I have no issue with modifying genetics normally, but why in the world would you modify a fungus to produce spider toxin? Fungi are far more advanced and intertwined with the biosphere than most people realize. What if they escape and run amok?
Why not just modify the mosquito which has been shown to work?
Why would they run amok? Does the spider toxin give them a survival advantage relative to its energetic cost? If the toxin merely allows them to kill the insects they infect, I believe it'd just tamp down the population without downright eliminating it.
