“…O aumento da precipitação pode ser considerado fator determinante no estabelecimento de criadouros para simulídeos imaturos (larvas e pupas) e por conseqüência responsável pelo aumento da população de adultos (Py-dAniel & rAPP Py-dAniel 1998; Grillet et al 2001). As espécies de simulídeos enfocadas no presente estudo, possivelmente são afetadas pelo regime de chuvas: C. pydanieli tem oviposição associada a rios de grandes vazões, enquanto C. pertinax, que Alguns estudos constataram os efeitos de variáveis climáticas como umidade relativa do ar, temperatura e pressão atmosférica na ocorrência e atividade hematofágica de piuns (Medeiros et al 2006;AndreAzze et al 2002;MoreirA et al 1994). Nas comunidades de Tabajara e Dois de Novembro esses fatores não afetaram significativamente as capturas dos simulídeos.…”

A família Simuliidae é implicada como transmissores das filárias Onchocerca volvulus (Leuckart) e Mansonella ozzardi (Manson) na região norte do Brasil. Os objetivos do presente estudo foram (i) conhecer a fauna de simulídeos em duas comunidades ribeirinhas de Rondônia, (ii) avaliar a abundância e distribuição temporal (mensal e diária) de duas espécies de simulídeos e (iii) avaliar os possíveis efeitos da fatores climáticos na abundância dos simulídeos. As coletas dos simulídeos adultos foram realizadas entre setembro/2008 e dezembro/2009, das 08:00 às 10:00 e das 15:00 às 17:00. A espécie Cerqueirellum pydanieli Pessoa, Medeiros & Barbosa foi a mais abundante em todos os meses e locais. Foi coletado um maior número de indivíduos no período matutino para ambas as espécies (C. pydanieli e Chirostilbia pertinax Kollar) observando-se tendências de alteração nos picos de atividade diária em função da disponibilidade de chuvas. Nessas comunidades foram coletadas 11 espécies de Simuliidae, sendo constatada pela primeira vez, a ocorrência de C. pydanieli, Ectemnaspis rorotaense (Floch & Abonnenc) e Coscaroniellum ulyssesi (Py-Daniel & Coscarón) no estado de Rondônia. Occurrence and Antrhopophily of Simuliid Species in Riverine Communities from Rondônia State, BrazilAbstract. The family Simuliidae is implicated as containing the vectors of human filariid worms (Onchocerca volvulus Leuckart e Mansonella ozzardi Manson) in north region of Brazil. The objectives of this study were (i) to describe the occurrence of black fly species in two riverine communities from Rondônia; (ii) to evaluate the abundance patterns and temporal distribution (monthly and daily) of two blackfly species and (iii) to investigate possible climatic effects in the blackflies abundance. Adult collections were done during September/2008 to December/2009, in the diurnal period, 08:00 to 10:00 AM and 03:00 to 05:00 PM. Cerqueirellum pydanieli Pessoa, Medeiros & Barbosa was the most abundant species during all months, and in both riverine communities. More blackflies were sampled during the morning than afternoon for both species (C. pydanieli and Chirostilbia pertinax Kollar). It was observed a tendency to alteration in the daily activity peaks due to the rainfall period. In these communities were captured 11 Simuliidae species, which provide new records for the state of Rondônia: C. pydanieli, Coscaroniellum ulyssesi (Py-Daniel & Coscarón) and Ectemnaspis rorotaense (Floch & Abonnenc).

“…Andreaze et al (2002) related that biting activity of S.incrustatum is influenced by temperature, humidity, luminosity and nebulosity. Medeiros et al (2006) showed that the biting activity of Simulium argentiscutum Shelley & Luna Dias varied according to the precipitation (dry and rainy seasons), and that during the dry season, it was greater in the early morning, showing a positive association with humidity. However, during the rainy season, it was negatively associated with the same factor.…”

The Blackflies (Diptera: Simuliidae) are a cosmopolitan dipteran family, comprising 2102 described species. Although insects of this family are widely distributed, their immatures are restricted to areas where suitable lotic conditions allow their development. While the Onchocerciasis has been largely studied over the years, it still lacks a more integrated approach with the vector ecology. In this paper, we examine the ecological factors that potentially play a role in the disease dynamics. Our aim is to identify the ecological factors that are potentially important in the vector dynamics and the gaps in the current knowledge of blackfly ecology that could lead to a better understanding of the underlying factors behind the disease dynamics.

Ant-garden ants have a strong relationship with epiphytes that need light to grow, for these reason, it has been previously documented in forest gaps. Moreover, larger gaps have more available area for nesting and habitats for use as forage. Thus we hypothesize that 1) canopy openness influence the presence of ant´s gardens in gaps, and 2) greater gaps will have more nests, and 3) both openness canopy and area determine the colony size in forest gaps. Furthermore, it is known that parabiotic ants foraging on the ground and in vegetation, the nests are arboreal. So, we also hypothesize that 4) parabiotic ants are more often sampled in arboreal strata and 5) increasing vegetation connectivity and the volume of accumulated litter in the soil increase the foraging of the ants in vegetation and ground, respectively, with the increase in canopy openness increasing the activity of the two species in both strata. Presence, number of Ant-gardens, as colony size, was affected by area and locality, but not by canopy openness. Nevertheless, there was not overall difference in the use of strata by Camponotus femoratus, neither by Crematogaster levior. On the other hand, frequency of C. femoratus on the ground decreases with canopy openness but is not affected by the vegetation connectivity. Also, C. levior frequency on the ground also decreases with the increase of complexity of vegetation and canopy openness. In addition, neither vegetation connectivity, or canopy openness influence the frequency of foraging of these ants in understory.
