“…Along with the globalization of trade and travel, this has resulted in a dramatic and still ongoing global expansion of the geographic distribution of this species (Benedict et al 2007), increasing public health concerns about its role as a disease vector. Although there is a rapidly growing body of literature on the ecology of A. albopictus and its breeding site preferences in various countries and different regions (e.g., Chan et al 1971, Sprenger and Wuithiranyagool 1986, Nasci et al 1989, Cornel and Hunt 1991, Hobbs et al 1991, Abdul Kader et al 1997, Ishak et al 1997, Moore and Mitchell 1997, Fontenille and Toto 2001, Tsuda and Takagi 2001, Tsuda et al 2002, Lounibos 2002, Hiriyan et al 2003, Hiriyan and Tyagi 2004, Regu et al 2008, Singh et al 2008, Sumodan 2008, Rao 2010, no such study had been conducted in Nepal where this species is known to have been present in the area of the capital Kathmandu since at least 1969 (Darsie and Pradhan 1990). Here, we report on an entomological survey of A. albopictus larvae and pupae carried out to study the artificial container preference of this species in the urban areas of Kathmandu and Lalitpur districts of Nepal from April 2009 to March 2010.…”

In various countries the Asian Tiger Mosquito (Aedes albopictus) is a known vector of dengue and chikungunya viruses and other pathogens, but its ecology and role in disease transmission in Nepal has not been studied yet. Here, we report on an investigation of the seasonal distribution of potential artificial breeding habitats of A. albopictus in urban areas of the Kathmandu and Lalitpur districts of Nepal. Larval collections were performed from April 2009 to March 2010 simultaneously in all the wet containers present in and around the houses of the study areas. Altogether 1873 water containers in Kathmandu district and 1807 in Lalitpur district were searched in 12 months, out of which 107 (5.7%) and 129 (7.1%), respectively, were found positive for A. albopictus breeding. Within the urban agglomeration of both districts, the breeding was found to vary between localities. Immature stages of A. albopictus were recorded in pre-monsoon, monsoon and post-monsoon seasons as 1.9%, 6.7% and 5.6%, respectively, in wet containers in Kathmandu district. In Lalitpur district, A. albopictus larvae were detected in 4.6%, 7.6% and 7.1% of the wet containers in the pre-monsoon, monsoon and post-monsoon, respectively. The breeding preference ratio during all seasons was highest for discarded tires lying outdoors in both Kathmandu and Lalitpur districts. Among nine container types searched and examined, 95% of discarded tires were found positive for A. albopictus larvae and pupae, followed by metal drums (2%) and plastic drums (1.25%). Continued and increased urbanization and vehicle movement in Kathmandu and Lalitpur districts have resulted in increased amounts of non-biodegradable containers such as tires around human dwellings, thereby creating ideal breeding habitats for A. albopictus.

“…The species was already present in Brazil (1985) and is now occurring throughout South America, except Chile (Forattini, 1986;Reiter, 2010b). It has spread rapidly in Africa, with infestations identified in southeast Nigeria (1991), Cameroon (2000, Equatorial Guinea (2003), Gabon (2007), Central African Republic (2010), Algeria (2010) (Diallo et al, 2010;Fontenille & Toto, 2001;Gubler, 2003;Izri et al, 2010;Pages et al, 2009;Toto et al, 2003) and is also reported from Lebanon, Syria and Israel (Reiter, 2010a (Aranda et al, 2006;Dalla Pozza & Majori, 1992;Reiter, 2010b;Schaffner & Karch, 2000;Scholte & Schaffner, 2007).

“…a mosquito that lays its eggs in water-filled tree-holes) has been inadvertently spread around the world (largely via the used-tyre and tropical-plant trades) and is now established in many cities outside of its natural range, where elevated temperatures, humidity and artificial water pools have enabled it to thrive (Pluskota et al, 2008;Roiz et al, 2011). This species can transmit a number of pathogens of public-health importance, including West Nile virus, yellow fever virus, St Louis Encephalitis virus, dengue fever virus (Fontenille & Toto, 2001) and chikungunya fever virus. An outbreak of chikungunya fever (a disease originally endemic to East Africa) in Italy demonstrates that the introduction of mosquito vectors, such as the Asian tiger mosquito, can eventually be followed by their associated pathogens (Angelini et al, 2007;Bonilauri et al, 2008).…”

Mosquito-borne pathogens pose major threats to both wildlife and human health and, largely as a result of unintentional human-aided dispersal of their vector species, their cumulative threat is on the rise. Anthropogenic climate change is expected to be an increasingly significant driver of mosquito dispersal and associated disease spread. The potential health implications of changes in the spatio-temporal distribution of mosquitoes highlight the importance of ongoing surveillance and, where necessary, vector control and other health-management measures. The World Association of Zoos and Aquariums initiative, Project MOSI, was established to help protect vulnerable wildlife species in zoological facilities from mosquito-transmitted pathogens by establishing a zoo-based network of fixed mosquito monitoring sites to assist wildlife health management and contribute data on mosquito spatio-temporal distribution changes. A pilot study for Project MOSI is described here, including project rationale and results that confirm the feasibility of conducting basic standardized year-round mosquito trapping and monitoring in a zoo environment.Key-words: attractants; climate change; monitoring; mosquitoes; Project MOSI; surveillance; spatio-temporal distribution; wildlife health; zoological networks. MOSQUITO-RELATED HEALTH ISSUES FOR ZOOS AND SIMILAR FACILITIESMosquitoes are the principal vectors of a wide range of diseases, including human and avian malaria, dengue, West Nile encephalitis and filariasis (Becker et al., 2010; Kilpatrick & Randolph, 2012; World Health Organization, 2013a). A range of species has been recorded as succumbing to mosquito-transmitted pathogens in zoos and theme parks. Documented cases include African black-footed penguins Spheniscus demersus with avian malaria (Grim et al., 2004) and eastern equine encephalitis virus (Tuttle et al., 2005), Great gray owls Strix nebulosa with Usutu virus (Weissenböck et al., 2002), Humbolt penguins Spheiniscus humboldti with heartworms Dirofilaria immitis (Sano et al., 2005), and a Polar bear Ursus maritimus (Dutton et al., 2009) and two OrcasOrcinus orca with West Nile virus infection (Jett & Ventre, 2013).Blood-feeding mosquitoes have the ability to track airborne chemicals produced by the vertebrate host to locate them in order to have a blood meal, which is essential for viable egg production in most species (Dekker & Cardé, 2011). The combination of odours varies amongst species and mosquitoes can be more or less attracted to them depending on their feeding preference, even if, at close range, proximity to the host is likely to be more important than species identity (Takken & Verhulst, 2013). Several mosquito species are true 'generalists' as far as host species preference is concerned.Understanding distribution, population abundance, activity periods and other behaviours of mosquito species helps optimize protection efforts for human, domestic-animal and wildlife 3 populations (Becker et al., 2010; World Health Organization, 2013a).
