Abstrakt: The incidence of entomopoxvirus infections in larval midge populations of an undescribed species in the Chironomus decorus complex from 2 southern California flood-control channels was monitored during 2 successive summers. The population densities and prevalence of disease were inversely related to the rate of water flow at each sampling site. Results from laboratory rearings of field-collected larvae suggested that the impact of the virus on the midge populations was greater than that indicated by infection rates alone and that the virus may play an important role in population regulation. Studies with field collected egg masses suggested that the virus is introduced to the channels by transovum transmission.
