“…Cx. theobaldi was once captured on a horse (Forattini and Sallum 1989), and its tendency to blood feed on reptiles was unknown to date. This Melanoconion species is chießy active at night (Jones et al 2004), and its immature stages have been found both in temporary and permanently ßooded areas of different extents and under different levels of shading.…”

Mosquitoes that feed on crocodilians are poorly known, despite the potential role of these exothermic animals as reservoirs of arboviruses. In this article, we assessed the frequency, abundance, and temporal variation of caiman-biting mosquitoes as well as searched for the natural vectors of the blood parasite of caimans, Hepatozoon caimani, in the Pantanal area of central-western Brazil from captures conducted bimonthly from September 2006 to September 2007 and in February 2008. A total of 5,272 mosquitoes belonging to 10 species of five genera was caught on caimans. The most abundant species were Culex (Melanoconion) theobaldi, Mansonia (Mansonia) titillans, Mansonia (Man.) humeralis, and Mansonia (Man.) amazonensis, which together accounted for 80% of all sampled individuals. Other blood-feeding Melanoconion species were also found quite frequently on caimans, including Culex clarki, Culex idottus, and Culex bastagarius. Oocysts of H. caimani were exclusively detected in Culex species, mainly in individuals of the subgenus Melanoconion, and we accomplished experimental transmission from naturally infected mosquitoes to uninfected Caiman yacare. The highest infection rates were observed in Cx. theobaldi (0.55%), which is therefore indicated as the primary vector of H. caimani. In addition, because the above mentioned Melanoconion and Mansonia species are abundant, widespread, and have a broad set of hosts, including crocodilians, they may be suggested as potential vectors of arboviruses, such as West Nile virus, in the Southern Cone in South America.

Collections of mosquitoes were conducted for the surveillance of species of medical importance in the state of Quintana Roo, Mexico, in June of 2017. Species collected included Psorophora (Psorophora) cilipes and Culex (Melanoconion) theobaldi, both new records for the state. Psorophora cilipes was previously recorded in Mexico State and Cx. theobaldi in Chiapas State. With the addition of these species, the mosquito fauna of Quintana Roo State now includes 81 species. Quintana Roo and Tamaulipas State with 82 species are the most mosquito-rich states in Mexico, based on currently available records. The specimens collected in this study were deposited in the Culicidae collection of the Universidad Autónoma Agraria Antonio Narro Unidad Laguna.
