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. -

This disease is responsible for the destruction of several Diaphorina citri is often referred to as citrus psylla, but this citrus industries in Asia and Africa (Manjunath 2008). is the same common name sometimes applied to Trioza Until recently, the Asian citrus psyllid did not occur in erytreae (Del Guercio), the psyllid pest of citrus in Africa. North America or Hawaii, but was reported in Brazil, by To avoid confusion, T. erytreae should be referred to as the Costa Lima (1942) and Catling (1970). African citrus psyllid or the two-spotted citrus psyllid (the latter name is in reference to a pair of spots on the base of the abdomen in late stage nymphs). 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 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. -
Specialization in Plant–Pollinator Networks
Villalobos et al. BMC Ecol (2019) 19:34 https://doi.org/10.1186/s12898-019-0250-z BMC Ecology RESEARCH ARTICLE Open Access Specialization in plant–pollinator networks: insights from local-scale interactions in Glenbow Ranch Provincial Park in Alberta, Canada Soraya Villalobos1* , José Manuel Sevenello‑Montagner2 and Jana C. Vamosi1 Abstract Background: The occurrence and frequency of plant–pollinator interactions are acknowledged to be a function of multiple factors, including the spatio‑temporal distribution of species. The study of pollination specialization by exam‑ ining network properties and more recently incorporating predictors of pairwise interactions is emerging as a useful framework, yet integrated datasets combining network structure, habitat disturbance, and phylogenetic information are still scarce. Results: We found that plant–pollinator interactions in a grassland ecosystem in the foothills of the Rocky Mountains are not randomly distributed and that high levels of reciprocal specialization are generated by biological constraints, such as foral symmetry, pollinator size and pollinator sociality, because these traits lead to morphological or pheno‑ logical mismatching between interacting species. We also detected that landscape degradation was associated with diferences in the network topology, but the interaction webs still maintained a consistently higher number of recip‑ rocal specialization cases than expected. Evidence for the reciprocal evolutionary dependence in visitors (e.g., related pollinators visiting related plants) were weak in this study system, however we identifed key species joining clustered units. Conclusions: Our results indicate that the conserved links with keystone species may provide the foundation for generating local reciprocal specialization. From the general topology of the networks, plant–pollinators interactions in sites with disturbance consisted of generalized nodes connecting modules (i.e., hub and numerous connectors). -

Patch Research Associate of Entomology Special Member David A. Mortensen Professor of Weed and Applied Plant Ecology Heather Hines Assistant Professor of Biology and Entomology Gary W. Felton Professor and Department Head of Entomology *Signatures are on file in the Graduate School ii Abstract Angiosperms and insect pollinators, especially bees, share a rich ecological and evolutionary history in which the radiation of the groups occurred through coevolutionary processes. This is because flowers facilitate reproduction through the transfer of pollen by attracting bees to flowers, and providing bees their entire source of nutrition. Historically, it was believed that bees were innately destined to visit flowers that provided specific or attractive morphologies, colors, or scents, known as pollination syndromes. However, individuals within bee species may visit and collect resources from different plant species during the day, season, and across years. Bee nutrition is partitioned between floral nectar which provides energy (carbohydrates) for foraging bees to collect nutritionally complex pollen (protein, lipids, and micronutrients). Because pollen quality differs between plant species and affects the health and development of bee larvae and adults, we expect that bee species forage to collect the right balance of pollen nutrients from their host-plant species. -
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. -
Bee Nutrition and Floral Resource Restoration Vaudo Et Al
Available online at www.sciencedirect.com ScienceDirect Bee nutrition and floral resource restoration Anthony D Vaudo, John F Tooker, Christina M Grozinger and Harland M Patch Bee-population declines are linked to nutritional shortages [1–5,6 ,7 ]. We propose a rational approach for restoring caused by land-use intensification, which reduces diversity and and conserving pollinator habitat that focuses on bee abundance of host-plant species. Bees require nectar and nutrition by firstly, determining the specific nutritional pollen floral resources that provide necessary carbohydrates, requirements of different bee species and how nutrition proteins, lipids, and micronutrients for survival, reproduction, influences foraging behavior and host-plant species and resilience to stress. However, nectar and pollen nutritional choice, and secondly, determining the nutritional quality quality varies widely among host-plant species, which in turn of pollen and nectar of host-plant species. Utilizing this influences how bees forage to obtain their nutritionally information, we can then thirdly, generate targeted plant appropriate diets. Unfortunately, we know little about the communities that are nutritionally optimized for pollina- nutritional requirements of different bee species.

Pollinating Flies (Diptera): a Major Contribution to Plant Diversity and Agricultural Production Axel Ssymank', C.A
Pollinating Flies (Diptera): A major contribution to plant diversity and agricultural production Axel Ssymank', C.A. Kearns2, Thomas Pape 3 andF. Christian Thompson 4 Abstract. Diptera are one of the three largest and most diverse animal groups in the world. As an often neglected but important group of pollinators, they play a significant role in agrobiodiversity and the biodiversity of plants everywhere. Flies are present in almost all habitats and biomes and for many medicinal, food and ornamental plants, pollinating flies guarantee or enhance seed and fruit production. They are important in the natural landscape, in agriculture and in greenhouses, and have recently come into use in the production of seeds for seed banks. The Sao Paulo Pollinator Initiative, the CBD, and Pollinator secretariats were important starting points in the international recognition of pollinator importance. However, large gaps in our knowledge of the role of Diptera in pollination networks need to be addressed in order to sustain agriculture and to enable appropriate responses to climate change. At this 9th Conference of the Parties we would like to draw attention to the role of often-neglected Dipteran pollinators, to stress their current importance and potential future, use as pollinators in agriculture. A case study on flower flies that act as important pollinators, as adults, and major biocontrol agents, as larvae, illustrates their double importance for agriculture. Keywords. Diptera, Agrobiodiversity, Pollination, Flower Flies, Bio-Control, medicinal plants, ornamental plants AUTHORS' ADDRESSES: 2004) were presented.
