However, the mite fauna from this biome are still poorly known. Here, we present a checklist of mite species on Astronium fraxinifolium Schott, a Brazilian plant species threatened with extinction, from the Cerrado remnants associated with nickel mining areas, in the Niquelândia municipality, Brazil. Moreover, we performed cumulative (Mao Tau) and estimated (Jackknife 1) species accumulation curves in order to test for an effect of sampling effort and to estimate the potential number of species sheltered by the studied Cerrado remnants, and NMDS and ANOSIM analyses to test for similarity in mite species composition among samples. We sampled five A. fraxinifolium plants in each of six Cerrado remnants. Among these, three remnants were preserved (PR) and three were experiencing a secondary regeneration process (SR). Both PR and SR remnants were close to nickel mining areas. We recorded 1,562 mites including 17 species from 12 genera and eight families. Tetranychidae was the most diverse family, followed by Phytoseiidae and Tenuipalpidae. The most abundant species were phytophagous mites, namely Brevipalpus sp.1, Oligonychus sp., Eotetranychus sp.1, and the predator Agistemus brasiliensis Matioli, Ueckermann & Oliveira. Regarding feeding behavior, phytophagous mites were the most abundant and diverse on A. fraxinifolium. Both species accumulation curves (Mao Tau) for PR and SR remnants trended towards an asymptote, while estimated curves (Jackknife 1) proved to be similar to accumulation curves (Mao Tau). These results indicate that sampling was sufficient to assess mite assemblages using the methods applied in this study. No differences in mite species composition were observed between PR and SR areas. This paper is a pioneer report of mite assemblages on A. fraxinifolium. Furthermore, we report here two genera and one species recorded for the first time in the Cerrado biome. Our checklist can contribute to bridging the knowledge gap on the occurrence of plant mite species in Brazilian natural vegetation remnants.

Anacardiaceae 1.M By JEANNETTE M. KRYN, Forest Products Technologist Division of Silvicultural Relations Distribution and Habitat The genus Astronium, important as a source of useful timber, includes about 12 species of medium-sized to large trees. The genus is divided into two subgenera, Euastronium and Myracrodruon, The woods likewise show distinguish- ing features and can be separated into their respective subgenera by the presence or absence of characteristic blackish bands; Euastronium shows such bands, Myracrodruon lacks them. Astroniqm fraxinifolium Schott, with four botanical "forms," and A. graveolens Jacq. (including the variety Planchonianum Engl.) are the sources of the timber known as gonalo alves. Both species belong to the subgenus Euastronium and occur together throughout most of the range of the genus. They are best known commercially from the coastal mountain regions of eastern Brazil but occur also in upland forests of many regions from Mexico and Central America through Ecuador, Colombia, and Venezuela (2, 5, 10, 20, 30).2 1Maintained at Madison, Wis., in cooperation with the University of Wisconsin. 2 -Underlined numbers in parentheses refer to the list of numbered references at the end of the article.

    CHEMICAL COMPOSITION AND ANTIBACTERIAL ACTIVITY OF ASTRONIUM GRAVEOLENS JACQ ESSENTIAL OIL VANESSA HERNÁNDEZa*, FLOR MORAa, MARÍA ARAQUEb, SOUMI DE MONTIJOb, LUIS ROJASc, PABLO MELÉNDEZa AND NUNZIATINA DE TOMMASId (Received November 2012; Accepted July 2013) ABSTRACT In this paper is presented a study on the chemical characterization of Astronium graveolens Jacq essential oil, obtained by hydrodistillation of its aerial parts. The separation of the components was performed by GC-MS. Twenty-six compounds (99.3% of the sample) were identified of which, the major ones (84.8%). Weretrans - β-ocimene (23.9%), α-pinene (19.8%), δ-3-carene (15.5%), α-phellandrene (12.7%), cis-ocimene (6.4%), α-terpineol (3.3%) and p-cimene (3.2%). The essential oil showed a strong antibacterial activity, regardless of bacterial species or resistance mecha- nism. www.relaquim.com KEYWORDS: Astronium graveolens Jacq, Anacardiaceae, trans-β-ocimene, essen- tial oil, antibacterial activity, nosocomial infections. RESUMEN En este trabajo se presenta un estudio sobre la caracterización química del aceite esencial de Astronium graveolens Jacq, obtenido por hidrodestilación de sus partes aéreas. La separación de los componentes se realizó por CG-MS. Veintiséis com- puestos (99,3%) fueron identificados, de los cuales los más importantes (84,8%) fueron trans-β-ocimeno (23,9%), α-pineno (19,8%), δ-3-careno (15,5%), α-felandreno (12,7%), cis-ocimeno (6,4%), α-terpineol (3,3%) y p-cimeno (3,2%). El aceite esen- cial mostró una fuerte actividad antibacteriana, independientemente de la especie bacteriana o mecanismo de resistencia. www.relaquim.com PALABRAS CLAVES: Astronium graveolens Jacq, Anacardiaceae, trans-β-ocimeno, aceite esencial, actividad antibacteriana, infección hospitalaria.
