溫哥華的世界(Vancouver's World)

*******在溫哥華的夏天，避免在蚊子最活躍的時間待在戶外.......清晨   與   日落後的傍晚到天黑****

如果認為加拿大沒有蚊子(因為冬天下雪，溫度可零下好幾度)，那就錯了! 小小的蚊子沒有，但是夏天可有兇惡的蚊子，連穿上長褲與長袖，牠們仍可以叮進皮膚，留下紅斑點又癢的痕跡!




據政府的宣導.....因為2011的春季，內陸點的省分河水暴漲成水災，所以導致蚊子沿著菲莎河 (Fraser River) 流至卑斯省的出海口，沿岸的城市今年餮定比往年多出許多蚊子出來咬人。
有庭院需要割草的朋友，得選擇太陽仍在的下午4點到7點左右，否則太陽下山後，兇惡的蚊子就出來吃晚餐了!>>>>


**************以下有關2011夏天蚊子的訊息，載自 " the Province Newspaper" 2011/07/10*******

     Outdoor revellers beware(喜歡戶外的人小心了): the number of "nuisance討厭的" mosquitoes is skyrocketing this year.
     According to Randy Heilbron, Fraser Health's West Nile virus coordinator, high water levels on the Fraser River and throughout the province have created a cozy breeding ground for nuisance mosquitoes舒適的環境適合討厭的蚊子繁殖 - a type that does not carry viruses.(但不是帶病菌那類型)>>>>>>>




     "It's pretty pickety" Heilbron said. "All the way along the river from Hope...right down to the mouth of the river in Richmond." Heilbron said traps have been spread out across the Fraser Valley region to trap and count the number of adult mosquitoes in each area(每一年在整個菲沙流域區去捕捉與計算蚊子的困境已經延長) - and "there's a big difference" this year, he said.

     Adult mosquitoes lay their eggs in the soil the previous year and by late spring and early summer, eggs then begin to hatch into mosquitoes when the flood waters rise. But many mosquito-wary communities across the province are working to control the number of eggs that become pests(害蟲) by spraying BTI, a type of larvicide(殺幼蟲劑) that attacks mosquito larvae (幼蟲)in the water.>>>>>



     Dirk Lewis, a mosquito control program manager with Morrow BioScience Ltd., has worked with the Fraser Vally Regional District to try to curb(抑制) the number of bugs in the Fraser Valley region. Lewis said he and the mosquito control team have been spraying BTI along the water's edge from the Abbotsford-Mission area past Chilliwack and up to Hope.

     "We've seen a difference in flood water and there are a lot more adult mosquitoes right along the Fraser River corridor(菲沙河的通道)," Lewis said. But B.C. residents worried about West Nile will have to wait to see whether the summer will be a bad one for the virus. Heilbron said the number of vector mosquitoes(帶菌的蚊子) - those that carry viruses - won't peak until midsummer. >>>>>>



     "It's too early to tell" whether the West Nile virus will be a major problem this year, he said,  Heilbron said all B.C. residents should take precautions when outdoors. He suggested that people wear long-sleeved clothes with tight-woven fabric, use the DEET-based bug spray and avoid the outdoors during high mosquito activity times - early morning and late at night.(避免在蚊子最活躍的時間待在戶外.......清晨   與   日落後的傍晚到天黑)

     "When travelling to areas known to be endemic to West Nile virus, people should also take extra precautions," he said.
