Nf05-653 Pyemotes Itch Mites, James A. Kalisch, David L. Keith, Alberto R. Broce

University of Nebraska-Lincoln Extension: Historical Materials

Two North American Species of itch mites — the straw itch mite and the "oak leaf gall mite" (Family Pyemotidae) — are found in Nebraska and Kansas. The straw itch mite was known in the early 1900s as a nuisance pest after farm workers handled small grains. Wheat, oats, and barley were often infested with insects on which the itch mites fed, allowing them to reach large numbers by harvest. The oak leaf gall mite recently discovered in galls on pin oaks in Lincoln, Neb., and Manhattan, Kan., is believed to be a relatively recent introduction to the United States. …

G98-1359 Western Bean Cutworm In Corn And Dry Beans (Revised April 2004), Ronald C. Seymour, Gary L. Hein, Robert J. Wright, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

Western bean cutworm (WBC) can be a severe pest in corn and dry beans. Larval feeding damages both crops through reduced yield and quality. In corn, direct feeding losses may be compounded by fungal and mold infections associated with larval waste products. In beans, damaged or 'worm-chewed' beans are a significant quality factor for both processed and dry bagged beans. Western bean cutworm infestations occur every year in western Nebraska. In some years, this pest is found in high numbers throughout the state.

This NebGuide addresses the life cycle, scouting and treatment of the western bean cutworm in corn and …

G96-1300 Insects That Feed On Corn Ears, David L. Keith, J. F. Witkowski

University of Nebraska-Lincoln Extension: Historical Materials

How to identify mature and immature insects that infest and damage ears of corn.

Several kinds of insects infest the developing ears of corn, raising farmers' concerns and sometimes causing economic damage. Some of these insects can reduce both yield and quality of seed corn, pop corn, sweet corn and field corn. Control decisions depend in part on the economics of the corn crop produced. In many cases, particularly in field corn where the value of the crop per acre is somewhat lower, the insects may not be sufficiently damaging to require control. The higher value of seed corn compared …

University of Nebraska-Lincoln Extension: Historical Materials

There are important regional differences in varroa population dynamics and control. This NebGuide offers recommendations on varroa management for beekeepers in the Midwest.

Varroa management has become an essential aspect of successful beekeeping since the mite was first discovered in the United States in 1987. Unlike most parasites which coexist with their host, varroa eventually destroy honey bee colonies of European descent. A good understanding of this important bee parasite is essential for successful beekeeping.

G96-1295 Scabies, Wayne L. Kramer, Donald E. Mock

University of Nebraska-Lincoln Extension: Historical Materials

The life cycle, symptoms, diagnosis, and treatment of scabies infestations in humans is addressed.

Scabies is a contagious disease of humans and other mammals. It is caused by the mite, Sarcoptes scabiei, which burrows into the dead layer of the human skin (stratum corneum). Sarcoptic mites are obligate parasites which spend most of their lives in burrows in the skin. If the mite invades a person's skin, and establishes itself, symptoms of scabies will become apparent, although it may take four to six weeks.

Scabies is transmitted from person to person by close personal and prolonged skin contact. Transmission also …

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 …
