Yesterday, the Herald Journal did an interview with Chad and his lab. The article came out today! Front Page news! Congratulations Chad!!!
Squash that pest

Call it a Mormon cricket’s worst nightmare.Utah State University scientists are researching a fungus that eats the insects alive by depositing spores inside them that multiply and eventually break through their exoskeletons.
The fungus is already providing an organic method of controlling crickets and grasshoppers in places like Australia, Africa and South America. Now the USU team is searching for it in the U.S.
“We can’t import it (the fungus) from other countries because of EPA restrictions,” explained Chad Keyser, a graduate student in biology. “They’re very careful about bringing in exotic species from other places.”
As part of the effort, Roberts’ team is analyzing 10,000 soil samples gathered by the U.S. Department of Agriculture in 17 states. Lab technicians isolate fungus within the dirt and grow it in petri dishes. The results are tested on Mormon crickets, though the fungus will also be effective on grasshoppers.
“The Mormon cricket is not a traditional cricket,” Roberts
explained. “It is really a katydid. It is closer to the grasshoppers than a lot of the crickets.”
Keyser said that so far some of the samples have killed 80 percent of the bugs they’ve tested.
In addition, the fungus is more environmentally friendly than current pesticides.
“It won’t harm fish or mammals, though it could kill non-target insects,” Roberts said.
Keyser said he believes that farmers could use the fungus and maintain an organic certification. However, he said that fungus probably could not replace all chemical pesticides because it works too slowly to stop massive insect plagues like those affecting Tooele.
In addition, the fungus can be finicky. Temperature and weather conditions can affect its potency.
Still, the researchers say they are excited by the possibilities of commercializing the fungus into a product that gardeners can spray on their crops.
“We aren’t looking to the future,” Roberts said. “We buy pesticides, we throw them out and we never look at what we can do better.”
