Piperonyl butoxide. This study was conducted to evaluate the efficacy of a new topical ectoparasiticidal spot-on containing 4.95% dinotefuran (w/w), 36.08% permethrin (w/w) and 0.44% pyriproxyfen (w/w) (Vectra 3D, Ceva, Libourne, France) against Portuguese strain of Phlebotomus perniciosus and a French strain of Ctenocephalides canis in dogs. The new PMC design is here! Fourie JJ, Liebenberg JE, Horak IG, et al. Collected fleas were counted, recorded and discarded. At each challenge point, there was a significant statistical difference (p<0.05) in the number of dead P. perniciosus after 1 and 24h of exposure between the treatment and control group. The combination of dinotefuran and pyriproxyfen has been tested on cats against C. felis (Murphy et al. Interestingly, the new combination tested here ensured a better and longer insecticidal effect than permethrin in association with imidacloprid (Mir et al. C. canis has a worldwide distribution. Afoxolaner (NexGard; nexgardfordogs.com), fluralaner (Bravecto; us.bravecto.com), and sarolaner (Simparica; simparica.com) are all available as flavored chewable oral tablets labeled for dogs only; fluralaner is also available in a topical formulation for both cats and dogs.2022 Afoxolaner and sarolaner are given monthly, whereas fluralaner is given every 3 months.2022 Because these tablets are flavored with food-based ingredients (soy or pork), they are not suitable for administration during food allergy elimination diet trials, and they may or may not be tolerated by food-allergic individuals. Killick-Kendrick R, Killick-Kendrick M, Focheux C, Dereure J, Puech MP, Cadiergues MC. Mean counts (SD) of fleas combed 48h after each infestation are represented in Fig. At each challenge point post-treatment (day 1, day 7, day 14, day 21 and day 28), the difference of engorgement status of P. perniciosus females between treated and controlled group was significant (p<0.05). They are also efficacious against many species of ticks, including Ixodes scapularis, Dermacentor variabilis, Rhipicephalus sanguineus, and Amblyomma americanum.2022 However, fluralaner must be given every 2 months for maximal efficacy against A americanum.20 Sarolaner also has efficacy against A maculatum.22, All of the agents appear to have very good efficacy against canine demodicosis.2325 Evidence shows that they are also effective against Sarcoptes, although whether this is reliable enough to permit diagnostic therapy remains to be seen.2628 Sarolaner has also been demonstrated to be efficacious against Otodectes species.25. Because the agents are very similar in many respects, they will be discussed together. Corbel V, Duchon S, Zaim M, Hougard JM. This article provides an overview of some of the clinically relevant features of currently available flea control agents (Table 1). Guidelines for prevention of leishmaniasis in dogs. Pyrethrin is derived from the chrysanthemum plant.2 It is generally very safe when applied properly, even in young cats.1 Pyrethrin has a very quick knock-down effect but minimal residual activity. Six RH, Becskei C, Mazaleski MM, et al. Stanneck D, Ebbinghaus-Kintscher U, Schoenhense E, Kruedewagen EM, Turberg A, Leisewitz A, Jiritschka W, Krieger KJ. The synergy of action can result to this specific combination as it was demonstrated for imidacloprid and flumethrin against ticks and C. felis and required more investigations (Stanneck et al. (2011) showed that this combination was efficient in in-home investigations in Florida (USA) for at least 1month in the control of flea infestations and re-infestations. She received her veterinary degree from Louisiana State University and completed residency training at North Carolina State University. Compared with pyrethrin, these products have a slightly slower onset of action but significantly better residual and repellent effects. National Library of Medicine Efficacy of fluralaner administered either orally or topically for the treatment of naturally acquired. Topical insecticide treatments to protect dogs from sandfly vectors of leishmaniasis. and transmitted securely. Twelve beagle dogs were exposed for 1h to 100 P. perniciosus on day 6 for allocation in two groups. Analyses were