That is VERY interesting info!
Injecting the Tromboncinos with BTK seems to have helped. I didn’t see any new frass today, but did pick a few SVB eggs off, plus two stink bugs yesterday on the Tromboncinos.
On the Cucuzzi front, I’m finally getting lots of female flowers, and not just males. I counted four baby cucuzzi today, and I have one that should be ready to pick tomorrow.
