REPORT ON NEBRASKA INSECTS. 
By LAWRENCE BRUNER. 
LETTER OF SUBMITTAL. 
LINCOLN, NEBR., October 16, 1890. 
Sir: Herewith is submitted a report of my work in Nebraska for the yearas 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. €: Vi. 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. No one species, so far as I have been informed, has been a 
pest during the year. The Corn Root-worm (Diabrotica longicornis), 
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. No Army-worm depredations have been reported at 
the station, nor have any come to my own observation; 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 
hecome apparently more widespread within this region than it was
