Army worms invade Illinois farms, gardens, and meadows

In Illinois, farmers and homeowners are falling prey to the army’s caterpillars.

The pest is found in the Midwest every year, but this year several generations have come from the southern states and Central and South America to lay eggs.

“This is truly one of the worst epidemics of autumn worms we have seen in East America for many years,” said Nick Setter, an oncologist at the University of Illinois Extension Police.

The caterpillars appear brown, green, or black, with light colored lines running from head to tail.

In just a few days, before they leave the field, they walk a long way and get the nickname “Army worm.” They are known for eating alpha, grazing, corn and small grains and can attack grasslands and gardens. In lawns or lawns, the affected area often looks brown or scaly patches that look like drought damage.

The arrival of the pests later this year is good news for soy producers, Seattle said.

“These insects love to feed on tender, growing plant tissue, and you have more soybeans in Illinois today,” Seattle said.

Soybeans are a unique story for the wheat crop. Those fields that are planted late are particularly dangerous.

When the caterpillars are half an inch or less, the fall army’s worm control is better controlled. Sector reported pest failure in Illinois and southern areas.

Illinois continues to lead the country in soybean production according to 2019 USDA estimates. Illinois soybean farmers harvested an average of 54 bushels per hectare over 10 million acres of wild soybeans in 10 million acres in 2019.
