Resumo
Numerous isolates of an oomycete ‘fungus’, Leptolegnia chapmanii, are reported from Brazil for the first
time. This aquatic pathogen was baited with Aedes aegypti sentinel larvae from stagnant, temporary bod ies of water in selected locations under secondary tropical forest in and near the central Brazilian city of
Goiânia and from more distant sites in the western and northern regions of the state of Goiás. Isolates
were identified based on their morphological and developmental characters, comparative sequence data
for the ITS and TEF loci, as well as their rapid activity against A. aegypti larvae. Taxonomic issues affecting
the application of the name L. chapmanii and its typification are rectified. This study contributes to a bet ter understanding of the presence and distribution of this oomycete in Brazil, its sequence-based identification, and of its potential as a biological agent against mosquito vectors.
