ABSTRACT:
Biological
control, as alternative of confrontation of vector organisms, is becoming more
necessary every day due to the development of
resistance to insecticides. The objective of this
investigation
consisted in identifying the species of copepods and fishes that inhabit in the
fluvial ecosystems of
Sancti Spíritus province, with emphasis in the species with best bio regulators qualities about larval populations
of culicids. The investigation comprised the period 2000-2011. In the case of
copepods, they were reported
new records of the genus Mesocyclops from Cuba, where the species identified possess good bio regulators qualities;
in especial, about the first immature phase or stage of mosquitoes. In relation
to fluvial fishes, six samplings were carried out in 90 fluvial ecosystems of
eight municipalities from the province, where 15 species of fishes grouped in
12 geneses and six families were identified. High bio regulator capacity of the
species Gambusia punctata and Gambusia puncticulata was demonstrated, which gave evidence of
changes in the populations of the provincial current fluvial ictiofauna.
