As there is only one generation a year, and as this species does not breed in dry peas, it is often worth while to hold the seed in bins or sacks until all of the adults have issued. Or the.

The Bean-weevil (Bruclius obtectus).—This is the most common of three or four species of bean-weevils that occur in some parts of the United States. The adults are only about one-eighth of an inch long, dark-colored and short-snouted. Several larvae or bettles may be found in one bean, and they continue to breed in the stored product throughout the year. All infested beans should be fumigated with carbon bisulphide as soon as possible. If the seed is thrown lightly into water most of the infested beans will float. By destroying these one can avoid planting infested Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Kellogg, Vernon L.
