Pesquisa sobre mosquito da dengue revela evolução do Aedes aegypti


O mosquito, que transmite a dengue, está se desenvolvendo em aquas sujas e  tb em água salgada, diz  Marylene de Brito Arduino pesquisadora da sucen (Superintendência de Controle de Endemias) de São Paulo.
A pesquisadora Marylene diz, ter encontrado larvas do Aedes em água com sal não significa que ele possa se reproduzir no mar. Ela está testando, no entanto, qual o limite de salinidade que as larvas suportam.
"É importante ressaltar que o sal mata as larvas do Aedes e continuamos recomendando seu uso no combate aos criadouros."
Estudo realizado por ela em São Sebastião mostrou que larvas do mosquito foram encontradas em recipientes com água com resíduos de sal e até em outros com produtos como graxa, tinta, cal e óleo combustível.
A pesquisadora diz que, o resultado mostra que é preciso se preocupar com possíveis criadouros antes ignorados, como latas de tinta e pneus com resto de óleo.
"O mosquito está evoluindo. Todas as espécies tentam manter sua população. Se não encontram o ambiente que preferiam antes, acabam se adaptando ao que existe."

Acho que está na hora da Prefeitura de Pres, médici-MA fazer uma campanha na nossa cidade de esclarecimento ara a nossa população, sobre a dengue, tem muitas pessoas com sintomas de dengue e outras com dengue mesmo......prevenir é melhor que remediar................e o Maranhão está na lista dos 16 Estados com maior propabilidade de ter uma epidemia da dengue.....O Governo do Estado também tem que deixar de drincar e cuidar da saúde................eu estou fazendo minha parte, nem quintal tenho p/ ficar alguma coisa, p/ acumular água limpa e parada....Esta postagem está 10.

Greetings, I'm Karolyn and I'm certainly pleased that I found blogger.
com. I have got a brief question that I’d like to ask if you don't mind. I was curious to find out how you center yourself and open up your mind before writing. I have had problems clearing my mind in order to get my ideas out. I love writing once I get into it, but in most cases I feel as if I end up wasting the first 10 to fifteen minutes pushing myself to concentrate. Do you have any advice or methods?

A fellow blogger here, found your site via Xoops, and I have a piece of advice:
write more. Honestly, you seem like you're tailoring the full article around the clip. It's obvious you know a lot, so why not use your knowledge to write something more substantial and keep the video as something supplementary (if there at all)?

Hey there, my name's Kenneth and sometimes I write about the same thing on my blog. Actually, if I may, let me ask you something.. Could it just be me or does it seem as if many of the replies appear they are coming out of brain dead people? :-P And, if you are writing on extra social sites like web 2.0 site list, I want to keep up to date with you. Could you put up a list of every one of your shared sites like your Twitter, Facebook page or linkedin profile?

Hey there, I'm a new blogger coming from Gap, France who found you on http://assisericeira.blogspot.com/. Do you have any useful tips for up-and-coming writers? I'm working on launching my own website soon but I
don't really know where to get started. Could you suggest starting with a free platform like Serendipity or go for a paid alternative? I'm facing quite a few options and it's all so daunting... What would you say?
