Corythucha Arcuata
Rapid Pest Risk Analysis (PRA) for: Corythucha arcuata November 2018 Summary and conclusions of the rapid PRA This rapid PRA is an update of one produced in 2007 and shows that the oak lace bug has the potential to add strain to trees and ecosystems which are already under threat from other pests and environmental factors. This pest has been present in Europe for some time, but in recent years its distribution has either expanded, or its population levels have increased so there is greater evidence of the potential effects of this pest, though still many uncertainties. The ratings for establishment potential and economic impact remain unchanged, however, more evidence of the potential of this pest to move on wood and wood products has led to a raising of the risk of entry, and evidence from Europe suggests that this pest may have a greater potential environmental impact than previously rated. Risk of entry Although oak trees are the preferred host, there are a number of other tree species that can be potential hosts, and therefore entry has been assessed accordingly. Entry on plants for planting has been assessed as moderately likely with medium confidence. The oak lace bug is most likely to be associated with plants for planting when overwintering under loose bark scales and in crevices. Most plants imported into the UK are likely to be young trees, with few bark crevices. Larger trees do represent a significant 1 risk, as it would be difficult to determine if they were pest free, however the numbers are likely to be fewer. -

The ecological and economic significance of oak stands and the vulnerability of plants to various abiotic and/or biotic factors requires in-depth knowledge of plant-pest interaction. The present study examined the influence of C. arcuata feeding on the photosynthetic characteristics and gas-exchange parameters, mineral nutrient concentrations and defense mechanisms (the activities of some antioxidant enzymes) of leaves of pedunculate oak. The rate of photosynthesis, transpiration and stomatal conductance were lowered by 58.84, 21.66 and 35.71%, respectively, in comparison to non- infested plants. The concentrations of photosynthetic pigments and activities of antioxidant enzymes, catalase and ascorbate peroxidase, were affected by the presence of C. arcuata. To our knowledge this is the first paper providing a report on the physiological responses of Q. robur plants exposed to C. arcuata infestation. Understanding the impact of pests, such as the invasive species C. -

Arctostaphylos mewukka Indian Manzanita, an example of endemism California Floristic Province Ecological Hotspot Criteria: • Over 1500 species of irreplaceable endemic vascular plants CA has over 2100 • Less than 30% of original vegetation CA has 24% • 35 hotspots in the world • Cover just 2.3% of Earth’s land surface • Support more than 50% of plant species • California is one of just 5 Mediterranean hotspots Geology and topography help determine what grows where: Soils from ocean sediment, uplift, glaciation, volcanoes… Plants evolved on varied substrates They’re evolving while we speak! Plants in nature don’t use fertilizer Organic matter: leaves, stems, animal manure, dead things… Soil biota: decomposers (fungi, bacteria) and ‘soil animals’ (protozoa, nematodes) Decomposition by microbes is extremely complex. They decompose and build new organic Nutrient exchanges compounds. Soil interacts with the compounds. Native plants drive ecosystems via evolutionary interdependencies Each member provides ecosystem services There are multiple nutrition strategies Plants tend to congregate in overlapping Plant Communities Examples: • Oak Woodland • Chaparral • Dry Perennial/Scrub • Grassland • Riparian * These are just the main plant communities around Placerville and Cameron Park Oak Woodland Community 5 main oak species (Blue, Valley, Interior, Canyon, and Black oak) Grey pine Toyon Mexican elderberry California bay California -

Whether it is damage of the North American cypress aphid in South America and Africa, or the destruction of maple trees in North America by the Asian long horned beetle, invasive forest pests are a major problem in many parts of the world. Several studies explored microbial control opportunities of invasive forest pests with entomopathogenic bacteria, fungi, and viruses, and some are successfully utilized as a part of integrated forest pest management programs around the world. This manuscript discusses some invasive pests and the status of their microbial control around the world with entomopathogenic fungi. Keywords: microbial control; entomopathogenic fungi; invasive pests; forest insects 1. Introduction Globalization of trade and travel directly or indirectly contributed to the spread of several insects to new areas where they have become serious pests. -
Impacts of Native and Non-Native Plants on Urban Insect Communities: Are Native Plants Better Than Non-Natives?
Impacts of Native and Non-native plants on Urban Insect Communities: Are Native Plants Better than Non-natives? by Carl Scott Clem A thesis submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Master of Science Auburn, Alabama December 12, 2015 Key Words: native plants, non-native plants, caterpillars, natural enemies, associational interactions, congeneric plants Copyright 2015 by Carl Scott Clem Approved by David Held, Chair, Associate Professor: Department of Entomology and Plant Pathology Charles Ray, Research Fellow: Department of Entomology and Plant Pathology Debbie Folkerts, Assistant Professor: Department of Biological Sciences Robert Boyd, Professor: Department of Biological Sciences Abstract With continued suburban expansion in the southeastern United States, it is increasingly important to understand urbanization and its impacts on sustainability and natural ecosystems. Expansion of suburbia is often coupled with replacement of native plants by alien ornamental plants such as crepe myrtle, Bradford pear, and Japanese maple. Two projects were conducted for this thesis. The purpose of the first project (Chapter 2) was to conduct an analysis of existing larval Lepidoptera and Symphyta hostplant records in the southeastern United States, comparing their species richness on common native and alien woody plants. We found that, in most cases, native plants support more species of eruciform larvae compared to aliens. Alien congener plant species (those in the same genus as native species) supported more species of larvae than alien, non-congeners. Most of the larvae that feed on alien plants are generalist species. However, most of the specialist species feeding on alien plants use congeners of native plants, providing evidence of a spillover, or false spillover, effect. -

Konstatēts, ka gan virsējo nobiru slāņa mitrums, kas norāda uz aizdegšanās iespēju, gan daļēji sadalījušos nobiru slāņa mitrums, kas raksturo potenciālo degšanas intensitāti, visciešāk korelē ar Kanādas uguns laika apstākļu indeksu (FWI), tādēļ to rekomendējams izmantot ugunsbīstamības raksturošanai. Prognozes liecina, ka klimata izmaiņu ietekmē pieaugs gan vidējais dienu skaits sezonā ar sevišķi augstu ugunsbīstamību (FWI>17), gan gadu skaits, kad šādas vērtības tiks sasniegtas. Pētījumā prognozētas ne tikai abiotisko, bet arī biotisko faktoru ietekmes izmaiņas klimata izmaiņu rezultātā. Tā, analizējot 25 agresīvāko dendrofāgo kukaiņu sugu savairošanās vēstures teritorijās, kuru klimats līdzīgs Latvijā nākotnē prognozētajam (Centrāleiropā), un uz vēsturisko novērojumu pamata, kas veikti pastāvīgos un īslaicīgos
