Ciclo biológico de Ctenocephalides felis felis (Bouché, 1835) (Siphonaptera, Pulicidae) a partir de diferentes dietas artificiais
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 brewer’s yeast; 20 parts of dog chow, 3 parts of bovine, equine or ovine dried blood and 2 parts of brewer’s yeast; and 100 parts of bovine, equine or ovine dried blood, 15 parts of dog chow and 5 parts of brewer’s yeast. All diets were mixed 1:5 with sand. Just as control flea feces and sand were used in the ratio of 1:20. 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 1:1 showed high percentage of emerged adults, respectively 7 3,3% and 71,6%, when compared with the diets with dog chow and brewer’s yeast in the ratio of 20:4:1 (65,8% and 57,5%) and 20:3:2 (62,5% and 64,1%). Diets containing ovine blood showed a percentage of emerged adults around 50%.
