Colonization Of Immature Black Flies (Diptera: Simuliidae) On Artificial Substrates In A Nebraska Sandy River, K. P. Pruess
Colonization Of Immature Black Flies (Diptera: Simuliidae) On Artificial Substrates In A Nebraska Sandy River, K. P. Pruess
Department of Entomology: Faculty Publications
Colonization of Simulium bivittatum Malloch and S. luggeri Nicholson and Mickel on artificial substrates exposed for two consecutive time periods of 1, 2, or 4 d was contrasted with colonization after continuous exposures of 2, 4, or 8 d. Reduced colonization of early instars of both species during the second 4-d period was attributed to an aging population, whereas reductions in total black flies after 8 d seemed to be caused by substrate changes. Numbers of pupae increased as exposure time increased.
