abundant in Des Moines and Polk Counties and moderately 
abundant on corn and tomatoes in the central and southwestern 
part of the State. 
C. N. Ainslie (August 13): Field corn in this region 
(Sioux City) shows an almost complete absence of the ear 
worm this year, in fact not a single case of infestation 
has been found during inspection of cornfields. Early sweet 
corn was attacked to a slight degree but much less than 
normally. Corn husks grow compactly this year and this may 
repel the larvae. 
D. Isely (August 22): The corn ear worm is unusually 
destructive this season, in its injury to both cotton bolls 
and corn. The most serious injury noted to corn was in an 
80-acre field in Pulaski County in which the entire grain 
crop was destroyed owing to cutting off of silks by the 
worms, apparently before pollination had taken place. 
LESSEE CORN STALK BORSR ( Elasmopalpus lignosellus Zell.) 
J. R. Watson (August 25): This insect has been rather 
troublesome to cowpeas and other crops. 
R. 17. Harned (August 22): Several complaints have been 
received in regard to injury to cowpea and bean plants. 
These complaints came from Stone, George, and Jefferson Davis 
Counties. Corn plants injured by this species were received 
on August 13 from Durant. 
CORN ROOT APHID ( Anur aphis maidiradicis Forbes ) 
M. H. Swenk (July 15-August 15): The corn root aphid was 
quite injurious this summer in Kearney and Harlan Counties. 
CORN ROOT WORMS ( Diabrotica ispp J 
M. H. Swenk (July 15-August 15): The outstanding entomological 
trouble in Nebraska during the period here covered was an 
intense outbreak of corn root worms ( Diabrotica spp.) in 
southwestern Nebraska. The prevailing species was D. 
virgifera Lee, which did considerable injury in this same 
section in 1927, and a little last year. A considerable 
smaller number of D. longicornis Say were present in the 
region, and an entirely new corn root worm, D. filicornis Horn, 
described years ago from New Mexico, contributed heavily 
to the injury, especially in Chase County.
