Pest Categorisation of Popillia Japonica SCIENTIFIC OPINION ADOPTED: 27 September 2018 doi: 10.2903/j.efsa.2018.5438 Pest categorisation of Popillia japonica EFSA Panel on Plant Health (PLH), Claude Bragard, Katharina Dehnen-Schmutz, Francesco Di Serio, Paolo Gonthier, Marie-Agnes Jacques, Josep Anton Jaques Miret, Annemarie Fejer Justesen, Christer Sven Magnusson, Panagiotis Milonas, Juan A Navas-Cortes, Stephen Parnell, Roel Potting, Philippe Lucien Reignault, Hans-Hermann Thulke, Wopke Van der Werf, Antonio Vicent Civera, Jonathan Yuen, Lucia Zappala, Ewelina Czwienczek and Alan MacLeod Abstract The Panel on Plant Health performed a pest categorisation of Popillia japonica (Coleoptera: Scarabaeidae) for the EU. P. japonica is a distinguishable species listed in Annex IAII of Council Directive 2000/29/EC. It is native to Japan but established in the USA in the early 20th century. It spreads from New Jersey to most US states east of the Mississippi, some to the west and north into Canada. P. japonica feeds on over 700 plant species. Adults attack foliage and fruit surfaces. They can cause serious injury to tree fruits and soft fruit, vegetable crops, ornamental herbaceous plants, shrubs, vines and trees. Larvae are root feeders regarded as serious pests of lawns and turf, vegetables and nursery stock. Adults emerge during the summer and can fly short distances on warm sunny days. The life cycle is usually completed in one year. In cooler regions, development takes two years. P. japonica occurs in the EU in the Azores (Portugal), Lombardy and Piedmont (Italy) where it is under official control. Adults are suspected of being able to spread on aircraft as hitchhikers, i.e. without host plants. Soil accompanying plants for planting provides a pathway for further introductions. Hosts are widely available within the EU. Climatic conditions across central and parts of southern EU are suitable for development in one year. Across parts of northern Europe development over two years is likely. Without control, impacts could be expected on a range of plants. Phytosanitary measures are available to reduce the likelihood of introduction of P. japonica. All criteria assessed by EFSA for consideration as a potential Union quarantine pest are met. Plants for planting are not necessarily the main means of spread so P. japonica does not satisfy all criteria necessary for it to be regarded as a Union regulated non-quarantine pest (RNQP). © 2018 European Food Safety Authority.

  • The Beetles Story
    NATURE The Beetles story They outshine butterflies and moths in the world of insects and are a delight for their sheer variety—from the brilliantly coloured to the abysmally dull. But they have their uses, too, such as in museums, where flesh-eating beetles are used to clean off skeletons. Text & photographs by GEETHA IYER THE GIRAFFE WEEVIL (Cycnotrachelus flavotuberosus). Weevils are a type of beetle and they are a menace to crops. 67 FRONTLINE . MARCH 31, 2017 HOW was this watery planet we so much love born? Was it created by God or born off the Big Bang? While arguments swing between science and religion, several ancient cultures had different and interesting per- spectives on how the earth came to be. Their ideas about this planet stemmed from their observations of nature. People living in close prox- imity to nature develop a certain sen- sitivity towards living creatures. They have to protect themselves from many of these creatures and at the same time conserve the very envi- ronment that nurtures them. So there is constant observation and in- teraction with nature’s denizens, es- pecially insects, the most proliferate among all animal groups that stalk every step of their lives. The logic for creation thus revolves around differ- ent types of insects, especially the most abundant amongst them: bee- WATER BEETLE.

  • Developing Biodiverse Green Roofs for Japan: Arthropod and Colonizer Plant Diversity on Harappa and Biotope Roofs
    20182018 Green RoofsUrban and Naturalist Urban Biodiversity SpecialSpecial Issue No. Issue 1:16–38 No. 1 A. Nagase, Y. Yamada, T. Aoki, and M. Nomura URBAN NATURALIST Developing Biodiverse Green Roofs for Japan: Arthropod and Colonizer Plant Diversity on Harappa and Biotope Roofs Ayako Nagase1,*, Yoriyuki Yamada2, Tadataka Aoki2, and Masashi Nomura3 Abstract - Urban biodiversity is an important ecological goal that drives green-roof in- stallation. We studied 2 kinds of green roofs designed to optimize biodiversity benefits: the Harappa (extensive) roof and the Biotope (intensive) roof. The Harappa roof mimics vacant-lot vegetation. It is relatively inexpensive, is made from recycled materials, and features community participation in the processes of design, construction, and mainte- nance. The Biotope roof includes mainly native and host plant species for arthropods, as well as water features and stones to create a wide range of habitats. This study is the first to showcase the Harappa roof and to compare biodiversity on Harappa and Biotope roofs. Arthropod species richness was significantly greater on the Biotope roof. The Harappa roof had dynamic seasonal changes in vegetation and mainly provided habitats for grassland fauna. In contrast, the Biotope roof provided stable habitats for various arthropods. Herein, we outline a set of testable hypotheses for future comparison of these different types of green roofs aimed at supporting urban biodiversity. Introduction Rapid urban growth and associated anthropogenic environmental change have been identified as major threats to biodiversity at a global scale (Grimm et al. 2008, Güneralp and Seto 2013). Green roofs can partially compensate for the loss of green areas by replacing impervious rooftop surfaces and thus, contribute to urban biodiversity (Brenneisen 2006).

