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. -

These two psyllids are the only known vectors of the etiologic agent of citrus greening disease (Huanglongbing), and are the only eco- nomically important psyllid species on citrus in the world. Six other species of Diaphorina are reported on citrus, but these are non-vector species of relatively little importance (Halbert and Manjunath 2004). -

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. -

Distribution of Spiders in Coastal Grey Dunes

The knowledge of dispersal evolution, motivation, its effect on metapopulation dynamics and species distribution at multiple scales is poorly understood and many questions remain unsolved or require empirical verification. In this thesis we contribute to the knowledge of dispersal, by studying both ecological and evolutionary aspects of spider dispersal in fragmented grey dunes. Studies were performed at the individual, population and assemblage level and indicate that behavioural traits narrowly linked to dispersal, con- siderably show [adaptive] variation in function of habitat quality and geometry. Dispersal also determines spider distribution patterns and metapopulation dynamics. Consequently, our results stress the need to integrate knowledge on behavioural ecology within the study of ecological landscapes. / Promotor: Prof. Dr. Eckhart Kuijken [Ghent University & Institute of Nature Dries Bonte Conservation] Co-promotor: Prf.

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). -

The impacts of pathogen-induced plant traits on vector preference are well studied in pathosystems but not in phytoplasma pathosystems. Therefore, the study of phytoplasma pathosystems may provide important insight into controlling economically important phytoplasma related diseases. In this study, we aimed to understand the impacts of a phytoplasma disease in palms on the feeding preference of its potential vector. We investigated the effects of a palm-infecting phytoplasma, lethal bronzing (LB), on the abundance of herbivorous insects. These results showed that the potential vector, Haplaxius crudus, is more abundant on LB-infected than on healthy palms. -
Diversity and Abundance of Insect Herbivores Foraging on Seedlings in a Rainforest in Guyana
R Ecological Entomology (1999) 24, 245±259 Diversity and abundance of insect herbivores foraging on seedlings in a rainforest in Guyana YVES BASSET CABI Bioscience: Environment, Ascot, U.K. Abstract. 1. Free-living insect herbivores foraging on 10 000 tagged seedlings representing ®ve species of common rainforest trees were surveyed monthly for more than 1 year in an unlogged forest plot of 1 km2 in Guyana. 2. Overall, 9056 insect specimens were collected. Most were sap-sucking insects, which represented at least 244 species belonging to 25 families. Leaf-chewing insects included at least 101 species belonging to 16 families. Herbivore densities were among the lowest densities reported in tropical rainforests to date: 2.4 individuals per square metre of foliage. 3. Insect host speci®city was assessed by calculating Lloyd's index of patchiness from distributional records and considering feeding records in captivity and in situ. Generalists represented 84 and 78% of sap-sucking species and individuals, and 75 and 42% of leaf-chewing species and individuals. In particular, several species of polyphagous xylem-feeding Cicadellinae were strikingly abundant on all hosts. 4. The high incidence of generalist insects suggests that the Janzen±Connell model, explaining rates of attack on seedlings as a density-dependent process resulting from contagion of specialist insects from parent trees, is unlikely to be valid in this study system. 5. Given the rarity of ¯ushing events for the seedlings during the study period, the low insect densities, and the high proportion of generalists, the data also suggest that seedlings may represent a poor resource for free-living insect herbivores in rainforests. -
Psyllid Host-Plants (Hemiptera: Psylloidea): Resolving a Semantic Problem
242 Florida Entomologist 97(1) March 2014 PSYLLID HOST-PLANTS (HEMIPTERA: PSYLLOIDEA): RESOLVING A SEMANTIC PROBLEM 1,* 2 3 2 DANIEL BURCKHARDT , DAVID OUVRARD , DALVA QUEIROZ AND DIANA PERCY 1Naturhistorisches Museum, Augustinergasse 2, CH-4001 Basel, Switzerland 2Department of Life Sciences, Natural History Museum, Cromwell Road, London SW7 5BD, UK 3Embrapa Florestas, Colombo/PR, Brazil *Corresponding author; E-mail: [email protected] ABSTRACT Evolutionary and biological patterns can be obscured by inadequate or ill-defined terminol- ogy. An example is the generally very specific relationship between the sap-feeding hemip- teran group, psyllids, and their breeding plants, commonly called host-plants. The literature is clogged with references to so called ‘hosts’, which are often merely plants on which psyllids were found accidentally, and no immature development was detected. Recently the term host has also been applied by some authors to any plant on which immature or adults feed. Here we propose a terminology to clarify associated plant definitions, and we suggest restricting the use of the term host-plant to plants on which a psyllid species completes its immature to adult life cycle. For the other plant associations we suggest the terms overwintering or shel- ter plant (plants on which adult psyllids overwinter and on which they may feed), food plant (plants on which adult psyllids feed, but do not breed and do not spend an extended period of time) and casual plant (plants on which adult psyllids land but do not feed). Key Words: jumping plant-lice, psyllids, host-plant, terminology RESUMEN Patrones evolutivos y biológicos pueden ser oscurecidas por la terminología inadecuada o mal definida. -

Many natural enemies rely on floral resources to complete their life cycle. Farmers need to ensure the availability of suitable and sufficient floral biodiversity. This review summarizes 66 studies on the management of floral biodiversity in apple orchards, published since 1986. Approaches followed different degrees of intervention: short-term practices (mowing regime and weed maintenance, cover crops), establishment of durable ecological infrastructures (perennial flower strips, hedgerows) and re-design of the crop system (intercropping, agroforestry). Although short-term practices did not always target the nutrition of natural enemies by flowering plants, living conditions for them (alternative prey, provision of habitat) were often improved. Perennial flower strips reliably enhanced natural enemies and techniques for their introduction continuously developed. -
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.
