University of Nebraska-Lincoln Extension: Historical Materials

The Russian wheat aphid is a serious insect threat to small grains. Its description, damage and control are discussed here.

The Russian wheat aphid (RWA) is a serious insect threat to wheat and other small grains. Growers should examine small grain fields regularly for this pest throughout the fall. In the spring, weekly examinations are needed from the time wheat resumes growth through the late heading stages.

G89-954 A Guide For Managing Poultry Insects (Revised April 1996), John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

Major insect pests of Nebraska's poultry population are identified and treatment recommendations are given.

For many years poultry production in Nebraska has consisted primarily of large operations of layer hens. In recent years, however, broiler production has increased in southeast Nebraska. There are also some large turkey production units. Extreme competitiveness in the poultry industry has resulted in narrow cost-profit margins. Poultry operations cannot allow ectoparasitic and nuisance insects to interfere with production, nor can they afford high pest control expenses. For production to be profitable, poultry production must be managed to reduce the incidence of insect pests.

Poultry are …

G89-950 Horse Insect Control Guide, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

Insects that bother horses, and ways to treat them, are covered here.

People keep horses in Nebraska for a number of different reasons. Some are for 4-H projects and urban users (recreational), ranch and farm (work), breeding farms, and racing.

Some of the insect pests of horses are also pests of other livestock species. Other insects are specific to horses, but may be pests only on farm and ranch horses.

The best methods of pest control vary depending upon the type of horse production.

G89-931 Alfalfa Anthracnose, John E. Watkins, Bruce Anderson

University of Nebraska-Lincoln Extension: Historical Materials

Symptoms, disease cycle and control of alfalfa anthracnose are discussed here.

Forage crops are grown on and harvested from more acres in Nebraska than any other crop. Of the almost 49 million acres of agricultural land in Nebraska, approximately 24 million acres are in hay. Alfalfa production has stabilized at about two million acres.

High feed and forage production costs and periodic droughts have generated increased concern by farmers and ranchers over forage losses from diseases, insects and environmental stresses. Estimates suggest about one-fourth of the U.S. alfalfa hay crop and one-tenth of the seed crop are lost annually to …
