"Cornstalk disease" is the name given to the cause or causes of death of cattle allowed to run in fields of standing cornstalks from which the ears have been gathered. It is probable that "many different maladies have been included under this name." In Nebraska, however, there is such a similarity in the symptoms reported by the farmers that it seems probable that the great majority of the losses attributed to cornstalk disease are really due to some common cause. As to the exact nature of this cause nothing is known. However, various theories have been advanced, and methods of prevention or treatment based upon these theories have been described.

Dragonflies are beautiful animals, important predators in and around aquatic environments, and often good indicators of ecosystem health. Stimulated by digital photography, close-focusing binoculars, and many new regional field guides, the study of dragonflies has exploded in the last ten years. Most importantly, the Internet has connected beginners with experts; observers from everywhere now share their experiences. Here is a book that puts it all on paper.

This book offers the texts of twenty-four presentations given in a series of mini symposia organized to commemorate the centennial of Texas A&M's Department of Entomology. Although not stated explicitly by the editors, the central theme for these symposia seems to be the contributions of the discipline of entomology to modern society. The presentations cover a wide range of topics dealing with the importance of insects in both natural ecosystems and agricultural systems; insects as models for scientific research; challenges associated with effective management of those species that are pests in systems designed for food and fiber production; and the role of entomology departments within academic institutions, particularly land-grant universities. The list of contributors to these symposia is impressive, as are the universities and other institutions they represent across the United States as well as in Europe and Africa.
