E-mail: vaniabit@ufrrj.br Ornithodoros mimon is an argasid tick common on Chiroptera in the Neotropical region, which also bites humans aggressively and it is often found in human habitations. Currently, there are no control methods for argasid ticks. However, previous works already reported the susceptibility of species of Argasidae to entomopathogenic fungi. Thus, the present study aimed to determine the in vitro pathogenecity of Metarhizium anisoplie s.l. on larvae and nymphs first instar of O. mimon. The biological parameter evaluated was the percentage of mortality of the larvae and nymphs. The results showed 80% larval mortality in the concentration of 107 conidia/mL and 91.4% for larvae subjected to a concentration of 108 conidia/mL. The engorged nymphs immersed in suspensions 107 conidia/ml were more susceptible to fungus that unfed nymphs. In the suspensions 108 conidia/ mL no difference was observed, because the average percentage mortality was above 95% for engorged and unfed nymphs. Based on the results obtained, we concluded that immature stages of O. mimon are susceptible to M. anisoplie s.l.

Atualmente, não foram estabelecidos métodos de controle. Porém, trabalhos prévios já demonstraram a susceptibilidade de outros argasí- deos a fungos entomopatogênicos. Dessa forma, o presente estudo teve como objetivo verificar a patogenicidade in vitro de Metarhizium anisopliae s.l. sobre larvas e ninfas de primeiro ínstar ingurgitadas e não ingurgitadas de O. mimon. O parâmetro avaliado foi o percentual de mortalidade das larvas e ninfas. Como resultados, observaram-se 80% de mortalidade do estágio larval na concentração de 107 conídios/mL e 91,4% para larvas submetidas à concentração de 108 conídios/mL. As ninfas ingurgitadas imersas na concentração 107 conídios/ mL foram mais susceptíveis ao fungo que as ninfas não ingurgitadas. Com relação à concentração 108 conídios/mL não foi observada diferença significativa, uma vez que se obteve um percentual médio de mortalidade acima de 95% tanto para as ninfas alimentadas como para as não alimentadas. Com base nos resultados obtidos, pode-se concluir que os estágios de O. mimon estudados são susceptíveis a M. anisopliae.Sociedade de Medicina Veterinária do Estado do Rio de Janeiro.2014-03-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpeer reviewedAvaliado pelos paresapplication/pdfhttps://rbmv.org/BJVM/article/view/679Brazilian Journal of Veterinary Medicine; Vol. 35 No. Supl.2 (2013); 43-47Revista Brasileira de Medicina Veterinária; v. 35 n.
