CRW beetles are flying in corn also at fungicide app time. Insecticide then helps reduce population.

For the OP....also ask any seed company reps in your area if they put out traps in 2024 in corn/beans for RW count. Results there also help you make determinations for next year's seed. 

For 2024, checking with several seed reps in NE IL, it seems most of the traps had 0.0 RW collected.
