dc.description.abstractA pulga do gato, conhecida como Ctenocephalides felis felis, representa o principal ectoparasito encontrado em cães e gatos domésticos em todo o mundo. Esses insetos desempenham um papel fundamental como vetores de importantes agentes patogênicos, e a saliva deles pode desencadear dermatite alérgica por picada de pulga. Os reguladores de crescimento de insetos, são amplamente empregados em estratégias de controle e suas combinações demonstram ser promissoras para o desenvolvimento de novas formulações. O objetivo do trabalho foi avaliar a atividade do diflubenzuron e triflumuron, estimar asconcentrações letais (CL) e avaliar a associação destes dois reguladores para as formas imaturas de C. felis felis. No presente estudo foram testadas in vitro, larvas de C. felis felis de primeiro ínstar em dois gramas de dieta larval impregnada com diflubenzuron e triflumuron em diferentes concentrações de para ambos os compostos. Após a impregnação, avaliou-se tanto a evolução do ciclo e como a emergência dos adultos desafiados no dia 28 após a impregnação. Observou-se uma atividade reguladora de 97,9% na concentração 5 ppm (5 μg/g) de diflubenzuron em larvas de 1o instar e de 100 % na concentração 10 ppm (10 μg/g) de triflumuron. As concentrações letais 50 para larvas foram de 0,370 ppm (0,370 μg/g) para diflubenzuron e de 3,45 ppm (3,45 μg/g) para triflumuron. Com bases nesses resultados, pôde se afirmar que essas benzoilfenilureias obtiveram atividade sobre as larvas de C. felis felis interferindo em seu ciclo de desenvolvimento, apresentando um efeito inibidor de emergência de adultos. Contudo, esses reguladores de crescimento não apresentaram o efeito sinérgico no controle de C. felis felis.pt_BR

dc.description.abstractOtherThe cat flea, known as Ctenocephalides felis felis, is the main ectoparasite found on domestic dogs and cats worldwide. These insects play a key role as vectors for important pathogens, and their saliva can trigger flea-bite allergic dermatitis. Insect growth regulators are widely used in control strategies and their combinations show promise for the development of new formulations. The aim of this study was to evaluate the activity of diflubenzuron and triflumuron, to calculate the estimated lethal concentrations (LC) and to evaluate the combination of these two regulators for immature forms of C. felis felis. In this study, first- stage C. felis felis larvae were tested in vitro on two grams of larval diet impregnated with diflubenzuron and triflumuron. After impregnation, the cycle was evaluated and the emergence of the challenged adults on day 28.A regulatory activity of 97.9% was observed at a concentration of 5 ppm (5 μg/g) of diflubenzuron in 1st instar larvae and 100 % at a concentration of 10 ppm (10 μg/g) of triflumuron .The lethal concentrations 50 for 1st instar larvae were 0.370 ppm (0.370 μg/g) for diflubenzuron and 3.45 ppm (3.45 μg/g) for Triflumuron .Based on these results, it can be said that these benzoylphenylureas were active on C. felis felis larvae, interfering in their development cycle and inhibiting the emergence of adults. However, these growth regulators did not have a synergistic effect on the control of C. felis felis.en
