For some, the emergence of the two periodical cicada broods across Illinois went by without a single sighting or rise in decibels. But for others, it was a mass emergence of movement, scent and sound like no other. Dr Kacie Athey’s lab is now requesting fruit growers report any sustained damage to trees, bushes or vines in an effort to assess periodical cicada damage statewide.  The most obvious visible damage would be oviposition slits made by the female periodical cicada on small branches like the one in this photo from a small peach branch (photo credit: Karuna Kafle, Crop Sciences, UIUC 2024).  This could be minor to severe, potentially weakening them to the point of snapping off in the wind.  If you experienced any level of periodical cicada damage to fruit plants, please send your name, location and contact information via email to Karuna Kafle.  The lab will follow up with you to arrange a visit to your operation to access the damage.
