Chromosomal comparisons among and within populations of Simulium (Chirostilbia) pertinax (Diptera, Simuliidae).
Chromosomal studies were carried on six larval populations of Simulium (Chirostilbia) pertinax from different locations in Brazil. Larvae were collected in the states of Paraná, Rio Grande do Sul, Rio de Janeiro and São Paulo. Polytene chromosome map comparisons within and among populations showed no differences in banding pattern, except for some limited polymorphism (secondary NOR and four ba...
متن کاملEffects of Polydispyrenia simulii (Microspora; Duboscqiidae) on development of the gonads of Simulium pertinax (Diptera; Simuliidae).
The effects of the infection caused by the microsporidium Polydispyrenia simulii in gonads of the simuliid Simulium pertinax were evaluated. This blackfly species is the main target of control programmes in southeastern Brazil. Infected and noninfected blackflies were reared from larval stage to adults using a laboratory rearing system. There was no significant difference between the oogenic de...
متن کاملDescription of microsporidia in simulids: molecular and morphological characterization of microsporidia in the larvae of Simulium pertinax Kollar (Diptera: Simuliidae).
INTRODUCTION Microsporidia constitute the most common black fly pathogens, although the species' diversity, seasonal occurrence and transmission mechanisms remain poorly understood. Infections by this agent are often chronic and non-lethal, but they can cause reduced fecundity and decreased longevity. The objective of this study was to identify microsporidia infecting Simulium (Chirostilbia) pe...
متن کاملInfluence of temperature on microsporidia infections in a natural population of Simulium pertinax Kollar, 1832 (Diptera; Simuliidae).
During the studies involving the correlation between the water temperature of the breeding site of Simulium pertinax larvae and the infection prevalence by microsporidia, developed in the Andorinhas river, Magé, RJ, weekly samples of blackfly larvae were taken within a two-year period (2001-2002 and 2003-2004), and it was noticed that the infections by Amblyospora sp. were more prevalent when c...
متن کاملSimulium pertinax Kollar. Six species in this subgenus are known from for the state of Mato Grosso (MT), Bra- zil (Simulium dekeyseri Shelley & Py-Daniel, Simulium friedlanderi Py-Daniel, S. pertinax, Simulium serranum Coscarón, Simulium spinibranchium Lutz and Simulium subpallidum
According to Adler and Crosskey (2011), three genera of Simuliidae occur in Brazil: Araucnephia Wygodzinsky & Coscarón, Lutzsimulium d’Andretta & d’Andretta (2 subgenera) and Simulium Latreille (8 subgenera). The subgenus Simulium (Chirostilbia) is represented by 13 species, all of which are found in Brazil, including one economically important species, the pest Simulium pertinax Kollar. Six sp...
