An investigative study on the effects of black fly (diptera: simuliidae) sugar meals on reproductive success and parasite transmission /
Black flies are opportunistic sugar-feeders. They take sugar meals from Homopteran honeydew secretions or plant nectars, depending on availability. Homopteran honeydew secretions contain both simple and complex carbohydrates while plant nectars contain primarily simple carbohydrates. In order to …

Influence of dietary nutrients on life history-related traits of black flies and mosquitoes
… of female Simulium venustum/verecundum (Diptera: Simuliidae) and female Anopheles stephensi (Diptera: Culicidae) on artificial nectar and honeydew. Paired choice experiments showed that the black flies forage more frequently from high calorie diets, which contained melezitose, or those diets that …

An investigation into the effects of homopteran honeydew sugars versus floral nectar sugars on black fly longevity, flight performance and digestion /
Floral nectar is thought to be the primary carbohydrate source for most dipteran species. However, it has been shown that black flies (Burgin & Hunter 1997 a,b,c), mosquitoes (Foster 1995; Burkett et al. 1999; Russell & Hunter 2002), deer flies (Magnarelli & Burger 1984; Janzen & Hunter 1998; …

Effects of black flies on wild turkey reproductive success
… Biting insects such as black flies (Diptera: Simuliidae) are a common nuisance often present during the reproductive period of numerous avian species and have the potential to directly (e.g., cause nestling mortality) and indirectly (e.g., increase rate of nest abandonment) affect reproductive …
