The present geological period has more species than any other, yet the current rate of extinction of species is greater now than at any time in the past. Ecosystems and communities are being degraded and destroyed, and species are being driven to extinction. The species that persist are losing genetic variation as the number of individuals in populations shrinks, unique populations and subspecies are destroyed, and remaining populations become increasingly isolated from one another. The cause of this loss of biological diversity at all levels is the range of human activity that alters and destroys natural habitats to suit human needs.” (Primack, 2002). CapeNature launched its State of Biodiversity Programme (SoBP) to assess and monitor the state of biodiversity in the Western Cape in 1999. This programme delivered its first report in 2002 and these reports are updated every five years. The current report (2007) reports on the changes to the state of vertebrate biodiversity and land under conservation usage.

Nineteen species as well as the subfamily Epitraninae and the genera Bucekia Steffan, Epitranus Walker, Proconura Dodd, and Tanycoryphus Cameron, are newly recorded from Egypt. A single species previously placed in the genus Hockeria is transferred to Euchalcis Dufour as E. rufula (Nikol’skaya, 1960) comb. nov.

Whilst recent studies have reported the presence of Epitraninae in countries of the Middle East, there are no published records from the European continent. A female specimen belonging to the Epitranus hamoni species complex was collected in Salamis island, Attica, Greece, and deposited at the Museum of Zoology (Athens).

    Eucalyptus 2018 17-21 September 2018, Le Corum, Montpellier - France Eucalyptus 2018 Managing Eucalyptus plantations under global changes Abstracts Book Foreword Eucalyptus trees cover about 20 million hectares in more than 90 countries around the world with major centers in Brazil (5.7 m ha), India (3.9 m ha) and China (4.5 m ha). Eucalypts are widely grown in commercial plantations to produce raw material for the industry (pulp and paper, charcoal, sawn timber, wood panels) but also in small woodlots for the production of firewood and charcoal for domestic uses. The considerable expansion of these plantations in recent decades reflects major competitive advantages of eucalypts relative to other tree species in terms of productivity, tolerance to biotic and abiotic stresses, wood quality for a wide variety of uses and ability to be managed in coppice. However, the requirements in water and nutrients of eucalypt trees are high to reach high biomass productions and the environmental impact of the silviculture is still a matter of debate. In a context of global changes with more frequent drought events, temperature rise and rapid expansion of pests and diseases, the sustainability of eucalypt plantations is of concern in many regions. Interdisciplinary research is urgently needed to improve the adaptation of eucalypt plantations to global changes. Cirad and I-Site MUSE organize an international conference under the auspices of IUFRO (Division 2.08.03 Improvement and culture of eucalypts and Division 1.02.01 Ecology and silviculture of plantation forests in the tropics) to present recent advances likely to improve the management of eucalypt plantations in tropical, sub-tropical and Mediterranean regions.

    Importation of Fresh Beans (Phaseolus vulgaris L.), Shelled or in Pods, from Jordan into the Continental United States A Qualitative, Pathway-Initiated Risk Assessment February 14, 2011 Version 2 Agency Contact: Plant Epidemiology and Risk Analysis Laboratory Center for Plant Health Science and Technology United States Department of Agriculture Animal and Plant Health Inspection Service Plant Protection and Quarantine 1730 Varsity Drive, Suite 300 Raleigh, NC 27606 Pest Risk Assessment for Beans from Jordan Executive Summary In this risk assessment we examined the risks associated with the importation of fresh beans (Phaseolus vulgaris L.), in pods (French, green, snap, and string beans) or shelled, from the Kingdom of Jordan into the continental United States. We developed a list of pests associated with beans (in any country) that occur in Jordan on any host based on scientific literature, previous commodity risk assessments, records of intercepted pests at ports-of-entry, and information from experts on bean production. This is a qualitative risk assessment, as we express estimates of risk in descriptive terms (High, Medium, and Low) rather than numerically in probabilities or frequencies. We identified seven quarantine pests likely to follow the pathway of introduction. We estimated Consequences of Introduction by assessing five elements that reflect the biology and ecology of the pests: climate-host interaction, host range, dispersal potential, economic impact, and environmental impact. We estimated Likelihood of Introduction values by considering both the quantity of the commodity imported annually and the potential for pest introduction and establishment. We summed the Consequences of Introduction and Likelihood of Introduction values to estimate overall Pest Risk Potentials, which describe risk in the absence of mitigation.

    LATE SUMMER EDITION: JANUARY / AFRICAN FEBRUARY 2018 - 1 BUTTERFLY THE LEPIDOPTERISTS’ SOCIETY OF AFRICA NEWS LATEST NEWS Welcome to the first newsletter of 2018! I trust you all have returned safely from your December break (assuming you had one!) and are getting into the swing of 2018? With few exceptions, 2017 was a very poor year butterfly-wise, at least in South Africa. The drought continues to have a very negative impact on our hobby, but here’s hoping that 2018 will be better! Braving the Great Karoo and Noorsveld (Mark Williams) In the first week of November 2017 Jeremy Dobson and I headed off south from Egoli, at the crack of dawn, for the ‘Harde Karoo’. (Is there a ‘Soft Karoo’?) We had a very flexible plan for the six-day trip, not even having booked any overnight accommodation. We figured that finding a place to commune with Uncle Morpheus every night would not be a problem because all the kids were at school. As it turned out we did not have to spend a night trying to kip in the Pajero – my snoring would have driven Jeremy nuts ... Friday 3 November The main purpose of the trip was to survey two quadrants for the Karoo BioGaps Project. One of these was on the farm Lushof, 10 km west of Loxton, and the other was Taaiboschkloof, about 50 km south-east of Loxton. The 1 000 km drive, via Kimberley, to Loxton was accompanied by hot and windy weather. The temperature hit 38 degrees and was 33 when the sun hit the horizon at 6 pm.

  • Invasion History and Management of Eucalyptus Snout Beetles in the Gonipterus Scutellatus Species Complex
    Journal of Pest Science https://doi.org/10.1007/s10340-019-01156-y REVIEW Invasion history and management of Eucalyptus snout beetles in the Gonipterus scutellatus species complex Michelle L. Schröder1 · Bernard Slippers2 · Michael J. Wingfeld2 · Brett P. Hurley1 Received: 8 December 2018 / Revised: 15 July 2019 / Accepted: 17 August 2019 © Springer-Verlag GmbH Germany, part of Springer Nature 2019 Abstract Gonipterus scutellatus (Coleoptera: Curculionidae), once thought to be a single species, is now known to reside in a com- plex of at least eight cryptic species. Two of these species (G. platensis and G. pulverulentus) and an undescribed species (Gonipterus sp. n. 2) are invasive pests on fve continents. A single population of Anaphes nitens, an egg parasitoid, has been used to control all three species of Gonipterus throughout the invaded range. Limited knowledge regarding the diferent cryptic species and their diversity signifcantly impedes eforts to manage the pest complex outside the native range. In this review, we consider the invasion and taxonomic history of the G. scutellatus cryptic species complex and the implications that the cryptic species diversity could have on management strategies. The ecological and biological aspects of these pests that require further research are identifed. Strategies that could be used to develop an ecological approach towards managing the G. scutellatus species complex are also suggested. Keywords Gonipterus scutellatus · Cryptic species · Invasion history · Biological control · Anaphes nitens · Eucalyptus snout beetle Key message Introduction Eucalyptus spp. and their relatives have been extensively • The Eucalyptus snout beetle (ESB) continues to spread planted outside their native range for more than a century and impact Eucalyptus production worldwide.
