Bugs that survive insecticides grow stronger. And discovering new, effective toxins through genetics is time-consuming – finding the nexus between a particular bug and its poison can take decades. Now, scientists at Massachusetts’ Harvard University are using advanced PACE technology speed up the search for new Bt toxins to kill insecticide-resistant super-bugs.

New DNA tests for pesticide-resistant critters developed by researchers at New South Wales’ Yanco Agricultural Institute could revolutionise the way we protect valuable stored grain from insect pests.