  • Phylogeography Reveals an Ancient Cryptic Radiation in East-Asian Tree
    Dufresnes et al. BMC Evolutionary Biology (2016) 16:253 DOI 10.1186/s12862-016-0814-x RESEARCH ARTICLE Open Access Phylogeography reveals an ancient cryptic radiation in East-Asian tree frogs (Hyla japonica group) and complex relationships between continental and island lineages Christophe Dufresnes1, Spartak N. Litvinchuk2, Amaël Borzée3,4, Yikweon Jang4, Jia-Tang Li5, Ikuo Miura6, Nicolas Perrin1 and Matthias Stöck7,8* Abstract Background: In contrast to the Western Palearctic and Nearctic biogeographic regions, the phylogeography of Eastern-Palearctic terrestrial vertebrates has received relatively little attention. In East Asia, tectonic events, along with Pleistocene climatic conditions, likely affected species distribution and diversity, especially through their impact on sea levels and the consequent opening and closing of land-bridges between Eurasia and the Japanese Archipelago. To better understand these effects, we sequenced mitochondrial and nuclear markers to determine phylogeographic patterns in East-Asian tree frogs, with a particular focus on the widespread H. japonica. Results: We document several cryptic lineages within the currently recognized H. japonica populations, including two main clades of Late Miocene divergence (~5 Mya). One occurs on the northeastern Japanese Archipelago (Honshu and Hokkaido) and the Russian Far-East islands (Kunashir and Sakhalin), and the second one inhabits the remaining range, comprising southwestern Japan, the Korean Peninsula, Transiberian China, Russia and Mongolia. Each clade further features strong allopatric Plio-Pleistocene subdivisions (~2-3 Mya), especially among continental and southwestern Japanese tree frog populations. Combined with paleo-climate-based distribution models, the molecular data allowed the identification of Pleistocene glacial refugia and continental routes of postglacial recolonization. Phylogenetic reconstructions further supported genetic homogeneity between the Korean H.

Abdullahi Maikai Murna1 and Ibrahim Salihu Koko2 1Crop Protection Department, College of Agriculture Zuru, Kebbi State, Nigeria. 2Natural Resources Institute,University of Greenwich, Medway Campus, Chatham Maritme, Central Avenue, Chatham, ME4 4TB, UK. Abstract: The effect of time, scouting and calendar application of neem kernel extract (nke) as a bio pesticide and commercial chemical insecticide (30g/l Cypermethrin + 250g/l Dimethoate) on the abundance of predatory insects was investigated using a farmer participatory research in Zuru local government area of Kebbi state of Nigeria.Volunteer farmers planted their favourite cowpea variety IT89KD-245-1 and the insecticides sprays carried out both on weekly (calendar) and scouting based using action threshold of 60% flower infestation/damage commenced at 50% flowering. The result showed that Dipteran predators constituted the majority of the beneficial insects caught, and were mostly Asiliidae and Syrphidae spp. predators’ occurrence was mainly at the late flowering stage. Highly significant difference was found in the number of the beneficial insect between treatments. The species distribution difference between the treatments was also highly significant. Predators were less affected by neem sprays than by chemical insecticide, especially when spray frequency was decreased by scouting. Thus, neem spray as a bio pesticide applied on scouting basis is safe to the beneficial insects therefore, compatible with Integrated Pest Management (IPM).

  • Landfill Contamination Problems: a General Perspective and Engineering Geology Aspects
    Giornale di Geologia Applicata 1 (2005) 203 –211, doi: 10.1474/GGA.2005-01.0-20.0020 Landfill contamination problems: a general perspective and engineering geology aspects A. Tazioli & G. S. Tazioli Department of "Fisica e Ingegneria dei Materiali e del Territorio" Technical University of the Marches, Ancona, via Brecce Bianche. Italy ABSTRACT. Using isotopic methods for the investigation of leachate contamination has produced good results mainly for the control of the interference between landfill activity processes and the underground groundwater environment. In this paper the results of study performed in several italian landfill sites are presented. The results obtained from the investigated areas show that the knowledge of background values of the environment is basic for pollution purpose. In particular, Oxigen-18, Deuterium and Tritium values have allowed groundwater residence times and location of recharge areas to be identified. After that, the use of tritium as pollution tracer provides information on the presence of leachate contamination earlier and better than chemical changes of the standard pollution parameters. Deuterium and Oxygen-18 values of leachate always appear to be somewhat different with respect to the groundwater values, but they can be used as contamination index only in cases of high fractions of leachate. Key terms: Landfill, Monitoring, Tritium, Environmental isotopes, Leachate, Groundwater, Pollution, Rainwater, Waste, Recharge, Leakage, Aquifer, Chemistry. Introduction The qualitative and quantitative characteristics of the fluxes of leachate and biogas are related to the solid waste and to Groundwater and surface water contamination by sanitary the processes taking place in the landfill. An impact on the landfills has been monitored since 1989 in Italy by using underground environment is generally caused by exit- isotope techniques combined with chemical analyses.
