La estación científica de Wayquecha se sitúa en el departamento de Cusco, en el sudeste de Perú, a una altitud de 2900 m (13°10.506'S - 71°35.210'W). En esta estación, encontramos una oruga de Leptotes callanga (Dyar, 1913) (Lepidoptera : Lycaenidae : Polyommatinae), alimentándose de flores de Genista monspessulana (L.) L.A.S. Johnson (Fabaceae), una planta no nativa, de origen mediterráneo. La crianza permitió obtener una hembra adulta de L. callanga. La oruga en el último estadio y la crisálida se describen e ilustran. Se comenta la adaptación de esta especie a una nueva planta.

Nutritional Benefits

The search for forages with high biomass production and high nutritional content has made it possible to find food alternatives that, due to their nutritional benefits and resistance to adverse environmental factors, are the best option for herbivores. With the knowledge of farmers, producers and the experience of researchers, 12 species most frequently used in animal feeding were selected, identified and classified in the University's PSO herbarium of the University of Nariño. These were phenologically, nutritionally and antinutritionally characterized. Of these species, four belonged to the Asteraceae family; the Fabaceae, Adoxaceae and Malvaceae families were represented by two species; the Salicaceae and Cucurbitaceae families were represented by one and were propagated in nursery. In the nutritional composition, the Retamo (Genista monspessulana) stood out for its high dry matter content with 34.2%. Unlike the Chauchilla (Cyclanthera brachystachya), with 8.79%, the Sauco (Sambucus peruviana) had a higher content of protein 25.93%, followed by Abutilon (Abutilon pictum) with 23.42%. Chauchilla (Cyclanthera brachystachya) had the highest crude fiber content, with 21.59%, NDF of 38.06%, and FDA 27.23%. Tannins were the most common secondary metabolites in the species evaluated with moderate or low levels; sterols were present at low levels, and saponins and alkaloids yielded negative values.

A review of 29 European species of the genus Phyllonorycter Hübner, 1822 developing on the plants of the tribe Genisteae with diagnostic characters, brief data on their biology and distribution is given. Twelve of them are new: Phyllonorycter estrela sp. n., probably from Genista cinerea (Vill.) DC., P. telinella sp. n. from Genista monspessulana (L.) L. A. S. Johnson, P. tridentatae sp. n. from Genista tridentata L., P. deschkanus sp. n. from Genista cinerea (Vill.) DC., P. andalusicus sp. n. probably from Retama sphaerocarpa (L.) Boiss., P. echinosparti sp. n. from Echinospartum lusitanicum (L.) Rothm., P. baetica sp. n. from Genista versicolor Boiss., P. vueltas sp. n. from Genista florida L. and G. cinerea (Vill.) DC., P. scorpius sp. n. from Genista scorpius (L.) DC., P. pumila sp. n. from Genista versicolor subsp. pumila (Hervier) Fern. Casas, P. eugregori sp. n. from Cytisus austriacus L. and C. ratisbonensis Schaeff., and P. etnensis sp. n. from Genista aetnensis (Biv.) DC. Phyllonorycter purgantella (Chrétien, 1915) is recognized as bona species. Phyllonorycter dalmatinella (Amsel, 1951) and P. picardi Buvat, 1995 are junior subjective synonyms of Phyllonorycter lapadiella (Krone, 1909). The lectotype of Phyllonorycter haasi (Rebel, 1901) is designated. The species are divided into three species groups, Phyllonorycter cerasinella (Reutti, 1853) standing apart from these groups. New country records of several species are given.

Introducción. El fenómeno del Niño de 2014-2015 evidenciado en los niveles nacional y regional tuvo impactos en ecosistemas hídricos y en las coberturas vegetales asociadas al mismo. Objetivo. Con el objetivo de establecer la relación entre la variación de la vegetación riparia y la variabilidad climática en el humedal urbano Torca-Guaymaral, se realizó la caracterización florística de la vegetación riparia asociada a este ecosistema estratégico para el borde norte de la ciudad de Bogotá. Posteriormente se plantea una propuesta metodológica de restauración enfocada a restablecer la estructura y función de la vegetación riparia, a través de la sucesión asistida. Materiales y métodos. Durante 2014-2015 se realizaron muestreos en dos épocas climáticas (húmeda y seca) en 21 unidades de muestreo para evaluar las coberturas vegetales con mayor desarrollo estructural, composición y riqueza. Los resultados reportan que existe una alta presencia de especies invasoras (Ulex europaeus y Genista monspessulana), lo cual ha generado una eliminación total de las especies nativas, una disminución en la diversidad del humedal, lo que imposibilita la llegada de nuevas especies. Resultados. Adicionalmente se encontró una relación positiva entre el incremento en la temperatura y la colonización. Asimismo, se reporta una alta dominancia en área y abundancia de las especies invasoras, lo que impide la recuperación del área con especies nativas y reduce los servicios ecosistémicos del humedal. Conclusión. Reconociendo los conflictos en el área, en este estudio se plantea una metodología para la recuperación de la vegetación riparia del sector occidental del humedal Torca-Guaymaral, en donde se involucra la sucesión vegetal asistida, el manejo de las especies invasoras y la siembra de nuevas especies.

Gorse (Ulex europaeus) and French broom (Genista monspessulana) are two highly invasive species that have become a threat to tropical countries, especially in Andean ecosystems. This research focused on providing a physicochemical characterization and essential oils extraction of both species to better understand their potential valorization and guide further environmental management efforts. For this purpose, the following analyses were conducted for both species: higher heat value (HHV), elemental analysis, proximate analysis, thermogravimetric analysis to obtain constituent natural polymers (hemicellulose, cellulose, and lignin), and extraction of essential oils and other interest chemical compounds through supercritical fluids. Ecological closeness was found between the two species mostly regarding HHV, fixed carbon, and volatile matter, which calls for similar potential uses. Both species were also found to be suitable for combustion processes, gasification, extraction of chemical compounds, and use of lignocellulosic content; however, only U. europaeus appeared suitable for activated carbon obtention. Therefore, this work provided relevant data that can be used as preliminary basis to establish strong scientifically-based management and control strategies for these two invasive species. We recommend focusing primarily on thermal processes such as pyrolysis, gasification, or combustion, and also essential oils extractions of acetic acid, dodecanoic acid, anagyrine, amylene hydrate, caulophylline, and maltol in the future.
