title: Occurrence and prevalence of bot flies, Metacuterebra apicalis (Diptera: Cuterebridae), in rodents of cerrado from central Brazil.
abstract: The occurrence and prevalence of Metacuterebra apicalis (Diptera: Cuterebridae) in natural populations of Oryzomys subflavus, Bolomys lasiurus, and Thalpomys cerradensis (Rodentia: Muridae) from August 1990 to July 1992 in the cerrado, a common savanna-like vegetation type of central Brazil, are reported. An increase in bot infection in the 3 rodent species between October 1991 and July 1992 without correlation to precipitation was detected. The prevalence was lower than in neotropical forest formations. Mean intensity was 1.3 bots (range 1-2) for T. cerradensis and 1 bot for B. lasiurus and O. subflavus. This is the first record of T. cerradensis as host of bot flies.
