LETTER OF SUBMITTAL. 



Lincoln, Xebr., October 16, 1890. 

 Sir : Herewith is submitted a report of my work in Nebraska for the year as special 

 field agent of the Division of Entomology of the United States Department of Agri- 

 culture . 



In addition to my observations on the general insect depredations within the State, 

 I have incidentally given some time to the study of such insects as were taken upon 

 the sugar and other beets during the summer. 



This special study was undertaken at the suggestion of our experiment station 

 director, who was quite anxious that " beet insects" should be made the subject of 

 a special bulletin to be issued from the station some time during the coming winter. 

 I accordingly include herewith a brief summary of the results of this special study. 

 Yours truly, 



Lawrence Bruner, 



Field Agent. 

 Prof. C. Y. Riley, 



U. S. Entomologist. 



The past summer has not been particularly noted as one in which 

 insect depredators were especially abundant or destructive to the vari- 

 ous crops that are raised in the State. In fact, taking the State as a 

 whole, the injuries from this source have been rather less than is usually 

 the case. Xo one species, so far as I have been informed, has been a 

 pest during the year. The Corn Eoot-worm (Diabrotica longicomis), 

 while it has spread some since my last report, was much less abundant 

 than last year. Cut-worms did not appear in early summer so univer- 

 sally over the State, nor did they do anything near the damage they 

 did the year past. Xo Army- worm depredations have been reported at 

 the station, nor have any come to my own obs ervation ; while the Corn 

 Ear-worm (Heliothis armigera) has been less destructive in most portions 

 of the region along the Missouri River. 



If any one insect has been on the increase and has caused more in- 

 jury than usual, it was the almost universal Codling Moth (at least 

 universal wherever apples are grown or eaten). But if this insect has 

 become apparently more widespread within this region than it was
