Do cicadas destroy crops? What farmers in Illinois need to know

The emergence of two broods of periodical cicadas in Illinois this spring will be an event that has not occurred since 1803 and will not happen again until 2245.

Do cicadas destroy crops?

The short answer is, not much.

“Periodical cicadas don’t pose a risk to any of the major crops in Illinois,” said Illinois State Entomologist Christopher Dietrich. “They are restricted to areas with mature natural forest, and they don’t move around much so we’ll see few, if any, in areas dominated by row crops.”

The Peoria area’s corn and soybeans are safe from a dual emergence of the Northern Illinois Brood and the Great Southern Brood. But the billions of insects whose song will begin to fill Illinois evenings later this month can still pose an agricultural threat statewide.

Do cicadas destroy trees?

University of Illinois Extension horticulture educator Ken Johnson wrote female cicadas will cut open tree branches, resulting in a scar that can be several inches long. While the damage will not kill mature, healthy trees; it can kill small trees and shrubs.

“Newly-planted small trees and shrubs may have trunk diameters small enough for female cicadas to lay their eggs in,” Johnson wrote. “If this happens, the trees can be killed. These smaller plants also have fewer branches on them, and egg-laying can cause significant damage to the trees.”

The female cicada’s affinity for trees means the primary risk is to commercial tree fruit growers. Richard Tanner, the father of Tanner’s Orchard owner Craig Tanner, still helps out at the Speer, Ill., farm, and said 3,000 new trees were planted there last spring. To make up losses from last year, Tanner’s also plans to replant trees this spring.

“Due to the warm and dry conditions of spring 2023, we lost about 15% of the trees and will be replanting them,” Tanner said.

How to protect young trees from cicadas

The Illinois Department of Agriculture said the best way to protect small trees from cicada damage is to surround the trunks with screening, which will curtail egg-laying. IDA said commercially available pesticides don’t work on cicadas and could negatively affect pets and wildlife that feed on them.

University of Illinois Extension assistant professor Kacie Athey wrote late in April that the best protection for vulnerable trees is protective fine-meshed netting. However, for growers with large numbers of fruit trees, there are insecticides available only to commercial fruit producers.

Athey provided a spraying guide for commercial growers, including a list of available insecticides and efficacy ratings for each. Of the eight products listed, five had ratings of “Unknown.” Asana XL and Danitol 2.4EC received scores of “Excellent,” and Athey gave Sevin XLR Plus a rating of “Good.”

Voters had no choice in nearly 9-in-10 primary elections

Voters had no choice in nearly 9-in-10 primary elections



Illinois voting data shows voters had no choice of candidate in nearly 9-in-10 Democratic and Republican primaries for state and federal office in 2024.

Voters had no choice of candidate in nearly nine out of every 10 Republican and Democratic primary elections for state and federal office in 2024.

Analysis of Illinois voting data shows Democrats ran one or no candidate in 135 of the 155 primary elections for the U.S. House, Illinois Senate and Illinois House. That left voters with a choice between candidates in just 20 races.

Meanwhile, Republicans only ran one or no candidate in 137 of the 155 primary elections last year for non-judicial state and federal positions, giving voters of a choice in just 18 races.

In total, there were 155 primaries for the U.S. House of Representatives, Illinois Senate and Illinois House in 2024. Democrats did not run a candidate in 28 of these races while Republicans failed to run a candidate in 50.

And in the 107 Democratic primaries and 87 Republican primaries were only one candidate ran for the position, those candidates secured their spot on the general election ballot with a single primary vote.

To get on the primary ballot for Illinois Senate, the Illinois General Assembly mandates established party candidates to get 1,000 petition signatures from district party members. Illinois House candidates need 500 signatures. For U.S. House, either party’s candidates need signatures from 0.5% of all primary voters from their party in the district.

This lack of choice between candidates for Democratic and Republican party primaries also left general election voters with fewer choices on the ballot.

In the 2024 election cycle, 65 of the 155 non-judicial state and federal general elections had only one candidate on the ballot. That means in 65 districts, it only took one vote for a candidate to win a seat representing the entire district.

Illinoisans already suffer from a lack of choice in candidates. Research shows an average of 4.7 million Illinois voters had no choice in their state representative between the 2012 and 2020 election cycles.

Research shows more choice drives voter participation and makes legislators less susceptible to the influence of lobbyists and special interests. Lightly contested elections also tend to skew policies in favor of powerful special interests.

Illinois should consider reforms that will give voters more choices at the ballot box, such as making it easier for independents to enter the general election like they do in Iowa, Wisconsin and Tennessee.

Until that happens, Illinoisans will continue to see elections with too few choices and too much influence handed to those already in power.

Firefighter faces arson charges after Illinois wildfire burns hundreds of acres


A volunteer firefighter is facing arson charges after he allegedly set a fire in a Lee County wildlife preserve, scorching hundreds of acres.

According to authorities, 21-year-old Trent Schaefer, a volunteer firefighter in Ohio, Illinois, was charged with one count of arson in connection to a fire that occurred in the Green River State Wildlife Management Area Friday.

On that date, temperatures had soared into the 60s, winds were whipping at more than 30 miles per hour, and humidity plunged below 30%, leading the National Weather Service to issue warnings on the danger of wildfires in Illinois.

It is alleged that Schaefer was seen by witnesses getting out of a vehicle and igniting multiple small fires within the nature preserve, which then coalesced into a larger blaze.

By the time firefighters arrived on scene the blaze had already spread, and multiple departments were called in to assist with the fire, including the Illinois Department of Natural Resources.

Firefighters were able to bring the blaze under control by the late afternoon, but not before it burned more than 700 acres, according to authorities.

Schaefer is also a suspect in several other arsons around Lee County, but he has not been charged in any other fires at this time.

Illinois State Police are assisting with the investigation, and no further information was immediately available.
