Ec99-1563 Corn Rootworm Management, Robert J. Wright, Lance J. Meinke, Keith J. Jarvi

University of Nebraska-Lincoln Extension: Historical Materials

Corn rootworms (Diabrotica spp.) are one of the most economically important corn insects in Nebraska. The western corn rootworm, D. virgifera virgifera LeConte, and the northern corn rootworm, D. barberi Smith and Lawrence, are the most economically important rootworm species in Nebraska. A third species, the southern corn rootworm, D. undecimpunctata howardi Barber, causes little economic damage to corn and has not been shown to overwinter in Nebraska. This publication will focus on the biology and management of the western and northern corn rootworms.

University of Nebraska-Lincoln Extension: Historical Materials

Scouting, prevention and control of the iris borer.

This insect is the most serious insect pest of iris in Nebraska and is found virtually everywhere in the state. Damage is characterized by dark, streaked, or watery areas and ragged edges on the developing leaves of iris in May and June and extensive destruction of the insides of the rhizomes in July and early August. Examination late in summer will reveal a large white to pinkish caterpillar from 1 1/2 to 2 inches long in the rhizome, usually accompanied by a foul-smelling soft rot.
