| Sumario: |
The identification of mosquito vector species present at arboviral enzootic transmission foci
is important to understand transmission eco-epidemiology and to propose and implement
prevention and control strategies that reduce vector-borne equine encephalitis transmis-
sion. The goal of this study was to identify mosquito species potentially involved in the trans-
mission of enzootic equine encephalitis, in relation to their abundance and diversity at three
endemic regions in the Repu ́blica de Panama ́. We sampled adult mosquitoes during the dry
and rainy season of Panama ́. We employed CDC light traps with octanol, EV traps with CO2
and Trinidad 17 traps baited with live hamsters. Traps were deployed in the peridomicile
and extradomicile of houses from 18:00 to 6:00 h. We estimated the abundance and diver-
sity of sampled species. We collected a total of 4868 mosquitoes, belonging to 45 species
and 11 genera, over 216 sampling nights. Culex (Melanoconion) pedroi, a major Venezue-
lan equine encephalitis vector was relatively rare (< 2.0% of all sampled mosquitoes). We
also found Cx. (Mel) adamesi, Cx. (Mel) crybda, Cx. (Mel) ocossa, Cx. (Mel) spissipes, Cx.
(Mel) taeniopus, Cx. (Mel) vomerifer, Aedes scapularis, Ae. angustivittatus, Coquillettidia
venezuelensis, Cx. nigripalpus, Cx. declarator, Mansonia titillans, M. pseudotitillans and
Psorophora ferox all species known to be vectorially competent for the transmission of arbo-
viruses. Abundance and diversity of mosquitoes in the sampled locations was high, when
compared with similar surveys in temperate areas. Information from previous reports about
vectorial competence / capacity of the sampled mosquito species suggest that sampled
locations have all the elements to support enzootic outbreaks of Venezuelan and Eastern
equine encephalitides. |
