Inventario De Plagas Y Enfermedades En Viveros Forestales En Costa Rica
Revista Forestal Mesoamericana Kurú (Enero-Junio, 2021) 18 (42): 17-29 DOI: 10.18845/rfmk.v16i42.5543 Inventario de plagas y enfermedades en viveros forestales en Costa Rica Review of pests and diseases in forest nurseries in Costa Rica Marcela Arguedas Gamboa1 • María Rodríguez-Solís1 • Jaume Cots Ibiza2 • Adrián Martínez Araya3 Recibido: 24/4/2020 Aceptado: 6/8/2020 Publicado: 17/12/2020 Abstract Forest nurseries are the sites of intensive plant production for reforestation and arboriculture programs, which must be of high quality and free from pests and diseases. A sanitary evaluation was carried out in seven forest nurseries in Costa Rica, to prepare the diagnosis of phytosanitary problems. 15 species of insects were diagnosed, 44 of pathogens and 5 of mites, in a total of 80 forest species under production. At the apex, the most important damages are caused by the borer Hypsipila grandella and the cutter Trigona sp. and as pathogens Botrytis sp., Cylindrocladium sp. and Phomopsis sp.; in the foliage, by the insects Eulepte concordalis, Dictyla monotropidia and Austropuccinia psidii, Colletotrichum spp., Dothistroma septosporum, Melampsoridium alni, Oidium sp., Olivea tectonae, and Phyllachora balansae as pathogens. These problems are described and the principles and practices contemplated in Integrated Pest Management (IPM) are recommended for their control. Key words: Seedlings, pathogens, insects, mites, phytosanitary diagnosis. 1.

Analysis on Trade Trend of CITES Regualted Tree Species and Its Impact on Chinese Smes
Analysis on Trade Trend of CITES Regualted Tree Species and its Impact on Chinese SMEs 2017.6 1 2 Preface The Convention on International Trade in Endangered Species of Wild Fauna and Flora (hereinafter referred to as CITES) is signed in Washington D.C. on 3 March 1973, also known as the Washington Convention. It entered into force on 1 July 1975. As an international convention on the control of international trade and the protection of wild flora and fauna, it aims to fully control the import and export of wild animals and plants as well as products thereof and manufactured goods through the regulation system, to promote protection and rational utilization of wild animals and plants resources to ensure that international trade in specimens of wild animals and plants does not threaten their survival. As of December 2016, CITES has 183 member countries where CITES legal framework and trade procedures are applied to regulate and monitor the international trade of species listed in CITES appendices. CITES has been in force for more than 40 years. It has been attracting more and more countries to jointly protect endangered wild animals and plants. At the same time, more and more fauna and flora species have been included in CITES appendices. Up to now, about 5,600 species of animals and 30,000 species of plants are protected by CITES against over-exploitation through international trade. In recent years, the sharp decline of endangered tree species has aroused widespread concern around the world, and over-exploitation is one of the main factors leading to this situation. -

Phytochemical Diversity of Insect Defenses in Tropical and Temperate Plant Families
Cambridge University Press 0521792754 - Advances in Insect Chemical Ecology - Edited by Ring T. Carde and Jocelyn G. Millar Excerpt More information 1 Phytochemical diversity of insect defenses in tropical and temperate plant families John T. Arnason, Gabriel Guillet and Tony Durst Faculty of Science, University of Ottawa, Canada Phytochemical diversity and redundancy One of the most intriguing features of the chemical ecology of plant–insect interac- tions is the remarkable number of different phytochemical defenses found in plants. A single plant may contain five or six biosynthetic groups of secondary metabolites and within each group these defenses may include many structurally related analogs and derivatives. Across the different species of higher plants, there is a bewilder- ing array of different substances and modes of actions of substances. During the course of our research on phytochemical defenses in specific plant families, we have become interested in the raison d’ˆetrefor this diversity, as have many other researchers (Romeo et al., 1996). How much do we know about different types of defenses in plants? How did they arise? Are some of these secondary metabolites “redundant,” with no function? How do they interact with one another? In this chapter, we will address some of these issues with observations on the defenses of several plant families against insects, using results from our own research and the published literature. In general, we do not have a comprehensive picture of the different types of defenses in plants. Over a decade ago, Soejarto and Farnsworth (1989) esti- mated that of the 250 000 species of flowering plants, only 5000 species had been thoroughly investigated according to the Natural Product Alert (NAPRALERT) database, leaving 98% of species with potential for phytochemical discovery. -

B, Asa Norte, 70790-160, Brasilia-DF, Brazil Abstract Mahogany (Swietenia macrophylla, Meliaceae) is the most valuable and intensively exploited Neotropical tree. No information is available regarding the genetic structure of mahogany in South America, yet the region harbours most of the unlogged populations of this prized hardwood. Here we report on the genetic diversity within and the differentiation among seven natural populations separated by up to 2100 km along the southern arc of the Brazilian Amazon basin. We analysed the variation at eight microsatellite loci for 194 adult individuals. All loci were highly variable, with the number of alleles per locus ranging from 13 to 27 (mean = 18.4). High levels of genetic diversity were found for all populations at the eight loci (mean ffE = 0.781, range 0.754-0.812). We found moderate but statistically significant genetic differentiation among populations considering both estimators of FST and RST, 9 = 0.097 and p = 0.147, respectively.
