[Mineral fertilizers as regulators of the population count of Culicidae. 2. The action of ammophos on Aedes dorsalis Mg larvae developing in mineralized reservoirs].

The effect of the fertilizer ammophos on Aedes dorsalis larvae developing in mineralized reservoirs of the "Staraia Russa" resort was tested in laboratory and field conditions. 100% death of Ae. dorsalis larvae, stage III-IV of development, and chrysalises was noted on day 2 in 0.5-1.0% ammophos water solution and on day 3 in 0.1% ammophos water solution. In natural mineralized reservoirs larvae and chrysalises died 10 days after treatment with ammophos at a dose of 350 g/m3. Introduction of ammophos into mineralized reservoirs increases drastically the content of chlorides destroying the molecules of dissolved oxygen and practically ousting it from the water, which is the cause of death of larvae and chrysalises.
