Estimating the gonotrophic cycle and survivorship of Simulium ochraceum (Diptera: Simuliidae) during routine vector surveillance in southern Mexico.
The gonotrophic cycle, survivorship, and daily parity rate of Simulium ochraceum were estimated from specimens collected during routine vector surveillance in southern Mexico, using a vertical (time-specific) method. Series of sequential data analysis on parity of the entomological data obtained in February 1994 showed the highest significant (P < 0.05 alpha) correlation indices (r = 0.63 and r...
متن کاملIdentification of entomopathogenic Bacillus isolated from Simulium (Diptera, Simuliidae) larvae and adults.
Entomopathogenic bacteria isolated from Simulium larvae and adults from breeding sites in the states of São Paulo and Rio de Janeiro, Brazil, were identified as 18 strains of Bacillus thuringiensis and one of B. sphaericus. Most of these strains were serotyped according to their flagellar antigens. However, nine of the B. thuringiensis samples, could not be serotyped and were designated as "aut...
متن کاملAvoidance of scouring by larvae of Simulium vittatum (Diptera: Simuliidae) during a spring flood.
The larva of the blackfly Simulium uittatum Zett (Diptera: Simuliidae) is an abundant and readily collected benthic inverrebrare in many parts of North America (Wood et al. 1962). it has been collected from the solid submerged substrates in the Nanticoke River at Waterford, Ontario during all seasons of the year over several years by the authors and other blackfly workers (R. Faraday, personal ...
متن کاملCytotaxonomy of Simulium cauchense Floch & Abonnenc and Simulium quadrifidum Lutz (Diptera: Simuliidae) in Brazilian Amazonia.
Simulium cauchense Floch & Abonnenc and Simulium quadrifidum Lutz are widely distributed in the Amazon region and are morphologically similar at the larval and pupal stages. Chromosomally, these species are readily distinguished by the position of the nucleolar organizer, which is in the short arm of chromosome I in S. cauchense and in the long arm of chromosomes III in S. quadrifidum. They als...
متن کاملThree new species of Simulium (Nevermannia) (Diptera: Simuliidae) from Vietnam.
Three new species of black flies, Simulium (Nevermannia) langbiangense, S. (N.) phami, and S. (N.) bachmaense, are described on the basis of females, males, pupae and larvae collected in Vietnam. All three species are assigned to the Simulium feuerborni species-group of Simulium (Nevermannia). Simulium (N.) langbiangense sp. nov. is characterized by the female sensory vesicle with a large openi...
