“…In contrast, data from our febrile surveillance study suggest that the number of IQT9924 virus-infected patients peak from December to April indicating a possible overlap with the biting activities of C. insinuatus [30]. Felippe-Bauer et al [41] recently identified two new morphological species in the C. paraensis complex from the Department of Amazonas and Loreto, Peru. Thus, future studies should investigate the role of this midge in ORO and IQT9924 virus transmission.…”

Iquitos Virus: A Novel Reassortant Orthobunyavirus Associated with Human Illness in Peru

et al. 2011

Oropouche (ORO) virus, a member of the Simbu serogroup, is one of the few human pathogens in the Orthobunyavirus genus in the family Bunyaviridae. Genetic analyses of ORO-like strains from Iquitos, Peru, identified a novel reassortant containing the S and L segments of ORO virus and the M segment of a novel Simbu serogroup virus. This new pathogen, which we named Iquitos (IQT) virus, was first isolated during 1999 from a febrile patient in Iquitos, an Amazonian city in Peru. Subsequently, the virus was identified as the cause of outbreaks of “Oropouche fever” during 2005 and 2006 in Iquitos. In addition to the identification of 17 isolates of IQT virus between 1999 and 2006, surveys for neutralizing antibody among Iquitos residents revealed prevalence rates of 14.9% for ORO virus and 15.4% for IQT virus. Limited studies indicate that prior infection with ORO virus does not seem to protect against disease caused with the IQT virus infection. Identification of a new Orthobunyavirus human pathogen in the Amazon region of Peru highlights the need for strengthening surveillance activities and laboratory capabilities, and investigating the emergence of new pathogens in tropical regions of South America.

“…It is found throughout the Americas, from Argentina to the United States (Felippe-Bauer et al 2003), and it is the most studied species of the New World Culicoides. High incidences of ORO virus have been reported in urban and wild areas in several states of the Brazilian Amazon.…”

Some species of biting midges are vectors of pathogens that cause disease in vertebrates, including humans. The aim of this study was to survey the biting midge fauna in Tefé, Amazonas, Brazil. Culicoides were collected using HP light traps during January, February, and April 2013. Midges collected included one species from the genus Lectoconops that bites humans. A total of 248 Culicoides individuals were collected, representing 19 species from two subgenera (Haematomyidium and Hoffmania) and four informal species groups (carpenteri, leoni, fluvialis, and reticulatus). Twelve individuals of L. brasiliensis were also collected, and this is the first record of L. brasiliensis in Amazonas. Three species of Culicoides were also recorded for the first time in Amazonas, including Culicoides aitkeni, C. glabellus and C. ocumarensis. The most abundant species were C. hylas (81 individuals), and C. foxi (27). The Culicoides fauna in Tefé is diverse, and proven vectors such as C. paraensis and C. insignis were found.

“…Revisions in this subgenus for the Neotropics were made for the debilipalpis species group (Vitale et al 1981) and for the paraensis species group (Wirth & Felippe-Bauer 1989, Felippe-Bauer et al 2003. According to Borkent and Spinelli (2007), 36 neotropical species are recognized in this subgenus.…”

During entomological surveys in the municipalities of São Geraldo do Araguaia and Juruti, Pará (PA), Brazil, female specimens of Culicoides belonging to two undescribed species of the subgenus Haematomyidium Goeldi were collected.The purpose of this paper is to describe and illustrate these new species from Northern Brazil and make a discussion with related species of the subgenus Haematomyidium. Revisions in this subgenus for the Neotropics were made for the debilipalpis species group (Vitale et al. 1981) and for the paraensis species group (Wirth & Felippe-Bauer 1989, Felippe-Bauer et al. 2003. According to Borkent and Spinelli (2007), 36 neotropical species are recognized in this subgenus.Recently, Felippe-Bauer and Spinelli (2009) considered Culicoides bachmanni Spinelli as a junior synonym of Culicoides horticola Lutz. With this taxonomy update and the addition of the two new species described here, there are now from this subgenus 37 species from the Neotropical Region, being 18 known from Brazil and 11 from the Amazonian Region. MATERIALS AND METHODSThe specimens described herein as a new species were collected by CDC light trap in São Geraldo do Araguaia and Juruti, PA. The specimens were mounted in phenol-balsam in the manner described by Wirth and Marston (1968). The types were deposited in the Invertebrate Collection of the Emílio Goeldi Paraense Museum (MPEG), PA, and in the Ceratopogonidae Collection of the Oswaldo Cruz Institute (CCeIOC), Rio de Janeiro. Diagnostic characters were illustrated using a camera lucida attached to an Olympus BH-2 miscroscope. Microphotographies of the wings were taken with a Nikon Eclipse E-800.In this paper, we follow the terminology established in Culicoides papers by Spinelli et al. (2005). Terms for wing veins follow the system of the Manual of Nearctic Diptera (McAlpine et al. 1981), with modifications proposed by Szadziewski (1996). The measurements of the spermathecae are in micrometers and those of the wings are in millimeters. Meristic information is given as range, following by the mean and number of specimens examined.Culicoides (Haematomyidium) jurutiensis, sp. nov.( Figs 1-7)Diagnosis -Only species in the subgenus Haematomyidium with two pale spots in cell r3 and m 1, hairy eyes and moderately separated, head and proboscis nearly similar in length, moderately long palpus, subequal spermathecae, mandible with 17-18 teeth.Female -Wing length 0.84 mm (n = 2), width 0.38 mm (n = 2).Head: dark brown. Eyes (Fig. 2) separated by distance equal to diameter of 1.5 ommatidia, with numerous interommatidial spicules.
