How can parasitic fungi help control emerald ash borers in Minnesota?

Researchers found that parasitic fungi can spread among emerald ash borers through mating, offering an effective way to eradicate the invasive pest population.

What are the next steps for the University of Minnesota beetle study?

The researchers plan to test the most effective fungi in devices across Minnesota's state parks and forests to assess their impact on beetle populations.

Why are invasive species like the emerald ash borer a problem?

Invasive species can devastate ecosystems by consuming vital resources, potentially leading to the extinction of native plants and animals and altering food chains.

Fungi Fight: Natural Weapon Targets Destructive Beetles

Scientists at the University of Minnesota have identified a potent natural ally in the battle against the invasive emerald ash borer. Research published in Forests indicates that certain parasitic fungi can be highly effective in eradicating these destructive beetles. The study found that once exposed to fungal spores, the beetles inadvertently spread the pathogens to others through mating and other interactions, creating a natural cycle of control.

The focus is now on practical application, with plans to deploy devices containing the most effective fungi across Minnesota's state parks and forests. This initiative aims to curb the beetle population and safeguard the state's significant ash tree population, estimated at one billion. Invasive species pose a significant threat to local ecosystems, disrupting food chains and potentially leading to extinctions.
