  • Assessment and an Updated List of the Mosquitoes of Saudi Arabia Azzam M
    Alahmed et al. Parasites Vectors (2019) 12:356 https://doi.org/10.1186/s13071-019-3579-4 Parasites & Vectors RESEARCH Open Access Assessment and an updated list of the mosquitoes of Saudi Arabia Azzam M. Alahmed1, Kashif Munawar1*, Sayed M. S. Khalil1,2 and Ralph E. Harbach3 Abstract Background: Mosquito-borne pathogens are important causes of diseases in the Kingdom of Saudi Arabia. Knowl- edge of the mosquito fauna is needed for the appropriate control of the vectors that transmit the pathogens and prevent the diseases they cause. An important frst step is to have an up-to-date list of the species known to be present in the country. Original occurrence records were obtained from published literature and critically scrutinized to compile a list of the mosquito species that occur within the borders of the Kingdom. Results: Fifty-one species have been recorded in the Kingdom; however, the occurrence of two of these species is unlikely. Thus, the mosquito fauna of the Kingdom comprises 49 species that include 18 anophelines and 31 culicines. Published records are provided for each species. Problematic records based on misidentifcations and inappropriate sources are discussed and annotated for clarity. Conclusion: Integrated morphological and molecular methods of identifcation are needed to refne the list of spe- cies and accurately document their distributions in the Kingdom.

  • Potentialities for Accidental Establishment of Exotic Mosquitoes in Hawaii1
    Vol. XVII, No. 3, August, 1961 403 Potentialities for Accidental Establishment of Exotic Mosquitoes in Hawaii1 C. R. Joyce PUBLIC HEALTH SERVICE QUARANTINE STATION U.S. DEPARTMENT OF HEALTH, EDUCATION, AND WELFARE HONOLULU, HAWAII Public health workers frequently become concerned over the possibility of the introduction of exotic anophelines or other mosquito disease vectors into Hawaii. It is well known that many species of insects have been dispersed by various means of transportation and have become established along world trade routes. Hawaii is very fortunate in having so few species of disease-carrying or pest mosquitoes. Actually only three species are found here, exclusive of the two purposely introduced Toxorhynchites. Mosquitoes still get aboard aircraft and surface vessels, however, and some have been transported to new areas where they have become established (Hughes and Porter, 1956). Mosquitoes were unknown in Hawaii until early in the 19th century (Hardy, I960). The night biting mosquito, Culex quinquefasciatus Say, is believed to have arrived by sailing vessels between 1826 and 1830, breeding in water casks aboard the vessels. Van Dine (1904) indicated that mosquitoes were introduced into the port of Lahaina, Maui, in 1826 by the "Wellington." The early sailing vessels are known to have been commonly plagued with mosquitoes breeding in their water supply, in wooden tanks, barrels, lifeboats, and other fresh water con tainers aboard the vessels, The two day biting mosquitoes, Aedes ae^pti (Linnaeus) and Aedes albopictus (Skuse) arrived somewhat later, presumably on sailing vessels. Aedes aegypti probably came from the east and Aedes albopictus came from the western Pacific.

  • 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.

  • ARTHROPODA Subphylum Hexapoda Protura, Springtails, Diplura, and Insects

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).

Introduction The first list of the mosquitoes of Turkey is to be found in Martini's (1929-31) Die Fliegen der palaearktischen Region. A succession of workers, notably Akalin (1936), Irdem (1940; 1941; 1943), Siiyev (1953), Parrish (1959), GOkberk (1%1; 1970), Erel (1%7), Postiglione et al. (1970; 1972; 1973), Coluzzi et al. (1974), Lane (1982; 1985; 1992) and Alten et al. (2000), have since added to or amended this list as new data became available. Recent major taxonomic revision affecting genera, subgenera and species of the tribe Aedini (Reinert, 1999a, 1999b, 1999c, 2ooOa, 2oo0b, 2000c, 2000d) places western Palaearctic members of this tribe in the genus Aedes (containing the subgenera Aedes, Aedimorphus, Fredwardsius and Stegomyia) or the genus Ochlerotatus (containing the subgenera Finlaya, Ochlerotatus and Rusticoidus). Thus, the 50 currently recognised endemic species of mosquito in Turkey are now placed in the genera Anopheles (10), Aedes (3), Ochlerotatus (15), Culex (13), Culiseta (6), Coquillettidia (1), Orthopodomyia (1) and Uranotaenia (1). The revised list presented here will undoubtedly lengthen as morphological studies are reinforced by cyto- genetic, iso-enzyme and/or DNA sequencing analysis, and as more field data become available.

SCIENTIFIC NOTE DISTRIBUTION EXPANSION OF CULEX CORONATOR IN ALABAMA KATHERINE M. GRAY,1 NATHAN D. BURKETT-CADENA 2,4 AND MICKY D. EUBANKS3 ABSTRACT. Culex coronator, a mosquito species common to the American tropics, has been recently documented from a number of temperate areas in the USA. Since 2002 specimens have been reported for the first time from Oklahoma, Louisiana, Mississippi, Alabama, and Florida. Here we provide new collection records for Cx. coronator in east-central Alabama. In October 2007, 2 larvae of Cx. coronator were collected from an artificial container in Tuskegee National Forest in Macon County, AL. The distribution of Cx. coronator in the USA seems to be expanding at a prodigious rate, for reasons that remain unclear. KEY WORDS Culex coronator, distribution expansion Culex coronator Dyar and Knab is a mosquito Cadena using published keys (Darsie and Ward species common to the American tropics and 2005). The container in which larvae were subtropics that breeds in rain-filled depressions collected was a 35-gallon black plastic garbage and water-filled manmade containers (Dyar and can placed at the study site in February of the Knab 1906).

We identified Culex mosquito species and subspecies using taxonomic keys, and then we used the polymerase chain reaction technique (PCR) as an integrated tool to confirm and refine the list of Culex mosquito species in the region. Phylogenetic trees were constructed for the identified species, and their distinctive clustering was compared with their reference’s species in the GenBank.

The current classification of the subgenus recognizes a total of 160 species divided in two major sections, Melanoconion and Spissipes; and several non-formal groupings within each section. We gathered bibliographic records of the subgenus in South America, with particular focus on the period of time after the publication of the Catalog by Pecor et al. (1992) until present time. This compilation included 139 species occurring in South American countries with all the relevant bibliographic sources, including the corresponding information for those medically important species. Key words: Culex, Melanoconion, Spissipes Section, Melanoconion Section, taxonomy, South America Introduction Species of Culex subgenus Melanoconion Theobald represent a diverse group widely distributed in the Americas. There are 160 species considered within the subgenus and members of this group are known to occur in the southern part of North America, including United States and Mexico, Central America, some of the Caribbean islands such as Trinidad, Tobago, Jamaica, Martinique and Puerto Rico, among others; and in most of South American countries (Pecor et al.

Their ability to adapt and expand worldwide increases spread of mosquito-borne diseases. Climate changes contribute in enhancing these “epidemic conditions”. Understanding the effect of weather variables on mosquito seasonality and host searching activity contributes towards risk control of the mosquito-borne disease outbreaks. To enable early detection of Aedes invasive species we developed a surveillance network for both invasive and native mosquitoes at the main point of entry for the first time in Cyprus. Mosquito sampling was carried out for one year (May 2017–June 2018), at bimonthly intervals around Limassol port.
