title: [Residual activity in vitro of treated dog's hair coat with dinotefuran on larvae and adults of Ctenocephalides felis felis (Bouché, 1835) (Siphonaptera: Pulicidae)].
abstract: The aim of this study was to evaluate the residual activity of treated dog's hair coat with dinotefuran on larvae and adults of Ctenocephalides felis felis. Three female Beagle dogs were used. One female dog was treated with 0.834% dinotefuran spray, the second was treated with 30% dinotefuran strip-on and the third was not treated. Some areas of dog's hair were clipped on days 2, 9, 16, 23, 30, 37 and 44 after treatment. For the evaluation of adulticidal and larvicidal activities, flea adults and larvae from the laboratory colony were used. Six repetitions were used with 10 samples of each flea stage per day, placed in assay tubes. In each repetition we added 0.02 g of treated or untreated dog's hair and larval diet for the immature stage. Flea adult assay was evaluated with 24 hours and the flea larvae 20 days after treatment. The residue on hair coat of both treated dogs showed efficacy on the flea larvae control for 44 days. Regarding the flea adults control the spray and strip-on formulations showed efficacy until days 16 and 23, respectively.
