Index of Subjects <html> <body> <font size=3>From certain of the literature, it seems that "<i>Ochlerotatus japonicus" </i>is not to be messed with! (Perhaps that could be said of all the mosquitoes found in NS?)<br> Here is one reference:</font> <ul> General impacts</b> Ochlerotatus j. japonicus</i> is a species of mosquito with an aggressive opportunistic feeding habit, taking bloodmeals from avian and mammalian hosts, with a preference for human blood (Molaei et al</i>., 2009). Laboratory studies have shown Oc. j. japonicus</i> to be an efficient vector of <a href="http://www.issg.org/database/species/../species/ecology.asp?si=304&fr=1&sts=sss&lang=EN">West Nile Virus (WNV)</a> but its role in the natural transmission of the virus is unknown (Scott, 2010; Molaei et al</i>., 2009). Furthermore WNV has been detected in field-collected Oc. j. japonicus</i> is at least nine different states. It is thus very likely that this species could serve as a bridge vector of the WNV to humans. <br><br> Oc. j. japonicus</i> is also a highly efficient vector of St. Louis encephalitis virus and a moderately efficient vector of eastern equine encephalitis and La Crosse viruses in laboratory tests. It has also been known to transmit Japanese B encephalitis to humans (Molaei et al</i>., 2009; Andreadis et al</i>., 2001; Sardelis et al</i>., 2003; Sardelis et al</i>., 2002). <br> Larvae of Oc. j. japonicus</i> are highly effective competitors and can reduce populations of native mosquito populations significantly through interspecific competition for limited resources. Surveys in Connecticut in 2005 revealed that Oc. j. japonicus</i> was the dominant species collected in all waste tyres and natural rock pool environments. Comparisons with data from previous years indicated significant decline of native species including Oc. atropalpus</i>, Oc. triseriatus</i> and Culex restuans</i>. </ul>Angus<br><br> <br> <font size=3>At 10:48 PM 8/8/2011, you wrote:<br> <blockquote type=cite class=cite cite>While wandering the neighborhood recently (Dartmouth) I came across an old metal container filled with water and mosquito larvae and pupae (tumblers) . I collected about thirty tumblers in jars to check the species. The first ten or so that hatched were Common Rain Barrel Mosquito (<i>Culex pipiens</i>). The next ten or so were Japanese Mosquito (<i>Ochlerotatus japonicus</i>). This species was first found in North America in New Jersey in 1998. It was first reported in New Brunswick in 2005. It was reported in Nova Scortia in 2008 (Jeff Ogden). It may prove to be one of the most common mosquitoes in the HRM. Its rapid expansion is amazing, spreading in 13 years to more than twenty states and at least four provinces.<br> It is a container breeding species and beautifully colored with a striped golden back, silver spots on the thorax and abdomen and black legs broadly striped with white below the joints.<br> Jim Edsall <br> Dartmouth, N.S.<br> check out my personal website at <br> http://www3.ns.sympatico.ca/jim.edsall/</font></blockquote></body> </html>
