Results are presented for a 4-year (1986–1989) cytological survey of the Simulium venustum/verecundum complex on the Avalon Peninsula, Newfoundland, Canada. Based on 4578 larval identifications from 72 sites, six species in the S. venustum/verecund

Larval and pupal microhabitat selection by the cytospecies Simulium truncatum Lundström, S. rostratum Lundström, and S. verecundum AA was investigated. Last-instar larvae of S. truncatum and S. rostratum selected different microhabitats as shown by

The influence of temperature on survival, development, and growth of simuliid larvae of the EFG/C cytotype and of a mixed population of ACD–AA cytotypes was examined, employing a stir bar rearing system. The EFG/C type completed larval development

Ingestion of water by larvae of the black flies Simulium verecundum, Prosimulium mixtum/fuscum and Cnephnia dacotensis and by larvae of the mosquito Aedes aegypti was studied with radiolabelled glucose as a tracer. Extremely low (≤ 200 dpm/3 h) rad

Adult emergence of Simulium verecundum S. and J. and S. decorum Walk. was reduced 58–94% by exposure of late instar larvae to 0.1 ppm Altosid or Altosid SR-10 for 1 h. Pupae were not affected by the presence of 0.1 ppm Altosid SR-10 in the rearing

In 1982 and 1983, silhouette traps, sticky traps, and suction traps with and without dry-ice bait were evaluated for sampling populations of black flies that are pests of cattle in central Alberta. The dry-ice-baited silhouette trap was the most effe

Twenty-one blackfly species from 22 rivers and creeks and 3 additional species from small temporary streams were collected in southern Alberta from 1981 to 1983. Eight Prosimulium, 14 Simulium, 1 Twinnia, and 1 Stegopterna species were identified. Th

The effect of rearing the preimaginal stages of Simulium vittatum and Simulium verecundum at 15, 20, and 25 °C and at four feeding rates was examined. The results showed that flies reared on all diets were larger at the coolest temperature. The decr

A series of 10 similar rearing vessels, each containing 500 ml of water circulated by a rotating magnetic stirring bar, was used to rear cohorts of 50 first-instar Simulium verecundum larvae to adults. Ground 'TETRA' tropical fish meal was used as fo

Adult emergence of Simulium verecundum was reduced 75 to 100% by 0 001 to 0.1 ppm Altosid SR–10 at 25 ± 3 °C and 10 °C. No reduction in adult emergence was observed with 0.0001 ppm Altosid SR–10. 0.1 ppm of the granular R–20458 4–G reduced
