There are many species of grasshoppers in Kansas, and not all are crop pests, although most have the potential to inflict damage if present in large numbers. Damage can occur in fall or spring. Typically, grasshoppers invade from field margins as fall-planted wheat emerges. Occasionally,
heads may be damaged before harvest.
Vegetation bordering wheat fields should be inspected 10 days before planting.
Counts of seven to 12 grasshoppers per square yard signal potential problems. Once wheat has been planted, three or more hoppers per square yard within the field can destroy seedling wheat.
None listed.
