Abstract

The farmcrops of Iowa pay a heavy toll annually to insects. While many species figure in this loss to the farmers, a comparatively small number of species are responsible for a very large percentage of the total destruction. White grubs, the larval form of the May beetle, find place among these most destructive forms and if taken over a considerable period of years should likely be ranked most expensive of all.
