Abstract: | Simulium guianense Wise (Diptera: Simuliidae) is the main vector of the nematode Onchocerca volvulus (Leuckart) (Spirurida: Onchocercidae), which causes onchocerciasis in the Amazonian focus of the disease. We present the first report of the presence of S. guianense in the Parnaíba River basin, its oviposition behavior, and its number of instars. Immatures were found in high density on bedrock, on leaves of Podostemaceae and other aquatic plants, and on branches and leaves of riparian vegetation. Larvae and pupae were collected in 9 rivers: 8 in the state of Piauí and 1 in the state of Ceará. Six instars were determined for a population in Piauí. Oviposition behavior was of the dabbing type. Ants (Solenopsis sp.; Hymenoptera: Formicidae) preyed on larvae and pupae stranded when the river receded. |