performed with Systat 9 software. This product has a rapid onset of action.10,11 It primarily targets adult fleas, and it is often combined with an insect growth regulator to provide efficacy against immature flea stages.1 Imidacloprid is available as a spot-on product, either by itself or in combination with permethrin (K9 Advantix), flumethrin (Seresto collar; seresto.com), or moxidectin (Advantage Multi; bayerdvm.com). Madison, NJ: Merck Animal Health; 2016. Efficacy of an imidacloprid/flumethrin collar against fleas, ticks and tick-borne pathogens in dogs. The percentages of engorged females before treatment were 73.40 and 74.28% for both the treated and the control groups, respectively. They were then introduced into blocks of two animals; each, and within each block, dogs were randomly allocated in two groups: treatment or control group. These are the oldest flea control products currently in common use. Protection of dogs from bites of phlebotomine sandflies by deltamethrin collars for control of canine leishmaniasis. 2004 and Reithinger et al. For dogs weighing more than 10.1kg, a 3.6-ml pipette was applied to three areas: between the shoulder blades, in the middle of the dorsal midline and at the base of the tail. 2012). Then, all remaining sandflies were discarded. Evaluation of indoxacarb and fipronil (s)-methoprene topical spot-on formulations to control flea populations in naturally infested dogs and cats in private residences in Tampa FL. 2012). Before Solano-Gallego L, Mir G, Koutinas A, Cardoso L, Pennisi MG, Ferrer L, Bourdeau P, Oliva G, Baneth G. LeishVet guidelines for the practical management of canine leishmaniosis. Besides its direct pathogenic role, this flea has been proven to be a vector of various pathogens such as Rickettsia felis, Dipylidium caninum and Acanthocheilonema reconditum (Pantchev et al. Pyrethroids are often combined with other agents to take advantage of the pyrethroids repellent effects and efficacy against ticks. European Medicines Agency (2012) Testing and evaluation of the efficacy of antiparasitic substances for the treatment and prevention of tick and flea infestations in dogs and cats. Moreno J, Vouldoukis I, Martin V, McGahie D, Cuisinier AM, Gueguen S. Use of a LiESP/QA-21 vaccine (CaniLeish) stimulates an appropriate Th1-dominated cell-mediated immune response in dogs. All control dogs maintained an adequate number of engorged females throughout the study. above 50% of engorged females per dog, Fig. It is readily removed by water exposure. Bass C, Schroeder I, Turberg A, et al. Resistance to pyrethrins and pyrethroids has been reported in both colonized flea strains and wild-caught fleas.6,7 Resistance may be associated with mutations in a gene coding for neural sodium channels.8 These mutations, which are commonly referred to as kdr (knockdown resistance) or super kdr mutations, are widely distributed throughout flea colonies and in field-collected fleas.9 As a result, the effectiveness of this class of compounds may be reduced in some areas, especially when they are not combined with other therapeutic agents. Phone: +33-5-61193873, Fax: +33-5-61193971. The study was conducted in the Ecole Nationale Vtrinaire de Toulouse (ENVT) and was a single-centre, randomized, blinded, controlled efficacy study on two groups of six dogs each. Kalamazoo, MI: Zoetis, Inc; 2015. Water was available ad libitum through automatic lickers. Dogs were treated on day 0 with a dinotefuran, permethrin and pyriproxyfen combination spot-on and then weekly infested with 100 C. canis. Both pyrethrin and pyrethroids work by disrupting insect nerve sodium channels.1 They are active against adult fleas but have no efficacy against immature stages. Reithinger R, Teodora U, Davies CR. Mean number of engorged Phlebotomus perniciosus females after 1h exposure to control and treated dogs. The adulticidal effect on C. canis remained above 99% throughout the study period. Neural network-based QSAR and insecticide discovery: spinetoram. We assume that the repellent and insecticidal effects on adults observed here were due to the combination of permethrin and dinotefuran. Examples of this class include permethrin and cyphenothrin. It is labeled for