Pagei 7 1 10 11 Economic importance Control 12 12 â¢. U INTRODUCTION. The injurious stage of the hickory tiger-moth, Ualisidota caryae Harris,1 is a gregarious summer caterpillar (Pis. I. II) which, al- though a general feeder on deciduous trees and shrubs, causes occa- sional injury in orchards of pomaceous fruits and cultivated walnuts. While in this respect it is a minor pest, its injury, where it occurs, is severe and conspicuous and is the source of frequent inquiries to the Bureau of Entomology and to entomologists in the field. The writer's attention was frequently called to the work of this cater- pillar while stationed at North East, Pa., during the seasons of 1914, 1915, and 1916, and there, incidental to the major projects then under investigation, the seasonal history and habits of this insect have been studied and the necessary remedial measures HISTORY. Injury by the hickory tiger-moth was first described by Harris in 3841 (1) in the earliest important work on economic entomology pub- 1 Order Lepidoptera, family Arctiidae. 2 The writer was assisted in 1915 by E. B. Selkregg and in 1916 by James K. Primm. 11190°â18.
