Excerpt from A Manual of Dangerous Insects: Likely to Be Introduced in the United States Through Importations

This publication has been prepared in the Bureau of Entomology at the request Of and in cooperation with the Federal Horticultural B'oard to supply such information as is required by its Officers and others in the enforcement Of quarantines and 'the safe guarding Of this country against foreign insect pests. It Should assist materially in preventing the introduction Of additional pests like the gipsy moth, boll weevil, and alfalfa weevil. Only a. Brief sketch can be given of each of the more important species. The plants making up the commerce in vegetable products are arranged alphabetically by the American common name, with the scientific name following. It is believed that this arrangement is most con venisnt for inspectors. A brief sketch of certain important facts concerning each plant is also given.

The arrangement under each plant of the insects in two or more categories, A, B, etc., is merely one of convenience. Under A are grouped the better known insects, or those concerning which there is available literature. This category especially contains pests which are easily imported. Under B are listed many important pests, possibly sometimes more important than those listed in A and Often just as readily introduced. They are merely listed because full descriptive matter was not available and for other similar reasons. In later editions probably many of these pests will merit fuller discussion.
