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).

Abstract

On the evening of the twenty-third of May many small dark brown moths were noticed flying about a clover field upon the College Farm. They were resting upon the blossoms and among the leaves and upon being disturbed would fly a few paces and then settle again. These moths proved upon examination to be Grapholitha intersinctana, Clemens, the parent forms of the Clover-Seed Caterpillar mentioned in the Entomologist’s report to the Commissioner of Agriculture in 1880. We had during the past winter received specimens of clover-seed which we suspected of being some of the states east of us in the last year or two, and the moths are remembered as occurring here in numbers some eight or ten years ago, but they were not at that time connected with any damage observed in clover fields.
