During the summer of 2005, adult northern corn rootworms were abundant throughout Iowa. They were common in gardens during the midsummer, they frequented lights around buildings at night, and they were still common on early fall flowers such as thistle. But most surprising was the frequency at which large numbers were found in soybean fields.
