  • Remote Sensing and Geographical Information Analytical Techniques for Modelling Ommatissus Lybicus (Hemiptera: Tropiduchidae) Habitat and Population Densities
    Remote Sensing and Geographical Information Analytical Techniques for Modelling Ommatissus lybicus (Hemiptera: Tropiduchidae) Habitat and Population Densities Khalifa M Al-Kindi 1 , Paul Kwan Corresp., 1 , Nigel Andrew 2 , Mitchell Welch 1 1 School of Science and Technology, University of New England, Armidale, NSW, Australia 2 Centre for Behavioural and Physiological Ecology, University of New England, Armidale, NSW, Australia Corresponding Author: Paul Kwan Email address: [email protected] In order to understand the distribution and prevalence of Ommatissus lybicus (Homoptera: Tropiduchidae) as well as analyse their current biographical patterns and predict their future spread, comprehensive and highly sophisticated information on the environmental, climatic, and agricultural practices are essential. The analytical techniques available in modern spatial analysis packages, such as Remote Sensing and Geographical Information Systems, can help detect and model spatial links and correlations between the presence, absence and density of O. lybicus in response to climatic, environmental and human factors. The main objective of this paper is to review remote sensing and geographical information analytical techniques that can be applied in mapping and modelling the habitat and population density of O. lybicus in Oman. An exhaustive search of related literature revealed that there are few studies linking location-based infestation levels of pests like the O. lybicus with climatic, environmental and human practice related variables in the Middle East. Our review also highlights the accumulated knowledge and addresses the gaps in this area of research. Furthermore, it makes recommendations for future studies, and gives suggestions on monitoring and surveillance sites that are necessary in designing both local and regional level integrated pest management (IPM) policing of palm tree and other affected cultivated crops.

  • The Planthopper Genus Trypetimorpha: Systematics and Phylogenetic Relationships (Hemiptera: Fulgoromorpha: Tropiduchidae)
    JOURNAL OF NATURAL HISTORY, 1993, 27, 609-629 The planthopper genus Trypetimorpha: systematics and phylogenetic relationships (Hemiptera: Fulgoromorpha: Tropiduchidae) J. HUANG and T. BOURGOINt* Pomological Institute of Shijiazhuang, Agricultural and Forestry Academy of Sciences of Hebei, 5-7 Street, 050061, Shijiazhuang, China t Mus#um National d'Histoire Naturelle, Laboratoire d'Entomologie, 45 rue Buffon, F-75005, Paris, France (Accepted 28 January 1993) The genus Trypetimorpha is revised with the eight currently recognized species described or re-described. Four new species are described and seven new synonymies are proposed. Within Trypetimorphini sensu Fennah (1982), evidences for the monophyly of each genus are selected, but Caffrommatissus is transferred to the Cixiopsini. Monophyly of Trypetimorphini, restricted to Trypetimorpha and Ommatissus, is discussed. A key is given for the following Trypetimorpha species: (1) T. fenestrata Costa ( = T. pilosa Horvfith, syn. n.); (2) T. biermani Dammerman (= T. biermani Muir, syn. n.; = T. china (Wu), syn. n.; = T. formosana Ishihara, syn. n.); (3) T. japonica Ishihara ( = T. koreana Kwon and Lee, syn. n.); (4) T. canopus Linnavuori; (5) T. occidentalis, sp. n. (= T. fenestrata Costa, sensu Horvfith); (6) T. aschei, sp. n., from New Guinea; (7) T. wilsoni, sp. n., from Australia; (8) T. sizhengi, sp. n., from China and Viet Nam. Study of the type specimens of T. fenestrata Costa shows that they are different from T. fenestrata sensu Horvfith as usually accepted, which one is redescribed here as T. occidentalis.

  • Insect Egg Size and Shape Evolve with Ecology but Not Developmental Rate Samuel H
    ARTICLE https://doi.org/10.1038/s41586-019-1302-4 Insect egg size and shape evolve with ecology but not developmental rate Samuel H. Church1,4*, Seth Donoughe1,3,4, Bruno A. S. de Medeiros1 & Cassandra G. Extavour1,2* Over the course of evolution, organism size has diversified markedly. Changes in size are thought to have occurred because of developmental, morphological and/or ecological pressures. To perform phylogenetic tests of the potential effects of these pressures, here we generated a dataset of more than ten thousand descriptions of insect eggs, and combined these with genetic and life-history datasets. We show that, across eight orders of magnitude of variation in egg volume, the relationship between size and shape itself evolves, such that previously predicted global patterns of scaling do not adequately explain the diversity in egg shapes. We show that egg size is not correlated with developmental rate and that, for many insects, egg size is not correlated with adult body size. Instead, we find that the evolution of parasitoidism and aquatic oviposition help to explain the diversification in the size and shape of insect eggs. Our study suggests that where eggs are laid, rather than universal allometric constants, underlies the evolution of insect egg size and shape. Size is a fundamental factor in many biological processes. The size of an 526 families and every currently described extant hexapod order24 organism may affect interactions both with other organisms and with (Fig. 1a and Supplementary Fig. 1). We combined this dataset with the environment1,2, it scales with features of morphology and physi- backbone hexapod phylogenies25,26 that we enriched to include taxa ology3, and larger animals often have higher fitness4.

