[Appearance of variants in the artificial infection of larvae of the blood-sucking mosquito, Culex modestus, infested with the entomopathogenic fungus, Coelomomyces iliensis].

For infection of water bodies there were used ground and non-ground, undried (fresh material) and dried (within a year) Culex modestus larvae infected with Coelomomyces iliensis, substratum (bottom mud 1 to 3 cm thick) and biomass (aggregation of live and vegetable organisms taken from natural water bodies with infected larvae. During laboratory tests the mortality of larvae infected with ground undried individuals was from 40 to 88%; the introduction of biomass caused 37 to 65% mortality and the infection with substratum--36% mortality.
