RESUMO

The Rondônia state has an area with rich arthropods diversity although the knowledge about the arboviruses transmition for these species is poor. The present work aimed to detect arboviruses through RT-PRC and RT-PCR Duplex in the diptera species collected in the region as well as their characterization through the sequence reaction. The RT-PRC and RT-PCR Duplex detected the Mayaro and Oropouche virus suspensions until 104 e 101 TCID50/mL respectively, although it was negative for the Dengue 2 virus in pools containing less than three infected mosquitoes. The endogenous control was detected in 66,8 % of samples and from pools containing from one to three mosquitoes the detection rate was approximately half from that obtained from pools with 11 to 15 mosquitoes. Oropouche virus was found in 0,66 % of pools and Cacipacore virus also in 0,66 % of pools. Oropouche virus was detected in Coquillettidia sp. and Deinocerites sp. while Cacipacoré virus was found in Anopheles sp. and Culex sp. The techniques allowed the detection of examined arboviruses in the pools collected from Rondonia.
