[The effect of density and temperature on the larval populations of the malaria vector Anopheles sacharovi]. / Vliianie plotnosti i temperatury na lichinochnye populiatsii perenoschika maliarii Anopheles sacharovi.

9 variants of cultivation of larvae at different population density (3.3-842.1 sp. per dm2), have been tested at 7 different temperatures (from 21 +/- 1 to 32 +/- 1 degrees C) each. Quantitative characteristics of the effect of 2 factors on the survival of larvae and duration of larval development are presented. Sexual structure of population is practically unchanged at density of the larvae (6.6-26.3 sp. per dm2), but in rarefied or extremely dense populations the males were prevailing. 233-290 pupae may be obtained from 1 m2 of medium per day in the first three days of pupation under optimal conditions of cultivation (13 larvae per dm2 at 28-30 degrees C). Increased sensitivity of An. sacharovi larvae to over-population allows to draw a conclusion of the higher cost of mass production of this mosquito species compared to other malarial vectors.
