit on the fowers. Regardless of species and nativity, ants negatively infuenced all the pollinator visitation traits, such as visitation rate and duration spent on fowers. The invasive ants exerted a higher interference competition on the pollinators than the native ants did. Despite performing pollination in fowers with generalist pollination syndrome, ants can threaten plant-pollinator mutualism in specialist plants like monoecious plants. A better understanding of factors infuencing pollination will help in implementing better management practices. Humans brought together what continents isolated. One very conspicuous evidence of this claim rests in the rearranged biota. -

Nielsen Ph.D. Committee Member Associate Professor Department of Biology ii © Copyright by Stephanie Kay Gunter All rights reserved 2021 iii ABSTRACT CAN THE ONE TRUE BUG BE THE ONE TRUE ANSWER? THE INFLUENCE OF PRAIRIE RESTORATION ON HEMIPTERA COMPOSITION Name: Gunter, Stephanie Kay University of Dayton Advisor: Dr. Chelse M. Prather Ohio historically hosted a patchwork of tallgrass prairies, which provided habitat for native species and prevented erosion. As these vulnerable habitats have declined in the last 200 years due to increased human land use, restorations of these ecosystems have increased, and it is important to evaluate their success. The Hemiptera (true bugs) are an abundant and varied order of insects including leafhoppers, aphids, cicadas, stink bugs, and more. They play important roles in grassland ecosystems, feeding on plant sap and providing prey to predators. Hemipteran abundance and composition can respond to grassland restorations, age of restoration, and size and isolation of habitat. -
A New Pupillarial Scale Insect (Hemiptera: Coccoidea: Eriococcidae) from Angophora in Coastal New South Wales, Australia

WILLIAMS2 1Division of Evolution, Ecology & Genetics, Research School of Biology, The Australian National University, Acton, Canberra, A.C.T. 2601, Australia 2The Natural History Museum, Department of Life Sciences (Entomology), London SW7 5BD, UK 3Corresponding author. 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. -
Colour Transcript
Colour Transcript Date: Wednesday, 30 March 2011 - 6:00PM Location: Museum of London 30 March 2011 Colour Professor William Ayliffe Some of you in this audience will be aware that it is the 150th anniversary of the first colour photograph, which was projected at a lecture at the Royal Institute by James Clerk Maxwell. This is the photograph, showing a tartan ribbon, which was taken using the first SLR, invented by Maxwell’s friend. He took three pictures, using three different filters, and was then able to project this gorgeous image, showing three different colours for the first time ever. Colour and Colour Vision This lecture is concerned with the questions: “What is colour?” and “What is colour vision?” - not necessarily the same things. We are going to look at train crashes and colour blindness (which is quite gruesome); the antique use of colour in pigments – ancient red Welsh “Ladies”; the meaning of colour in medieval Europe; discovery of new pigments; talking about colour; language and colour; colour systems and the psychology of colour. So there is a fair amount of ground to cover here, which is appropriate because colour is probably one of the most complex issues that we deal with. The main purpose of this lecture is to give an overview of the whole field of colour, without going into depth with any aspects in particular. Obviously, colour is a function of light because, without light, we cannot see colour. Light is that part of the electromagnetic spectrum that we can see, and that forms only a tiny portion. -

Wetlands Invertebrates Banded Woollybear(Isabella Tiger Moth Larva)
Wetlands Invertebrates Banded Woollybear (Isabella Tiger Moth larva) basics The banded woollybear gets its name for two reasons: its furry appearance and the fact that, like a bear, it hibernates during the winter. Woollybears are the caterpillar stage of medium sized moths known as tiger moths. This family of moths rivals butterflies in beauty and grace. There are approximately 260 species of tiger moths in North America. Though the best-known woollybear is the banded woollybear, there are at least 8 woollybear species in the U.S. with similar dense, bristly hair covering their bodies. Woollybears are most commonly seen in the autumn, when they are just about finished with feeding for the year. It is at this time that they seek out a place to spend the winter in hibernation. They have been eating various green plants since June or early July to gather enough energy for their eventual transformation into butterflies. A full-grown banded woollybear caterpillar is nearly two inches long and covered with tubercles from which arise stiff hairs of about equal length. Its body has 13 segments. Middle segments are covered with red-orange hairs and the anterior and posterior ends with black hairs. The orange-colored oblongs visible between the tufts of setae (bristly hairs) are spiracles—entrances to the respiratory system. Hair color and band width are highly variable; often as the caterpillar matures, black hairs (especially at the posterior end) are replaced with orange hairs. In general, older caterpillars have more black than young ones. However, caterpillars that fed and grew in an area where the fall weather was wetter tend to have more black hair than caterpillars from dry areas. -

A new genus and species, Yuripopovina magnifica, belonging to a new coreoid family, Yuripopovinidae (Hemiptera: Pentatomomorpha), is described and illustrated from the Lower Cretaceous amber of Lebanon. The species represents the first definitive Mesozoic record for the Coreoidea. A cladistic analysis of Coreoidea, including the new family, is undertaken. KEY WORDS: Pentatomomorpha, Coreoidea, Yuripopovinidae, fam. n., gen. n., sp. n., Lebanon, phylogeny. INTRODUCTION The Pentatomomorpha with its 14 000 known living species (WEIRAUCH & SCHUH 2011) is the second largest of the seven heteropteran infraorders (SCHAEFER 1993, ŠTYS & KERZHNER 1975) (Enicocephalomorpha, Dipsocoromorpha, Gerromorpha, Nepomorpha, Leptodomorpha, Cimicomorpha, and Pentatomorpha). Most authors recognize five superfamilies within Pentatomomorpha, but there remains controversy regarding the 628 Polish Journal of Entomology 80 (4) composition of these superfamilies (SCHAEFER 1993, ŠTYS 1961).
