G93-1136 Potato Leafhopper Management In Alfalfa, Stephen D. Danielson, Keith J. Jarvi

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains how to detect and manage potato leafhoppers to minimize alfalfa damage.

The potato leafhopper is capable of causing serious damage to alfalfa in Nebraska. This insect overwinters in the gulf states and migrates northward in the spring, usually in April or early May. During the summer months, several generations develop while feeding primarily on legumes such as alfalfa and clover. Although an occasional host, soybeans rarely suffer economic damage, particularly with the pubescent (i.e. hairy) soybean varieties that are commonly grown today. Infested potatoes also can sustain economic damage from this insect. Generally, the potato leafhopper is …

G93-1145 Management Of The Army Cutworm And Pale Western Cutworm, Gary L. Hein, John B. Campbell, Stephen D. Danielson, James A. Kalisch

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the life cycle of the army cutworm and pale western cutworm, and provides recommendations for management.

The army cutworm, Euxoa auxiliaris, and the pale western cutworm, Agrotis orthogonia, are sporadic pests that are distributed throughout the Great Plains. The army cutworm can be found throughout Nebraska, but is more common in the western half of the state. Because of the drier environment, the pale western cutworm is found only in the western third of Nebraska. Both cutworms can feed on a vast array of crops and weeds. Their major economic impact is limited to winter …

G93-1167 Spider Mite Management In Corn And Soybeans, Robert J. Wright, Ronald C. Seymour, Leon G. Higley, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the two common spider mites found in Nebraska corn and soybeans, their natural enemies and management.

Two species of spider mites, the Banks grass mite and twospotted spider mite, commonly feed on Nebraska corn. Banks grass mites (BGM) feed almost exclusively on grasses, including corn and sorghum. Twospotted spider mites (TSM) not only feed on many species of grasses, but also on soybeans, fruit trees and a variety of vegetables and ornamental plants. Although these two species are somewhat similar in appearance, they differ in several biological characteristics and in their susceptibility to pesticides.

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 …

G93-1129 Cockroaches And Their Control, Shripat T. Kamble, David L. Keith

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide provides information on common cockroaches found in Nebraska, and management strategies, including prevention, sanitation, trapping and use of insecticides.

At the height of its popularity many years ago, millions of Americans could hum or sing the song, "La Cucaracha".... The Cockroach. But singing is usually the farthest thing from one's mind when these hardy pests become invaders.

Cockroaches are the most important insect pests in Nebraska households and public places. These insects are oval, flat-bodied, dark colored, with chewing mouth parts, three pairs of legs and usually two pairs of wings. All roaches have three stages in their …

University of Nebraska-Lincoln Extension: Historical Materials

The western corn rootworm (WCR), and the northern corn rootworm (NCR) are among the most economically important insect pests of field corn in the Unitd States. Crop losses and control expenses attributed to corn rootworms annually cost producers millions of dollars. Corn rootworm larvae can cause substantial injury to corn plants by feeding on corn roots.

This Extension circular covers these two corn rootworms, their population dynamics, management considerations, and research/emerging technologies.

Mp92-64 The Stable Fly: A Pest Of Humans And Domestic Animals, Gustave D. Thomas, Steven R. Skoda

University of Nebraska-Lincoln Extension: Historical Materials

Many species of flies are pests. Many people, if you were to ask them about flies, would be at least vaguely aware of the potential to flies to transmit disease organisms. But yet, for the most part, a fly is a fly is a fly. Sayings like "It must be about to rain, the house flies are biting" are still common and show a general need for more, readily accessible information, particularly about some of the pest flies.

Stable flies, obligate blood-feeders, are very important pests to the cattle industry and, at times, are pests to other groups (they're most …

G92-1108 Evaluating Corn Rootworm Soil Insecticide Performance, J. F. Witkowski, Lance J. Meinke, Gary L. Hein, Keith J. Jarvi

University of Nebraska-Lincoln Extension: Historical Materials

This publication describes a technique used to evaluate the relative performance of insecticides in protecting corn roots from feeding damage by corn rootworm larvae.

Insecticides applied at planting or cultivation time are commonly used in continuous corn to protect the roots from damage by western and northern corn rootworms.

Measuring the relative performance of these insecticides in protecting corn roots from rootworm larval damage is important.

G92-1094 Controlling External Swine Parasites, John B. Campbell, Barbara Straw

University of Nebraska-Lincoln Extension: Historical Materials

Mixing, safety, restrictions, and precautions for insecticides used to control external swine parasites.

Hog Lice and Mange Mites

External parasites of swine include the hog louse and two species of mange mites (the common itch mite and the less common hog follicle mite). Excessive scratching and rubbing by pigs nearly always indicate an infestation of hog lice or mange mites.

Hog lice and mange mites infest a high percentage of swine slaughtered at Midwest slaughter plants.

G92-1104 Getting Started In Beekeeping, Marion D. Ellis, Frederick P. Baxendale

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide provides information on beginning beekeeping in Nebraska.

Beekeeping in Nebraska

There are approximately 700 beekeepers in Nebraska operating about 115,000 colonies of bees. Annual honey production in the state ranges from 5 to 11 million pounds depending on weather conditions and available flora. The honey from each area is a unique blend of nectars from the available flora. In a good area under favorable conditions, a properly managed colony can produce 100 pounds or more of honey. The six-year average (1986-1991) for honey production per colony in Nebraska is 75 pounds.

