[Experience in using traps for collecting the eggs deposited by the urban mosquito (Culex pipiens)].

Egg-traps detect Culex pipiens when other methods (mosquito recording in the premises, registration of its attacks and, interview with people) yield negative results. This allows one to assess the rates of its water reservoir occupation and breeding with regard to less time spent and greater hygienic efforts. In the place under study, C.pipiens females make their first cycle autogenously in the immediate vicinity of a breeding place and fly away only after termination of the first egg-laying.
