This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unmitigated pest risk potential for the importation of Pinus and Abies logs from all states of Mexico into the United States was assessed by estimating the probability and consequences of establishment of representative insects and pathogens of concern. Twenty-two individual pest risk assessments were prepared for Pinus logs, twelve dealing with insects and ten with pathogens. Six individual assessments were prepared for Abies logs. The selected organisms were representative examples of insects and pathogens found on the bark, in the bark, and in the wood of Pinus or Abies logs. Among the insects and pathogens assessed for Mexican pines, eight (Dendroctonus mexicanus, Coptotermes crassus, Pterophylla beltrani, Ips bonanseai, Gnathotrichus perniciosus, Gnathotrichus nitidifrons, Fusarium subglutinans f. sp. pini, and Ophiostoma spp.) were rated a high risk potential. A moderate pest risk potential was assigned to nine other organisms or groups of organisms including Pineus spp., Lophocampa alternata, Hylesia frigida, Hypoderma spp., Lophodermella spp., Synanthedon cardinalis, Heterobasidion annosum, Sphaeropsis sapinea, Bursaphelenchus xylophilus, Cronartium spp., and Peridermium spp. The pests of concern with a moderate or high pest risk potential for Abies logs include Lophocampa alternata, Scolytus mundus, S. aztecus, Pseudohylesinus variegatus, P. magnus, Ophiostoma abietinum, and Heterobasidion annosum. For those organisms of concern that are associated with Mexican Pinus and Abies logs, specific phytosanitary measures may be required to ensure the quarantine safety of proposed importations.

Download or read book Pest Risk Assessment of the Importation Into the United States of Unprocessed Eucalyptus Logs and Chips from South America written by and published by . This book was released on 2001 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this report, we assess the unmitigated pest risk potential of importing Eucalyptus logs and chips from South America into the United States. To do this, we estimated the likelihood and consequences of introducing representative insects and pathogens of concern. Nineteen individual pest risk assessments were prepared, eleven dealing with insects and eight with pathogens. The selected organisms were representative examples of insects and pathogens found on the foliage, on the bark, in the bark, and in the wood of Eucalyptus spp. Among the insects and pathogens assessed, eight were rated a high risk potential: purple moth (Sarsina violescens), scolytid bark and ambrosia beetles (Scolytopsis brasiliensis, Xyleborus retusus, Xyleborus biconicus, Xyleborus spp.), carpenterworm (Chilecomadia valdiviana) on Eucalyptus nitens, round-headed wood borers (Chydarteres striatus, Retrachyderes thoracicus, Trachyderes spp., Steirastoma breve, Stenodontes spinibarbis), eucalyptus longhorned borer (Phoracantha semipunctata), Botryosphaeria cankers (Botryosphaeria dothidea, Botryosphaeria obtusa, Botryosphaeria ribi), Ceratocystis canker (Ceratocystis fimbriata), and pink disease (Erythricium salmonicolor). A moderate pest risk potential was assigned to eleven other organisms or groups of organisms: eucalypt weevils (Gonipterus spp.), carpenterworm (Chilecomadia valdiviana) on two Eucalyptus species other than E. nitens, platypodid ambrosia beetle (Megaplatypus parasulcatus), yellow phorancantha borer (Phoracantha recurva), subterranean termites (Coptotermes spp., Heterotermes spp.), foliar diseases (Aulographina eucalypti, Cryptosporiopsis eucalypti, Cylindrocladium spp., Phaeophleospora spp., Mycosphaerella spp.), eucalyptus rust (Puccinia psidii), Cryphonectria canker (Cryphonectria cubensis), Cytospora cankers (Cytospora eucalypticola, Cytospora eucalyptina), Coniothyrium canker (Coniothyrium zuluense), and root and stem rots (Armillaria spp., Phellinus spp., Ganoderma sp., Gymnopilus spectabilis). For those organisms of concern that are associated with logs and chips of South American Eucalyptus spp., specific phytosanitary measures may be required to ensure the quarantine safety of proposed importations.

Download or read book Phytosanitary Risks Associated with the Global Movement of Forest Products written by Isabel Leal and published by . This book was released on 2010 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: International trade in forest products constitutes an important component of the world's economy. Forest products may have pests associated with them that pose phytosanitary risks and could have the potential to be introduced and become established into importing countries. These risks may result in the implementation of phytosanitary requirements that could affect trade. This report presents current knowledge of the phytosanitary threats and potential risk-reducing measures associated with the global trade in forest commodities. Commodities discussed include: round wood, sawn wood, wood chips (treated and untreated), and plant parts and live propagative materials. As wood undergoes processing, its phytosanitary risks are generally reduced. For instance, greater phytosanitary risks are associated with international movement of round wood with bark. As bark is removed, and sawn wood is produced, the risks decrease significantly through this production process. Untreated and live forest products can present high phytosanitary risks. This review of commodity-based phytosanitary risks associated with the global movement of forest products provides the global phytosanitary community with scientific information regarding major pests associated with forest products and recommends effective approaches to mitigate associated risks.
