Knowledge about transmission remains incomplete, especially concerning potential transmission in geographic areas in which it has not yet been introduced. To identify unknown vectors of Zika, we developed a data-driven model linking vector species and the Zika virus via vector-virus trait combinations that confer a propensity toward associations in an ecological network connecting flaviviruses and their mosquito vectors. Our model predicts that thirty-five species may be able to transmit the virus, seven of which are found in the continental United States, including Culex quinquefasciatus and Cx. pipiens. We suggest that empirical studies prioritize these species to confirm predictions of vector competence, enabling the correct identification of populations at risk for transmission within the United States. *For correspondence: mvevans@ DOI: 10.7554/eLife.22053.001 uga.edu Competing interests: The authors declare that no competing interests exist. -

Some taxa are also considered to be indicators of environmental health. Despite the importance of understanding insect abundance and distribution to the understanding of disease dynamics and design strategies to manage them, very little is known about their ecology in many tropical regions. We studied the abundance and diversity of mosquitoes and sand flies in the Bahia State of Brazil, a point of origin for arbovirus outbreaks, including Zika and Chikungunya fever. During 2009-2014, 51 mosquito taxa were identified, belonging to three dipteran families, Ceratopogonidae, Culicidae, and Psychodidae. The family Culicidae, including the Sabethini tribe, were the most abundant (81.5%) and most taxa-rich (n=45). -

Identification Keys to the Anopheles Mosquitoes of South America
Sallum et al. Parasites Vectors (2020) 13:583 https://doi.org/10.1186/s13071-020-04298-6 Parasites & Vectors RESEARCH Open Access Identifcation keys to the Anopheles mosquitoes of South America (Diptera: Culicidae). I. Introduction Maria Anice Mureb Sallum1*, Ranulfo González Obando2, Nancy Carrejo2 and Richard C. Wilkerson3,4,5 Abstract Background: The worldwide genus Anopheles Meigen, 1918 is the only genus containing species evolved as vectors of human and simian malaria. Morbidity and mortality caused by Plasmodium Marchiafava & Celli, 1885 is tremendous, which has made these parasites and their vectors the objects of intense research aimed at mosquito identifcation, malaria control and elimination. DNA tools make the identifcation of Anopheles species both easier and more difcult. Easier in that putative species can nearly always be separated based on DNA data; more difcult in that attaching a scientifc name to a species is often problematic because morphological characters are often difcult to interpret or even see; and DNA technology might not be available and afordable. Added to this are the many species that are either not yet recognized or are similar to, or identical with, named species. The frst step in solving Anopheles identi- fcation problem is to attach a morphology-based formal or informal name to a specimen. These names are hypoth- eses to be tested with further morphological observations and/or DNA evidence. The overarching objective is to be able to communicate about a given species under study. In South America, morphological identifcation which is the frst step in the above process is often difcult because of lack of taxonomic expertise and/or inadequate identifca- tion keys, written for local fauna, containing the most consequential species, or obviously, do not include species described subsequent to key publication. -

And Haemagogus Mosquitoes in Southern Brazil (Diptera: Culicidae)*
BITING ACTIVITY OF AEDES SCAPULARIS (RONDANI) AND HAEMAGOGUS MOSQUITOES IN SOUTHERN BRAZIL (DIPTERA: CULICIDAE)* Oswaldo Paulo Forattini** Almério de Castro Gomes** FORATTINI, O. P. & GOMES, A. de C. Biting activity of Aedes scapularis (Rondani) and Haemagogus mosquitoes in Southern Brazil (Diptera: Culicidae). Rev. Saúde públ., S. Paulo, 22:84-93, 1988. ABSTRACT: The biting activity of a population of Aedes scapularis (Rondani), Hae- magogus capricornii Lutz and Hg. leucocelaenus (Dyar and Shannon) in Southern Brazil was studied between March 1980 and April 1983. Data were obtained with 25-hour human bait catches in three areas with patchy residual forests, named "Jacaré-Pepira", "Lupo" Farm, and "Sta. Helena" Farm, in the highland region of S. Paulo State (Brazil). Data obtained on Ae. scapularis were compared with those formerly gathered in the "Ribeira'' Valley lowlands, and were similar, except in the "Lupo" Farm study area, where a pre- crepuscular peak was observed, not recorded at the "Jacaré-Pepira" site or in the "Ribeira" Valley. In all the areas this mosquito showed diurnal and nocturnal activity, but was most active during the evening crepuscular period. These observations support the hypo- thesis about the successful adaptation of Ae. scapularis to man-made environments and have epidemiological implications that arise from it. As for Haemagogus, results obtained on the "Lupo" and "Sta. Helena" regions agree with previous data obtained in several other regions and show its diurnal activity. The proximity of "Lupo" Farm, where Hg. capricornii and Hg. leucocelaenus showed considerable activity, to "Araraquara" city where Aedes aegypti was recently found, raises some epidemiological considerations about the possibility of urban yellow fever resurgence. -
Identification Key to the Anopheles Mosquitoes of South America (Diptera: Culicidae). III. Male Genitalia

Parasites Vectors (2020) 13:542 https://doi.org/10.1186/s13071-020-04300-1 Parasites & Vectors RESEARCH Open Access Identifcation key to the Anopheles mosquitoes of South America (Diptera: Culicidae). III. Male genitalia Maria Anice Mureb Sallum1*, Ranulfo González Obando2, Nancy Carrejo2 and Richard C. Wilkerson3,4,5 Abstract Background: Accurate identifcation of the species of Anopheles Meigen, 1818 requires careful examination of all life stages. However, morphological characters, especially those of the females and fourth-instar larvae, show some degree of polymorphism and overlap among members of species complexes, and sometimes even within progenies. Characters of the male genitalia are structural and allow accurate identifcation of the majority of species, excluding only those in the Albitarsis Complex. In this key, based on the morphology of the male genitalia, traditionally used important characters are exploited together with additional characters that allow robust identifcation of male Anoph- eles mosquitoes in South America. Methods: Morphological characters of the male genitalia of South American species of the genus Anopheles were examined and employed to construct a comprehensive, illustrated identifcation key. For those species for which specimens were not available, illustrations were based on published illustrations. Photographs of key characters of the genitalia were obtained using a digital Canon Eos T3i attached to a light Diaplan Leitz microscope. The program Helicon Focus was used to build single in-focus images by stacking multiple images of the same structure. Results: An illustrated key to South American species of Anopheles based on the morphology of the male genitalia is presented, together with a glossary of morphological terms. -
