The paper presents the results of laboratory study of the modes of entomopathogenic densonucleasis virus transmission in the population of blood-sucking Culicidae mosquitoes. It was established that densovirus infection was horizontally transmitted through feeding of larvae on the bodies of desonucleasis-infected insects as well as contamination of the environment by infected larvae. Thus, the death rate in populations of various mosquito species attained 25.9-70.8%. Vertical transmission of the virus alters the ratio of sexes at the stage of imago; the survived females and males transmit infection to larvae. Surface sterilization of the ova doesn't prevent larvae infection, death rate among larvae attaining 7.8%.
