Twenty Years of Surveillance for Eastern Equine Encephalitis Virus In
Oliver et al. Parasites & Vectors (2018) 11:362 https://doi.org/10.1186/s13071-018-2950-1 RESEARCH Open Access Twenty years of surveillance for Eastern equine encephalitis virus in mosquitoes in New York State from 1993 to 2012 JoAnne Oliver1,2*, Gary Lukacik3, John Kokas4, Scott R. Campbell5, Laura D. Kramer6,7, James A. Sherwood1 and John J. Howard1 Abstract Background: The year 1971 was the first time in New York State (NYS) that Eastern equine encephalitis virus (EEEV) was identified in mosquitoes, in Culiseta melanura and Culiseta morsitans. At that time, state and county health departments began surveillance for EEEV in mosquitoes. Methods: From 1993 to 2012, county health departments continued voluntary participation with the state health department in mosquito and arbovirus surveillance. Adult female mosquitoes were trapped, identified, and pooled. Mosquito pools were tested for EEEV by Vero cell culture each of the twenty years. Beginning in 2000, mosquito extracts and cell culture supernatant were tested by reverse transcriptase-polymerase chain reaction (RT-PCR). Results: During the years 1993 to 2012, EEEV was identified in: Culiseta melanura, Culiseta morsitans, Coquillettidia perturbans, Aedes canadensis (Ochlerotatus canadensis), Aedes vexans, Anopheles punctipennis, Anopheles quadrimaculatus, Psorophora ferox, Culex salinarius, and Culex pipiens-restuans group. EEEV was detected in 427 adult mosquito pools of 107,156 pools tested totaling 3.96 million mosquitoes. Detections of EEEV occurred in three geographical regions of NYS: Sullivan County, Suffolk County, and the contiguous counties of Madison, Oneida, Onondaga and Oswego. Detections of EEEV in mosquitoes occurred every year from 2003 to 2012, inclusive. EEEV was not detected in 1995, and 1998 to 2002, inclusive. -

H aldimand-norfolk HE a LT H U N I T HEALTHINFO H e a lt H y e nvironment T E a m eastern equine encephalitis (EEE) What is eastern equine encephalitis? Eastern Equine Encephalitis (EEE), some- times called sleeping sickness or Triple E, is a rare but serious viral disease spread by infected mosquitoes. How is eastern equine encephalitis transmitted? The Eastern equine encephalitis virus (EEEv) can infect a wide range of hosts including mammals, birds, reptiles and amphibians. Infection occurs through the bite of an infected mosquito. The virus itself is maintained in nature through a cycle between Culiseta melan- ura mosquitoes and birds. Culiseta mel- anura mosquitoes feed almost exclusively on birds, so they are not considered an important vector of EEEv to humans or other mammals. Transmission of EEEv to humans requires mosquito species capable of creating a “bridge” between infected birds and uninfected mammals. Other species of mosquitoes (including Coquiletidia per- Coast states.

A Mosquito Psorophora Ciliata (Fabricius) (Insecta: Diptera: Culicidae)1 Ephraim V
EENY-540 A Mosquito Psorophora ciliata (Fabricius) (Insecta: Diptera: Culicidae)1 Ephraim V. Ragasa and Phillip E. Kaufman2 Introduction For additional information on mosquitoes, see http://edis. ifas.ufl.edu/IN652. Psorophora ciliata (Fabricius) is a large mosquito (Cutwa and O’Meara 2005) that has developed an outsized reputa- tion because of its relatively intimidating heft and persistent Synonymy biting behavior (Gladney and Turner 1969), including Psorophora ciliata (Fabricius 1794) anecdotal historical accounts of its legendary aggressiveness Culex ciliata Fabricius (1794) (Wallis and Whitman 1971) and ‘frightening appearance’ Culex conterrens Walker (1856) (King et al. 1960). The ‘gallinipper’ or ‘shaggy-legged Culex molestus Weidemann (1820) gallinipper’ was used as a common name for Psorophora Culex rubidus Robineau-Desvoidy (1827) ciliata in various published reports (Ross 1947; King et al. Psorophora boscii Robineau-Desvoidy (1827) 1960; Breeland et al. 1961; Goddard et al. 2009). The term Psorophora ctites Dyar (1918) was mentioned much earlier by Flanery (1897) describing (From ITIS 2011) the mosquito as ‘the little zebra-legged thing—the shyest, slyest, meanest, and most venomous of them all’ [sic] but Distribution did not specify what species it was. The word gallinipper Psorophora ciliata usually is associated with other flood- originated as a vernacular term in the southeastern region water mosquitoes, including many species from the Aedes of the United States referring to ‘a large mosquito or other genera (Breeland et al. 1961), and has a wide distribution insect that has a painful bite or sting’ and has appeared in the New World. Floodwater mosquitoes often lay in folk tales, traditional minstrel songs, and a blues their eggs in low-lying areas with damp soil and grassy song referencing a large mosquito with a ‘fearsome bite’ overgrowth. -

A MONOGRAPH OFTHE CULICIDAE OF THE WORLD. GENERAL NOTES. Several notes of general interest have been made and sent by correspondents that can scarcely be incorporated in the systematic part of this book. These are presented here. THE RELATIVEFREQUENCE OF CULICINAAND ANOPHELINA. It is interesting to note the relative frequence of these two sections of the CFulicidae. In most cases observations made personally during the past two years show that in Great Rritain the Anophelina, where they occur at all, are relatively more abundant in habitations than Culex. At Great Staughton during August the numbers counted in a privy in the morning were as follows during the week ending the 26th :-- 20th . 10 AM. Culex 12 ; Anopheles 37 21st . ,) .