once-monthly administration. (2012) against Aedes aegypti the day following the treatment without explanation. Maroli M, Gradoni L, Oliva G, Castagnaro M, Crotti A, Lubas G, Paltrinieri S, Roura X, Zini E, Zatelli A. 2004). Vo DT, Hsu WH, Abu-Basha EA, Martin RJ. For each time point after exposure, the anti-feeding rate was evaluated for each group as described below and compared to the control group: Then, the anti-feeding effect (expressed in percentage) was determined: For each time point after exposure, the mortality rate was evaluated for each group as described below and compared to the control group: Then, the mortality effect (expressed in percentage) was determined: The data collected were the number of fleas found alive on the dogs after combing. 2 document of the European Medicines Agency (2012). Susceptibility of adult cat fleas (Siphonaptera: Pulicidae) to insecticides and status of insecticide resistance mutations at the Rdl and knockdown resistance loci. For all treated animals, the formulation was applied accordingly to manufacturers instructions by parting the hair and applying it directly to the skin: for dogs weighing less than 10.0kg, the 1.6-ml pipette was used from which one half of the dose was applied between the shoulder blades and the other at the base of the tail. 3h30min after the end of exposure to sandflies), they were infested with 1002 C. canis. In the present study, the efficacy of a spot-on combining dinotefuran, permethrin and pyriproxyfen was experimentally assessed on P. perniciosus and C. canis. 2012). Franc M, Bouhsira E. Efficacy of a combination of a fipronil-(S)-methoprene spot-on formulation and a deltamethrin impregnated collar in controlling fleas and sandflies on dogs. Twelve beagle dogs (seven females and five males with an age range of 5 to 10years and weighing between 9 and 13.11kg) were enrolled in the study. Insect nicotinic acetylcholine receptor agonists as flea adulticides in small animals. This agent is an avermectin, similar to ivermectin.1,29 It activates insect glutamate-gated chloride channels, which causes paralysis and eventual death of the fleas. government site. The sandfly strain was obtained from Lisboa, Portugal and was maintained at ENVT under laboratory conditions since 2003. Received 2013 Jul 4; Accepted 2013 Jul 31. Bethesda, MD 20894, Web Policies The development of insecticide resistance is a continuing threat. Molina R, Mir G, Glvez R, Nieto J, Descalzo MA. will also be available for a limited time. Horak IG, Fourie JJ, Stanneck D. Efficacy of slow-release collar formulations of imidacloprid/flumethrin and deltamethrin and of spot-on formulations of fipronil/(s)-methoprene, dinotefuran/pyriproxyfen/permethrin and (s)-methoprene/amitraz/fipronil against. However, the anti-feeding effect obtained with permethrin alone was not as persistent as the combination of dinotefuran and permethrin tested here. They were fed a commercial dry dog food, ration calculated so as to maintain the animal in a healthy physical state. Two classes of insect growth/development regulators have been registered for use as flea control products: juvenile hormone analogs (methoprene, pyriproxyfen) and chitin synthesis inhibitors (lufenuron).1 These agents have no adulticidal effects but prevent the development or maturation of immature flea stages. This agent is primarily active against adult fleas.1 It is available in a spot-on formulation in combination with an insect growth regulator either with (Vectra 3D) or without (Vectra) permethrin. The major side effect in both species is vomiting, which can be treatment limiting in some individuals.16 Spinosad should be administered with caution (or avoided entirely) in dogs with preexisting seizure disorders because seizures have been associated with administration of this drug in these dogs.16 However, this effect has not been reported in cats. Moreover, dinotefuran has been suggested to be used in areas of resistant mosquitoes against common insecticides (Corbel et al. 2001), a permethrinimidacloprid spot-on (Mencke et al. They were combed 48h after infestation. However, pyrethrins and many synergists may be highly toxic to other pet species, such as fish and amphibians.2,3.
