[The pilot project results of applications of the biolarvicide Bacillus sphaericus 2362 on mosquito breeding grounds of the town of Santa Cruz del Norte (La Habana Province)].
The effectiveness of the Bacillus sphaericus strain 2362 in liquid formulation, at a 10 ml/m2 dose, was tested in 157 breeding sites of Culex quinquefasciatus mosquitos, 2 breeding sites of Culex quinquefasciatus and Anopheles albimanus and 1 breeding site of Aedes taeniorhynchus, consisting of 1 river, 2 oxidation ponds, 1 pond, 4 dams, 2 microdams and 150 pits. The results reached with the application of 1800 1 of biolarvicide show its effectiveness. Within 24 hours of treatment, mortality rates were 100%, in a wide range of ecological conditions, its permanence up to 5 months in breeding sites without stream and innocuousness for other hydrobionts. DPGs in humans, having shown considerable reductions, confirm the advantages and potentialities of using this method under tropical conditions.
