title: [Mineral fertilizers as regulators of the Culicidae population. I. Effect of nitrophos on Aedes larvae].
abstract: The effect of nitrophoska on the survival rate of Aedes sp. larvae (Ae. flavescens, Ae. cataphylla, Ae. vexans) was assessed for the first time under laboratory and in situ conditions. Threshold concentration of the water solution of nitrophoska (0.4-0.5% and 1%) producing a larvicidal effect on the larvae at the I-II and III-IV stages, subsequently, was established. Changes in water chemical regime due to the effect of 0.1-0.5%, 1-3-5% nitrophoska content, were observed in water bodies with developing Aedes larvae: pH shifted towards acid by 0.2-1.4; ammonium content increased significantly: from 3.1 to 800-1600 mg/l at 0.1 to 5%% nitrophoska contents, which may be the cause of a low number of Aedes in water-bodies of rural areas or their total absence.
