Banks grass mites …

G93-1180 Horn Fly Control On Cattle, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide identifies ways to control horn flies on cattle.

The horn fly is a blood-feeder that feeds 20 to 30 times per day. A population of several thousand horn flies may be present on one animal. When large numbers of these flies are on cattle, the cattle bunch and expend considerable effort fighting the flies. They will often stand in water or seek shade trying to get relief from the flies. When they do this, they fail to graze normally.

Studies in the United States and Canada show that during the grazing season yearling cattle free from horn flies …

G87-838 Management Of Greenbugs In Sorghum (Revised May 1994), Robert J. Wright, Stephen D. Danielson, Zb Mayo

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the identification, biology and management options for greenbugs in Nebraska sorghum.

The greenbug is the most important insect pest of grain and forage sorghums in Nebraska. Although numbers fluctuate from year to year, greenbugs are a limiting factor to sorghum yield in most years. Their management is complicated by the fact that greenbugs have been able to evolve populations capable of overcoming plant resistance and organophosphate insecticides, so best management practices continue to change over time.

Another common aphid found in sorghum is the corn leaf aphid. Corn leaf aphids are often mistaken for greenbugs; however, they …
