Areas of Research

Biological Control

Biological control can provide safe, permanent solutions to insect pest problems through the use of natural enemies. Research is currently under way involving the biological control of insects pests of trees, livestock, alfalfa, corn, wheat, and sorghum.


Biotechnology is technology that uses biological systems or living organisms or parts of this to develop or create different products. A simple example of this is using yeast (a living organism) to bake bread). The four types of Biotechnology are: Medical, Agricultural, Industrial, and Environmental.

Field Crops Entomology

Essential food and forage crops often are threatened by insect and mite pests. Minimizing the impact of these pests is a major research objective of the department, with emphasis on pests of alfalfa, corn, dry beans, sorghum, soybeans, sugar beets, and wheat.

Forensic Entomology

The scientific study of insects and their use in legal investigations. Forensic insect evidence is important for investigations of civil, criminal, administrative, and government national security issues

International Agriculture

Focusing on the application of agricultural management and scientific principles to the problems of international food production and distribution.

Insect Resistance to Pesticides

Sometimes insects become resistant or less sensitive to a pesticide that is used to control the pest. Resistance can occur when the same or similar pesticides are used over and over again.

Insect Systematics

Biodiversity, taxonomy, and phylogenetic relationships of insects are of major importance to researchers today. UN-L has excellent entomology research collections that rank in the top 20 collections in North America. Research includes systematics studies on many diverse taxa but especially beetles.

Insecticide/Environmental Toxicology

The impact of pesticides and other toxic agents on insects and the environment are crucial issues. Human exposure, mode of action, resistance development, and environmental water quality are major areas of research.

Insecticide Toxicology

People who use pesticides regularly should understand there may be potential health effects of the products they use. This area of research studies how pesticide exposure may cause acute or chronic toxicity. The four routes of exposure are through skin, eyes, mouth and skin.

Management of Pests affecting Stored Products

Molecular Genetics/Insect Genetics

Molecular, cellular, and organismal mechanisms that allow insects to transfer genetic information from one generation to another are studied in the Department. Efforts focus on resistance mechanisms, biotype formation, and characterization of sibling species.

Pollinator Health

Pollinator Health is essential for ecosystem functioning and food security. Our work in this area is to investigate the underlying stressors and their roles impacting insect pollinators, such as bees and butterflies, that contribute to global pollinator health decline. Outcomes include identifying risk mitigation opportunities, improving public pollinator conservation practices, and best management practices to protect beneficial pollinators in agricultural and natural systems.

Sustainable Agriculture

Farming in a sustainable way to meet society’s present food and textile needs without compromising the food and textile needs of future generations. Practitioners seek to integrated three main objectives into their work: a healthy environment, economic profitability, and social and economic equity.

Veterinary Entomology

Livestock production is a major industry in Nebraska and insect pests are important factors that must be managed wisely. Work on the biology, ecology, behavior, biological control, and pest management of insects of importance to livestock production is emphasized.
