Autores: Figueiró,Ronaldo; Araújo-Coutinho,Carlos J.P.C.; Azevedo,Leonardo H. Gil; Nascimento,Érika S.; Monteiro,Ricardo F.
The distribution of the blackfly larval taxocenoses of different altitudes in the Itatiaia National Park (located in the southeast of Rio de Janeiro state, Brazil 44º34' - 44º42' W , 22º16' - 22º28' S) was investigated on four campaigns, one in each season of 2003. On each campaign 60 samples were collected, using 30 x 30 cm wooden quadrats, distributed at four sites: Taquaral, Véu da Noiva, Três Picos and Brejo da Lapa. The winter and spring campaigns included two additional sampling sites: Alsene and Agulhas Negras. A total of 3578 larvae and 292 pupae were sampled, representative of six species: Simulium clavibranchium Lutz, S. subnigrum Lutz, S. rappae Py-Daniel, S. incrustatum Lutz, S. stellatum Gil-Azevedo, Figueiró &amp;amp; Maia-Herzog and...

Autores: Araújo-Coutinho,Carlos J.P.C.; Figueiró,Ronaldo; Viviani,Andréia P.; Nascimento,Érika S.; Cavados,Clara F.G.
This note presents an alternative method for bioassays using black fly larvae, with which we intend to provide a simpler but effective tool for accessing data on larvicide efficacy.

Evidence of phenotypic plasticity of larvae of Simulium subpallidum Lutz in different streams from the Brazilian Cerrado
Provedor de dados: 92

In this paper, the overall morphological differences between populations of Simulium subpallidumLutz, 1909 are studied. Several studies found in the literature point to a relationship between the labral fans and body size and the habitat where blackfly larvae occur. However, other characteristics potentially related to the microhabitat, such as abdominal hook circlet morphology, which is used for larvae to fix themselves in the substratum, and thoracic prolegs morphology, which help larvae move in the substratum, were analyzed in three different populations of S. subpallidum, one of which occupied a faster flow. The results suggest phenotypic plasticity in S. subpallidum and a tendency toward larger structures in faster flows.

Local distribution of blackfly (Diptera, Simuliidae) larvae in two adjacent streams: the role of water current velocity in the diversity of blackfly larvae
Provedor de dados: 92
Autores: Figueiró,Ronaldo; Nascimento,Érika Silva do; Gil-Azevedo,Leonardo Henrique; Maia-Herzog,Marilza; Monteiro,Ricardo Ferreira.
This study aimed to evaluate the influence of water velocity speed on the local distribution and taxocenosis structure of blackfly larvae. The larvae were collected from two adjacent streams located in the municipality of Angra dos Reis (RJ): Caputera River and one of its tributaries. Riffle litter patches were sampled randomly using a 30 x 30 cm quadrat. Four blackfly species were found: Simulium incrustatum s. l. Lutz, 1910; Simulium (Inaequalium) sp. ; Simulium pertinax s. l. Kollar, 1832 and Simulium subpallidum s. l. Lutz, 1909. Among these species, Simulium pertinax s. l. was clearly associated with higher water current speeds, while Simulium subpallidum s. l. showed association with lower water velocities, and Simulium (Inaequalium) sp. had a...
