Extension and Experiment Station Publications
It can be very challenging to locate information about individual ISU Extension publications via the library website. Quick Search will list the name of the series, but it will not list individual publications within each series. The Parks Library Reference Collection has a List of Current Series, Serial Publications (Series Publications of Agricultural Experiment Station and Cooperative Extension Service), published as of March 2004. It lists each publication from 1888-2004 (by title and publication number - and in some cases it will show an author name).

Entomology

The Department of Entomology seeks to teach the study of insects, their life-cycles, and the practicalities in dealing with them, for use in the fields of business, industry, education, and public health. The study of entomology can be applied towards evolution and ecological sciences, and insects’ relationships with other organisms & humans, or towards an agricultural or horticultural focus, focusing more on pest-control and management.

History
The Department of Entomology was founded in 1975 as a result of the division of the Department of Zoology and Entomology.

Abstract

Soybean, Glycine max (L.), grown in Iowa and most of the north central region of the United States has not required regular insecticide usage. The soybean aphid, Aphis glycines (Hemiptera: Aphididae), is the most important soybean pest in Iowa and is capable of reducing yield by 40 percent. Nymphs and adults feed on sap within the phloem and can vector several plant viruses. In Iowa, soybean aphids have been a persistent pest that can colonize fields from June through September. Their summer population dynamics are dependent on weather and other environmental conditions.
