Carpenter Ants And Control In Homes, Jay B. Karren, Alan H. Roe

All Current Publications

Carpenter ants are members of the insect order Hymenoptera, which includes bees, wasps, sawflies, and other ants. Carpenter ants can be occasional pests in the home and are noted particularly for the damage they can cause when nesting in wood. In Utah they are more of a nuisance rather than a major structural pest.

Ec00-153 Selecting Alfalfa Varieties For Nebraska, Bruce Anderson, Michael Trammell, Patrick E. Reece

University of Nebraska-Lincoln Extension: Historical Materials

Yield potential, pest resistance and seed price should be considered when selecting alfalfa varieties in Nebraska.

The most important variety decision on many farms and ranches is the selection of alfalfa. The choice of alfalfa variety affects production for three to 10 or more years, whereas varieties of annual crops can be change every year.

This extension circular lists the alfalfa varieties that have been tested in Nebraska with commercial seed for two or more years since 1997 and marketed in the state. These are the 2000 results.

Nf00-425 Resistance Management For European Corn Borer And Bt Transgenic Corn: Refuge Design And Placement (Revised October 2002), Thomas E. Hunt, G.W. Echtenkamp

University of Nebraska-Lincoln Extension: Historical Materials

One of the key issues surrounding the use of Bt transgenic corn hybrids is resistance management. These corn hybrids have been engineered to produce a version of the insecticidal protein from the naturally occurring soil bacterium, Bacillus thuringiensis (Bt), that is toxic to European corn borers and a few other insects.

This NebFact discusses the important principles of resistance management for European corn borer and Bt corn and refuge considerations.

Scientists at the Animal, Plant and Health Inspection Service (APHIS) have been working for years to determine if beetles imported from China and Kazakhstan would effectively consume tamarisk (salt cedar) in the U.S. without threatening desirable vegetation.

Saltcedar, Tamarisk, Ruth Richards, Ralph Whitesides

All Current Publications

Saltcedar is diffi cult to control. Single treatment approaches to control saltcedar have not proven feasible because no method completely eliminates saltcedar or its regeneration.
