“…Specimens collected were frozen in liquid nitrogen for virus isolation. IdentiÞcation of mosquitoes followed Lane (1953), Bram (1967), Reinert (1975), Berlin and Belkin (1980), Sirivanakarn (1983), Pecor et al (1992), Judd (1996), Sallum and Forattini (1996), Harbach and Kitching (1998), and our own collections in the Laboratorio de Biologṍa de Vectores (LBV in Guimarães 1997).

Spatial Dispersion of Adult Mosquitoes (Diptera: Culicidae) in a Sylvatic Focus of Venezuelan Equine Encephalitis Virus

et al. 2001

We studied the spatial localization of mosquitoes in sylvatic focus of Venezuelan equine encephalitis virus in western Venezuela to identify mosquito species potentially involved in the hypothesized transport of viruses out of enzootic foci. The following criteria were used to identify species with potential for virus export: (1) common in the forest and surrounding area, (2) feeding on a wide range of vertebrates; (3) long dispersal capabilities, and (4) established vectorial competence for enzootic or epizootic VEE viruses. CDC traps baited with light/CO2 were operated for four and 12-h intervals to collect mosquitoes at four stations along two forest/open area transects from September to November 1997. We collected 60,444 mosquitoes belonging to 11 genera and 34 species. The most common species were Aedes serratus (Theobald), Ae. scapularis (Rondani), Ae. fulvus (Wiedmann), Culex nigripalus Theobald, Cx, (Culex) "sp", Cx. mollis Dyar & Knab, Cx. spissipes (Theobald), Cx. pedroi Sirivanakarn and Belkin, Psorophora ferox (Humboldt), Ps. albipes (Theobald), and Ps. cingulata (F.). Very few mosquitoes were captured during the (day in the open area outside the forest, suggesting that any virus export from the forest may occur at night. The following mosquitoes seemed to be mostly restricted to the forest habitat: Ae. serratus, Ps. ferox, Ps. albipes, sabethines, Cx. spissipes, Cx. pedroi, Cx. dunni Dyar, and Ae. fulvus. The main species implicated its potential virus export were Cx. nigripalpus, Ae. scapularis, and Mansonia titillans (Walker).

“…Pecor et al (1992) suggested that the Ocellatus Section (previously considered within the subgenus Microculex) did not belong to Melanoconion, and it remains without subgeneric assignment. Later, Sallum and Forattini (1996) made the Þrst revision for the Spissipes Section based on morphological characters of the adults male and female (including species identiÞcation keys). Most of these taxonomic studies have emphasized the importance of morphological characters in a traditional, noncladistic, or nonphylogenetic treatment.…”

Members of the New World mosquito subgenus Melanoconion of the genus Culex are important vectors of many alphaviruses including eastern and Venezuelan equine encephalitis viruses (VEEV). We investigated the phylogenetic relationships among nine putative species of the Vomerifer and Pedroi Groups of the Neotropical Spissipes Section by sequencing the internal transcribed spacer 2 (ITS-2) region of ribosomal DNA and using phylogenetic analyses. Results demonstrated that, within the Spissipes Section, the Vomerifer and Pedroi Groups are monophyletic sister groups. The clade comprised by Culex adamesi and Culex ribeirensis showed a sister group relationship to the group consisting of Culex pedroi sequences. The monophyly of the Vomerifer Group corroborated previous suggestions that it is a natural group. However, our topology showed that there are two well-supported, divergent groups within a major clade consisting of Cx. pedroi sequences, suggesting the possibility of a cryptic Cx. pedroi-like species. This finding could have important epidemiological implications for VEEV transmission in Central and South America.

“…12 In each village, 10 households were also selected, where 10 Centers for Disease Control and Prevention light traps baited with octanol as an attractant and four encephalitis vector survey (CO 2 ) mosquito traps (BioQuip Products, Rancho Dominguez, CA) were placed. The following day, mosquitoes were collected in the field, transported to the base camp where they were anesthetized, identified to the genus level using taxonomic keys 13 and then were placed in cryovials for storage in liquid nitrogen.

Abstract. Viruses in the genus Flavivirus (family Flaviviridae) include many arthropod-borne viruses of public health and veterinary importance. However, during the past two decades an explosion of novel insect-specific flaviviruses (ISFs), some closely related to vertebrate pathogens, have been discovered. Although many flavivirus pathogens of vertebrates have been isolated from naturally infected mosquitoes in Panama, ISFs have not previously been reported from the country. This report describes the isolation and characterization of a novel ISF, tentatively named Mercadeo virus (MECDV), obtained from Culex spp. mosquitoes collected in Panama. Two MECDV isolates were sequenced and cluster phylogenetically with cell-fusing agent virus (CFAV) and Nakiwogo virus (NAKV) to form a distinct lineage within the insect-specific group of flaviviruses.
