Scouting Watch

The prime phenology plant at this time of year for insect pests is saucer magnolia, Magnolia X soulangiana. It is nearing the end of its bloom in central Illinois and is in mid-bloom in northern Illinois. Bloom is probably over in southern Illinois.

Insect and other pests susceptible to control at this time throughout the state are spring and fall cankerworm, hemlock eriophyid mite, pine bark aphid, spruce spider mite, and Eastern tent caterpillar. European pine sawfly should be present and susceptible to control in southern Illinois. Zimmerman pine moth should still be susceptible to control in northern Illinois.--Phil Nixon
