| entomopathogenic fungi of the order entomophthorales (zygomycotina) in adult black fly populations (diptera: simuliidae) in quebec. | infections by insect-pathogenic fungi of the order entomophthorales in two adult black fly populations were studied in the réserve faunique du saint-maurice (quebec). entomophaga near limoniae infected simulium verecundum/rostratum in june whereas erynia curvispora predominantly parasitized simulium decorum from the 2nd week of july to september and erynia conica attacked the simulium venustum complex, simulium verecundum/rostratum, and the simulium vittatum complex from may to september. the fu ... | 1994 | 7922891 |
| notes on sugar feeding and selected wild mammalian hosts of black flies (diptera: simuliidae) in newfoundland. | this study, done on the avalon peninsula, newfoundland, identified selected wild mammalian hosts and quantified the incidence of sugar feeding for several species (species complexes) of black flies. female flies were taken from fox, snowshoe hare, lynx, caribou, and human baits. simulium truncatum/venustum complex females took blood from fox, lynx, rabbit, and caribou and were frequently taken in sweep net collections around humans. blood-fed females of the simulium rostratum/verecundum complex ... | 1994 | 7932603 |
| development of erynia conica (zygomycetes: entomophthorales) on the cuticle of the adult black flies simulium rostratum and simulium decorum (diptera: simuliidae) | aerial conidia of erynia conica were showered onto the wings of susceptible and nonsusceptible black fly, simulium rostratum and simulium decorum, respectively. secondary type 2 conidia as opposed to type 1 conidia and primary conidia invaded the wings of s. rostratum. the invasion process on both sexes of the host species was rapid, with 40% of the conidia germinating during the 2 hr that the wings were showered with conidia. approximately 24% of total spores developed appressoria close to the ... | 1996 | 8812568 |
| prevalence of the trichomycete fungus harpella melusinae (harpellales: harpellaceae) in larval black flies (diptera: simuliidae) across a heterogeneous environment. | a total of 2063 mid- to late-instar larval black flies were collected from 64 stream sites in south carolina and screened for the presence of the trichomycete fungus harpella melusinae. sixteen of 18 host species were colonized by h. melusinae on at least one occasion. prevalence of h. melusinae in larvae of simulium tuberosum cytospecies "a" was highest in acidic streams with low conductivity, whereas h. melusinae colonized larvae of simulium verecundum most frequently in slower-moving streams. ... | 2003 | 21148966 |

| assimilation rates of different particulate foods for simulium verecundum (diptera: simuliidae). | particulate food assimilation rates for larvae of simulium verecundum stone & jamnback were studied using three radiolabelled particulate foods: navicula pelliculosa bréb. ex kütz.) hilse (a diatom), scenedesmus quadricauda (turp.) bréb. (a green alga), and field-collected, size-fractionated (< 3.0 microns) heterotrophic bacterioplankton. assimilation was determined by radiolabelling the microorganisms followed by a 5-h laboratory feeding of each food to fifth- to seventh-instar s. verecundum. t ... | 1993 | 8360907 |
