In a related story, plans to release genetically modified (GM) mosquitoes in Queensland have been delayed. Local experts, perhaps most notably local author Perran Ross, have raised some very serious concerns. Their concerns are rooted in the necessity and implications of this technology at this point in time. Although Ross recognizes the importance of this kind of genetic technology, he stresses that these changes are not needed in Queensland at this time.
The GM mosquito initiative, which was designed to help eliminate mosquito-borne diseases, came under criticism in the U.S. for its possible ecological effects. Ross stated, “It’s certainly good to have other technologies available. In this particular case, I just don’t think there’s a need for it.” His comments are keeping with a burgeoning mood among experts that the days of needing new strategies for disease control may be coming to an end.
Success of Existing Strategies
Dr. Andrea Britton, co-convenor of the Australian Local Public Health Association, welcomed the announcement to withdraw the GM mosquito application. She’s confident and hopeful that this decision is what their community needs now. She pointed out that Queensland is doing an operational release using Wolbachia. Animal Health FCC Environmental Services This naturally occurring bacteria defense is preventing the spread of the deadly dengue virus by mosquitoes. Britton explained that this approach has been incredibly effective in getting mosquito populations under control.
Britton elaborated on the effectiveness of the Wolbachia strategy, stating, “There’s already a very effective multi-pronged strategy … so to invest in something else may not be a good business case or cost-effective.” This viewpoint underscores a growing skepticism to further experimentation with new technologies when current alternatives are producing successful outcomes.
Future Considerations and Risk Assessments
Even with this blow to the GM mosquito proposal, Britton made it clear that we should still be open to future innovations. She said that the community association supported the recent withdrawal of the application. She further indicated that they would give a critical eye to any new proposals should they arise. “If a new application comes through, we’d have to look at the risk assessment of that and the data that’s presented from a public health point of view,” she explained.
Furthermore, Britton expressed concerns that the effects of releasing genetically modified mosquitoes on local ecosystems had not been sufficiently studied. She remarked, “Fish, bats, insects are potentially eating these genetically modified mosquitoes and you need to see the effect.” This announcement highlights the importance of robust ecological risk assessments prior to introducing any genetic alterations.
