Faunistic analysis of Formicidae (Hymenoptera: Apocrita) in degraded ecosystems of Chapecó town, Santa Catarina, Brazil
Junir Antonio Lutinski,Flávio Roberto Mello Garcia
Biotemas , 2005,
Abstract: Seeking to investigate the ant fauna in degraded environments and to comprehend how this group behaves in such ecosystems, faunistic analysis was initially conducted with the ants collected in an area in Chapecó town that had been subjected to flooding in function of the construction of the mouth of a dam on the Chapecó River (a branch of the larger Uruguay River). The collections were carried out between October 2001 and September 2002. We used pit-fall traps, sweeping nets, entomologic umbrellas and leaf litter collections for fragments covered by bushes and grass. The fauna was characterized through the constancy and dominancy indexes. A number of 34.642 specimens of ants, belonging to 32 species, 19 genera and six subfamilies, were collected. The species Labidus sp., Atta sp. and Ectatomma edentatum stood out as being either accessory or both constant and dominant.

Abstract: Realizou-se a análise faunística de gafanhotos coletados em três constitui es vegetais da Flona de Chapecó. Coletas semanais foram realizadas em áreas de eucalipto, mata nativa e pinus durante o período de dezembro de 2003 a dezembro de 2004. Utilizaram-se armadilhas do tipo “pitfall”, rede de varredura, guarda-chuva entomológico e “malaise”. A fauna encontrada nas diferentes áreas foi caracterizada por meio dos índices de abundancia, constancia, dominancia e frequência. Dezoito espécies foram comuns para as três áreas. As espécies Staurorhectus logicornis logicornis, Cylindrotettix sp. e Ommexecha virens ocorreram apenas em eucaliptos e pínus, enquanto, Scotussa lemniscata e Zoniopoda tarsata ocorreram para eucaliptos e mata nativa enquanto Amblytropidia sp. ocorreu somente em mata nativa e pínus. Tridactylus politus ocorreu somente em pínus. As espécies Allotruxalis gracilis, Dichroplus elongatus, Dichroplus misionensis e Ronderosia bergi foram muito frequentes, dominantes e muito abundantes na área de eucaliptos. A. gracilis, Metaleptea adspersa e D. misionensis foram muito frequentes, dominantes e muito abundantes na área de mata nativa. Metaleptea adspersa e R. bergi foram muito frequentes, dominantes e muito abundantes na área de pínus. Observou-se uma semelhan a na diversidade de espécies entre as áreas, com maior abundancia para a área de eucaliptos. doi: 10.4336/2011.pfb.31.65.43 A study of the grasshopper fauna was performed through samples collected in three vegetal types in the National Forest of Chapecó. Weekly collections were carried out from December 2003 to December 2004. Pitfall traps, sweep nets, entomological umbrellas and malaise traps were used. Collections were repeated in areas with eucalyptus trees, native species and pine trees. The fauna found in different areas was classified by its abundance, constancy, dominance and frequency. Eighteen species were common in the three areas. Staurorhectus longicornis longicornis, Cylindrotettix sp. and Ommexecha virens were found only in eucalyptus and pine areas. Scotussa lemniscata and Zoniopoda tarsata were found in areas with eucalyptus and native trees. Amblytropidia sp. was found only in native vegetation and pines areas. Tridactylus politus was found just in the pine area. Allotruxalis gracilis, Dichroplus elongatus, Dichroplus misionensis and Ronderosia bergi were very frequent, dominant and very abundant in the eucalyptus tree area. A. gracilis, M. adspersa and D. misionensis were very frequent, dominant and very abundant in the native tree area. Metaleptea adspersa and R. bergi w

Ciência Rural , 2006,
Abstract: Conhecido como psilídeo-de-concha, Glycaspis brimblecombei é um inseto sugador de origem australiana e ataca várias espécies de eucalipto. Sua presen a no Brasil foi registrada pela primeira vez no Estado de S o Paulo em junho de 2003. Posteriormente, sua ocorrência foi registrada também para os Estados de Minas Gerais, Goiás, Paraná e Mato Grosso do Sul. As ninfas possuem colora o amarelada e encontram-se protegidas sob pequenas conchas enquanto os adultos, com colora o marrom-alaranjado a amarelo-esverdeado, medem cerca de três milímetros de comprimento. Dentre os principais danos que causam às plantas est o a queda prematura das folhas, redu o da área fotossintética e superbrotamento. Em alguns casos, pode levar à morte da planta. No Estado de Santa Catarina, o G. brimblecombei foi encontrado atacando algumas plantas de Eucalyptus tereticornis localizadas no pátio de uma empresa no perímetro urbano da cidade de Chapecó.

