This is great news. Dengue was a constant problem in my home country of Malaysia, and remains a problem to this day. I still remember all the public education campaigns about it that I saw when I was young (random ads on TV about making sure there's no stagnant water, seeking medical help if you notice <symptoms>, etc), I'm very glad that there are easily implementable solutions to these problems.

As a side note, I wonder why this kind of research is not more popular in university labs of tropical countries. Malaysia, Singapore, India, etc are home to plenty of university labs that should have the expertise and motivation to do this kind of thing, but they're really dropping the ball if they're not working on it right now. Every time I read about new mosquito fighting innovations it's out of an American or European lab, far away from where it's most impactful.

Is it a problem of funding? Somehow the Malaysian government funds less mosquito disease research than the US? Political will? I would hope that the health ministries of tropical countries are willing to throw some money at the problem. Institutional knowledge? Plenty of the professors are educated in Australia/UK/US, so that can't be it. Coverage? Western media covers western labs, and don't notice when labs elsewhere do the same thing?
