@Deepti they had that on news the other night and as mozzi doesn't fly far they were going around Cairns making sure there was no pools or containers with water in for them to breed.Its great to see that the bacteria is transferred with the eggs to the next generation off the mozzi.

i'm always a bit weary of any cure/preventative measure that involves infecting a species or spreading a man-made substance such as this bacteria.
I'm no scientist though so i may not know what i'm talking about....just the thought of spreading genetically engineered bacteria to carriers of a virus (some of which might sting a person after all) seems a bit scary to me. what if the bacteria ends up having a harmful effect on the person that is stung by such a mosquito? Or what if the dengue virus develops an immunity against these bacteria and evolves into a whole new virus? Or is that completely out of the question? If anyone has some more information on this, i'd really appreciate to hear your thoughts!

In the pacific northwest, the gypsy moth can wreak havoc on fir trees. For years, a biologic agent has been used effectively, without residual effect, or so they say.
Bacillus thuringiensis (Bt) is microbial and biological. It is the most commonly used pesticide. In addition to being used against the gypsy moth, Bt is used against a number of other pests, including the western spruce budworm and other Choristoneura, and tent caterpillar. When Bt is taken internally, the insect becomes paralyzed, stops feeding, and dies of starvation or disease
