Item Uso de compostos repelentes produzidos por cães resistentes ao Rhipicephalus sanguineus sensu lato para o seu controle em cães susceptiveis(Universidade Federal de Goiás, 2018-02-21) Oliveira Filho, Jaires Gomes de; Pinto, Mara Cristina; http://lattes.cnpq.br/8221737491598415; Borges, Ligia Miranda Ferreira; http://lattes.cnpq.br/2591106734434348; Borges, Lígia Miranda Ferreira; Costa Junior, Livio Martins; Rodrigues, Viviane Zeringota; Monteiro, Caio Márcio de Oliveira; Faria, Adriana MarquesRhipicephalus sanguineus sensu lato, the "brown dog tick", preferentially parasite the domestic dog, in the latter can parasite others mammals species including humans. This tick demonstrates a hunting behavior by its host, being widely attracted by the bark and the CO2 among other signs related to the presence of its hosts. Despite being commonly found parasite on dogs, it is known that some breeds such as beagles are less parasitic than other breeds like English Cocker Spaniel which can present a parasitic load about up to 11.5 times higher than mongrel dogs. It is notable a capacity of ticks and other arthropods in their hosts in relation to desirable or undesirable characteristics that can perceive these by means of chemoreception of volatile compounds emanated by these hosts. This adaptive tool is called olfactory aposematism. Olfactory apostotism is capable of an ectoparasite in avoiding its hosts through a perception of a volatile chemical emanated by it that signals a negative adaptive response to the arthropod. Usually this response may be linked to immune factors, excessive grooming, inaccessibility or other factors. One of the big problems nowadays undoubtedly is the control of ticks and diseases that are transmitted to their hosts during the blood repast. One of the alternatives for control of parasitism in order to deter ticks from the search for their hosts is a use of compounds found in resistant hosts that are interpreted by these arthropods as non-hosts. These compounds demonstrate a more specific activity between arthropod parasites and their hosts, since they were selected during an adaptation between species involved in this parasite-host relationship forging bases of parasite selection by susceptible and resistant hosts.