Of far greater importance is the role …

G91-1026 Sunflower Production In Nebraska, James A. Schild, David D. Baltensperger, Drew J. Lyon, Gary L. Hein, Eric D. Kerr

University of Nebraska-Lincoln Extension: Historical Materials

Seeds, seedbed preparations, fertilizing and controlling weeds in sunflowers are among the topics covered here. Sunflowers are native to Nebraska. Cultivated for centuries by native American Indians as a food crop, sunflowers were taken to Europe in the mid-16th century. Oilseed sunflowers have been a U.S. crop since 1986. Sunflower production is divided into two market classes, oil and confectionery. The oil type is by far the most commonly grown market class. Recent health trends have brought sunflower cooking oil into prominence because the oil is low in saturated fats. Confectionery types are grown for the edible roasted sunflower seed …

G91-1061 Conserving Water In The Landscape, Don Steinegger, Frederick P. Baxendale, Garald L. Horse, Dale T. Lindgren

University of Nebraska-Lincoln Extension: Historical Materials

Conserve water in a landscape by following a prescribed sequence in designing and managing the site.

Beauty and utility traditionally have been the purposes of home landscapes. Because water -- in both quality and quantity -- is becoming a limited resource, conservation has become a third goal. The homeowner can achieve all three by using careful, comprehensive planning.

You can reduce water consumption by 40-80 percent by following an appropriate sequence in designing and managing your site.

Ec91-2503 Management Of Fabric Pests, Shripat T. Kamble

University of Nebraska-Lincoln Extension: Historical Materials

The common fabric destroying insects in Nebraska are clothes moths, carpet beetles, and silverfish. Clothes moths and carpet beetles feed on and digest wool, leather, cotton, silk, and synthetic fibers. They generally infest clothes, carpets, rugs, upholstery, etc. Silverfish feed principally on paper products, glue, paste, wallpaper, starch, and any food products consumed by humans. They also damage clothing, cotton, linen, rayon and ramie fabrics.

This extension circular explains these insects and the proper ways of eliminating them in your household.

G91-1022 Guide To Growing Houseplants, Don Steinegger, Frederick P. Baxendale, John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

Proper care can extend houseplants' lives. This NebGuide offers hints on conditioning, light, fertilizing and more.

Many people enjoy houseplants; in fact, raising them is one of the fastest growing indoor hobbies. Caring for houseplants offers opportunities for people who like to work with living things and watch them develop. Today, houseplants are an integral part of indoor decor -- especially in winter.

An artificial indoor environment often hinders plant development. High temperatures, low humidity, lack of sunlight, poor soil conditions, and improper watering contribute to most houseplant problems. In addition, insects or plant diseases occasionally damage houseplants.

While plants …

G91-1023 Insects That Attack Seeds And Seedlings Of Field Crops, Stephen D. Danielson, Robert J. Wright, Gary L. Hein, Leroy Peters, James A. Kalisch

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses how to identify and control eight insects that feed on planted seeds and seedlings.

Planted seeds of field crops can attract several kinds of insects. In many cases, the insects do not cause enough damage to justify control procedures. However, under some conditions seed pests may be very destructive. Seed that is slow to germinate and establish is more likely to be damaged. Situations such as first-year crops following sod or pasture, ecofallow, or reduced tillage/heavy crop residue conditions have a good chance for seed/seedling damage. Consider grower experience and past pest problems when deciding about individual …

G91-1062 Termites (Revised March 2002), Shripat T. Kamble

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide provides information on biology and control of subterranean termites.

Termites feed on wood and serve an important function in nature by converting dead trees into organic matter. Unfortunately, the wood in buildings is equally appetizing to termites and they cause serious damage to residential and commercial buildings. Two species of subterranean termites are found in Nebraska and both species have similar habitats.

Ec91-1556 Subterranean Termites And Their Control, Shripat T. Kamble

University of Nebraska-Lincoln Extension: Historical Materials

Termite damage to residential and commercial buildings in the U.S. costs more than $1 billion annually. Subterranean termites, the most destructive of all termite species, account for 95% of the damage. Subterranean termites occur in every state except Alaska. Two subterranean termite species, Reticulitermes flavipes (Kollar) and R. tibialis Banks, are found in Nebraska. Control of these termites costs more than $1 million each year.

G90-974 The Beaf Leaf Beetle In Soybeans (Revised September 1994), Thomas E. Hunt, J. F. Witkowski, Robert J. Wright, Keith J. Jarvi

University of Nebraska-Lincoln Extension: Historical Materials

The identification and life cycle of the bean leaf beetle are discussed along with scouting techniques, economic thresholds, and cultural control tactics.

The bean leaf beetle is a common insect found in Nebraska soybean fields. The insect also feeds on peas, snap beans, and dry beans. Although present in alfalfa and sweet clover in the early spring before soybean emerges, the insect is not known to damage either legume.

Use integrated pest management (IPM) when planning how to reduce bean leaf beetle damage. Integrated pest management is a sustainable approach to managing pests by combining biological, cultural, physical, and chemical …

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 …

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 …
