Wheat Stem Sawfly
Sawfly adults began to emerge in Weld and Morgan counties. Adult sawflies can only lay their eggs in wheat plants with a stem, which would be around Zadoks 32. However, if there are not enough hosts, they may lay multiple eggs per stem or find non-cultivated wheat grasses to lay their eggs.
