Vascular Flora Of The Legado Das Águas, Reserva Votorantim, Municipalities Of Tapiraí, Miracatú And Juquiá, São Paulo, Brazil

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)We present a list of vascular plants found in Legado das Águas, Reserva Votorantim, a private reserve having an area of approximately 35,000 ha that spans the municipalities of Tapiraí, Miracatú, and Juquiá, in the state of São Paulo, Brazil. The reserve is part of a complex of state-protected areas including Alto Ribeira Touristic State Park, Intervales State Park, Carlos Botelho State Park, Jurupará State Park, and Serra do Mar State Park. Together, these form an important and large area of continuous and well-preserved forest. Our study, which involved two main floristic surveys in March/April 2013 and April 2014, recorded 768 species, representing 131 families and 432 genera. The majority of species were angiosperms (619) representing 106 families and 370 genera. There were also two species of gymnosperms belonging to two genera in separate families; 147 species of ferns and lycophytes belonging to 23 families and 60 genera. In demonstrating the presence of almost 800 species of plants, of which 16 are threatened, our study highlights the importance of floristic surveys and the critical role of private protected areas in managing and preserving native flora. © 2016 Check List and Authors.1262011/22923-8, FAPESP, Fundação de Amparo à Pesquisa do Estado de São Paulo2015/9444-4, FAPESP, Fundação de Amparo à Pesquisa do Estado de São PauloFundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP

Diversidade de formigas na Floresta Nacional de Chapecó, Santa Catarina, Brasil Ants diversity in Floresta Nacional de Chapecó in Santa Catarina State, Brazil

A mirmecofauna da Floresta Nacional de Chapecó, Gleba I, foi estudada por coletas semanais realizadas de dezembro de 2003 a dezembro de 2004. Foram utilizadas armadilhas do tipo malaise, pit-fall, iscas com sardinha, iscas com glicose, rede de varredura, guarda-chuva entomológico e funil de Berlese. Três constituições vegetais foram amostradas, sendo pinus, eucalipto e Floresta Ombrófila Mista e Floresta Estacional Decidual. Foram capturadas 137.019 espécimes de nove subfamílias, 18 tribos, 36 gêneros e 121 espécies. Os índices de diversidade de Margalef obtidos foram 9,9; 9,7 e 12,6; de Shannon e Wiener 3,0; 3,2 e 3,4 e de equitabilidade de 0,69; 0,73 e 0,74, para as áreas com pinus, eucalipto e mata nativa, respectivamente. Estes resultados indicam uma distribuição mais uniforme na comunidade da mata nativa, caracterizando-se como um importante reservatório espécies de formigas no Oeste catarinense.<br>Mirmecofauna of the Floresta Nacional de Chapecó, Field I, was studied by weekly collections from December of 2003 to December of 2004. Malaise, pit-fall, sardine baits, glucose baits, sweeping net, entomological umbrella and Berlese funnel had been used. Three vegetal constitutions where showed, like pinus, eucalyptus Ombrófila Mista and Estacional Decidual native forests. 137.019 specimens of nine subfamilies, 18 tribes, 36 generas and 121 species were captured. The indices of diversity of Margalef were 9.9; 9.7 and 12.6; of Shannon and Wiener 3.0; 3.2 and 3.4 and of equitability of 0.69; 0.73 and 0.74, for the areas with pinus, eucalyptus and native forest, respectively. These results indicate a more uniform distribution in the community of the native forest, characterizing itself as an important reservoir species of ants in the West region of the Santa Catarina State, Brazil

In vitro evaluation of the effects of some acaricides on life stages of Rhipicephalus sanguineus (Acari: Ixodidae) Avaliação in vitro do efeito de alguns acaricidas nos estádios de vida do Rhipicephalus sanguineus (Acari: Ixodidae)

The action of five acaricides was evaluated on eggs, larvae, nymphs and adults of the ixodid tick Rhipicephalus sanguineus. The acaricides tested were: high cis-cypermethrin (0.01%) + DDVP (0.11%), coumaphos (0.05%), deltamethrin (0.0025%), amitraz (0.025%) and cypermethrin (0.015%). Eggs treated with high cis-cypermethrin and cypermethrin showed eclosion inhibitions of 72.1% and 67.3%, respectively, whereas coumaphos was much less effective (only 11.7%). Except for coumaphos, which resulted in 63.3% and 80.0% mortality of nymphs and unfed females, respectively, all compounds tested killed 100% of all tick stages to which they were exposed.<br>Avaliou-se a ação de cinco acaricidas em ovos, larvas, ninfas e adultos do carrapato Rhipicephalus sanguineus. Os produtos testados foram: cipermetrina high cis (0.01%) + DDVP (0.11%), coumaphos (0.05%), deltametrina (0.0025%), amitraz (0.025%) e cipermetrina (0.015%). Os ovos tratados com cipermetrina high cis e cipermetrina mostraram inibição de eclosão de 72,1% e 67,3%, respectivamente, enquanto coumaphos resultou em baixa eficiência (11,7%). Exceto para ninfas (63,3%) e para fêmeas não alimentadas (80,0%) expostas ao coumaphos, todos os outros estádios de carrapato e fêmeas não alimentadas foram sensíveis a todos os produtos químicos testados
