| The in vitro fungitoxic effect of three biofertilizers, E.M.-4, Multibion <FONT FACE=Symbol>Ô</FONT> and Supermagro used in organic agriculture and the neem oil (Azadirachta indica A. Juss) on the entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana was studied. These products were mixed in a medium where the two fungi were inoculated, and germination, vegetative growth and conidiogenesis were assessed. The biofertilizers Supermagro and E.M.- 4 showed to be less toxic for the two fungi whereas Multibion<FONT FACE=Symbol>Ô</FONT> caused major inhibition on M. anisopliae, with reductions in germination (-37.74%), colony diameter (-30.26%) and conidiogenesis (-42.62%). Neem oil promoted a larger negative effect on B.... |

| 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... |

| The objectives of this morphometric study of Culex (Culex) saltanensis Dyar, 1928 larvae were to observe the continuous growth of siphon and cephalic capsule length and width in each instar, and to propose a linear equation to differentiate instars according to the size of both structures. Larvae obtained in laboratory at 27 ± 1ºC, photoperiod 14L:12D were studied. Larvae of the forth instar were collected on the field and compared with same instar larvae reared in the laboratory. Egg size and pigmentation pattern, first instar continuous growth, and differentiation of larval stages measurements were studied. Egg pigmentation patterns and the shapes of raft eggs differentiated specimens of C. saltanensis from Culex (Culex) quinquefasciatus Say, 1823 found... |

| Fragmentos de mata na área urbana ou periurbana podem ser locais favoráveis a procriação de Culicidae. Esse trabalho teve como objetivo levantar as espécies de culicídeos que utilizam criadouros artificiais, suas coexistência e as flutuações populacionais em uma reserva de mata localizada em Londrina - PR. Realizou-se coletas quinzenais de outubro de 1995 a setembro de 1996 em pneus e internódios de bambu armadilha que foram instalados ao nível do solo e outros internódios instalados a 2 m de altura. Coletou-se 12.656 espécimes, pertencentes a cinco gêneros e 11 espécies. As espécies mais abundantes nos criadouros foram Limatus durham Theobald, 1901, Culex eduardoi Casal & Garcia, 1968, Aedes terrens (Walker, 1856), Culex quinquefasciatus Say, 1823... |

| 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... |
