Some Papers on Invertebrates

Abstract

IN the report of the Government entomologist, issued by the U.S. Department of Agriculture, for 1910, will be found a full account of the work accomplished during the year under review, and a scheme for future work. Certain points connected with the life-history of the browntail and the gipsy moth engaged attention during the year, more especially the presence of isolated colonies of the latter in woodland districts. As the result of these investigations, it was found that newly hatched caterpillars may be carried by wind to a distance of nearly 2000 feet. Of late years the Argentine ant has caused such damage to orange-plantations in Louisiana that several have been abandoned, but it is believed that a practical method of keeping this pest in check has now been discovered.