Aedes (Ochlerotatus) vexans (Meigen, 1830) Floodwater mosquito NZ Status: Not present – Unwanted Organism Photo: 2015 NZB, M. Chaplin, Interception 22.2.15 Auckland Vector and Pest Status Aedes vexans is one of the most important pest species in floodwater areas in the northwest America and Germany in the Rhine Valley and are associated with Ae. sticticus (Meigen) (Gjullin and Eddy, 1972: Becker and Ludwig, 1983). Ae. vexans are capable of transmitting Eastern equine encephalitis virus (EEE), Western equine encephalitis virus (WEE), SLE, West Nile Virus (WNV) (Turell et al. 2005; Balenghien et al. 2006). It is also a vector of dog heartworm (Reinert 1973). In studies by Otake et al., 2002, it could be shown, that Ae. vexans can transmit porcine reproductive and respiratory syndrome virus (PRRSV) in pigs. Version 3: Mar 2015 Geographic Distribution Originally from Canada, where it is one of the most widely distributed species, it spread to USA and UK in the 1920’s, to Thailand in the 1970’s and from there to Germany in the 1980’s, to Norway (2000), and to Japan and China in 2010. In Australia Ae. vexans was firstly recorded 1996 (Johansen et al 2005). Now Ae. vexans is a cosmopolite and is distributed in the Holarctic, Orientalis, Mexico, Central America, Transvaal-region and the Pacific Islands. More records of this species are from: Canada, USA, Mexico, Guatemala, United Kingdom, France, Germany, Austria, Netherlands, Denmark, Sweden Finland, Norway, Spain, Greece, Italy, Croatia, Czech Republic, Hungary, Bulgaria, Poland, Romania, Slovakia, Yugoslavia (Serbia and Montenegro), Turkey, Russia, Algeria, Libya, South Africa, Iran, Iraq, Afghanistan, Vietnam, Yemen, Cambodia, China, Taiwan, Bangladesh, Pakistan, India, Sri Lanka, Indonesia (Lien et al, 1975; Lee et al 1984), Malaysia, Thailand, Laos, Burma, Palau, Philippines, Micronesia, New Caledonia, Fiji, Tonga, Samoa, Vanuatu, Tuvalu, New Zealand (Tokelau), Australia. -
A Classification System for Mosquito Life Cycles: Life Cycle Types for Mosquitoes of the Northeastern United States
June, 2004 Journal of Vector Ecology 1 Distinguished Achievement Award Presentation at the 2003 Society for Vector Ecology Meeting A classification system for mosquito life cycles: life cycle types for mosquitoes of the northeastern United States Wayne J. Crans Mosquito Research and Control, Department of Entomology, Rutgers University, 180 Jones Avenue, New Brunswick, NJ 08901, U.S.A. Received 8 January 2004; Accepted 16 January 2004 ABSTRACT: A system for the classification of mosquito life cycle types is presented for mosquito species found in the northeastern United States. Primary subdivisions include Univoltine Aedine, Multivoltine Aedine, Multivoltine Culex/Anopheles, and Unique Life Cycle Types. A montotypic subdivision groups life cycle types restricted to single species. The classification system recognizes 11 shared life cycle types and three that are limited to single species. Criteria for assignments include: 1) where the eggs are laid, 2) typical larval habitat, 3) number of generations per year, and 4) stage of the life cycle that overwinters. The 14 types in the northeast have been named for common model species. A list of species for each life cycle type is provided to serve as a teaching aid for students of mosquito biology.

Linking Bird and Mosquito Data to Assess Spatiotemporal West Nile Virus Risk in Humans
EcoHealth https://doi.org/10.1007/s10393-019-01393-8 Ó 2019 EcoHealth Alliance Original Contribution Linking Bird and Mosquito Data to Assess Spatiotemporal West Nile Virus Risk in Humans Benoit Talbot ,1 Merlin Caron-Le´vesque,1 Mark Ardis,2 Roman Kryuchkov,1 and Manisha A. Kulkarni1 1School of Epidemiology and Public Health, University of Ottawa, Room 217A, 600 Peter Morand Crescent, Ottawa, ON K1G 5Z3, Canada 2GDG Environnement, Trois-Rivie`res, QC, Canada Abstract: West Nile virus (WNV; family Flaviviridae) causes a disease in humans that may develop into a deadly neuroinvasive disease. In North America, several peridomestic bird species can develop sufficient viremia to infect blood-feeding mosquito vectors without succumbing to the virus. Mosquito species from the genus Culex, Aedes and Ochlerotatus display variable host preferences, ranging between birds and mammals, including humans, and may bridge transmission among avian hosts and contribute to spill-over transmission to humans. In this study, we aimed to test the effect of density of three mosquito species and two avian species on WNV mosquito infection rates and investigated the link between spatiotemporal clusters of high mosquito infection rates and clusters of human WNV cases. We based our study around the city of Ottawa, Canada, between the year 2007 and 2014. We found a large effect size of density of two mosquito species on mosquito infection rates. We also found spatiotemporal overlap between a cluster of high mosquito infection rates and a cluster of human WNV cases. Our study is innovative because it suggests a role of avian and mosquito densities on mosquito infection rates and, in turn, on hotspots of human WNV cases. -
