Resumo: Boophilus microplus can cause several cattle pathology and thus economic losses. Moreover, this tick species is able to develop resistance to acaricides. The biological control is a great promise to control cattle ticks populations. The aim of the present study was to contribute to the development of a new complementary method to control B. microplus. Therefore, it has been evaluated the compatibility between deltamethrin and the entomopathogenic fungi Beauveria bassiana and Metarhizium anisopliae toward B. microplus tick in a stable test. It was used a tick strain resistant to pyrethroid and calves were artificially infested. A total of 8 calves were held in individual housing and infested with B. microplus larvae every other day for 25 days. After that, 4 treatments were realized with 2 calves per group. The control group was tested receiving just water; the second group was tested receiving M. anisopliae in a 108 conidia ml-1 suspension; the third one was tested receiving a 25 ppm deltamethrin solution; and the forth group was tested receiving a solution containing a 108 conidia ml-1 M. anisopliae suspension associated with a 25 ppm deltamethrin solution. The mortality rate was 32.57% in the second group, 38.58% in the third group, and 30.92% in the forth one. The main changes in ticks biology were a decreased nutritional rate until the forth day after treatment. The deltamethrin group was an exception with a decreased rate until the second day after treatment. The production of eggs rate was also decreased until the second day after treatment in all 3 tested groups. Therefore, the association between deltamethrin and B. bassiana and M. anisopliae could be used for B. microplus integrated management. Based on compatibility between acaricide and biological agents, it could be possible the use of both simultaneously on infested cattle. Thus, it is possible to control ticks resistant to deltamethrin if an association with entomogenous fungi such as Beauveria bassiana and Metarhizium anisopliae is established. The best performance of these fungi, associated or not with deltamethrin, was observed for a short period after treatment.

As pesquisas realizadas utilizando controle alternativo de B. microplus t?m apontado que os fungos que naturalmente promovem a infec??o e at? a morte de diversas esp?cies e est?gios de vida de carrapatos s?o, promissores candidatos a esse papel de agente de controle microbiano. Com o objetivo de fornecer subs?dios que complementar?o o controle desta parasitose, avaliou-se in vivo a compatibilidade entre a deltametrina e os fungos Beauveria bassiana e Metarhizium anisopliae sobre cepa resistente de B. microplus a deltametrina, atrav?s do teste de est?bulo, com bovinos infestados artificialmente. Foram utilizados oito bezerros, para cada bioensaio, alojados individualmente, infestados em dias alternados com larvas de B. microplus por um per?odo de 25 dias. Ao t?rmino da infesta??o, foram realizados quatro tratamentos com dois animais por grupo. O grupo controle recebeu somente ?gua; o grupo tratado com fungo recebeu suspens?o conidial na concentra??o de 108 con?dios/ml; o grupo tratado com deltametrina recebeu solu??o na concentra??o de 25 ppm e o grupo tratado com associa??o recebeu suspens?o do fungo na concentra??o de 108 con?dios/ml com deltametrina a 25 ppm. Os resultados foram obtidos atrav?s da contagem di?ria dos carrapatos desprendidos do corpo dos animais, al?m da avalia??o dos par?metros biol?gicos das f?meas, as quais foram incubadas em c?mara climatizada. Realizaram-se dois bioensaios, sendo o primeiro com o fungo Metarhizium anisopliae, onde os percentuais m?dios de mortalidade foram: 32,57% para este fungo, 38,58 % para deltametrina e 30,92% para associa??o entre ambos. No segundo bioensaio foi utilizado o fungo Beauveria bassiana, onde os percentuais m?dios de mortalidade foram: 26,06% para este fungo, 64,30% para deltametrina e 70,64% para associa??o entre ambos. Quanto aos par?metros biol?gicos, as principais altera??es em ambos bioensaios foram a redu??o do ?ndice nutricional, principalmente at? o quarto dia ap?s tratamento, com exce??o da deltametrina que reduziu at? o segundo dia ap?s o tratamento. O ?ndice de produ??o de ovos s? foi reduzido at? o segundo dia ap?s tratamento para todos os grupos do primeiro bioensaio e somente no quarto dia ap?s o tratamento para o B. bassiana. Sendo assim, a associa??o entre deltametrina e os fungos testados pode ser utilizada como ferramenta para o manejo integrado de B. microplus, demonstrando compatibilidade in vivo entre acaricida qu?mico e bio l?gico, sendo poss?vel sua utiliza??o, simult?nea sobre bovinos infestados com B. microplus. O melhor desempenho desses fungos, associados ou n?o, foi observado em um per?odo curto ap?s o tratamento.Made available in DSpace on 2016-04-28T20:16:20Z (GMT).