Biotemas , 2010,
Abstract: Vulgarly known as “vaquinha”, Diabrotica speciosa (Germar, 1824) spread itself to the majority of Brazilian states, and it became distinguished as one of the most serious pests affecting beans and maize. The aim of this study was to evaluate the insecticidal activity of the crude watery extracts of nine vegetable species on “vaquinha” adults. The laboratory experiment was carried out in completely randomized delineation, with ten treatments and four repetitions. For such, a bottle was used, containing five insect specimens and a common bean leaf (Phaseolus vulgaris Linnaeus) previously immersed in the extract, covered with a clipping of porous cloth and fixed by a rubber band. The evaluated variable was the number of surviving D. speciosa specimens. The treatments consisted of salvia (Salvia officinalis Linnaeus), cravo (Eugenia caryophyllata Thunb), moscada nut (Myristica fragans Houtt), cinamomo (Melia azedarach Linnaeus), timbo (Ateleia glazioveana Baill), eucalyptus (Eucalyptus citriodora Hook), cinnamon (Cinnamomum zeylanicum Blume), figueira (Ficus microcarpa Linnaeus f.), rosemary (Rosmarinus officinalis Linnaeus) and control (distilled water alone). The evaluations of survival were carried out every 24 hours over a period of 10 days. For the live specimen number, two-way analysis of variance (10 extracts x 11 times after application) was used. The averages were grouped by the Duncan test on the level of 5% of probability. The most efficient extracts were timbo, moscada nut and cinamomo, with efficiency percentages varying between 80.4% and 100%.

Biotemas , 2009,
Abstract: The Myrmecofauna of Santa Catarina State has been studied for more than sixty years; however, studies on urban ant species only began last decade in the state. This study was carried out due to the need of new research in this field for the purpose of elucidating the urban myrmecofauna of Xanxerê, in the west of Santa Catarina. Samples were taken from January to December of 2006, using sardine baits and direct sampling. The sampled urban communities were characterized by high species diversity (Shannon & Wiener – H’) and species richness (Jackknife 1 and Bootstrap) values. These communities yielded a total of 67 ant species, distributed in 21 genera, 13 tribes and six subfamilies: Myrmicinae (33), Formicinae (17), Dolichoderinae (10), Ponerinae (4), Pseudomyrmecinae (2) and Ectatomminae (1). The species diversity was 3.17. The observed ant species richness in houses, commercial establishments and samples showed that the sampling protocol was satisfactory, due to the stability of approximation to the species accumulation curves of estimated species richness. Typical species which are common in areas of stress and also species that cause harm to man were found, as well as habitat specialists and those associated with the vegetation.

Abstract: The present study aimed to elucidate the richness of ant fauna associated with the micro basin of Sanga Caramuru in the town of Chapecó that represents one of the principal tributaries of the S o José dam. A total of 21 biweekly collections were made from June 2006 until May 2007, using Pit-fall traps. Analyzes of the data were carried out by the EstimateS statistics program (Colwell). A total of 676 registers of species were obtained through the traps. The richness obtained was 51 species distributed in 18 genera grouped in seven subfamilies. The richness estimated through the estimator Chao 2 was 61.6 species for the area of native forest, 42.3 species for the area of marsh, and 39.8 species for the area with eucalyptus. The Shannon and Wiener index obtained was 3.2 for the three sampled areas. The greater diversity estimated for the area with native forest coincided with the greater diversity also observed. Although the human impacts are easily evidenced in the studied area, the small fragments of areas with vegetation offer adequate resources for the maintenance of significant ant fauna.
