Ciclo biológico de Ctenocephalides felis felis (Bouché, 1835) (Siphonaptera, Pulicidae) a partir de diferentes dietas artificiais

RESUMO

In this study 12 different diets to cat flea larvae, Ctenocephalides felis felis (Bouché, 1835), were tested in the following formulations 1 part of wheat germ and 1 part of bovine, equine or ovine dried blood; 20 parts of dog chow, 4 parts of bovine, equine or ovine dried blood and 1 part of brewers yeast; 20 parts of dog chow, 3 parts of bovine, equine or ovine dried blood and 2 parts of brewers yeast; and 100 parts of bovine, equine or ovine dried blood, 15 parts of dog chow and 5 parts of brewers yeast. All diets were mixed 15 with sand. Just as control flea feces and sand were used in the ratio of 120. To each formulations were made 6 repetitions then were placed 2 g of the tested diet per assay tube and 20 eggs from the cat flea laboratory colony at the Departament of Animal Parasitology of the Veterinary Institute at Federal Rural University of Rio de Janeiro. Diets containing bovine and equine dried blood and wheat germ in the ratio of 11 showed high percentage of emerged adults, respectively 7 3,3% and 71,6%, when compared with the diets with dog chow and brewers yeast in the ratio of 2041 (65,8% and 57,5%) and 2032 (62,5% and 64,1%). Diets containing ovine blood showed a percentage of emerged adults around 50%.
