To Create A Buzz About Mosquitoes And Ecology I Have City Kids Make Comic Books

Katherine Richardson Bruna, Iowa State University If humans and mosquitoes had a battle at the end of the world, who would win? That’s the question I pose to 30 young kids each summer during a two-week camp called “Mosquitoes & Me” in Des Moines, Iowa. The ‘Mosquito and Me’ summer camp in Des Moines, Iowa. I am an educational anthropologist who studies the cultural dynamics of science education. Along with my colleagues Lyric Bartholomay and Sara Erickson, who help run the camp, we have the young camp participants explore the “end-of-world battle” question as they learn about mosquito biology, ecology and disease transmission. Based on what the kids learn from their hands-on activities, they design a mosquito comic book character that is either a hero or a villain. Since this approac...

An argument for gene drive technology to genetically control insects like mosquitoes and locusts

The fate of society rests in part on how humans navigate their complicated relationship with insects – trying to save “good” insects and control “bad” ones. Some insects, like mosquitoes, bite people and make them sick – remember Zika? Now the U.S. mosquito season is already in full swing, with over 10 cases of Dengue fever reported in the Florida Keys this year. Some insects, like bees, are pollinators that help produce our food. Others, like locusts, currently threaten crops in East Africa and Asia, preferring to eat our food instead. Insects have proven themselves extremely capable at evolving strategies to get around control methods, such as chemical insecticides and habitat modification, and current pest control technologies are simply not keeping up. We are both insect scientists. ...

Genetically modified mosquitoes could be released in Florida and Texas beginning this summer – silver bullet or jumping the gun?

This summer, for the first time, genetically modified mosquitoes could be released in the U.S. On May 1, 2020, the company Oxitec received an experimental use permit from the U.S. Environmental Protection Agency to release millions of GM mosquitoes (labeled by Oxitec as OX5034) every week over the next two years in Florida and Texas. Females of this mosquito species, Aedes aegypti, transmit dengue, chikungunya, yellow fever and Zika viruses. When these lab-bred GM males are released and mate with wild females, their female offspring die. Continual, large-scale releases of these OX5034 GM males should eventually cause the temporary collapse of a wild population. However, as vector biologists, geneticists, policy experts and bioethicists, we are concerned that current government oversight ...
