RT Journal Article SR Electronic T1 Flies Infected by Entomopathogenic Fungi in an Urban Fragment of Semideciduous Forest JF bioRxiv FD Cold Spring Harbor Laboratory SP 011742 DO 10.1101/011742 A1 Bruno Corrêa Barbosa A1 Tatiane Tagliatti Maciel A1 Fábio Prezoto YR 2014 UL http://biorxiv.org/content/early/2014/11/25/011742.abstract AB Entomopathogenic fungi parasitize a wide variety of hosts may be involved in regulating the populations of these arthropods helping maintain stability in tropical forest ecosystems. The genus Ophiocordyceps and Entomophthora contains several species of entomopathogenic fungi specialized to infect and kill their hosts due to development and the need for transmission by manipulating host behavior. Despite mounting research in the area, works with parasitized flies are scarce. This study aims to describe associations between the occurrence of entomopathogenic fungi and parasitic flies of the family Muscidae and behaviors presented by these flies parasitized in an urban fragment of semideciduous forest in southeastern Brazil. Were recorded two species of entomopathogenic fungi parasitizing flies collected for the first time in this locality, E. muscae and O. dipterigena. Different from Diptera parasitized by different fungi behaviors were observed. These new records of occurrence, along with data on their hosts, suggest that many species of this group have not yet registered. Therefore, more studies in tropical forests will certainly increase the knowledge about these interactions.
