Chinch bug populations continue to increase at a very disconcerting rate. Most corn throughout north central Kansas is far enough along in its development to tolerate large numbers of chinch bugs. Smaller sorghum can still be seriously stressed by growing populations of chinch bugs, especially as the hot and dry conditions return. For more information of chinch bug management in sorghum, please see the KSU 2018 Sorghum Insect Management Guide: https://www.bookstore.ksre.ksu.edu/pubs/mf742.pdf
One relatively mature fall armyworm larva was also detected. Thus, in approximately 2-3 weeks there will be a new generation of fall armyworm larva ready to start feeding, most likely, on sorghum.