Species level identifications in this group generally are possible only by examination of male specimens; prior DNA barcode analyses of a limited range of Auchenorrhyncha indicate that this approach may provide an expedient means to identify species within this diverse group. In this study we explored the utility of DNA barcoding for identification of a wider range of Auchenorrhyncha species than has been examined previously. Diverse fulgoroid (planthopper) and membracoid (leafhopper and allies) Auchenorrhyncha were sampled from Barrow Island, Western Australia, and identified to the least inclusive taxonomic units using morphology. DNA barcodes from 546 adult specimens were obtained and analysed using a General mixed Yule – Coalescent (GMYC) modelling approach to genetically delimit putative species, as a comparison to the morphospecies identifications.

Here, we describe a bizarre armoured planthopper nymph: Spinonympha shcherbakovi gen. et sp. nov. from mid-Cretaceous Kachin amber. The new genus and species is characterized by its large size, armoured body, extremely long rostrum, and leg structure. The fossil nymph cannot be attributed to any known planthopper family, but can be excluded from many families due to its large size and leg structure. The armoured body was probably developed for defence, and the extremely long rostrum indicates that, in the past, planthopper feeding on trees with thick and rough bark was more widespread than today. The new find reveals a new armoured morphotype previously unknown in planthopper nymphs. Abstract: The fossil record of adult planthoppers is comparatively rich, but nymphs are rare and not well studied.

  • 2016 Summit Program
    General Information General Welcome Dear colleagues, Welcome to the 6th annual iDigBio-hosted summit for ADBC scientists and students! Again this year the summit is a large event with an anticipated 110 participants, including those from 18 TCNs AND PENs, other colleagues working with biodiversity collections data, guests from the NSF, and iDigBio. As in past years, we have a packed agenda of presentations and breakout groups, but we also have plenty of opportunities for networking and discussion. The latter include daily morning and afternoon breaks, lunches, an evening reception at the Tennessee Aquarium, a free evening to organize your own discussion group, and an open meeting space that is available any time of day for small groups to gather and discuss topics of specific interest to them. The national effort to digitize information in biocollections has been successfully catalyzed by funding from NSF and activities of TCNs and iDigBio. As a community, we have defined digitization priorities, integrated best practices into workflows, provided cyberinfrastructure resources including a search portal, addressed major challenges via working groups, and built collaborations with data providers/users. We have improved digitization practices, increased involvement in digitization and training, and adopted informatics tools that improve the efficiency and scalability of digitization in all types of collections. In its 6th year, iDigBio is working with staff in more than 500 collections in 275 institutions. We have communicated with our stakeholders to increase access to collections data through workshops, webinars, the iDigBio Spotlight, and social media. During its first 5 years, iDigBio sponsored attendance of 3,083 participants from 484 institutions to 82 workshops that targeted digitization-related topics.

Mahmoudi1&*, A. Sahragard1, H. Pezhman2 and M. Ghadamyari1 1. Department of Plant Protection, Faculty of Agricultural Sciences, University of Guilan, Rasht, Iran, 2. Agricultural Research Center of Fars, Shiraz, Iran. *Corresponding author, E-mail: [email protected] Abstract In this study, mineral oil and kaolin as alternatives to conventional pesticide (diazinon) were evaluated to manage Dubas bug, Ommatissus lybicus de Bergevin, in the field and laboratory. In the field experiment, effect of four treatments was evaluated against population density (first and second nymphal stages) and honeydew production (as main damage) of Dubas bug. A single application of each product was applied at the recommended rates. Results showed that kaolin, mineral oil and diazinon were statistically similar in decreasing the population density and damage of Dubas bug. This result makes kaolin and mineral oil as potential alternatives to conventional insecticides in date palm orchards. In the laboratory, mineral oil was effective on egg mortality. In settling choice test, the ability of Dubas bug to discriminate between kaolin-treated and kaolin- untreated leaflets increased significantly over the time and females laid more eggs on untreated leaflets than kaolin-treated leaflets. Results of no-choice test revealed
