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

Historical Materials from University of Nebraska-Lincoln Extension

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.

Nf526 Spring Millers, Ronald C. Seymour, Gary L. Hein Jan 2002

Nf526 Spring Millers, Ronald C. Seymour, Gary L. Hein

Historical Materials from University of Nebraska-Lincoln Extension

Biology, migration, and management of spring millers.

Millers can be abundant in and around homes each year, especially in May and early June. At this time of year, the moths are most likely the adult stage of the army cutworm, a common pest of wheat and alfalfa.

When millers emerge and begin to move westward in the spring, area residents have little recourse but to patiently await their departure. There are a few tactics, however, that can help lessen moth activity in and around homes:

Keep outside lighting to a minimum. These night-flying moths are attracted to lights. A porch ...

G98-1343 Fall Vegetable Gardening, Dale T. Lindgren, Susan D. Schoneweis Jan 1998

G98-1343 Fall Vegetable Gardening, Dale T. Lindgren, Susan D. Schoneweis

Historical Materials from University of Nebraska-Lincoln Extension

This NebGuide discusses the possibilities for and needs of a fall garden.

Though often overlooked by the gardener, planting vegetables in July and August for fall production is an excellent practice. Late plantings of cool- and warm-season vegetables can extend the harvest long after spring-planted crops have ceased production. Most cool-season vegetables grow as well as or better than those planted in the spring as they mature during shorter, cooler days. Flavors of vegetables maturing in the cool, crisp days of autumn are often sweeter and milder than those grown during hot summer weather. This is especially true for cole ...

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

Historical Materials from University of Nebraska-Lincoln Extension

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 Jan 1996

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

Historical Materials from University of Nebraska-Lincoln Extension

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 ...


G96-1277 Pine Moths, Mark O. Harrell, Frederick P. Baxendale, J. Ackland Jones Jan 1996

G96-1277 Pine Moths, Mark O. Harrell, Frederick P. Baxendale, J. Ackland Jones

Historical Materials from University of Nebraska-Lincoln Extension

Pine moths can seriously damage pine trees. This NebGuide helps you recognize damage and symptoms, identify the pest, and choose a control.

Pine moths are serious pests of pines in Nebraska. Larvae (caterpillars) damage trees by tunneling just beneath the bark of the trunk and branches (Figure 1), most commonly on the trunk just below a branch. The tunnels they make can girdle the trunk or branches or physically weaken them so they are easily broken by wind or snow (Figure 2). Heavily infested trees are often deformed and are sometimes killed.


G96-1302 Managing Varroa In The Midwest, Marion D. Ellis, Frederick P. Baxendale Jan 1996

G96-1302 Managing Varroa In The Midwest, Marion D. Ellis, Frederick P. Baxendale

Historical Materials from University of Nebraska-Lincoln Extension

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 Jan 1996

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

Historical Materials from University of Nebraska-Lincoln Extension

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 ...
