Tree and bug experts across Iowa are keeping an eye out for the walnut twig beetle – a tiny insect that could damage Iowa’s black walnut industry.
The beetle carries a fungus known as thousand cankers disease, which can kill a tree within three to five years of it first showing symptoms.
The Iowa Department of Natural Resources said walnut beetle traps have been distributed all over Iowa state parks, county parks, sawmills, and within communities. The traps are baited with a pheromone card that attracts the beetles.
“This is only a precautionary step,” said Tivon Freely, forest health program leader with the Iowa DNR. “We have not found a walnut twig beetle in Iowa at this time, and it is important to note that not all beetles carry the fungus.”
