The Scolytinae is highly diversified in tropical forests, but richness and abundance patterns within most Ecuadorian forest habitat types are not yet characterized. In this study, we assessed of variation richness, abundance, species composition a primary secondary natural forest, commercial balsa plantation Ecuador. We conducted 1-yr survey communities with baited traps measured associated environmental variables. total, 18,169 individuals were captured comprised 85 species, 16 genera, six...
A new species of xyleborine ambrosia beetle has been found to attack balsa, Ochroma pyramidale (Cavanilles ex Lamarck) Urban, in Ecuador. Coptoborus ochromactonus Smith & Cognato is described and its biology reported. Large-scale surveys were conducted between 2006 2009, observational studies carried out 2010 2013 Ecuadorian commercial plantations determine life history host preference characteristics. C. attacked balsa 1.5 3 yr age. Successful attacks more prevalent smaller diameter trees...
Abstract Ambrosia beetles from the tribe Xyleborini are part of nearly all forest ecosystems. Because their small size, haplodiploid mating structure, and protected lives inside sapwood woody plants, they have a unique ability to expand into new regions via inadvertent human transport. A number invasive xyleborines cause significant damage forests, lumber concerns, agricultural systems. Most ambrosia pests or kill trees by accumulation beetle attacks, one is known tree death through...
Camarero, J.J., Sangüesa Barreda, G., Alla, A.Q,. González de Andrés, E., Maestro Martínez, M.,Vicente-Serrano, S.V. (2012). The precedents and the responses of trees to extreme droughts reveal processes involved in die-off Mediterranean conifer forests. Ecosistemas 21(3):000-000. Doi.: 10.7818/ECOS.2012.21-3.04 What drives tree species' vulnerability against climatic events within current context global warming? We are aware that severe contribute forest but we do not know growth decline...
The species of Scolytinae subfamily have a worldwide distribution, and are found mainly in the Neo-tropic regions. They usually dominate communities wood borer insects. aim present study was to determine diversity among associated with balsa, teak, rubber gamhar plantations located humid tropical zone Ecuadorian littoral. In each plantation seven flight interception traps containing an ethanol / gel mixture were installed, collection frequency 15 days for three months dry period. A total...
Coptoborus ochromactonus Smith and Cognato is a recently described xyleborine ambrosia beetle pest associated with balsa, Ochroma pyramidale (Cav. Ex Lam.) Urb., in Ecuador. This has caused significant loss of cultivated balsa Ecuador, but little known its biology ecology. Based on examination multiple gallery systems, this study describes the pattern life cycle C. confirms generic identity symbiotic fungus. Females initiated attack, excavating perpendicular to bole. The primary tunnel...
Coptoborus ochromactonus (Smith and Cognato) is one of the most common important pests balsa, Ochroma pyramidale (Cav. Ex Lam. Urb.), an economic pillar wood industry in Ecuador. Commercial balsa plantations have been expanded from humid to dry climate areas limit insect damage, but basic knowledge still lacking on interaction C. activity with variation plantation age. We investigated effects host age seasonal flight its infestation rate intensity, as well effect individual intensity...
Los polinizadores naturales cumplen un rol importante en la eficiencia reproductiva de Theobroma cacao. El objetivo esta investigación fue determinar cantidad y diversidad insectos T. cacao tipo Nacional, sistema monocultivo agroforestal, con énfasis los polinizadores. estudio se realizó finca experimental “La Represa” ubicada el cantón Quevedo, provincia Ríos, Ecuador. Se colocaron trampas emergencia captura dos sistemas cultivo. Además, realizaron observaciones directas las flores para...
ResumenSe evaluó la germinación y crecimiento de semillas balsa aplicando siete tratamientos pre-germinativos: inmersión en HSO4 por 32 minutos, agua a 80 °C durante tres testigo, remojo 100 15 coco 12 horas, lijado las hasta que pierdan su brillo natural, calor seco 96 5 minutos.Sembradas sustratos utilizando tierra negra sola combinada con: tamo arroz, arcilla más arena, humus UTEQ, zeolita, ceniza, nacaro (humus Lombriz).Se realizó un diseño completamente al azar (DCA) arreglo factorial 7...

La “Mazorca Negra” es una enfermedad que afecta al cacao (Theobroma L.), los agentes responsables son Phytophthora megakarya y palmivora. En África Central Oeste, estos Oomycetes por la pérdida de más del 80% producción. Esta investigación detalla metodología estandarizada para visualización conteo cromosomas estas dos especies género Phytophthora. El único órgano donde se diferencian en el momento meiosis “oospora”; hecho, no puede trabajar ni con micelios las esporas asexuales (esporangios...
