[Cultivation of the mosquito Culex pipiens pipiens f. molestus (Diptera, Culicidae) without blood feeding].

Optimal photoperiod and temperature conditions for rearing of the mosquito Culex pipiens pipiens f. molestus without blood feeding (through autogenous eggs) were experimentally substantiated. This method may be used in order to obtain relatively small quantities of mosquitoes or for preservation of a laboratory colony. Optimal conditions of rearing are the short-day photoperiod (12 h of light per day) at 20 degrees C, when 87 % of the females produce autogenous eggs rafts consisting of 52 eggs on the average. It should be emphasized that larval food must be adequate and abundant, because the quality and quantity of it has a pronounced effect on the autogeny rate.
