Two newly recorded species of plants in Jiangxi province / 中国中药杂志

Based on the investigation of wild medicinal plant resources in Dexing city, Jiangxi province, and the collected plant specimens, which were identified by taxonomy, two new record species of geographical distribution were found, which are Meehania zheminensis A. Takano, Pan Li & G.-H. Xia and Corydalis huangshanensis L.Q.Huang & H.S.Peng. The voucher specimens are kept in Dexing museum of traditional Chinese medicine. In this paper, the new distribution species were reported, which provides valuable information for further enriching and supplementing the species diversity of medicinal plant resources in Jiangxi province.

First report of colored pan traps to capture Drosophilidae (Diptera)

ABSTRACT The use of robust sample methodologies to estimate the highest number of species with different ecological requirements and traits is essential to the knowledge construction of the biodiversity and to establish wildlife assessment and monitoring programs. Our aims were to study the performance of colored pan traps in the capture of Drosophilidae (Diptera), a method never used for sampling this taxon. During six months, colored pan traps (blue, yellow and white) were tested in three areas in Southern Brazil. We captured 375 individuals of 30 species belonging to four genera of Drosophilidae. The most abundant species were Drosophila lutzii (n=215) p=0.58, Scaptomyza sp. (n=55) p=0.15 and D. bromelioides (n=17) p=0.04, all of them, anthophilous species. All colored pan traps captured a high quantify species of Drosophilidae, mainly anthophilous species.

The beetle Costalimaita ferruginea (Coleoptera: Chysomelidae) in Eucalyptus plantations in transition area of Amazon and Cerrado Biomes / O besouro Costalimaita ferruginea (Coleoptera: Chysomelidae) em plantios de Eucalyptus em áreas de transição dos Biomas Amazon e Cerrado

Abstract Costalimaita ferruginea (Coleoptera: Chrysomelidae) attacks Eucalyptus plants causing severe damage through netting of the leaves. Recently, this Coleoptera has been reported attacking Myrtaceae in Mato Grosso State and, studies about the occurrence of this beetle in commercial plantations of eucalypts has been the subject of researchers through monitoring programmes in the forest protection area. With the beginning of the rainy season, adults were observed causing damage in eucalypt plantations in four cities that are part of the transition region of Amazon and Cerrado Biomes. The spots where these insects were observed are located in Feliz Natal, Lucas do Rio Verde, Sorriso and Vera. The purpose of this study was to report the new occurrences and to characterize the attack period of the beetle C. ferruginea in Eucalyptus plantations in Middle-North region of Mato Grosso State, region of Biomes Transition.

Recentemente, esse Coleoptera tem sido relado atacando Myrtaceae no Estado de Mato Grosso e, estudos sobre a ocorrência desse besouro em plantios comerciais de eucaliptos tem sido alvo de pesquisadores através de programas de monitoramento na área de proteção florestal. Com o início do período chuvoso, adultos foram observados causando danos em plantios de eucalipto em quatro municípios que fazem parte da região de transição dos Biomas Amazônia e Cerrado. Os pontos onde foram observados esses insetos estão localizados em Feliz Natal, Lucas do Rio Verde, Sorriso e Vera. O objetivo deste trabalho foi relatar as novas ocorrências e caracterizar o período de ataque do besouro C. ferruginea em plantios de Eucalyptus na região Médio-Norte do Estado de Mato Grosso, região de transição de Biomas.

Investigation on Medicinal Plant Group and Resource of Sect. Euthya Medicinal Plants in Paris L. from Shaanxi Province / 中国中医药信息杂志

Objective To investigate the medicinal plant group and resource of Sect. Euthya in Paris L. in Shaanxi Province. Methods Through literature analysis and interview survey, combined with line transect method, the medicinal plant group, the natural distribution and the status of medicinal plant group and resources about Sect. Euthya in the specific county territory in Shaanxi Province were investigated.Results According to related records about the medicinal plants of Sect. Euthya in Paris L. included P. polyphylla, var. stenophylla, var. apetala, and Paris fargesii var. petiolatain in Shaanxi Province. Based on field investigation, it was found that, the medicinal plants of Sect.Euthya in Paris L.also included five variations of P.polyphylla var.latifolia,var.apperdiculata,var. thibetica, var. chinensis, and var. yunnanensis, which were new distribution records. No var. apetala was found under field investigation. Most of the rhizomes of the Sect. Euthya plants were used as Chinese materia medica Paridis Rhizoma, with wide distribution and good growth condition. The natural resources of these plants are endangered. Conclusion In this study, two species and six variations in the Sect. Euthya are identified as new distribution records. Consequently, the medicinal plant distribution record of Paris L. in Shaanxi Province is complete. The natural resources are investigated, which have laid the foundation for further research, development and protection.

Diversity of Drosophilidae (Insecta, Diptera) in the Restinga forest of southern Brazil

Abstract Although members of Drosophilidae are frequently the topic of ecological studies in Brazil, few have explored Restinga or, until only recently, Pampa biome environments. This study proposes to describe the diversity and temporal variation of the Drosophilidae assemblage from a Restinga forest of Rio Grande do Sul, Brazil. We performed monthly collections from February 2013 to January 2014 using yeasted banana-baited traps. A total of 25,093 individuals of 46 species were sampled. Drosophila simulans and the D. willistoni subgroup were the dominant taxa; D. polymorpha, D. immigrans, D. paraguayensis and Zygothrica orbitalis were of intermediate abundance, and the other 40 species were rare. Based on sampling effort estimators, our collections were sufficient. Jaccard and Morisita indices evaluated using ANOSIM reveal little similarity in the composition of samples across months. Canonical correspondence analysis shows that the variables of maximum and minimum temperature are the main factors responsible for differentiation of the species composition of the assemblage throughout the year, whereby collections in the coldest periods (July, August and September) are those with a more differentiated composition. In these months, the dominance of D. simulans and the D. willistoni subgroup decreases while increased abundance of the D. tripunctata group (as D. paraguayensis) and Z. orbitalis occurs. In comparison to other studies carried out in environments in southernmost Brazil, we observed a similar pattern of fluctuation in abundance over the year, with a higher abundance of dominant species in warmer months and population sizes decreasing in colder months.
