| The Igapó lake dam is located in an urban area in Londrina, Paraná, Brazil. A one year study of the Culicidae immature forms was conducted in this ecosystem. From a total of 962 collected larvae following genera were identified: Anopheles (59.36%), Culex (19.65%) Aedeomyia (19.23%) Aedes (1.50%), and Uranotaenia (0.10%). The 10 most abundant species were Anopheles strodei, Aedeomyia squamipennis, Culex (Melanoconium) spp., Culex mollis, Anopheles oswaldoi, Anopheles evansae, Culex coronator, Culex quinquefasciatus, Anopheles argyritarsis and Aedes terrens respectively. An. strodei prevailed with greater averages during July and September, showing a significant negative lineal correlation in relation to the rainfall. Ad. squamipennis showed a positive... |

| Culex (Culex) saltanensis Dyar, 1928 can become a problem in urban centers because they reproduce abundantly in ponds organically enriched. It is vector of the Plasmodium spp. and Crithidia ricadoi Sibajev et al. 1993. This research verifies the efficacy of Bacillus thuringiensis israelensis on C. saltanensis in two temperature situations, both in laboratory and field conditions. LC50 for C. saltanensis immatures fourth instar, was 0.154 ppm and the LC95 was 0.248 ppm an average temperature of 25.7ºC. When exposed at a constant temperature of 12±1ºC and a photoperiod of 14L:10D, had its susceptibity decreased in 1.50 times in reation to LC50, when compared to room temperature. B. thuringiensis israelensis is highly efficient in the control of this mosquito... |
