Download or read book Forest Pest and Disease Management in Latin America written by Sergio A. Estay and published by Springer Nature. This book was released on 2020-02-26 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: By providing multiple economic goods and ecosystem services, Latin American forests play a key role in the environmental, social and economic welfare of the region’s countries. From the tropical forests of Central America to the Mediterranean and temperate vegetation of the southern cone, these forests face a myriad of phytosanitary problems that negatively impact on both conservation efforts and forest industry. This book brings together the perspectives of several Latin American researchers on pest and disease management. Each chapter provides modern views of the status and management alternatives to problems as serious as the impact of introduced exotic insects and diseases on Pinus and Eucalyptus plantations throughout the continent, and the emergence of novel insect outbreaks in tropical and temperate native forests associated with global warming. It is a valuable guide for researchers and practitioners working on forest health in Latin America and around the world.

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 A Revision of the Melanolophiini Lepidoptera Geometridae written by Frederick H. Rindge and published by . This book was released on 1990 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The present work is the first attempt to unite all the genera of the Melanolophiini in one paper, and to give a revision of the tribe. The males can be recognized by the following group of characters: antennae pectinate, with the pectinations arising basally on their segments; abdomens are variously modified, usually having the intersegmental membrane between A3 and A4 ventrolaterally with either an invagination on each side, some with a small projecting setal tuft, or a large, very prominent double setal tuft, plus a prominent comblike paired structure of elongate, apically flattened scales on the intersegmental membrane between A7 and A8 (although this may be reduced to a flattened sclerotized band and a few setae); the inner face of the valves is never simple, having a variably developed sacculus, often in the form of a spinose process or an elongate free arm, and/or a swollen, sclerotized, spinose harpe. The females have the signum reduced or absent; otherwise they have to be associated with their males for tribal placement. The early stages of only a very few species are known; these are characterized in the mature larva by having seta SDX2 in the subdorsal region of the anterior abdominal segments, and with all the crochets of the prolegs being in one group. The Melanolophiini are restricted to the New World, where the species range from southern Alaska to southern South America. A few are known from both the Greater and Lesser Antilles, but the group is not known from Chile. Fifteen genera are recognized; Antiphoides, Arilophia, Minyolophia, Segalenara, and Tesiophora are described as new. All genera are completely described, with the adults and the genitalia of both sexes illustrated; a key to the males is provided. For some genera only brief references are made to the included species, while in others complete generic revisions are presented, with diagnoses of the previously described species and descriptions of new taxa. Included in the latter category are Anavinemina Rindge, Galenara McDunnough, and Vinemina McDunnough, as well as the newly described genera. Fifty-two new species are described. These include Anavinemina acomos, A. brachiata, A. evexa, A. lunaris, A. semicircula, A. striola, A. wellingi, Arilophia rawlinsi, Astalotesia hollandi, Carphoides durango, C. oaxaca, Galenara antilectos, G. bispicula, G. carina, G. engonios, G. ferrugina, G. leberasae, G. phoxe, G. tlaxcala, G. vernonae, Melanolophia anchicaya, M. calimae, M. mima, M. muriensis, M. necopina, M. orthogonia, M. ovata, M. peridoxa, M. plecte, M. pseudoxa, M. sullivani, Pherotesia dystactos, P. garka, P. inhamata, P. obunca, P. pedaria, P. quadra, P. ralla, Minyolophia distincta, M. hadra, M. inermis, M. parilis, M. prolixa, M. yanayacu, Tesiophora aquila, T. cerezal, T. entephros, T. exallos, T. orthe, T. pulla, Vinemina digita, and V. olivaria. These 52 new species bring the number in this tribe to just under 200; almost one-half are placed in Melanolophia. Six new combinations are proposed: Anavinemina rindgei (Beutelspacher), Antiphoides errantaria (McDunnough), A. dentata (Dyar), Minyolophia azenioides (Herbulot), Segalenara phyararia (Dyar), and Tesiophora humidaria (Schaus). There is one new status, as Pherotesia minuisca Rindge is raised to species rank"--Page 3
